So this is my first Teen Titans fanfic, and I'm going to apologise in advance if anything I write is too out of character, since I haven't watched the show in a while. So without further ado, here's chapter 1 and I hope you like it.

Disclaimer: I don't own Teen Titans.

"Titans, Go!"

The doors to the bank burst open as the five responded to the standard command. The Titans took up battle positions, surveying the inside to see what emergency they were responding to.

Looking back at them was a group of four, all of whom seemed surprised to see the Titans. "You said we had five more minutes, you lying crud-muncher!" The smallest one snapped, activating his wings and flying into the face of their leader.

"I did nothing of the sort you arrogant brat," He snapped back. "Now quit whining and let's deal with them, or this is the last job I hire you for."

"I don't think so Light," One Titan told him coldly, her voice rough. "I think you need a reminder of our last encounter."

"Take it easy Raven. We need to hand them over to the police intact." The lead Titan reminded the purple cloaked Titan.

"I don't think we need to worry about that Robin. Raven's got great self-control," The green Titan defended her.

"He knows that Beast Boy." The tall armored reminded him. ""Calm down little bud. Robin's not insulting her."

"Perhaps you could assist me in sealing the door Cyborg instead of arguing with our green companion?" A light soprano voice asked. "Robin? Should we perhaps be defeating them rather than debating?"

"You're right Starfire." Robin admitted. He snapped out his long bo staff, and gave the quick set of orders. "Raven, stand guard over Cyborg and Starfire. Beast Boy, with me. Let's go!"

"Not so fast Titans!" Growled Dr. Light. Raising his arms, he sent out two bright flashes followed by a laser barrage.

"Look out!" Robin snapped, rolling to the side as soon as Light raised his arms.

"Too predictable Robin." Came a laugh from the side and Robin snarled.

"Red X." He ground out. The other laughed, his face concealed by his hood, still laughing as he ducked under a swing from Robin and returning a blow of his own. With those blows exchanged the two took to their battle, leaving Beast Boy with the rest of the villains.

Beast Boy, still blinking, switched into a bat and let out a quick screech, pinpointing where everyone was in the room. He took off, flying above Dr. Light to try and distract him while aiming for the small figure flying around after him.

"Get back here snot-face!" The little figure demanded.

"Dude, grow up. Who calls anyone snot-face out of kindergarten?" Beast Boy demanded, shifting from bat to pterodactyl. "I mean, come on Gizmo. Surely someone as smart as you has a better insult than that."

"Don't need one to be smarter than you crud-muncher." Gizmo sneered. "Least I'm smart enough not to let Mammoth grab me."

Too late Beast Boy felt a massive hand tighten around his ankle. With a startled shriek, he felt himself pulled down from his flight path, with the hulking Mammoth gripping him by the throat. "I could use a massive drumstick." Mammoth growled.

"How about I cook him first for you?" Gizmo chortled, pushing a button on his pack to release a long arm emitting sparks from the end.

"How about you put my little buddy down before I make you?" Came a loud voice. Gizmo shot around, his robotic arm still extended towards Cyborg, who had leveled his sonic cannon at him. Reaching out, he snapped the sparking arm before shooting the boy genius across the room. "Boo-yah!"

Mammoth watched Gizmo fly across the room and held Beast Boy at arm's length leveling a glare at Cyborg. "One step closer and I snap his neck. And if you come near me with that little toy, he'll be dead."

Cyborg stared down Mammoth, before giving a start as the huge villain was suddenly surrounded in a black aura and slammed into the far wall, with Beast Boy still hovering in place. "You aren't killing my friends today." Raven told him coldly.

Mammoth struggled to stand, only for Cyborg to catch him in the face with a sonic blast. Before the man could stand, Cyborg ran up and slammed the villain into the ground with a double fisted punch. Beast Boy, having been lowered to the ground by Raven, reverted to human before falling to his knees. "Thanks Rae," He said weakly. "Glad my distraction worked."

"Distraction?" Raven asked dryly as she helped him to his feet.

"Yeah. I didn't want those three rushing you. I figured if I could keep Gizmo and Mammoth busy, Light would rush you and you'd take him out. Then you and Cy would help me while Star helped Robin." Beast Boy let out a hoarse cough. "Shouldn't have waited that long though. Next time I go sea anemone."

Raven let out a low chuckle. "Good plan. Now, let's go snag Red X before he teleports away."

Beast Boy nodded, shifting into a massive tiger. "Bet I'll get there before you." He growled.

Raven shook her head. "No bed." She told him, floating forward. "Azurath, Metryon, Zinthos!" She ordered, her power surrounding two ATM machines, which she pitched at Red X.

Looking up, the thief's eyes widened as he flipped over the first machine and ducked under the second. "Bloody hell," The villain muttered. "That was lethal fire!"

"I figured you'd dodge it." Raven told him calmly. "By the way, shouldn't you be worried about the others, instead of whining to me?"

Before he could reply, Robin's boot connected with his back, knocking him flying. Starfire's glowing hands released two bright green bolts of light, knocking Red X even further before Cyborg shot him in the stomach. It didn't do much damage beyond sending a shower of sparks everywhere. "Damn it." He cursed. He sat up and shook a fist at Cyborg. "You're gonna pay for that!"

Suddenly he heard a low growl in his ear and he slowly turned his head to see a green tiger baring its teeth. Before he could move Beast Boy had him pinned from behind, one set of claws on the back of his neck. Robin stepped forward cautiously. "I say we've got two choices X. I can cuff you and chain you to the table there or Beast Boy can sit on you 'til the cops arrive. It's your choice right now but I'll warn you; B.B.'s a little twitchy right now."

Beast Boy let out a combination of throaty chuckle and growl. Red X looked up at the Titans and flinched as claws warningly touched his skin. "I'll take the cuffs." He said gruffly.

"Smart choice." Robin said. He snapped the cuffs on Red X and nodded to Beast Boy. Beast Boy shifted into an anaconda and wrapped himself around the thief. "Start walking. You won't get far if you try and run."

Before Red X could reply, a piercing scream shook the room. The Titans spun around, looking for the source and found it in Gizmo. The boy, his mechanical backpack destroyed was running from some sort of creature and screaming at the top of his lungs. Dr. Light was on the ground, a different creature attacking him while a third was wrestling with Mammoth, while a pack of each creature seemed to be materializing from the walls.

"Titans, go!" Robin ordered. "Beast Box, release Red X. He can fend for himself or hide but we aren't compromising you for this fight."

"Screw this, I'm getting out of here!" Red X snapped. Beast Boy released his coils and shifted back to human, so Robin threw a small disk that snapped onto Red X's belt. There was a sudden burst of sparks and Red X let out a yelp.

"No you're not." Robin said coldly. "You don't have a teleporter. Stay out of our way."

"Robin, I fear we have a problem!" Starfire called over anxiously. She was firing off her starbolts at the creatures and was only succeeding in being chased. One grabbed her by the leg and brought her down to ground level. She punched it in the face and drew back her hand, wincing. "I cannot hurt these things!"

"Me either!" Cyborg yelled, firing his sonic cannon and slamming his metal hands into them. "Nothing's hurting them."

Robin snapped out his bo staff, shot a grapple into the roof and swung himself across the room. Using his swing's momentum, he dropped down and struck a full arc swing onto a creature's head. He winced as his staff shuddered, jarring his shoulder before snapping on impact.

"Azurath, Metrion, Zinthos!" Raven yelled, her eyes glowing as she sent out spikes of her power. Her magic tore through the creatures, driving holes through them. Upon impact, the creatures crumbled into dust that collapsed.

"Geez Raven, what are doing?" Cyborg asked, shocked.

"They aren't human. They aren't even from around here." Raven told them gravely. "The closest word that fits for them is a demon. They're resistant to our equivalent of magic, so you won't be able to easily hurt them." She warned, before turning to see Beast Boy in bear form tear through three of them at once; one with each paw and the third with his mouth. "Huh. That's weird."

"Never mind that. How do we stop them?" Robin asked.

"We need to get back to the Tower. Whatever they are, they're originating from there." Raven told him.

"But what of those in the city?" Starfire asked. "If we can't hurt them, how much damage will they do?"

"Much less than if we continue to let them escape." Raven told her grimly. "And we can't fight them unless I get back to the Tower to gather the spells that will either null their resistance or increase our power, because it looks like only I, and somehow Beast Boy, can fight them."

TTGTTGTTG

Cyborg checked the sensors for the Tower and gave a slow nod. "Everything checks out. My sensors can't detect anything moving in the Tower."

Robin nodded, glancing over at Raven, who shook her head. "I can fight these things but I can't sense them, at least not accurately enough to tell if any are lingering in the tower."

Beast Boy sniffed the air and grimaced. "I can. These things stink, and there's a massive stench coming from the living room."

Starfire grimaced. "I am wishing that they had found another location. I am growing very tired of bleaching the couch."

"You've been bleaching it?" Cyborg demanded. "I thought Beast Boy was spilling tofu on it."

"We can worry about the couch after we deal with whatever's in our Tower." Robin told everyone firmly. "Raven, you seem to know how to fight these things. What do you suggest we do?"

"You three stay back when we enter the living room. I'll blast anything in the room before heading to my room. Once I have gathered the necessary spells to level the playing field, we split up and hunt these things down." Raven said calmly.

"What about us?" Cyborg asked. "I don't mean to be picky Raven but three of us can't hurt these things. What do we do while you research?"

"Do research of our own." Robin told Cyborg before Raven could. "If those things are coming from our Tower, than there must be either a portal or a tunnel, either of which we can detect. And we all have contacts from all over the world, and other worlds. We can find out how big of a problem this is and whether or not we need reinforcements."

"And don't forget dude, I can fight these things." Beast Boy reminded him. "I can totality take anything that comes through that portal."

"That's well and good Beast Boy but that means less than half our team can do something. What do we do to keep Raven from being knocked out or you being killed off?" Cyborg demanded. "We need a better plan than Raven and Beast Boy kill everything."

Robin sighed. "Until we can damage those things, that pretty much has to be the plan. We'll have to play look out for now."

Starfire and Cyborg grudgingly agreed, and the group entered the Tower with Beast Boy leading the way. When Raven started to protest, he told her, "Look Raven, if you lead the way you're more likely to get ambushed and knocked out or worse. You're still our best chance of fighting these things and you're our healer to boot. Now me, I'm a runty green guy. If I take a hit to the head, I'll groan and grumble but I'll live and probably just turn into a ram and head-butt them for payback. You on the other hand could be knocked out and leave the rest of us helpless. Let me go first."

Raven ceased arguing after that and allowed herself a little bit of space behind Beast Boy, a strange look on her face. Since when did Beast Boy make sense when he talked to her? This whole incident was spiraling out of control. Not only were most of her friends helpless, not only had she never seen most of the creatures she was fighting, but now Beast Boy, one of the few constants in her life, was acting less and less like himself. She needed to get her wits about her and figure this out before she went insane. Well, more insane.

A loud clang alerted her as Beast Boy in the form of a gorilla knocked the door in. Cyborg let out a groan and Beast Boy morphed back into human form with an apologetic grin. "Sorry the door jammed, there's no power in this room."

"No power, BB? The tower's in full defence mode," Cyborg protested. "Those doors should have enough power to keep me running for months running through them."

Beast Boy shrugged, "You got me there dude, I'm not an electrician. All I know is that there's no power in these doors either to keep people out or even open up with"

"Beast Boy's telling the truth," Robin interrupted Cyborg's starting rant. "If those doors had power he wouldn't have been able to touch them let alone knock them down. I don't think that any of the other security measures are working either because we're coded as intruders and we haven't faced a single security measure."

Starfire frowned and put her ear up to the wall, "I agree that we have not yet been attacked but if we have not been attacked I still hear the power going?"

Robin cocked his head curiously, "What was that Starfire, you hear the power's going? How can you hear the power's going?'

Beast boy asked, "You don't?" Honest curiosity in his voice.

"I do not hear the actually power going," Starfire explained quickly, "I do however hear the generators humming and do note the lights are on. Also friend Cyborg said he turned on the systems of security and he is well connected to the tower."

Robin glanced over to Cyborg for confirmation, Cyborg nodded. "My systems say that everything we've got is on, every security measure we have is running at 100%."

Robin looked puzzled, "So does that mean that something is blocking the flow the power or-"

"Or someone is draining the power, from the whole tower, especially this room," Raven finished.

Beast Boy lightly cleared his throat, "Dudes, weird question." Everyone turned to look at him, "If someone's powerful to drain electricity from the tower and skilled enough to drain only from the security systems why are standing in the door way that we just conveniently knocked down to announce our presence into the room, shouldn't we be walking in and preparing for the worst in battle instead of sitting and waiting in the hallway?"

The Titans all exchanged looks, suddenly realising exactly what Beast Boy was telling them. With said Titan leading the way the Titans charged into the living room, eyes wide and weapons ready, looking for any trouble. Raven was glowing with black energy and Beast Boy had shifted into his T-Rex form, baring his teeth and preparing to tear through the demons he thought were waiting.

Instead there was just a still figure in the centre of the room. The Titans all froze, staring down at the still being in shock. Beast Boy shifted back looking around the room with confusion clearly written all over his face. "Dude, really? We get Hell on Earth in Jump City and the source of it is some guy crashing in our living room?"

"Beast Boy, get away from him." Raven snapped. "I don't know what he is but I sense power. He makes my father look weak."

Beast Boy sniffed the air and shook his head. "Not him Rae. Whatever he's tied to, yeah but not him. His aura isn't right for it."

Raven was about to reply when Robin snapped, "Titans! Trouble!" He pointed to the air behind the prone figure. It was glowing an odd purple light, before letting out a colorless burst that blinded the Titans. When they could see again, the purple light filled a sphere that floated in the middle of their living room. "Not again." Cyborg groaned. "The last time this happened I spent months cleaning the windows."

"I am more worried about the fact that there are now people in our living room and they are coming towards us." Robin stated, drawing his staff.

Starfire, her hands glowing green, asked, "But are we able to hurt them yet?"

"We'll find out." Cyborg yelled, letting out a burst from his cannon. The creature stumbled back a few steps before snarling.

Beast Boy had already shifted and leapt, his tiger form pinning and clawing the first one. Raven floated where she was, chanting as she surrounded her friends in a black sphere. "Stay back!" She ordered the others. "Beast Boy and I can handle them." She started her chant, only for one of the creatures to pick up the couch and throw it at her. With a grunt, Raven flew across the room, causing her shield to dissipate.

"Raven!" Robin yelled. Beast Boy let out a guttural snarl and tore the creature to shreds before shifting into a bear and charging the others.

"Robin, you check on her. These things are starting to react to Starfire's powers too. We'll help the grass stain." Cyborg told him.

Robin nodded and ran over, noting the sounds of the battle behind him. He quickly checked for Raven's pulse letting out a sigh of relief as he did so. A quick glance at the wall caused him to grimace. Cyborg had upgraded the Tower walls to survive him and Starfire hitting them at the same time. Currently there was a dent in it roughly the length of Raven's body, and the couch was still on her legs. With a grunt, Robin lifted the corner of the couch, wishing not for the first time he possessed at least a touch of super strength.

The couch did move though and Robin quickly checked Raven over. To his surprise, he couldn't feel any broken bones or extensive damage. Other than being unconscious, Raven seemed fine.

Before he could let anyone know, Starfire and Cyborg both slammed into the wall on either side of him. Cyborg shook his head, trying to clear it. "Good news, we can hurt them. Bad news, not enough."

"But we did provide enough of a distraction for Beast Boy, did we not?" Starfire asked tiredly.

Robin turned to look and his eyes widened. Beast Boy, in the shape of a velociraptor, was tearing through the creatures leaving shreds of them behind. More were coming but he didn't seem to care or slow down. If two more appeared after he killed one, those two were gone before they had a chance to attack. "When did he get so good?" Robin wondered.

"What, not holding back when fighting the bad guys?" Cyborg asked. "Rob, if we let green bean there hand the police quarter sections of the villains, he'd be even better than Raven. But we don't so he's not. Speaking of Raven, she seems to be coming around."

Raven was starting to stir, shaking her head slowly and blinking, everything momentarily fuzzy. "Stupid shield." Raven muttered. "Need to work on that..."

"Raven?" Robin asked hesitantly staying just out of reach. "You ok?"

"Relatively." She said. "And I think I've figured something out. Where's Beast Boy?"

"Over there." Cyborg pointed. "Taking those things out by the dozen."

"Not good. Those things aren't real. They're constructs. Someone is sending golems after us to gauge our strength. We need to shut that portal, and that guy is the anchor." Raven pointed at the prone figure, still oblivious to the battle.

"Is he even alive?" Robin asked her.

"Doesn't have to be. Give me a moment. Robin, do you have any bombs on you?" Robin nodded slowly. "Good. Starfire, Cyborg, you two shoot anything that comes near me. Robin, if anything gets hit by either of them, hit it with an explosive disk. I only need a moment."

The other Titans nodded. "What about Beast Boy?" Starfire asked, before a roar caught her attention. Turning, the group saw a T-Rex charge through the group, destroying another group of golems. "On the second thought, we had best be leaving him be."

"Ready?" Raven asked. The others nodded. "Three, two, one, go!"

Starfire flung her starbolts at multiple golems that had broken from the group dealing with Beast Boy, her attacks closely followed by small orange disks that exploded on contact. Cyborg took similar action, only he fire small rockets from his shoulders following his bursts from his cannon. With the golems distracted, Raven floated down beside the prone figure, her power forming a dark aura around her.

She knelt beside the figure's head and let out a deep sigh before willing her power into her voice "Do your duty!" She ordered, her robes flashing white for a moment as her power surrounded the other body.

The figure bolted upright, eyes glowing a crimson red. He floated in the air for a moment, before letting out a deep, guttural yell. "Return! Seal!"

Raven closed her eyes and raised her hands, expecting a similar blinding light as before but instead, all there was a quiet hum. The golems all shuddered and fell apart, forming piles of dirt across the living room. One of the golems let out a screech and its form fell away, revealing a humanoid body that started to glow brightly before being sucked into the portal. As it phased through the portal, the sphere faded away, leaving a faint purple tint that was slowly fading away.

The figure shuddered and shook his head. "Gods above and below." He muttered, a hand going to his temple. "That was a bad one. I hate crossings."

Raven stood up, drawing her power into an aura projection around herself. The figure looked up, his eyes wide. "A child of Trigon? Here? But that must mean... This is Junp Cit-ie?"

"Jump City." Robin corrected, his staff in his hands and ready. "Who are you?"

The figure shook his head. "I found them. The Titans. Maybe they will be enough." He rolled his shoulders and stood up. "I am Krandu, of the Titans North. And my world needs your help."
