Hello again, folks! I'm still feeling the writing bug, so here's the first part of the new series. I'm going into full crossover with the DCAU here, as you may well have guessed, which should make for some interesting material to work with. Anyway, for the sake of the timeline, we're starting at the beginning of Season 3 of Teen Titans. But enough delay, on with the story! As usual, I own dick. Teen Titans is all DC and Cartoon Network's.

Episode 1: A Better World

"Sector 4 is all clear, Watchtower. Proceeding to Sector 5." Robin spoke into his helmet's radio, swerving between traffic with his teammates close behind, flying just high enough to not interfere with the flow of cars. It was another quiet day, thankfully, and if thing's held up it would be the fifth in a row. He almost couldn't remember a time when crime was rampant, even if had only been two years since things had changed He was proud to be a part of the people making sure it stayed that way, too. So were the others, he was proud to say.

"Changeling to Robin. We've got a protest at JCU, police are losing control. Advise?" The familiar, youthful voice chimed in. Robin frowned as he mulled that over, the others obviously having heard it if the growing scowls were anything to go by. It wasn't always tasteful, but order had to be kept, and it was their job to see to that in Jump City.

"Disperse them. Use whatever force you need." He responded, speeding up just a bit as he continued his patrol. He heard the click on the other side, signing the green teen's acknowledgment.

"Copy. We're responding now. Shouldn't take long, sir." He couldn't quite help but smile with no small amount of pride at his teammate's professionalism. Changeling had done his absolute best to emulate the sense of power and authority, the righteous justice that Superman bore at all times now, idolizing him and the rest of his team. He'd even changed his alias from Beast Boy to try and choose something more respectable after he left the Doom Patrol. It had certainly impressed the rest of them, especially Terra, and Robin was all too happy to have such a dedicated soldier on his team.

The next voice over his comm was older, deep, but just as familiar as Changeling's.

"Robin, this is Batman. I need all of Team 3 to report to the Batcave ASAP. I've got something you're going to want to see." That came as a surprise. Sure, he'd re-connected with his old mentor over the last year, almost got to the point where he was ready to call him father again, but it wasn't like he was invited to the man's lair much anymore, and never the entire team. If he wanted them all there, it must have been for something vital. There was no hesitation, and immediately he raised his hand to signal Cyborg and Starfire to break their route and follow him.

"Copy that, sir. We're on our way." He switched channels then, turning sharply at a corner. "Changeling, belay that last order. We're all to report to the Batcave. The Lords have something to show us."

TTTTT

"Attention!" Cyborg barked when they saw the gathered Justice Lords; Batman, Wonder Woman, Hawkgirl, Martian Manhunter, Green Lantern, and Superman. The teens all snapped to a smart salute, perfectly in unison and unmoving. They looked like any good military unit, garbed in their uniforms (Black bodygloves trimmed with white, polished metal gauntlets, shoulder and shin guards along with heavy combat boots and utility belts. All but Cyborg for obvious reasons, though he'd painted his cybernetics in the appropriate colors.) and as neat as imaginable. Superman turned and gave them an approving nod, raising one hand.

"At ease. I'm very impressed with how you handled that riot last week, by the way. Only ten casualties is a goal we should all try for." They all swelled then, Changeling look positively thrilled at his idol's praise, which only made Terra smile at her boyfriend proudly. It was back to business then, however, with the teens starting toward the massive monitor that was the centerpiece of the Batcave. The Lords were looking up at what looked like an old recording of one of their battles from before they'd taken their rightful place. Robin wondered why they were reviewing such a thing, or what called for his team being here.

"What is this? Some old video of us?" Green Lantern broke the silence, looking intently at the footage playing out in front of them.

"Except we never had a fight like this with Luthor." Wonder Woman added, turning down to look at her husband, seated in his high-backed chair. Batman frowned as he watched the fight unfolding before them; older versions of themselves battling Lex Luthor, which immediately set off alarm bells for Robin.

"You're right; we never did, but they're having one right now." Batman answered. All eyes turned to him in shock.

"They?" It was Hawkgirl, looking as surprised as the rest of them at dark knight's announcement. Batman didn't bother turning to look at them as he responded.

"We're looking at another dimension. Live." They all stared at the screen for a long moment then, shocked at the sight before them. Wonder Woman spoke up again.

"It's just like ours."

"Almost." Batman said, pointing to the screen. "But their Flash is still alive."

"So is their Luthor." Superman added, his voice full of contempt for the man fighting their alternate selves.

"They don't call themselves the Justice Lords. They're the Justice League. That's not all." Finally, Batman turned slightly, flipping the screen to another image. This time, it was Robin and all of the others fighting, engaged with some gigantic, rock-like golem. They didn't wear any sort of uniform, however, and certainly didn't have any sort of military training. "They don't have a Justice Lords Youth Brigade, either. It's just the six of you. They call themselves the Teen Titans."

There was a long silence from all parties, the image on the monitor now switched to show both battles unfurling, Titans and League beating back their villains in never-ending struggles.

"It's sad." Wonder Woman said then, looking appalled by what she saw, a trace of pity in her voice as well.

"Yeah. Their world's the mess ours used to be." Green Lantern added in agreement. Hawkgirl frowned at the sight, her mace in hand.

"It's too bad we can't help them."

"Who says we can't?" Batman said then, and Robin swore that he almost heard amusement in his mentor's voice as he gestured to their right. On that exactly cue some strange machine hummed to life before their eyes; a platform with two tall metal poles flanking either side. Between the poles there was a crackle of energy, growing larger by the second until it filled the space between the poles completely, swirling yellow on black. The Lords started toward it then, and the Youth Brigade team followed after them at a respectful distance.

"You've been a busy little bat, haven't you?" Robin heard Superman mutter to Batman. Obviously they weren't getting along as well as they used to.

"What else is there to do around here anymore?" Batman answered. He supposed he could understand that sentiment, but in the young man's books, quiet was good. It meant that they were doing their jobs right. They all stopped before the portal then, looking at the massive construct sternly. Green Lantern turned to face Batman then.

"This can take us to that other dimension?" He asked.

"If we decide to use it." Batman answered.

"Why wouldn't we?" Hawkgirl asked, seeming to perplexed as to why there would be any other option available to them. Batman looked at her with a frown.

"You're talking about helping them. But would they accept it; our kind of help?" They turned back to the monitor then, the battles between the supers starting to wind down, but only for the moment, they knew. It was rinse and repeat in those days, and they were still stuck in them. Because they lacked the strength to do what was needed.

"We'll stand by whatever decision you make, sir." Cyborg said with a respectful nod to Superman, his voice filtered by the full mask he now wore. He'd long since given up all of the human components of himself he dared to in order to better serve the world; only his brain and heart were still flesh and blood now. The others all nodded in agreement.

"Personally." Raven said. "I wouldn't mind showing them what I'm like now that I've got some proper backbone. Now that I'm not afraid of that pathetic worm that calls itself my father." Both Lords and the Youth Brigade looked at each other then, mulling the choice over.

It was unanimous in the end.

TTTTT

"Booya! Another win in the bag and nobody got hurt!" Cyborg cheered, falling back into the couch and swinging his feet up onto the table. Raven joined him silently while the others shuffled off with tired groans. They'd been running ragged for the last week straight, chasing a new influx of villains from Gotham and Central City's B and C lists. Firefly, Bloodsport, Evil Star and Blockbuster had all shown up within the last two weeks, and every day it seemed like another was on their way to try their luck. Starfire groaned as she too fell on the couch, face-down and looking ready to fall asleep on the spot.

"We are needing of a vacation soon, I think." She said, her voice muffled by the cushion. Raven didn't reply to that, simply pulling the control for their Xbox into her hand and switching on the console telekineticly. Cyborg was still surprised they'd actually gotten her to use the thing, but even since she'd found The Chronicles of Riddick: Escape From Butcher Bay she'd been playing every chance she got.

"Riddick speaks to me." Was all she said when he asked her about her new-found fascination. He had a sneaking suspicion that it was partially motivated by a huge crush on Vin Diesel, but he didn't have the guts to say it to her face. He could see Robin groaning as he reached out to grab a drink from the fridge, and Terra and Beast Boy were slumping down at the other end of the couch, snoring audibly. He sighed, shaking his head and turning to the screen as Raven stealth-killed the first of the prison guards.

"Starfire might have a point..." Robin said, taking a long pull on the bottle of Coke. "Maybe we should see if Supergirl's willing to watch town for a little while."

"You'll have to wait on that, I'm afraid." Cyborg and Raven looked up sharply, recognizing the voice, but not seeing it come from its normal source. Beast Boy was stirring groggily, surprised to hear his own voice, Terra doing the same.

The speaker looked like Beast Boy...at least in his skin-color and face. The similarities ended there however. Where Beast Boy was wirey and small, his stance as carefree and happy as could be most days, this green teenager was broad and muscular, his body in peak physical shape and his hair trimmed in a high and tight crew cut. Everyone was at full alert now, though Cyborg could swear he saw Terra unconsciously ogling the clone or whatever it was, practically seeing the hearts in her eyes and floating above her. More surprising, it looked like Raven was staring as well.

"Who...are you?" Raven spoke up, her gaze suddenly returning to normal as she eyed the intruder. Not Beast Boy turned to her with a firm expression, obviously not in the mood to waste time.

"Changeling. I'm from another dimension, makes sense when you think about it. Time's short so I'll make this quick; Our worlds are in danger right now and we need your help to put a stop to it."

"...interdimensional warlord looking to take over our realities or destroy them?" Robin asked in a tone of 'Not this shit again.'

"Not your first time at this, I assume?" Changeling's tone didn't change, looking over the Titans critically.

"Uh...why do I look and talk like a marine?" Beast Boy asked, fully alert now, albeit confused. Changeling turned to stare at his mirror self, frowning.

"Better role models." He turned back to Robin. "Good guess. We're outnumbered on our end and we figured that you'd be interested in making sure our dimensions don't collapse in on each other." All eyes turned to Raven for confirmation of his words. She frowned as she eyed the new arrival with some confusion.

"I can't get a read on him. Like his mind's been altered." She said, eyes narrowed suspiciously.

"Specialized training, we've dealt with one too many empaths and mind-readers to not prepare. Should I assume you're not interested in saving multiple dimensions?" Changeling's tone was curt, the trace of annoyance unmistakable. The Titans all looked at each other for a long moment, considering. It could well have been trap of some sort, it would hardly be the first time someone had tried something this esoteric to fool them. Then again, dimensional disturbances weren't uncommon these days, it seemed, so it was good a chance that he was telling the truth. Finally, Robin turned back to the mirror Titan, nodding slowly.

"Alright, we'll play along for now. This had better not be a ruse." Changeling nodded in return, gesturing for the team to follow him. He led them down the hallway toward a swirling black and yellow portal, striding toward it's crackling energy.

"Just follow me and follow whatever orders you're given, and we'll have this done as quickly as possible." With that he stepped into the portal, and the Titans followed after him.

TTTTT

The room they entered was purely white, lacking any form of doors of windows, forty by forty feet, and there was no sign of Changeling. It seemed to be little more than the inside of a white box, and immediately Cyborg groaned in frustration.

"This is what we get for trusting strange interdimensional copies of ourselves. How the heck do we get out of here?" Before anyone could response, the walls and floors were suddenly alight with electricity, jolting through each of the Titans. They all screamed as their muscles stiffened and pain racked their bodies, all but Starfire collapsing under the assault. The Tamaranian snarled and tried to form enough energy to blast their way out, but a fresh, more powerful jolt of lightning struck her. Slowly she too slumped down to the floor with her friends, her vision fading before she lost consciousness.

Outside of the box, the mirror Robin looked on with approval as Cyborg confirmed the Titans were subdued. Batman offered no outward expression of his feelings on the work, though Robin expected that he was satisfied with how it had worked out. The others were fixed on the video feed of the unconscious superheroes, marveling at their mirror selves, save Raven who looked disgusted.

"She's still a pathetic little girl. Terrified of our father. I'm going to enjoy showing them what I can do when I'm not bound by that foolish prophecy." She spat out the words. Batman turned to her then.

"You'll be getting your chance. Take Terra with you, scout out their Jump City. Show the scum there you mean business. We'll deploy reinforcements when Superman's team sends in a report." Raven and Terra gave a smart salute, starting toward the portal purposefully. Robin knew they'd do their job with the utmost care, and of course a proper dose of righteous violence to put the criminals in their place.

"Should we put them with the other prisoners, sir?" Cyborg asked of Batman, his fingers flying over the controls before him, letting the box open up.

"Yes. I want them all secured within the hour." Another series of sharp salutes came, Cyborg and Changeling starting toward the unconscious Titans, the green soldier morphing into a gorilla to scoop up four of them under his massive arms while Cyborg threw the other two over his shoulders. Robin turned to the man he had once called his second father, hands folded behind his back.

"Do you think we can really help that other world? With how many super-criminals they have over there?" Batman turned to him, his expression as stoic and unmoving as ever.

"We dealt with that problem once before. No reason we can't do it again." There was a pause, and then slowly, the man reached over to clasp the teen on the shoulder. "I know your team can do this. We'll make a better world of it."

TTTTT

"Thank you, ladies and gentlemen! You've been a lovely crowd, but now I must be off! The generous fee is appreciated!" Mumbo declared with a bow, the heavy dufflebag of cash swaying over his shoulder as his magically bound and gagged audience struggled against their restraints. Things were going well for once, and the Titans were nowhere to be seen. He wasn't sure if they were distracted by one of the newcomers in town or if they were just under the weather, but he wasn't in the mood to care at the moment. All that concerned him was getting his haul back to his hideout.

He kicked the door of the small bank open and bolted down the street, his speed magically augmented. He could hear police sirens in the background, but he would be long gone by the time they got to the scene. Just a matter of getting into an alley where he could disappear long enough to get a teleportation spell going, just a little further...

Mumbo stopped in his tracks, cursing his luck at the sight before him. Terra and Raven stood there, scowling and floating above the sidewalk. They looked...different, however; Terra's hair was cut short in a pixie style,and in far better physical shape than before. Raven was much the same, and she wore no hood this time. In fact, both of them seemed to be in some new black and white uniform.

"New fashion statements, Titans? Impressive, but a bit Orwellian-esc, I think." Mumbo said almost casually, his wand flying into his hand. The two girls looked disgusted .

"How did we ever stand pitiful men like this?" Raven asked as if Mumbo wasn't even there. Terra shrugged with seemingly bottomless indifference.

"We coddled them. Good thing we learned a better way." Mumbo was visibly confused now. What were they talking about? Didn't they notice there was a supervillain standing right in front of them?

"Well I'm afraid that's a lesson that will have to wait for another time!" The magician shouted, his wand flashing with light. A cloud of doves burst out toward the Titans, both swerving to avoid the avian cloud and providing Mumbo with the distraction he needed to call on his next spell. It was a new one he'd just perfected, and if all worked out it would put these damned kids out of commission for months. He started to channel the energy, his wand crackling with power as he mumbled the words.

There was a flash of blackness before the blue-skinned man and then, suddenly, the energy dissipated. Mumbo blinked, staring at his wand in disbelief.

"What? But...the words were all right..." And then his hand slipped oozily from his wrist. He stared at the stump for a long, horrifying moment. The pain hit him a second later, and he screamed as he fell to his knees clutching his arm.

"Simple. You've been disarmed." Raven said, the white glare in her eyes fading as she let her feet touch the ground. She was smirking as she sauntered toward him with Terra in tow. The geomancer had pulled a large sliver of rock from the boulder she'd been floating on, willing it into the form of a spear. Mumbo looked up at them with terror in his face.

"W-what...t-this isn't you. You don't do this..." He croaked, tears starting to fill his eyes and stain his domino mask. Raven just looked down at him with amused contempt.

"We do now." She turned to Terra then, nodding. Mumbo didn't feel the stone spear pierce his chest, be he was aware of the blood coating the crisp white fabric of his shirt. The pain only him him when the rock had found his heart. A few seconds later the blackness fell over his vision, and he felt nothing ever again.

TTTTT

And that's a wrap. Part 2 will be up fairly soon, since I'm still unemployed and have plenty of time on my hands. All reviews are appreciated, folks.
