Season 2; Chapter 9: Assemble The Ultimate Negative Ten


Six Months Later

In the vast Sahara desert, a giant sabertooth was treking through the dunes heading towards a small remote village. It was yellow with black spots scattered around it's body. It had blue eyes with black slits in the middle, with two large fangs sticking out from its mouth. In a plane, ten thousand feet above, was a large grey plane with the initial's HA on it. The Hero Association, the greatest defense that mankind had against the monsters.

Inside the plane, a boy stood before the airplanes hangar door, he had brown shaggy hair that seemed to be slicked back a bit. He wore black and white converses, black ripped jeans, a black short sleeved shirt with a hood attached to it, and his signature green jacket with a white line going through the 10 on the left pectoral, and two white lines encircled around his right arm sleeve.

Red lights flashed throughout the planes cargo hold, as his phone started ringing. He took his phone from his pocket and saw Tatsumaki calling him. He smirked as he sent her a text saying, 'He'll see her tonight.' He stuffed his phone into his pocket as he begun walking towards the cargo door as it soon started opening as he heard a voice erupt from the plane, "Legion, you're cleared for drop off." The pilot responded.

Legion smirked in acknowledgement as he ran and jumped from the plane. Legion quickly felt the wind whipping across his face as he descended towards the ground. He dived towards the ground as he closed his eyes when he flipped around his emerald eyes lit up in excitement, "IT'S HERO TIME!" He yelled as his left sleeve rolled up from the wind pressure. On his left wrist was a strange watch known as the Omnitrix.

He spun the dial as a hologram of one of his aliens appeared. He kept spinning the dial when he landed on the one he wanted. He slammed his hand onto the hologram as an emerald light engulfed the sky.

Legion was transformed into a lava molten man, with fire coursing throughout his body. His face erupted into flames as molten rock hardened around his face, sporting the Omnitrix badge in the middle of his chest, "HEATBLAST!" The Pryonite soon blasted the ground with flames as he was blasted back into the sky.

Sending the flames to his feet he was soon soaring through the air as he saw the tracks of the Saber and realized he was getting close to the village. Sending another burst of flames to his feet he soon shot forward at incredible speeds when he saw a giant silhouette walking on all fours.

Heatblast grinned as he shot his arm forward, flames surrounded the large beast as he flipped onto the dunes gaining the beasts attention, "Here kitty, kitty, kitty." The Saber growled at him as it paced back and forth looking for an opening.

The Pryonite's hands erupted with balls of flames, "Let's play a game. It's called dodged the fireballs." He grinned as the Saber pounced at him, Heatblast ducked the large beasts frontal assault. He threw a ball of flames at him earning a howl of pain from the beast.

The large Saber growled again as it got back onto his feet it soon spoke earning a gasp from Heatblast, "Man of fire, I'll make you regret crossing paths with the Leader of Sabers!"

"I thought the Sabers were extinct?" Heatblast replied as the Saber snarled at him and raced at him. He smirked as he opened his jaw wide as Heatblast caught his mouth with his large molten hands, "Trying to eat me? That's not very nice." He replied with a hint of sarcasm in his tone.

The Saber tried to urge forward to get a taste when it felt something burning it's body, "What are you burning?!" He shouted in anger.

"Oh, so you realized it?" He taunted as he jumped back holding the Sabers two large fangs in his hand, "Think I can keep these?"

The large beast went eye wild and a blitz of fury erupted from him, "I'LL KILL YOU!" The Saber's eyes turned red as it launched onto his back paws. It's skin turned a bizzare shade of orange, it grew blades out its elbows as it grew multiple muscles as the fangs that Heatblast burned off grew back.

Heatblast laughed as he wiped a flame tear from his eye, "Alright, I'll enlighten you. I'll also get serious." His mood switched from light hearted to serious, "I'll take any kind of challenge, but first it's time I get more comfortable. Time to go Ultimate." Heatblast tapped his badge and four prongs appeared out the sides of his badge. An emerald light blinded the large Saber.

Heatblast grew a large volcano out his back, with another two small volcanoes on both shoulders, and two more on both his forearms. His hands turned into claws, his knees grew a large sharpened piece of metal as his feet turned into claws as well. With a large volcano on his back, he sorta slouched forward. His face resembled the incarnation of death itself with flames around it. He wore the evolved Omnitrix badge on the volcano on his back, "ULTIMATE HEATBLAST!" The hyper-evolved Pryonite exclaimed, "Alright, let's play." His deep rocky voice replied.

"Bring it!" He yelled as he raced towards the walking Volcano who also rushed forward. The two beings collided in a test of strength. When the Saber pulled him in and kneed him in his stomach. Using the volcano on his back he blasted the Saber in his face burning him briely. Ultimate Heatblast then socked him in the face sending him flying onto his back. The sabers face quickly healed itself as they raced forward while trying to overpower the other, when Ultimate Heatblast's aura exploded sending the giant Saber back. The sand around the hyper-evolved Pryonite started turning into glass from the heat that was radiating from him.

"Let's turn up the heat!" His deathly face grinned as he summoned one large fireballs in his hands, "Catch!" He hurled the fireball at him, but the large Saber managed to dodge at the last second, but when the attack landed behind him he went wide eyed as it torched the sand behind him turning into glass. Ultimate Heatblast grinned as the volcano on his back erupted, "Let's end this!"

The large Saber growled in anger, "I couldn't agree more!" He raced towards the hyper-evolved Pryonite as the volcanoes on his back and arms started smoking. Once the large Saber was within his range he threw his arms forward as he let out a massive blast of a flamethrower. The Saber and some of the desert were caught up in the attack.

As the fire started dissipating the Saber was scorched to bones with the surrounding area becoming glass, "Guess the cats out the bag." He quipped as he tapped his badge and reverted back into Heatblast, he tapped it again reverting back to normal. Ben Tennyson or his hero name Legion the greatest hero in the world. He glanced around the barren desert till his phone started ringing. He quickly grabbed it and answered it, "Yeah? Alright, I'm on my way." He replied as he hung up and activated the Omnitrix by spinning the dial as he spun through it he quickly found his choice and slammed his hand onto the faceplate. An emerald light engulfed the area.

Ben was transformed into a blue velociraptor on wheels in a white and black jumpsuit. He had a cone shaped head, with a black and blue visor. The Omnitrix badge appeared in the middle of his chest, "XLR8!" The Kineceleran exclaimed as his visor slid down and he zoomed through the desert.

"I'm sure you're wondering what happened that led me to start working with the Hero Association, well it started six months ago."


Ben sat in his hospital bed staring at his television in surprise and shock, "What the fuck?!" He uttered as he was now the new rank one in the world, "This can't be real. Oh I know I'm dreaming and having a terrible nightmare and any moment I'll wake up." He closed his eyes and reopened them to find he was still there. He closed his eyes again and slapped himself a few times, "Okay, this isn't getting me anywhere." He sulked as his door opened revealing his best friend Genos and adopted grandfather Bang.

The blonde cyborg and the old martial artist came into the boys room, "Genos? Gramps? What are you guys doing here?" He questioned them as they took a seat next to his bed.

"Is it bad, that I want to see my grandson in the hospital?" Bang smiled at the boy.

"Besides we're here to see the new rank one." Genos said which bummed Ben out.

"Don't even mention it. I'm not proud of that." He replied a bit mad that they just assigned him a rank before even asking him.

"I cosigned it, since I took you under my wing and as your grandfather, you deserve to have the recognition you deserve after you fought tooth and nail to defeat the invaders." Bang explained sternly telling the boy he had a hand in making Ben the new S-Class Rank 1.

Genos and Bang watched the boy as he gazed at the window. It's true he risked his life for people that didn't know he existed. He loved being a hero it meant everything to him, he looked at the Omnitrix that was clamped onto his wrist. He remembered back to when he was ten and he first found the Omnitrix and was learning how to use it since then he's been trying his hardest to protect everyone even if it costed him his life. That's what a hero does, or at least what it means to him.

"Master, I know it's alot to take in, but think about it. You're by far the greatest hero to walk the Earth." Genos stated acknowledging the Omnitrix Wielder's powers.

"Alright, I might not know what to do with ya know being rank 1, but I guess I have no choice, but to fill the shoes that Blast left behind." He smiled as Bang and Genos smiled happily at Ben, "By the way, what did that smug bastard Amai Mask say when they decided to make me rank one?"

"Oh that's the best part." Genos smirked evilly as he grabbed Ben's hospital remote and changed the channel to a interview with Channel 5 and Amai Mask. Ben watched the TV as the interview started.

"Hello I'm Keiko Chiho from Channel 5 news and I'm joined by my guest Amai Mask a superhero/model/singer." The news reporter smiled as she held the paper with questions on it.

"Hello everyone." The ranked one A-class hero replied with a forced smiled on his face.

"Mr. Amai, how do you feel about Ben Tennyson aka Legion becoming the new S-Class Rank 1 Hero?" Keiko questioned as a scowl appeared on the model hero's face.

"Tennyson isn't anything special, he's a loser. He couldn't ever be the hero I am. He caused quite a scene when he was fighting their leader. I'd have ended him before he could even blink." Amai stated scoffing at the shape shifter.

"But if it wasn't for Legion, City A would still be in ruins and alot of people would remain dead or criticality injured. He healed them in the blink of an eye, rebuilt City A, and defeated nearly every single monster that has appeared inside that ship. Could you do what he can?" She questioned as Amai started getting frustrated with the news women.

"I can do it tenfold." He stated confidently.

"Then why weren't you participating with the other S-Class hero's during the invasion?" She asked as Amai scoffed at her question.

"I was promoting my album." He stated as he crossed his arms over his chest, "I didn't agree to even have him be placed in S-Class. He should have started from C-Class."

"But with his various transformations they all rival any of the other S-Class Heroes, even that night sky creature could rival Blast in power and he's stronger than you." She stated, "I believe they made the right decision placing him in the top 3 of the S-Class hero's."

"Yeah, you believe it. I doubt anyone else believes he should be in S-Class." Amai scoffed hating all the attention Ben was getting, "I also doubt Ben would be able to beat Blast."

"It's not just me, but multiple citizens in almost every City is with me. With a Hero like him in this world I doubt anyone from space would be a threat. Plus have you not been watching the clips of this monster. He recreated an entire City and healed the injured, not even Blast himself can do that." She rolled her eyes as she started getting annoyed at the A-Rank Hero, "Anyway that's all for today, I'm Keiko Chiho from Channel 5. If your listening Legion or Ben, I appreciate your bravery and your heroism keep up the good work, Mr. Number One."

Ben laughed at the annoyed hero, "Man, he's such a loser."

"Yeah, Amai has always been a boisterous individual, but I haven't really paid him any mind till now. How dare he call my grandson a loser." Bang was pissed as a wave of aura started leaking from the martial artist.

"Relax Gramps, he's nothing special. He's probably pissed because I'm stealing his Thunder." Ben laughed as he knew he had to stick it to the model superhero. Genos smiled as did Bang when a knock was heard on his door.

Ben, Genos, and Bang looked over at the door, "It's open." The door slid open revealing Tatsumaki, S-Class Rank-3, Yamato Kiyoshiro, the second head of the Hero Association, and Ren Takeo.

"Hello Benjamin or Legion whichever one you prefer." Yamato bowed lightly while he greeted the shape shifter, "I am Yamato Kiyoshiro, this is Ren Takeo. I'm sure you already know that since you were there at the S-Class meeting."

"Yeah, Gramps and Genos invited me." Ben replied as he gazed at the green haired girl who was a bit jittery from looking at the Omnitrix Wielder.

"Correct, it was your grandfather, Genos, Tatsumaki, and some of the other S-Class hero's who recommended us to place you as the new number 1." Takeo replied with a small smile on his face.

"What about the old number 1, Blast?" Ben asked curiously.

"We already talked to him, he said and I quote, 'If he was able to protect everyone while risking his life for people he doesn't know then he's a true hero and I completely agree with your decision.' He also told us he'd like to meet you soon." Yamato quoted words Blast relayed to them.

Ben, Genos, and even Tatsumaki went eye wide, "Blast really said that?" Genos replied a bit shocked.

"Yeah, a bit shocking right?" Yamato chuckled as Ben nodded, "Well aside from that, we'd like it if we were able to start working together from now on."

"I will on a few conditions."

"And those are?" Takeo asked.

"I want complete freedom. I don't want a leash wrapped around my neck and don't expect me to be at your beck and call if there is an enemy that other Class S hero's can deal with send them first, if not then call me, I'll take care of it." He reasoned not wanting to be some lap dog for the Association.

Yamato stroked his chin as he listened to the boys conditions as he smiled, "Glad to be working with you, Legion." He walked over and stuck out his hand.

"Likewise." He shook his hand as Yamato and Takeo left the boys room. Tatsumaki stood in her spot as they left, "Tatsu, are you alright?" He asked as the green haired psychic rushed forward and engulfed the boy in a massive hug.

"I'm glad you're ok." She screamed at him as he chuckled.

"I told you I'd be ok." He wrapped his arms around her waist causing the green psychic to blush lightly.

As the two were enjoying their company, "Ahem." Genos cleared his throat gaining both their attention as they quickly pulled apart, "Thank you. Anyway Master, are you really gonna work with the Hero Association?"

"Usually, I'd complain about them, but I feel like it's different now. It doesn't mean I trust them, but we'll see in the future, and if they plan on betraying me..." The three hero's went a bit wide eyed at the amount of aura that started leaking from him as he had a really dangerous look on his face, "I'll tear that entire building down."

Tatsumaki placed a hand on his shoulder making him relax, "Don't worry, Ben, we'll be right beside you." She grinned as he looked over at Bang and Genos who nodded in response.

"Thanks guys." He smiled brightly.


"And since then, I've been dispatched onto different missions all across the world." Ben finished narrating. He was currently in the Sahara Desert, after he got done wrapping up the Saber. He was heading back to Japan.

He made it towards the edge of Africa as he launched into the air and tapped his badge. He was transformed into a red pterodactyl with a jetpack and glider on his back. In a black and green uniform, green gloves on his hands, silver belt around his waist. The Omnitrix badge appeared on his left shoulder, "ASTRODACTYL!" The pterodactyl like alien screeched. The wings on his back shot outwards and the jetpack ignited. Sending Astrodactyl flying across the ocean.

He was flying for a few minutes before the Omnitrix started beeping gaining the boys attention. He looked at it as it came to life, "Unknown occupants have been spotted in 43.8791 N, 103.4591 W, South Dakota, United States." The coordinates made Astrodactyl raise his eyebrow in curiosity. He immediately put the breaks on his current path.

"South Dakota? Why does that sound so familiar." He questioned as the true reason why he kept thinking of that location eluded him.

"Omnitrix set coordinates to South Dakota, 43.8791 N, 103.4591 W." The pterodactyl alien screeched as it said, "Coordinates set." Astrodactyl immediately turned around as he flew at his fastest.


In City A, a large building stood tall and proud. It was the new redesigned Hero Association building. It was recolored green and black with a special plumber insignia on the tower. Grey Matter, Brainstorm, and Lodestar had spent almost four months redesigning and had used the aliens ship to make it more durable and stronger against attacks.

Inside the building, looked to be inhabited by Upgrade one of Ben's aliens. The technology looked more advanced thanks to Grey Matter and Brainstorm. Ren and Yamato smiled at the building.

"That boy is amazing." Ren smirked as he loved the new headquarters.

"Indeed, I can't believe we almosted asked Metal Knight to make our new Headquarters. The way Grey Matter and Brainstorm made the new designs had blew my mind then had Lodestar quickly dismantled that alien ship and make out new base far more advanced than Metal Knight ever could." Yamato replied.

"Sir, Legion has taken care of the Saber in the Sahara Desert." The women spoke from her place in front of multiple computer screens.

"Good, is he heading back?" Ren asked.

"No it appears he's going somewhere else." She responded as she tried to lock onto his coordinates.

"Find out why." Yamato replied.

"Yes sir." She replied as the doors to the room opened revealing three familiar faces. Genos, Bang, and Tatsumaki.

"It's you three, what's wrong?" Ren asked.

"Nothing, wondering where Ben is? He's usually back by now." Bang stated sternly.

"From what we heard we lost communications with him, after he defeated the Saber in the Sahara. It seems he's heading somewhere else at and incredible speed. That's it hard to track him. " Yamato stated as he pulled out a cigarette and lighted it.

"I thought you quit." Ren replied.

"Shut up." He said as he took a puff from it.


Bellwood, 2013

One Year since Ben's disappearance

A man wore a silver helmet with a purple visor that blocked all view of his face, leaving only two glowing purple eyes visible. He retained the black bodysuit, but had silver boots, gauntlets, and a chestplate instead; a purple cape to replace his coat. He sat in his throne in his ship as the world's greatest hero disappeared without a trace until now.

"Sire! We've got a trace!" One of his henchman shouted as this caused the man to grin widely.

"Put it up on the screen!" He shouted as the screen in his throne room lighted up. He gazed at the boys alternate Earth, "Interesting. Before we head after the boy it's about time I gain more Allies."

He tapped his gauntlet, "I'll be back soon." He slammed his hand onto the gauntlet and disappeared. To where no one knows to when let's find out.


Four Years Ago

The man landed in a futuristic base as he remembered it to be Future Ben Tennyson's base. Gwen was kidnapped by the older version of herself and forced Ben to follow after them where he met his future self. The man smirked at himself as he knew who he was looking for.

He waited until the base started shaking and knew it was their battle going on. When a large figure was launched upwards through the floor. He slammed onto the ground and got up. It was a man's head inside a dome with purple liquid inside. He had gold technological wrapped around the dome, with a gorilla's body, with gold canisters on his forearms. This was the future Doctor Aloysius James Animo. He is a doctor that studies and control animals, the first Member of his new team he was putting together.

The man quickly raced forward and grabbed hold of the Gorillafied Animo and in a purple flash of light the man and gorilla Animo were gone. When two figures launched their the hole caused by Animo. It was a futuristic Diamondhead and the past Four Arms.

"Where'd Animo go?" Four Arms asked.

"I don't know, let's head to the lab and see what he stole." The future Diamondhead replied as they both went through the hole caused by Animo.


Present Day

The man and Animo arrived back into the present as the Gorillafied doctor grabbed the time traveler and flung him into the wall earning a yell from the time traveler, "Who are you?!" He yelled.

"A friend. I got you out of that sticky situation you found yourself in against that cursed past Ben Tennyson and Future Ben Tennyson." He answered as he got back onto his feet.

Doctor Animo glared and stared at the man, "I didn't need your help! I had them right where I wanted them." He shouted proudly even tho he was losing.

"I'm putting together a team, and need your help if I'm gonna be able to destroy Ben Tennyson once and for all." The man answered as Animo looked at him in interest.

"A team you say? Who are these members you've got in mind?" Animo asked curiously with an evil smile on his face.

"You'll meet them, if you decide to join. Interested?" He asked.

"If it's to destroy that cursed Shape shifter, I guess I'll offer my services to your cause." He stated, "If you plan on betraying me, I'll make you regret it."

"Never dream of it." The man crackled as he looked at his gauntlet, "Stay here, I'll gather the rest of the team." Animo nodded as he slammed his hand onto the gauntlet and vanished in a purple flash.


Three Years Ago

The man arrived in Bellwood on top of a building, he wrapped his arms behind his back as he gazed around, "This should be the right year." He looked around as he then caught sight of numerous drones surrounding a familiar Pryonite, "Bingo!" He watched as Heatblast roasted every single drone. Until a large spiked orb approached.

Almost mowing down the Omnitrix Wielder, Heatblast dodged the orb as it moved a safe distance from him and split into a large pill. With a metal hatch in the middle. The hatch opened to reveal a humanoid creature with a face resembling that of an octopus. He has tentacles dangling in the front of his face, like a beard. His skin is pale-green with yellowish spots on his face and tentacles. He doesn't have a nose and a visible ear. He has red eyes. He had become much more burly than before. He now had a mask covering his mouth, attached to the armor, and new shoulder and leg pads. He also had metallic gloves with small fingers as well as reddish brown cylinder-like objects piercing his arms, giving him much stronger and more muscular limbs. His tentacles are now much longer. He has 6 tentacles in front and 2 behind. This is Vilgax who has traveled from his home planet to obtain the Omnitrix, but has been bested by Ben Tennyson every single time.

"At last we meet, the being that has caused me so much trouble." His raspy voice echoed out.

"Who are you?" Past Heatblast stated as he was pinned to the wall, by blue energy whips.

"I am Vilgax, I have come for the Omnitrix!" He bellowed as he declared he wanted the Omnitrix.

"Ah, I'm guessing your not with the good guys?" He replied with sarcasm. He quickly started heating up which made the metal hatchs start melting around him, he quickly freed himself and launched at Vilgax. Throwing punches at him which did nothing to him.

Vilgax towered over the Pryonite as he grabbed him by his body and flung through an entire buildings. Heatblast was sent through seven buildings till he came to a stop. He bursted from the debris, "Ok, this guy is really tough." In one single leap, he launched into the air and landed a few meters away from the Pryonite, "Gotta slow him down." Overcharging himself he blasted at the ground causing it to melt insane fast. The tar didn't stop Vilgax as he tried to walk through it falling onto his hands and knees.

Smirking proudly Heatblast started walking towards him when a beige RV came driving towards them. Vilgax finally stood tall as Heatblast smiled cockly, "Not so tough when you can't move, are you?" The RV came to an abrupt stop in front of the two aliens.

The door to the Rust Bucket swung open revealing a girl with orange hair, green eyes, wearing a blue shirt with a cat on it, and white pants, "Ben, grandpa says to get in, now!"

"What are you talking about! I'm just about to kick alien butt!" He shouted as the Omnitrix started flashing red gaining both the little girl and Ben's attention when in a flash of Red, the Omnitrix timed out. Ben looked at himself as the old man in the drivers seat yelled at him.

"GET IN THE RV, NOW BENJAMIN!" He shouted, Ben went eye wide as he now jumped into the RV as he closed the door and soon the old man drove off leaving the armorfied octopus behind.

The man smirked as he tapped his gauntlet and both him and Vilgax disappeared in a purple flash. Sending them both to the present.

The man landed in his throne room with Animo and a now furious Vilgax, "WHAT DID YOU DO?! I WAS ABOUT TO GET MY HANDS ON THE OMNITRIX! BEFORE YOU INTERFERED!" He yelled as he grabbed hold of the man by the throat.

"If you allow me to explain! I'll tell you!" He choked out as Vilgax sneered at him as he dropped the man onto the ground as he glared at him and the Gorillafied Animo.

"Make it quick, human, before I kill you." He sneered as he crossed his arms in annoyance.

The man rubbed his throat, "I'm putting together a team in order to obtain the Omnitrix and destroy the person who's wielding it. I need your help."

"Why should I help you?!" Vilgax glared at them getting annoyed even more.

"Because if you help me, I'll give you the Omnitrix." He smirked inside his mask as Vilgax squinted his eyes in annoyance.

"You better not be lying human, if you are. I'll kill you in the slowest way possible." He glared even more intensely at him.

"Glad to have you on board. I'll go assemble the rest of the team." He stated as he slammed his hand onto the gauntlet and vanished in a purple flash.


Four Years Ago

The man arrived behind a large purple tent that looked to resemble a circus. He looked around as he saw the three stooges Acid Breath, Thumbskull, and Frightwig, "The Circus Freaks, now where's Zombozo?" He watched as Wildmutt appeared and fought against the three freaks.

While Wildmutt fough against them he walked towards the giant tent to avoid the Ghostfreak and Zombozo fight. He saw a giant machine with trapped souls inside. He gazed around as he heard a voice, "Ohhh, a new contender. What brings you to my humble aboad." The voice echoed out.

"I have a proposition for you if you're ready to listen." He called out as the voice cackled evilly as he started lowering himself to the ground. The man gazed at him, "Zombozo the vampiric clown, there's a boy who's gonna come in here and he's gonna show you a really scary trick. Which will make you explode."

"Interesting. What does that have to do with you?" The vampire clown asked.

"I want to destroy that boy, while taking over the world." He said as Zombozo raised an eyebrow at his claim.

"Interesting, but what can you offer me?" He questioned the time traveler.

He smirked evilly, "All the souls you want."

Zombozo went a bit eye wide at him and smirked evilly, "What are we waiting for?! Let's go!" He laughed evilly as the man grinned evilly and smacked his gauntlet and the two beings vanished in a purple flash. As the ten year old Ben Tennyson came in and realized Zombozo was gone.

The two beings arrived in the man's throne room as Zombozo gazed around he noticed a fuming Vilgax, and Animo who seemed to be waiting for the remaining members of this team, "Welcome Zombozo meet Vilgax and Animo."

"Greetings coharts." Zombozo greeted as Vilgax shrugged him off as he was more concerned with gaining the Omnitrix.

"Ignore Mr. Brood over there, I'm Doctor Animo!" He shouted as Zombozo bowed to him as he took off his hat.

"Alright, I've got six more members to retrieve, don't kill each other until I've return." He stated as he tapped his gauntlet and vanished in a purple flash.


Earth Prime

Prime Ben's Earth

Year-2016

The man arrived in a eerily dimension surrounded by an intense feeling he gazed around as he was surrounded by Celestialsapiens. He smirked, "Two birds one stone." He watched as Kevin Levin absorbed the Ultimatrix and a white light blinded them.

He looked over towards the Ultimate Aggregor who was a mix of the five aliens that he hunted down. Ultimate Aggregor's mixed body parts were comprised of the hands and lower body of Bivalvan, the front torso of Galapagus (though with a darker color), the unarmored back and arms of Andreas, P'andor's faceplate on his neck, and seal on his chest, and a head resembling that of Ra'ad. As he was about to grab hold of the infant Celestialsapien when a clawed hand grabbed hold of him. He looked up at the voice and went wide eyed.

"Surprised? You shouldn't be." He replied as he then punched the mixed hybrid away.

Kevin was composed of a larger pool of aliens than his earlier mutations, with multiple parts of his body now being combinations of multiple aliens. His face mostly resembled Jetray's but had Kevin's hair, a patch on his right eye consisting of Swampfire's skin and Humungousaur's eyebrow, and a jaw belonging to Humungousaur that splits like Ultimate Spidermonkey. His torso came from Humungousaur but had a backside colored like Jetray. Draped over it was the cloak/set of wings of Big Chill. His right arm mostly resembled Diamondhead's, but with two magenta crystals on his shoulder resembling Chromastone's and a claw resembling Lodestar's. His left arm mostly resembled Swampfire's, but with a metal shoulder spike belonging to Lodestar and a wrist claw belonging to Rath. His right foot resembled Jetray's, while his left foot resembled Rath's. He also had Humungousaur's tail, two of Brainstorm's legs in place of a secondary left arm, one of Spidermonkey's arms as a secondary right arm, and portholes on both his Swampfire-like hand and Lodestar-like claw. Kevin wore his pants, albeit with tears at the edge of the legs.

Before the fight could continue, the man tapped his gauntlet and all three him, Ultimate Aggregor, and Ultimate Kevin vanished in a purple flash. The man took them from Ben Prime's Earth to the new Earth where Ben had vanished from. The time walker and the two ultimate osmosian's landed in the throne room of the ship.

The two ultimate osmosian's looked around in confusion, "You two must be confused on what just happened." They turned towards the man approaching them, "I need your help, both of you."

Ultimate Kevin sneered, "Why would I help you or even work with this psychopath?!" He bellowed angrily.

"The boy is right, I have no interest in helping you. I want that Celestialsapien child and then the world will be mine." Ultimate Aggregor stated.

"You won't be getting your hands on that child, Aggregor." Kevin glared at the ultimate being in front of him.

"You really believe you can stop me, Levin?" Aggregor questioned with a glare.

"Let's find out." He yelled as the two beings were getting ready to rush the other when the man froze them, "What's happening? I can't move!"

"What did you do?!" Aggregor glared at the man in question as he came into view.

"I simply stopped this feud from escalating. Gentlemen, relax. I can offer you both something you desire." He offered gaining the ultimate osmosian's attention. He looked over at Aggregor, "I can offer you power beyond your wildest dreams."

"Interesting, more than that Celestialsapien child?" Aggregor questioned.

"Of course."

"Alright, human. I'll work with you, but don't mistake my kindness for weakness." Aggregor assorted as The man nodded and smiled.

"Good to have you on board." He then turned towards Kevin, "And you I can offer the greatest gift of all. The head of Ben Tennyson, you're greatest adversary, the man who's beaten you so many times and always gloated about it." Kevin's anger towards Aggregor started subsiding when he thought about the man who's defeated him every single time they fought.

"Tennyson!" He yelled in anger, "Fine, I'll offer my help to you, but once Tennyson is dead, you're sending me back."

"Fine by me, I'm sure you know Animo." Animo stepped out of the shadows in a gorilla body, "Zombozo." The Vampiric clown also stepped forward with a wide sinister grin on his face, "And Vilgax." Vilgax came forward with a sneer on his face.

"Powerful Allies you've acquired." Aggregor stated as he eyed everyone of them, "Impressive."

"You got Vilgax to work with you?" Kevin questioned as he unfroze the two ultimate osmosian's.

"Yes, once we get the Omnitrix off of Tennyson it's his. And Tennyson is ours for the taking." The man replied as Kevin grinned sinisterly.

"Good."

"Alright, I've got four more members to recruit, don't destroy my base or else you'll face my wrath." He glared as he tapped his gauntlet and vanished in a purple flash.


Earth Prime

Prime Ben's Earth

Year-2018

In a purple flash, the cloak man gazed around and smirked, "He should be coming right..." As he trailed off a man was sent flying into a dozen trees with a large beast that transformed into a mix of a dog and dinosaur.

Khyber the hunter and Zed the Nemetrix Wielder.

Khyber has a black suit covering his upper body with a red stripe in the middle and grey pants. He has grey gloves and a grey belt, as well as black boots with grey soles. He wears bones as ornamentation over his clothes, which consists of a ribcage on his chest, a tail bone on his right shoulder, a horned animal skull on his left shoulder, ribs covering the back of his black suit and boots, and claws on his shoes.

Zed is a dark blue creature that appears to be a cross between a dog and a dinosaur. She has red eyes, blue-gray spike-like hair running down from her collar that held the Nemetrix to the tip of her tail, and black lines on her neck and legs.

Khyber growled as he got back up as he grabbed a sword from his back as it ignited. Zed growled as he transformed into a large, segmented purple and gray body and a red head resembling that of a Carnotaurus or a Tyrannosaurus with a horn on her forehead. Tyrannopede has four legs and six small arms with two clawed fingers on them. Tyrannopede wears a red spiked collar with the Nemetrix on it.

Trynnopede roared loudly as sixteen year old Earth Prime Ben Tennyson came into view with a smirk on his face, "Khyber, buddy, I'm serious stop following me."

"I'll stop following you when you relinquish hold of the Omnitrix." Khyber growled as he ordered Trynnopede to charge when the Kaosseffexx Ultimasauria rushed forward.

Ben was quicker and slammed his hand onto the Omnitrix and was transformed into tall figure, who has a black body with one green eye in the middle of his head, two antennae, a tail with round plugs on their tips, four-fingered hands, and feet with only two front toes. His chest is colored green, with the Omnitrix badge resting on his chest, "FEEDBACK!" The Conductoid yelled as the Trynnopede collided with the Conductoid.

Feedback flipped into the air as electricity blasted from his hands and hit the Kaosseffexx Ultimasauria head on. With the surge of electricity coursing through his body he was blasted backwards landing behind Khyber. He reverted back to normal and slowly got up when Khyber raced forward with his sword raised. Once he was within reach of the Conductoid, he and Zed vanished in a purple flash. Feedback raised an eyebrow as he looked around for the hunter and the predator dog.

"Where'd they go?" He asked in confusion.

In the distance, Khyber and Zed reappeared ontop of a building in Bellwood. Khyber sliced the buildings roof cracking it. He growled in frustration as he looked around, "Who dares interfere in my battle?!" He yelled out as the man came forward in a purple blur.

"I did." He spoke in a low tone, "Khyber, I need your help."

"Why should I help you, let alone trust you?!" He growled in annoyance as he gripped his sword tightly. As Zed stood by his owners side.

"Because, like you I also have a deep hatred for Ben Tennyson. I'm putting together a team, so we can get rid of the alien hero once and for all." The man spoke gaining Khyber's interest.

"Your planing to kill Tennyson? I don't believe it. He's bested everyone, Vilgax, Albedo, Maltraunt. It's impossible to beat him." Khyber spoke narrowing his eyes at the man who grinned.

"Maybe so, but if all said villains formed a team against him, not even the great Ben Tennyson would be able to win." He spoke confidently as Khyber growled in annoyance.

"Fine, we'll try and get along. Me and Zed are under your leadership till Ben Tennyson is out the picture." Khyber negotiated as the man smirked eagerly.

"Wait, here there's someone else in this universe I need before we head out." He spoke as he vanished in a purple flash.

In a warehouse, in Bellwood, surrounded by empty chilli fry bowls and smoothies sat a boy that looked exactly like Ben Tennyson. Scratch that he was Ben Tennyson, but he had snow white hair, red eyes, black shirt, dark blue jeans, black and white converses. He sat at his desk fiddling with a gauntlet. He took hand fulls of chilli fries from a bowl to his right as he stuffed it into his mouth, "Curse these highly addictive chilli fries. Once I get this Omnitrix operating Ben Tennyson won't know who hit him."

He grabbed his screw driver as he drilled in the final piece to his Ultimatrix. His eyes went wide as the faceplate glowed red signaling the Ultimatrix was ready to be used, "SUCCESS! Watch out Tennyson, I'm coming for you!" He slid the gauntlet onto his left arm, as he grabbed his jacket that was placed on his chair. He quickly put the red leather jacket on as it looked exactly like Ben's jacket. It had a black line go through the ten on the left pectoral and two black lines on the right sleeve.

"Albedo." The voice relayed the name as the snow white doppelganger turned around, "Your services have been required."

"Who are you? Where did you come from?!" Albedo asked a bit shocked on how he appeared out of nowhere.

"Don't worry about who I am, all you have to worry about is do you want revenge on Ben Tennyson?" The man questioned as Albedo got over his shock and then his mood shifted into hatred.

"Do I want revenge on Tennyson? Is the sky blue? OF COURSE I DO! It's his fault I'm trapped in this hideous body. Now that I've got my new Ultimatrix working I'm gonna go find him and kill him myself." Albedo gritted his teeth in anger as he tightened his fist angrily.

"Well, I can be of services to you. I'm putting together a team, and require your power." He replied as Albedo narrowed his eyes at him.

"What's this team supposed to do? Go shopping like a couple of losers?!" He quipped as he sneered at himself, "Ugh, Tennyson and his stupid quips."

The man chuckled menacingly, "No, we're gonna hunt down and kill Ben Tennyson once and for all."

Now this caught Albedo's attention, "Kill Ben Tennyson, you say? Now that's very interesting. Once I get his Omnitrix I can finally revert back to normal."

"What do you say?" He asked knowing that Albedo wasn't gonna say no to his offer.

"Alright, I'm in." He stated as he smirked eagerly his team missing two more members. He tapped his gauntlet and him and Albedo teleported back to the building he left Khyber and Zed.

"You left to get Albedo?" Khyber growled as Albedo scoffed.

"I could be saying the same thing, Khyber." He glared as the man clapped his hands toward and broke the two of their feud.

"Gentlemen, relax from here on out you're teammates after Ben Tennyson is dead, you can go back to hating each other." He replied as both the doppelganger and the hunter continued glaring at each other before agreeing to playing nice.

The masked man tapped his gauntlet and the four beings teleported back to his ship on his Earth. As the five members were waiting. Albedo, Khyber, and Zed looked at the members who looked at each other.

"You brought this freak here!" Albedo shouted pointing to Kevin.

"Who you calling a freak, you Ben Tennyson wannabe." Kevin shot back as Albedo reached for his Ultimatrix, "Ah, I see you got your knock off Ultimatrix working again, but you seem to forget, I have all the power of the Ultimatrix and more."

Albedo gritted his teeth, "Just you wait, after I get done with Tennyson your next."

"I'll be waiting, you knock off reject." Kevin quipped making Albedo fume in anger.

"Everyone calm down. I have two more members to acquire and once their here we can begin." He replied as he tapped his gauntlet and vanished into a purple flash.


Four Years Ago

The masked man appeared in a desert, he looked around as gazed around for the alien bounty hunter, "If my memory is correct, he should be appearing right about now." He said as a man was thrown into a building followed by a gold crab, "Right on time." He quipped.

He has purple pads covering his central joints, a belt, and four central lines on his helmet to provide outlines for his face, which are his eyes and mouth. When his black and pink mask is broken, it reveals an ugly, mutant, gray-yellow creature with pink and gray robotic eyes and four arms. His feet are hooved.

The robot resembled a fiddler crab with a goldish brown-colored armor, a sideways mouth, four scythe-like legs and a large, powerful pincer for a left hand. Within the pincer was a power blaster combined with a chemical sprayer. When he goes underground by spinning his legs, he retracts his head down, making his neck disappear. He had orange lines running over his body and his eyes had the same color as the highlights of his pincer. This was Kraab and SixSix alien bounty hunters hired to obtain the Omnitrix.

The man smirked as he snapped his fingers and everything froze. He walked over to the downed bounty hunters and only grabbed SixSix and vanished with him and everything resumed. They teleported a distance away from the fight as SixSix pushed the man away.

The man knew he wouldn't be able to understand SixSix pushed his translater in his mask as he spoke, "Why are you interfering in my hunt for the Omnitrix?!" He immediately pulled out his weapons and aimed them at him.

"My friend, if you work for me I can ensure you the Omnitrix." The man spoke in the same language earning the Mutant Sotoraggian's interest.

"Why should I help you?" SixSix responded cautiously.

"Money." He simply stated as SixSix put his weapons away and nodded, "Good to have you on board." He tapped his gauntlet and the two beings vanished in a purple blur. They reappeared on the man's ship as the others looked in as the two beings reappeared on the ship.

"You brought SixSix?" Khyber growled as the mutant Sotoraggian's was brought on aboard.

"Yes, we're gonna need his help. Now once I bring my final recruit we will mobilize on Tennyson." He stated as they nodded except Vilgax who sneered.

"Hurry up, human. I want the Omnitrix!" He shouted angrily.

"Wait, a little longer my friend, I'll be back in a minute." He replied as he tapped his gauntlet and vanished in a purple flash.


Two Years Ago

He appeared in a purple flash, as he gazed around, "It appears I've found our last Member." He walked down the halls of the Forever Knights Manor and saw the pictures of Driscoll in various poses till the masked man scoffed at them, "Some Knight." He kept looking for the man in question who was nowhere to be seen, "Where is he?"

When the man in question was loading himself into a giant suit of armor. Driscoll used a power suit that gave him enhanced strength, durability and could project energy blasts from his gloves. He placed the helmet onto his head, "Driscoll." The man called out.

"My name isn't Driscoll anymore. I am the Forever King." He exclaimed as he turned towards the man in question, "What do you want?" He questioned the masked man.

"I require your services, for a team I'm putting together." He replied as the knight king glared at him.

"Why should I help you?" He demanded his anger growing.

"For a plumber, who's been caught stealing technology left go then formed the forever knights who still steal technology. I know you're hunting down the Tennyson family in order to acquire the Sub-Energy particular hiding in Mount Rushmore's base." He explained Driscoll's life shocking the Forever King.

"How did you know that?!" He shouted in anger as his helmet's started lighting up.

"Because if you join me in destroying Ben Tennyson. You can have this." His hand opened up revealing a yellow orb floating five meters above his palm.

Inside his suit, Driscoll went wide eyed, "How'd you get that?!" He asked in shock.

"Don't worry about it. You join me, you can have it to destroy the Omnitrix Wielder." The masked man smirked inside his mask.

Driscoll narrowed his eyes as then a thought occurred inside his head, 'Betray him and steal the orb.' He grinned sinisterly when the masked man smirked.

"Don't even think about it."

"What?" He asked in shock.

"You're betrayal won't go unnoticed, so don't even think about it." He glared as the king groaned.

"Fine, I won't betray you. I'll offer my services in exchange for the Sub-Energy." He countered as the masked man nodded his head and tossed it to him. The chest plate of the forever King opened and in place the Sub-Energy was placed inside and his suit charged up like a battery, "This is the power I was seeking, let's go destroy Tennyson."

"Let's go." He smirked as he tapped his gauntlet and they both disappeared then quickly reappearing on the ship gaining the audience of the other members, "Gentlemen, meet the Forever King. Now that everyone is here shall we head out." He gazed at Driscoll in his Forever King armor, SixSix, Albedo, Ultimate Kevin, Ultimate Aggregor, Vilgax, Future Animo, Khyber and his dog Zed, and finally Zombozo.

"You never gave us your name." Aggregor stated as he narrowed his eyes at the masked man who assembled the greatest league of villains ever.

"You can call me, Eon." The time walker responded as he tapped his gauntlet and his ship with everything and everyone onboard floated into the universe that Ben had been living on.


Astrodactyl had been flying insanely fast when he realized he was getting close to his destination, "We'll be arriving in twenty minutes." The Omnitrix spoke as the alien pterodactyl looked downwards as he passed through various buildings and wildlife. No idea at what he was about to encounter.

He was getting closer to Mount Rushmore as he landed onto the ground and saw the four President's faces engraved on the mountain, he looked around for a few moments before speaking, "The Omnitrix said unknown occupants had been here, so were are they?"

He was getting skeptical when a laser blasted the pterodactyl in the back slinging him forward. He looked up at where the laser came from and went wide eyed. Standing on a cliff above him were ten figures. He heard a beeping sound and soon an emerald flash gained the audience's attention as they gazed at the so called hero.

"What the hell?!" Ben yelled at the Omnitrix before gazing back at the ten members standing before him.

"Sorry, for the wait Tennyson, but I had to put together a little team." A voice called out as a man wore a silver helmet with a purple visor that blocked all view of his face, leaving only two glowing purple eyes visible. He retained the black bodysuit, but had silver boots, gauntlets, and a chestplate instead; a purple cape to replace his coat. He walked forward and threw his arms openly, "Benjamin Tennyson, Meet the Ultimate Negative Ten."

"Negative Ten?" He went wide eyed as he remembered the group of villains that assembled when he was kid after Sub-Energy or just wanted revenge on him. But he looked up and saw this team was different from when he was a kid.

"Yes, the first Negative Ten wasn't as strong as this one is. Why don't we meet some old friends of ours." He pointed to futuristic gorillafied Animo, "I believe you know Dr. Animo." Standing next to Animo was a clown in a top hat and suit with a red nose, "Zombozo." Standing next to him was a giant mechanized octopus, "Vilgax." Next to Vilgax was an alien bounty in a purple and black suit, "SixSix." Then was the next bounty hunter with a dark blue dog, "Khyber and Zed." Next to them was an ultimate osmosian, "Ultimate Aggregor." Next to him was his doppelganger in red, "Albedo." Next to him was another ultimate osmosian, "Ultimate Kevin." Next to him was the armorfied knight, "The Forever King, and lastly me, Eon."

Ben gazed at each one of them and could tell each one of them were powerful in their own right.

"Once again, Ben Tennyson, Meet the group of Villains who will end you forever. THE ULTIMATE NEGATIVE TEN!" He announced before smiling menacingly, "Kill him."
