DISCLAIMER: I don't own Teen Titans or the Ben 10 franchise.

(Remember this disclaimer because I don't plan on repeating it in every chapter).

For years I've been trying to find a decent Ben 10 and Teen Titans crossover. There wasn't really many good ones out there. With the exception of a few stories written by NegaiFreak, PlutonBlack and GuyverGenesis. But the latter two have been taking SO FREAKING LONG to update their stories I've totally given up hope and thought about starting a B10xTT crossover of my own.

But instead I've adopted one. "Teen Titans: Ultimatrix Chronicle" originally belonged to Stormez the Wolf, but due to personal matters, he put it up for adoption and guess who responded to it in less than half an hour.

Enjoy!

Prologue: GO!

The life of a superhero is filled with danger, adventure and excitement; sixteen-year-old Ben Tennyson, however, was having none of that today. In fact, he hadn't done any heroic work in months! At the moment, the most dangerous thing that could happen to him was getting brain-freeze from drinking his favorite beverages.

The situation on his homeworld had changed drastically in recent months; things had finally calmed down not only on Earth, but throughout most of the universe. The Galvan had given the Plumbers, an intergalactic police force, powerful technologies that allowed them to combat threats that had previously required Ben's help.

Ben was mature enough to know that that was a good thing; there was peace, crime was down, and life was good. Still, a part of him missed turning into an alien every day and fighting some criminal or giant monster. He didn't do any of his heroics for the fame, at least, not anymore; now, he just missed the feeling of helping people.

He'd spent the last couple of years unlocking new aliens and even a few new Ultimate forms on his Ultimatrix, but what good were they if he didn't even need them anymore?

At that moment, Ben walked out of Mr. Smoothie at a leisurely pace, enjoying a chocolate-blueberry combo smoothie. Gwen was close behind him, followed by Kevin who, against his better judgement, had actually ordered one of Ben's suggestions.

"Ugh! I can't believe I let you talk me into getting this!" Kevin complained as he threw away a barely eaten peanut butter-jalapeño combination that despite the appeal of spicy peanut butter was as per Ben's usual smoothie tastes, a horrible combo that left an awful aftertaste in his mouth.

"Don't blame me! You're the one who took my advice. It can't be that bad, can it?" Ben took another long sip of his smoothie as he opened the passenger door of Kevin's muscle car and let Gwen get in. Kevin slid into the driver's seat next to his girlfriend and sighed.

"Guys, could we just have one peaceful car trip without you two bickering over something stupid?" Gwen asked with an exasperated sigh. Ben stopped everything he was doing. "Mr. Smoothie is NOT stupid! Don't even joke like that." At that point, the trio's plumber badges received an incoming signal. It was Grandpa Max, and he sounded worried. "Ben, Gwen, Kevin, where are you? Never mind, the situation is calling for experience, and after your fight with Vilgax, I know you three can handle it. I'm sending Kevin the city's coordinates."

As soon as Kevin got the coordinates, he let out a low whistle. "What is it? Where are we going?" Gwen asked, to which he replied "Jump City. Hang on, we've got a long drive ahead of us."


Meanwhile in the center of Jump City, a green haze rose from the raised crater situated in one of the city's plazas, right in front of a pizza joint where the layout was like a slice of pepperoni pizza. Neon green eyes opening, their glow piercing through the haze, an alien figure with orange skin and long auburn red hair slid out of the crater and to the ground.

Over her forehead and around her face she wore a vaguely M-shaped face guard that stopped around her jaws, and around her neck she wore a silver pauldron with a black broach-like object above her chest. She wore silver shoulder pads, and her arms, stomach, and thighs were covered in purplish segmented body armor. She wore a black form fitting tank top that stopped above where her midriff would be, a black skirt with a silver belt, and thigh-length boots with silver trim around her thighs and likewise soles. In addition to all this, she seemed to have a bulky white and black-trimmed device locked onto her forearms leaving her elbows free, the two matching cylinders held in place by a bolt between the two sides, and at the front were connected by a U-shaped hinge of dark grey metal with a red-armored bolt.

"Slopforn ivortmat!" she growled as she slid down the stone slabs. "Slopforn! Ond gudshik zerrole!" she growled in some alien language, holding her forearms at them while the people gathered backed away seeming to think that the restraint was a sort of weapon. (A/N: I'm winging it with the alien language here...)

Shaken out of his stupor, a pedestrian took a picture with his camera, the flash causing the red-haired alien girl to recoil slightly before her eyes narrowed, a frenzied battle cry escaping he lips as she went on a rampage, swinging her arms around and freaking people out in general as she smashed everything in her path.

This was the scene that Ben, Gwen and Kevin came to as they took in the girl smashing various objects with her restraints, trying to break them off.

"Such strength..." Gwen said in astonishment as they saw the ease in which the girl smashed the things that should take a person three times her size to break.

"Man, two minutes and this girl turns the area around her crater into a complete warzone," Ben remarked.

"She's probably just mad from the long trip or something." Kevin guessed "I know I'd be if I woke up in a crater," he added trying to lighten the mood.

"Not funny, Kevin." Gwen scolded her boyfriend, "But still, why is she so enraged?" she asked.

The figure watched as the green-eyed girl seemed to struggle with her restraints, only to slump forward in defeat. She then perked up a moment later and jumped up next to the support beam that held the pizza joint's balcony aloft and smashed her cuffs against the side of it, plaster sent flying and people knocked out of their seats.

"X'hal! Yark! Mesnef!" she cursed as she swung her restraints into the support column with each curse, warping it with each swing until the pizza slice-shaped balcony broke off entirely, a few civilians left hanging off the edges for standing too close.

The three plumbers were about to take action as the girl was about to take a fourth swing at the abused pillar, only for the sound of metal meeting metal to reach their ears a dual-tone grey bird-like projectile struck the girl in her right temple. Following the direction in which the projectile was thrown she spotted who most likely had thrown it standing atop a car.

"Who are you?" demanded a spiky-haired teen, his hair most likely swept back by hair gel. He wore tight green pants held up by a yellow segmented belt with numerous compartments and a circular black-trimmed buckle, black boots with metal tips, a red vest with green sleeves and a yellow R over a black circle, a black cape with yellow lining around his neck and shoulders, and had green gloves that stopped just short of his elbows. He wore a black and white domino mask, and was most identifiable by his hero persona, Robin, sidekick of Gotham City's 'Dark Knight', Batman.

"Uh…who's the kid in the Halloween coustume?" Kevin asked, not recognising the newcomer.

"I don't know," Gwen asked. "but I hope he knows what he's doing."

The spiky-haired teen's question remained unanswered as the alien girl immediately recognized him as a threat, spinning through the air before bringing her restraints down onto the ground, creating a massive fissure in the process. The alien girl took several swings at Robin, who deftly dodged each swing. Throwing an exploding disk at her after leaping over his shoulder, the five failed to notice the presence of a grey-skinned figure in a dark blue hooded cloak, stopping short of her ankles, she was watching the fight with her amethyst colored eyes.

"Man, that girl must really be riled up about something," Ben remarked as they continued watching the fight, the alien girl effortlessly tossing a car into the air with her right foot before kicking it with a spin, the spiky-haired sidekick ducking to the ground as the automobile spun end over end, flying several thousand feet before it found home in the side of a building. "Why did that car just explode?" he wondered, seeing that it was somehow still intact.

"Hm. Stronger than she looks," Robin spoke seeing how far the thing flew, turning around only for the alien girl to deck him across the face with a wild double haymaker (causing Ben, Gwen and Kevin to cringe), sending him rolling across the ground before coming to a stop, just narrowly dodging another double axe handle into the ground which most likely would've powdered every bone in his body.

"Okay, maybe now would be a good time to intervene." Ben stated as he swiftly activated the Ultimatrix and already found the hologram he wanted. "It's Hero Time!" he cried out before slamming his hand down on the core. Cassie and the Furies were forced to shield their eyes as Ben's body was shrouded in brilliant emerald light. As it died away, standing in Ben's place was a tall, muscular, magma-based life form with dark red rocks over his fiery interior, radiating with heat. His head plumed fire, had shoulder plates that were slightly tipped up from his arms. His feet had an oval-like design, with just two pointed two on each. In addition, he bore the Ultimatrix symbol upon the middle of his chest.

"HEATBLAST!" He shouted in a deep, raspy sounding voice.

"Dude," Kevin gave Ben a slightly annoyed look. "You really gotta stop calling out your transformations names. We already know who they are."

Heatblast glared back at buff teen and countered, "No way! Calling out my aliens names is my thing. Besides, didn't we already settle this? I shout out my names because they strike fear into my enemies."

Kevin folded his arms across his chest and looked at Heatblast with a raised brow. "Uh…no…it doesn't."

Gwen sighed frustratingly as she pinched the bridge of her nose. "If you two girls are done, can we please stop a rampaging alien from causing further destruction!?" She demanded.

"Yeah, yeah, we're on it," Kevin said as he touched the hood of a nearby car and absorbed its properties, encasing his body in metal armor.

Ben discharged a torrent of fire from the soles of his feet, causing his body to blast forward like a rocket towards the battle field.

As the alien girl prepared to assault the costumed-teen again, when the flame-coated fist of Heatblast met with her face; she grunted as the surprise attack sent her tumbling back.

"Why don't you pick on someone with real firepower?!" Heatblast said as Kevin and Gwen caught up with him; the former morphing his hands into sledgehammers and the latter's hands lighting up in pink mana.

Robin was surprised by the sudden appearance of these newcomers.

"Relax, kid, we're on your side." Kevin answered without taking his eyes off the alien girl.

Speaking of whom, she recovered from the Pyronite's attack and glared angrily at the new threats that dared confront her.

Heatblast summoned fireballs in his hands and threw them straight at the girl. The alien stood firm, not attempting to dodge the attacks. She swung her restrained arms and deflected the fireballs with relative ease.

Gwen, now floating on a mana platform, hurled a few mana disks at the alien, who easily withstood the attacks, much to the young Anodites shock.

Kevin lunged at the female extra-terrestrial, but she slammed her cuffs into the Osmosian and sent him careening back into Heatblast.

Robin took advantage of the girl's distraction; quickly whipping out a grey pipe from his utility belt, it then extended into a full bo-staff, which he brought into the side of the girl's head and sent her flying into the air, her body making a dent on the car in her path. The teen whipped out his bo-staff again, only for it to crumble into pieces as though it were made of glass.

"Yeesh, what is that girl made of?" Heatblast asked himself as he saw that.

Wrenching herself free from the vehicle, the orange skinned girl simply cracker her neck to the right with an audible *crack* with a smirk on her face.

"Zota," she said having hardly felt the hit at all and rushing at the with another overhead swing, only for the brown-haired teen's eyebrow to raise as a green mountain goat suddenly came out of nowhere and blindsided her. What really caught them off guard was that the goat then transformed into a little green-skinned teen.

"Ex-Doom Patrol member Beast Boy, Sir! How can I help-" he asked with a salute before growing wide eyed. "Wowzers. You're Robin aren't you sir?" he asked. His attire consisted of a purple jumpsuit with black sides encompassing his shoulders and arms, his jumpsuit's pants styled into purple shorts with the rest of his legs black, with a grey belt with a circular buckle, gloves, around his waist and on his hands. His shoes were segmented purple sneakers with black trim and grey soles. On his mask he wore a grey mask with a purple top, leaving only his green face exposed beneath his eyes, which had dark rings around them like a raccoon's, and overly-large pointed ears like an elf's. His looks surprised the others this newcomer's features had them pondering if he was an alien too.

"Well you can start by not calling me sir," Robin rebuttled.

"Friend of yours?" Heatblast asked Robin as he and his Team approached them.

Beast Boy's eyes drifted to the Pyronite and his eyes were once again filled with wonderment. "No way! You're Ben 19! That guy with the alien watch that lets him turn into alien superheroes?!" the green-teen asked.

"Uh…yeah…that's me." Heatblast answered somewhat taken aback by this kid's over-enthusiasm.

"Great," Kevin rolled his eyes, "Another Tennyson-fanboy."

The green-skinned boy had stars in his eyes as he held his salute. "Well let me just say that it's a real honor to be-"

"Uh, Beast Boy, was it?" Heatblast said getting the teen's attention.

"Yes sir?"

The Pyronite pointed him in the general direction of the girl he'd blindsighted. The others' eyes widened as the alien red-head suddenly lifted an entire city bus above her head, sending it flying at the five teens with a mighty heave. As they hastily dodged, a large figure jumped into the way of the bus and surprisingly caught it, his feet digging trenches across the ground before he set the vehicle down.

"Yo! Who's here messin' up my neighborhood?" the African-American teen shouted loudly. He was extremely tall and extremelymuscular under a pair of black seat pants, a black track suit that showed off his massive build, black boots, and dark grey gloves on his hands. His hood was up and the shadow cast by his cowl hid the majority of his upper face, his left eye glowing red surprisingly.

"Yo! Who's here messin' up my neighborhood!" the African-American teen shouted loudly. He was extremely tall and extremely muscular under a pair of black sweat pants, a grey sweat shirt that showed off his massive build, black boots, and dark grey gloves on his hands. His hood was up and the shadow cast by his cowl hid the majority of his upper face, his left eye glowing red surprisingly.

Ben wasn't sure why, but he reminded him of his old friend Manny Armstrong.

"She started it," Beast boy said pointing to the alien girl as she walked towards them.

"Hraaa-AH!" she shouted as she brought her restraints down onto the street, causing a massive quake to send every car bouncing off the ground and debris to be knocked around by the sudden impact. Standing to full height, the alien girl's restraints fell away, or to be more specific, the outer layer, revealing a second set of restrains in light grey with black trim, a bolt down the sides, but this time revealing her hands, which had violet armor on the backs.

Ben stared at the girl in confusion, "Why would she do that? Unless…"

Raising her hands and clenching her fists, the girl's hands began to glow the same color as her eyes as she aimed them at the six teens; Gwen anticipated what was going to happen next and she knew that the boys didn't have any defense for it. She rushed in front of them raised a pink shield just in time as the alien girl let loose a dual-volley of energy bolts from the ends of her fists towards the six. Gwen grunted as her energy bolts hit the shield with a force that rivalled a missile.

When she stopped firing, Heatblast tapped the Ultimatrix dial, covering him in a green flash. He transformed into a large, tan-colored dinosaur-like creature, standing at 12 feet with a muscular and somewhat humanoid body; he had massive arms, elephantine feet and a tail and the Ultimatrix disk is present on his chest.

"HUMUNGOUSAUR!" Ben's new form yelled in a deep voice after his transformation.

The six teens charged from the smoke towards the rampaging girl, dodging her energy blasts at the same time. Her energy blasts missed us only to hit everything else, cars building, lampposts, and more were damaged in the girl's onslaught. They regrouped behind the bus she threw. She stopped throwing energy blasts only to sink to her knees, likely from shooting so many consecutive energy bolts.

"If we don't stop her soon, she'll level the whole city in the next hour." Humungousaur said.

"Yeah, the dude has a point there." The large guy in the sweat suit agreed as he leaned on the bus

"I won't let her!" Robin answered as he brought his right fist into his left hand. "I won't lose this fight!"

"You're acting as if it's personal," Kevin remarked with a risen eyebrow.

At some unspoken command we all charged from our hiding place, only for a massive raven-shaped silhouette of dark energy to suddenly rise out of the ground in front of them, screeching into the air and halting their advance before a new figure materialized from behind them, seemingly out of the shadows themselves.

"Maybe, fighting isn't the answer," a quiet, purple-eyed grey-skinned girl said as she walked towards them. Over her body she wore a dark-blue cloak that went down to her ankles, a black and gold broach on the left, the cowl of her hood hiding the upper portion of her face, the only other visible part of her being her blue-clad feet.

Kevin shook his head, "This night just keeps getting weirder and weirder," he sighed as the silhouette dissolved.

Humungousaur then looked at the kneeling girl as her hands still steamed from her attack.

Touching the Ultimatrix dial, Ben reverted back to his human form. "Stand down." Ben ordered. Gwen and Kevin complied while Beast boy saluted. The sweat suit wearing teen did not seem to like this and voiced his displeasure.

"What, you think you're the boss or somethin'?"

"Trust me," Ben insisted, "I think I can calm her down."

The boy backed down while Robin remained silent, wondering if this brunette knew what he was doing.

"Be careful, Ben." Gwen advised "She seems to have culture shock, added to that she seems not to understand English." The red-haired girl added.

Ben nodded at his cousin's advice and walked towards the kneeling girl who was panting. The girl then stood up and raised her arms, fists starting to glow green as she took his advance as a threat causing Robin to back up and raise his hands in a calming gesture.

"Easy, my name is Ben, and I just wanna help..." the Ultimatrix bearer said; while it is true that she may not understand English, maybe the tone of his voice will help.

Growling slightly, the alien girl was about to spring into action again, only to meet his endearing smile and falter, her eyes ceasing to glow, revealing them to be a light green through her sclera, her irises a shade of emerald green.

Next thing she knew, she could now move her arms freely. She looked down at her feet to see that Ben had removed her inhibitor cuffs.

The Ultimatrix bearer was no stranger to alien-based cuffs and knew (with lessons from Kevin of course) how they could be removed without a key.

"There. Now that you're free, can you tell me who had you-MMF?!" Ben said only for his words to be muffled. The others' eyes widened as dinner plates as the alien girl suddenly pulled him into a kiss by the back of his neck, her eyes closed as Ben's widened before she suddenly pushed him away, the surprised Ultimatrix bearer landing on his butt.

"If you wish not to be destroyed, you will leave me alone!" the alien girl suddenly growled out in English before flying away.

Silence took hold on the street before Beast Boy broke it.

"So…I'm Beast Boy. Who're you?"


A few minutes after the initial shock of the alien girl's departure, wanton destruction all around, the group broke out of their stupor.

"Who was that girl?" Gwen asked.

"Well, whoever she was, the girl knows how to make an impression," the African teen stated.

"I think we made a pretty good impression," Beast Boy said with a grin. "Crazy space girl's gone, the city's saved. Mission accomplished."

Kevin snorted "Yeah, an entire street in ruins and other damages throughout the city, that's a great first impression." He said sarcastically.

Robin spoke as he began walking away and said, "Looks like we're done here, I appreciate the help."

"You're going to track down the alien?" The cloaked-girl asked in a monotone voice.

"I have to find out if she's a threat."

"We better go too." Ben said as Kevin and Gwen were at his sides.

"Why? So you can get another kiss?" the larger teen asked snidely.

"No…" Ben said simply, though he was mentally blushing like crazy from being kissed by a girl he had only just met. "It's our job to deal with any alien activity that threatens the public." He explained before turning to his cousin. "Gwen, can you track her."

The Human/Anodite's eyes briefly glowed pink as she replied, "Yes; she left her mana all over the place. She hasn't gotten far."

Nodding, Ben quickly slammed the dial down and was instantly engulfed in a familiar green light. In nanoseconds, his body transformed into red manta-ray like alien with the underside of his wings being colored yellow.

"JETRAY!"The Aerophibian shouted as the light died away.

"Do we really have to fly Tennyson Airlines again?" Kevin whined.

In a swift motion, Jetray hovered off the ground, grabbed Gwen and Kevin with his feet before any other compliant or remark could be made. In seconds, Jetray was soaring high into the morning sky, and quickly making ground towards the little small town in the distance.

"Up, up, and away!" The red manta ray alien exclaimed as he shot off into the distance where the alien girl likely went.

Beast Boy ran up to Robin and asked, "Sir, I mean Robin, I was wondering if you..."

Robin interrupted him and said, "Sorry I just went solo, I'm not looking to join a team."

"…need a sidekick?" the green-skinned boy asked scratching the back of his head before turning around. "You guys wanna get a pizza?" he then asked the other two animatedly.

"I shouldn't..." the cloaked girl said walking away, leaving the green-skinned boy to go after the large African teen.

"Just you and me then huh? Cool. I-I haven't really had anyone to hang out with since I quit the Doom Patrol," he said following him. "This is going to be fun. Can we play video game-" he was about to ask only to be interrupted when he bumped into his back as the teen stopped.

"There! Take a good long look!" he said pulling away his hood, revealing the left side of his face down to his jaw to be covered in grey metal, the top of the left side of his head, the side of his right, and the left side of his neck inset with dark and light blue mechanical parts. "I had an accident, and now I'm a monster alright. A cyborg."

"Cyborg? Cool! You're like Robot Man 2.0!" Beast Boy said happily looking the teen over from multiple angles.

"You're a weird little dude you know that?" he asked flatly.

"Hehe. You called me dude," the green teen returned with a smile. "Okay, so... see you later. Right, dude?" he said as the cyborg pulled his hood up and started walking away. A few seconds later however, a massive silhouette moved through the sky, causing Beast Boy to call out "DUUUDE!" loudly as the red and orange-trimmed ship of alien origin flew over the city towards the island in the center of the bay.

Shortly after the alien ship had shown up, a large orange-armored torch the size of the Statue of Liberty's was jettisoned onto the island in the center of Jump City Bay.

"Looks like space girl has friends." Cyborg said as he saw this

"Or enemies..." Robin said as he walked up to them.

After touching down, a massive hologram, so large you could see it from every point in the city was a giant, ugly, reptilian fish-like alien covered in dark green scales and off-gold armor.

The lizard-like alien began to speak, "People of Earth, we come to your planet looking for an escaped prisoner, a very dangerous prisoner. Do not interfere and we will leave your city with only minimal damage. But if you attempt to assist her your destruction will be absolute." The image faded away as the doors to the capsule opened.

"That's a big ship..." Cyborg said as the torch seemed to open to reveal more of the lizard-like aliens.

"And those are some scary looking aliens..." Beast boy said as they took off into the city to search for their prey.

"They told us not to interfere." The grey-skinned girl said

"You're still going after her, aren't you?" The hooded teen stated rather then asked as Robin nodded.

"Can we come too?" Beast boy asked hopefully.

"...I suppose I could team up, just this once." Robin answered smiling which caused the rest to smile back and follow, but the grey-skinned girl hung back with uncertainty.

"You in?" Robin asked as he noticed that she hung back.

"...I'm not the hero type." The grey-skinned girl said turning away "Trust me, if you knew what I really am, you wouldn't want me around..."

That statement caused the hooded teen to frown under his hood as he recognised what she was feeling, loneliness... He then touched the girl's shoulder surprising her.

"We know enough." The hooded teen said smiling which made her give a small smile back.


Joining together, the cloaked girl explained that she was near after the group had watched a few of the reptilian fish-like alien's rather questionable searching methods if they intended to only leave "minimal damage". The cyborg of the group had pulled back his right sleeve, revealing that it followed the same design template as his head and neck, and explained that he had a built in sonic analyzer. In addition, Beast Boy transformed into a blood hound before sniffing around as he dragged his snout along the alleyway ground. As the green-skinned teen caught the girl's scent, the cyborg said he'd found her heartbeat, the group running down the street towards a video rental store. So, imagine their surprise that when they get there that who else, but Team 10, do they run into, standing by a melted hole in the rental store wall. Ben waved over to the group.

"Hey guys!" Ben called from beside a melted hole in the wall of the video rental store. "She's in here," he elaborated, the four looking over his shoulder to see the alien girl stuffing her face full of all sorts of snacks from the video rental store. To be frank, her manners were atrocious, though maybe that was the normal on her home planet. God how right he was.

"And you're not worried about the aliens?" the cloaked girl asked poignantly.

"You mean fish-face on the jumbo non-existent screen?" Kevin asked rhetorically before he scoffed "He obviously hasn't dealt with us before," he said crossing his arms.

"So then you know what you're getting into?" Robin asked.

"Five bucks says we'll have to storm the alien mothership, kick some alien butt, and take down their ship before sunrise tomorrow morning," Ben said confidently but with a hint of wisdom.

"Alright, let's get in there. She can't do this on her own," Robin said as he led the group into the store, the alien girl having dug through a few hundred dollars-worth of over-priced snacks before Beast Boy saw fit to speak up.

"Uh… Those taste better without the wrapper," he quipped somewhat nervously.

The alien girl ceased her ravenous consumption, rounding on them with balls of glowing energy in her hands, causing them to go on guard.

Ben put his hands up and said, "It's okay, were friends remember?"

"Friends? Why? For what purpose did you free me?" she asked as she stalked towards the group with glowing hands, the seven teens backing away cautiously.

"Just…trying to be nice." Ben said awkwardly.

"Nice...? We do not have this word on my planet. Closest is rutha. Weak," she hissed with glowing narrow eyes.

"Well, around here, nice means nice, and if you want us to keep being nice, then you're going to tell us why the lizard king took you prisoner," the cyborg of the group said standing up to her.

"Not prisoner. I am... prize," she said as her hands and eyes ceased glowing as she adopted a saddened pose. "The Gordanians deliver me to the Citadel. To live out my days as their servant."

"And the Citadel are..." Gwen asked, trailing off as she waited for an explanation.

"Not, nice," the girl returned evenly.

"Then you're not going with them. Not if I have anything to say about it," Robin stated giving her a thumbs up.

Um, don't you mean we?" Beast Boy asked before the side of the building exploded inward, the place being swarmed with reptilian fish-like aliens moments later. At the shout of "Seize her!'", the aliens flew forward, intent on reclaiming their prisoner.

Instinctively, Ben selected a form on the Ultimatrix hologram library and slammed the dial. A green flash of light consumed Ben's body. His height increased to over 6'5'' as his skin color turned to an assortment of blue and black. When the light died away, an anthropomorphic moth with the Ultimatrix dial present on his chest stood in Ben's place.

"BIG CHILL!" Ben said in a cold, eerie voice.

At an unspoken command, the gathered eight teens charged into battle took on their own number of the lizard-like aliens. The group's cyborg struck his alien with a double axe handle, Beast Boy transformed into a rhino and sent several flying into the air off the end of his charge, the alien girl decked a dozen or so with a super-powered punch, Kevin bashed his share of enemies with hands morphed into maces, Gwen unleashed a barrage of mana-bolts at the lizards, Robin knocked a few away with a kick and another bo staff, the cloaked girl sent several others flying with her dark powers, and Big Chill exhaled his icy mist freezing them on the spot.

The battle continued outside as Robin saved the alien girl from being impaled. Gwen was forced to project a mana shield to prevent most of the lizards from reaching her. Kevin the nearest lizard's lights as he watched Beast Boy, now as a panther, make quick work of two other aliens. More Gordanians tried firing at Big Chill, only for the moth-like alien to turn intangible allowing the blasts to harmlessly faze through him.

"You can't touch me," Big Chill smugly informed them with folded arms, "But I can touch you!" the Necrofriggian flew straight through the flying lizards, freezing them in ice within seconds.

The African teen, after grappling with his and being forced to the ground, rolled out of the way before flipping and landing, only to be pelted with energy attacks. When the smoke cleared, his full form was revealed, showing that only his biceps and the majority of his face were still organic. He had semi-transparent components on his thighs, forearms, and shoulders, while the rest of his body was white and grey with black armor underneath and grey trim separating his body's components. Clearly angered by the loss of his outfit, he leapt at one of the aliens and broke its spear before throwing it into several others.

He found himself backed into a corner as more Gordanians continued firing at him. Big Chill, who had just made a seventeenth lizard-sicle, noticed his predicament. He touched the Ultimatrix dial and he morphed into a six foot tall being whose body appeared to be made entirely of purple rock, with several dark lines and spots. His hands and face are magenta, and he also sports six magenta shards on his back, two on his chest, and one on the top of his head that resembles a horn. His face consists of a mouth and one large green eye at the centre.

"CHROMASTONE!" the new form of Ben proclaimed.

The Crystalsapien jumped in front of the cyborg, allowing the energy blasts to hit him instead. But instead of causing him damage like the soldiers expected, Chromastone absorbed them!

"That's not gonna work on me fellas." Chromastone informed them with a smug smirk. "I'm an energy conductor!"

Without giving the lizards a chance to process this revelation, Chromastone gathered raised his hands up and discharged a multi-colored blast of energy at the assaulting Gordanians, knocking them out of the air.

To finish the battle, the cloaked girl ripped a lamp pose out of the ground with her powers, which gave it a black aura before she used it to send a few of the aliens flying away and to the ground. Looking up in defeat, the aliens quickly flew off into the night sky, leaving the eight teens to get back together after the battle had been done; Ben assumes his human form again and Kevin's armor fades.

"I believe your expression is... thanks," Starfire said, sounding rough at the beginning, but endearing at the end.

"Aw man, my suit," the cyborg of the group groaned as he tugged at the tattered remains of his clothing.

"So? You look way cooler without it," Beast Boy said with a grin and a thumbs up.

"Yeah. Like I'm taking fashion advice from the kid in the goofy mask," Cyborg replied snidely.

Beast Boy looked hurt as he asked, "Goofy? My mask is cool." Looking to us he asked, "Isn't it? Guys?" the cyborg, Raven and Kevin shook are heads in the negative. Looking hurt he asked, "But, what about my secret identity?"

"What secret identity? You're green." Raven pointed out flatly.

"Yeah that's kind of hard not to miss." Kevin agreed.

The green-skinned teen searching for a response only to come up with none; he removed his mask revealing a head of short spiky hair a moment later, his ears normally-proportioned despite what his mask portrayed.

"This isn't over. Now that they've interfered-" Robin took over before the alien girl continued.

"Trogaar will strike harder. It is only a matter of-" she said only to be interrupted by another hologram appearing in the sky above Jump City.

"Fools! The Earth scum have been warned. Your insolence will be punished. Your city… shall be destroyed!"the alien the group assumed to be Trogaar stated before the hologram faded, the massive alien ship flying over the middle of the city as a massive orange-armored particle beam cannon extended, glowing brightly as it began to charge and caused people to scatter in every direction like scared rodents.

"That's a biiig gun," Kevin stated with a slightly slack jaw, while Raven only nodded in agreement since it wouldn't be worth it to comment further. The brunette's own statement did so enough.

"So…After trashing the pizza place and a perfectly good video store, now we've managed to make a humongous space gecko mad enough to vaporize our entire town?" Beast Boy asked in shock.

"What do you think?" Kevin asked rhetorically.

"Go team." The cyborg added sarcastically.

"All the fault is yours. I commandedyou to leave me alone, but you insistedupon being nice!" the alien girl growled at the spiky-haired teen.

"My fault? You blast me! Kiss me-"

"Technically she kissed me," Ben pointed out raising a hand.

Robin ignored him, "But you never stopped to mention that they had a gigantic particleweapon!" Robin demanded as red lightning arced between him and the alien "escapee". Things soon quickly degenerated into childish arguing between Beast Boy and the cyborg, Raven and Team 10 being the only ones left out before both Gwen and Raven yelled out.

"QUIET!"

Everyone stopped arguing to look at us. Raven smiled sheepishly and said quietly, "Hi."

"Hmm, she must not like being in the center of attention." Ben thought to himself.

The not-so-nervous Gwen spoke, "In case you guys forgot, a tyrannical alien-lizard plans to blow up the city whole. So are you all gonna stand around pointing fingers at each other like kids all night, or are we going to do something about it?" she demanded.

Robin sighed, "She's right; look it doesn't matter whose fault it is, what matters is that we're in it and we will get out of it together." They all smiled and nodded in agreement. Smiling Robin said, "Come on, we got a city to save."

Beast Boy asked, "Uh, how are we going to get on the ship?"

Raven answered, "I can teleport us there."

"Do it." Robin instructed.

Nodding, Raven surrounded us in her dark energy and the next thing they knew they were aboard the alien ship.

"Ugh… that dark energy stuff gives me the… uh, I mean… It's cool!" Beast Boy said, giving Raven a thumbs up.

"Niiiiice." Kevin responded sarcastically to the green skinned teen's quick recovery.

"We have to get to the firing controls. There isn't much time." Robin said to the other seven as they began to sneak down a corridor. Then Gwen noticed Raven had stopped following them.

"Mind telling me why you're always by yourself?" she asked the robed teen.

"You heard the kid… I don't exactly fit in." she said, seeming a little more downcast than usual.

Gwen put a hand on her shoulder. "He's green, two of us are half alien, one of us is half metal, one of us has a plethora of aliens at his disposal, one of us is from space. You fit in just fine." Raven decided that now wasn't the time to question her new friend on what she meant about aliens and simply nodded, thinking she would ask later.

The orange skinned girl, who by this time had gotten used to her strange company, directed her attention to Robin "I bring you… apology." She stated, unsure of how he would react.

"Don't worry about it. I'm sorry I yelled too." Robin said.

The alien girl continued "And, again, you are all very… nice. On my world only my Knorf'ka has shown me such kindness."

"Well things are different here, but we shouldn't be stopping to chat, because if they didn't know we were here before, they do now." Ben interjected as he raised the Ultimatrix dial and thought ~skip the catch phrase, it would attract unwanted attention.~ as they were surrounded by the lizard aliens.

"Take them out, team." Robin said as, on a hunch, Raven raised a necromantic shield around her and Ben. "Thanks." He said as he slammed the dial down. He was now a semi-armored Velociraptor. He had black wheels on his feet and wore a helmet with a visor, leaving the other features of his head unknown, with the exception of his blue face, green eyes, black lips, and stripes above and on the right side of his eyes. He had five blue stripes on his tail and the Ultimatrix symbol is on his chest.

"XLR8!"He hissed in a raspy voice that sounded like he had a sore throat.

Raven then lowered the shield and using his ability to manipulate friction, XLR8 took off in a black-and-blue blur, assaulting the remaining Gordanians. Thanks to the Kineceleran's speed, the lizards couldn't react in time as they were taken out in 2.3 seconds.

Once the deed was done, Ben turned human again he picked up one of the alien spears and said "I think I'll keep the element of surprise."

"Dude, are you always this resourceful?" Beast Boy asked dumbfounded.

"Eh... so and so." He responded. When they found the bridge of the ship, they saw that it needed a key card, and Robin was more than happy to bring out an explosive. Then Gwen got an idea. "Why don't we just have Ben use Grey Matter to hack into the door mechanism, instead of blowing up the ship?"

"Who is this Grey Matter you speak of, and how did you manage to be a kineceleran?" The orange skinned alien girl asked him. She was very interested in what this human could do, but she was still cautious. Team 10 was surprised that she recognized his form, and knew the term to match. Robin took the liberty to use Ben's stunned face as extra time to blow the door open.


"-it takes more than eight juvenile heroes to defy the mighty Lord Trogaar." They heard the leader, apparently Trogar himself, say as they entered.

"We're not eight heroes, we're one team." Robin said confidently.

"Since when did I say I was part of a team?" Kevin asked, annoyed that no one had asked his opinion, as he absorbed the red metal that the ship's hull was made of.

Ben swiftly activated the Ultimatrix and already found the icon he wanted. When the core popped out he slapped it back down. His body was shrouded in brilliant emerald light. As it died away, standing in Ben's place a seven-foot tall creature that seemed to be made of a green, plant-like material. His head was a red and yellow flame pattern.

"SWAMPFIRE!" he yelled; due to not having a nose, his voice sounded stuffed and nasally. "Hit 'em hard, hit ém fast."

Everyone gladly obliged and charged at the Gordanians; Robin flew into a kung fu kick and decked an alien, while the cyborg used the shockwave off his double axe handle to sent another two flying. Beast Boy had transformed into a kangaroo and delivered a double kangaroo kick, and the alien girl knocked out another one with a dynamic glowing-fist uppercut. Kevin decked the lizards with his hands morphed into a mace and sledgehammer, Gwen fired off concentrated blasts of mana while Swampfire discharged two dense streams of fire and the aliens, sending them scattering.

Beast Boy ran, or rather bounded over to a group of the aliens as a kangaroo, taking them out with his powerful legs, but was knocked against the wall after one of them landed a powerful punch. Raven used her dark powers to appear in front of Beast Boy's attacker and put up a small shield to repel his punches.

When her shield failed on her, Robin used the opportunity to jump onto her attacker's back. A punch to the face and roundhouse kick later, the Lizard alien grabbed him around the torso and threw him across the room, where he was grabbed mid-air and set down by a hand, made of pure mana energy.

"What the?" was all he could get out before he had to get back into the fray. The orange skinned alien shot strange green bolts of energy towards Trogaar as he began to run towards her, only to be stopped by Cyborg and Kevin, who were both more than glad treat the alien tyrant to a series of hard punches. Unfortunately, they were both knocked backwards by the force of his own, harder punches, and she was grabbed and forced onto the floor, struggling to get free.

"He, fishface!" Trogaar looked to his right to see Swampfire sprinting forward with his fist reared back and jumped up to deliver a powerful blow into the Gordanian leader's face. The lizard warrior went flying back and crashed into the wall of the ship.

Trogaar recovered, and with a vengeful snarl, he lunged at the opposing Methanosian, who did likewise. Swampfire threw another punch, but Trogaar evaded it this time and with his extended claws, he sliced off Swampfire's outstretched arm.

"BEN!" Robin yelled, worried his new teammate just received a fatal injury, until he saw something unexpected happen. A vine grew out of the stump in Swampfire's arm and connected with the severed limb, the limb was then pulled back into the socket and reattached itself. The transformed teen gave a smug grin as flexed his reattached arm.

"My turn." The Methanosian formed flames in his hands. Trogaar was so stunned that he didn't have time to dodge. The torrent of fire hit him square in the chest, sending him hurtling to the ground. Swampfire thought that was the end of it, but Trogaar got back up, his face full of rage.

Swampfire groaned at his enemy's stubbornness and noticed that more and more Gordanians were entering the battle; the teens were practically swarmed with the entirety of the bridge.

"Gonna have to step things up a notch," Swampfire noted, "Time to go Ultimate!"

He lifted his right hand and slapped the Ultimatrix dial on his chest, causing four clamps to stick out from the rim. An emerald flash illuminated the room as an evolutionary surge filled Swampfire's body. The result dumbfounded everyone minus Kevin and Gwen: Swampfire grew an extra foot taller and now bared the resemblance of a humanoid tree. His body was now comprised of dark brown, petrified wood. On his hunched back were three blue, gooey shells and his flame-patterned head was inside one of the frontward facing shells. The new form of Swampfire bent his arms by his elbows and shouted out his new name.

"ULTIMATE SWAMPFIRE!"He bellowed out.

Taking advantage of Trogaar's stupefied expression, the hyper-evolved Methanosian brought his hands forward unleashed an enormous torrent of azure flames upon the Gordanian tyrant. The force and intensity was enough to blast him away while he roared in intense pain as the flames scorched his body.

But Ultimate Swampfire didn't stop there, he pulled off some blue, gooey balls from his forearm and tossed them at the feet of another Gordanian horde. Upon hitting the floor, they ignited into blue fireballs and sent them careening back. The teen hero ran forward, tossing countless 'grenades' at his enemies, which quickly subdued them. Needless to say, Robin and the others were impressed.

Ultimate Swampfire then noticed that a few more Gordanians were charging right at them with their weapons poised to strike! So he threw some small seeds at their feet, and like something out of an overactive greenhouse, thick vines grew out from under the lizard aliens. These vines did their job just fine, and trapped the Gordanians in an unbreakable mass of wild foliage.

"Can you rewire that into some sort of weapon?" Robin asked as he, Gwen, the cyborg, and the alien girl were cornered.

"I can try," he replied before ducking, Kevin being sent over his head and into the nearby wall by one of the alien's uppercut, said aliens soon surrounding them, only to stop as a soft-spoken voice got their attention from behind.

"Get away from my friends," Raven then said as she helped Beast Boy up. "Azarath, Metrion, ZINTHOS!" she called out as her eyes glowed white within the cowl of her hood, the resulting explosion blowing out the cockpit's roof and cancelling the particle weapon's charge, the sudden loss of control causing the ship to crash into the bay.

Getting up a few seconds later, a smouldering Trogaar walked towards Raven and Beast Boy, his claws extending as he raised his arm to strike them down. Eyes narrowed, Ultimate Swampfire prepared to hit him with blue fire again, only for a blue and white-ringed beam to come off the cyborg's arm and strike the alien leader in the back, causing him to grunt in pain and fall flat on his face, Ultimate Swampfire sighed as he allowed the blue flames in his hands to dissipate.

"Alright, I'm only going to say this once," he said raising his arm, which was now configured into some kind of sonic cannon. "Booyah."

Kevin gave Beast Boy a high five, nearly knocking him over as he forgot he was still covered in metal.


After the battle had ended, with the aliens taking their working shuttles off the planet after their warship was grounded, the four heroes, the alien girl and Team 10 found themselves on the coast of the island in the middle of Jump Bay facing the east, the sun rising in the distance. The alien torch had been left behind, clearly only meant for one-time deployment until it was retrieved and re-fitted for future use.

"That's quite a view," Raven said, her hood down revealing purple shoulder-length hair, angular eyebrows, and a red gemstone on her forehead. Her cloak was now hung at her shoulders, revealing a black leotard, black armlets, blue wristbands, and a pair of broaches on the backs of her gloves, while her belt was made of likewise broaches.

"Somebody outta build a house out here," the cyborg stated with crossed arms.

"Yeah. If you like sunshine, and the beach," Beast Boy said tapping Raven with his elbow.

"Hmhm. You know, you're kinda funny," she said with a ghost of a smile.

"You think I'm funny? Oh-hoho. Dude, I know some jokes!" the greenette said with diamonds in his eyes, the purplette quickly regretting egging him on like she did.

"Keep the jokes to a minimum and I might let you off without a warning punch." Kevin said aggravated. Then he addressed Gwen "And my car got destroyed in the attack, along with our plumber badges so it looks like we're stuck here until we can contact your grandpa, babe."

Ben suddenly asked as if out of nowhere "Did anyone see where the alien girl went?" he looked around a bit before the subject of his question stepped up from around a rock and approached the group.

"Please, I look... nice?" the alien girl asked, revealing an outfit change. Most of her armor had been cast off except for that around her neck and forearms, revealing a fair deal more skin. Her tank top and boots which were silver-trimmed were now purple, and on her right bicep she wore a silver arm band. The M-shaped crest on her forehead was also gone, revealing a pair of small eyebrows that matched her hair, overall really bringing out her eyes and giving her an exotic look.

"I…still don't know your name," Ben stated after taking in the girl's appearance.

"In your language, it would be Starfire," she said walking towards them.

Robin stepped forward, "Welcome to Earth, Starfire."

I thank you all for your bravery and help, and I wish to ask permission. To remain here, where the people are most... strange, but also most... kind," Starfire said warmly.

"You don't need our permission," Gwen said kindly.

"But if you want our friendship, you've got it," Ben added.

"I guess we could all use some new friends." Cyborg admitted.

Kevin grumbled "Well my car did get destroyed, so I'm stuck he- owww." He got elbowed by Gwen.

"Besides," Beast Boy added, "we kinda made a good team. Right Kev?"

"It's Kevin, not Kev, but it was pretty fun to beat those lizards senseless." Kevin let a laugh escape his lips.

"Is he always like this?" Robin whispered to Gwen. "You get used to it." She answered.

"I thought we might want to keep in touch, so Cyborg and I designed these," Robin said holding out six circular yellow walkie-talkies, black trim along the bottom, side button, and a black antennae with a red button on the side.

"Made them outta my own circuits," the now-dubbed Cyborg said proudly with crossed arms.

Kevin then held out one of the off-yellow spear-like weapons of the Gordanians by his side. "Plus we got a souvenir out of this. Sweet."

"Uh... I'd watch where you point that thing if I were you," Raven said, placating him.

"Why? Who could possibly be hurt out here?" the half-Osmosian asked setting one end of the spear down, a blue bolt flying off the end before choom-squawk-a seagull was shot out of the sky, smoking and twitching slightly as Kevin rubbed the back of his head slowly. "Um... Maybe I'll just go and see what I can salvage from the ship. Hopefully a user's manual," he said nervously as he held the weapon behind his back and walked over to where the ship crashed.

Gwen sighed, "I better go with him." She said following her boyfriend.
