Disclaimer: I don't own the Teen Titans, Young Justice, The HULK, or any of DC Comics, or Marvel Comics respective characters that are used in this Fanfiction.

A/N: the Hulk will be a Leaguer eventually, but I'm probably gonna make him fight the Young Justice team- who I'm having be made up of all official members of the Teen Titans as of the movie "Teen Titans: Trouble in Tokyo", and Garth- the original Aqualad- will be called Tempest, as well as Static, Gear, and Supergirl, and Speedy will go by Red Arrow- a lot, as well as some of the more powerful Justice League members- mainly Wonder Woman, Super Man, Batman (because he would find a way to fight- and stop- him eventually), Red Tornado, Captain Marvel, Captain Atom, Martian Man-Hunter, Aquaman, Green Lantern, and Hawkgirl. Oh and I'm gonna give the hulk more powers then just super durability- bullets bounce off of him- to attacks, super strength, and super stamina all of which he has in the comics. Oh and the beginning this FF will take place in December, close to Christmas.

Marvel Universe:

The Hulk had been fighting a gamma monster called The Abomination, and a couple of his goons, for a couple of minutes now, when Abomination had grabbed hold of a little girl.

"Stop resisting us or I KILL the girl got it dumbass!" said Abomination, but the only thing The Hulk cared about was that an his long time enemy had just brought an innocent CHILD into their fight and was using it to threaten him into letting himself be killed, as well as knowing that Abomination might still kill the girl just because he wanted to.

"RRRRAAAAAHHHRRRRR, HULK SMASH PUNY ENEMY!" yelled Hulk in response to the threat as he built up energy for an attack- that he had learned he had not even 2 days earlier- that was basically a gamma irradiated roar, that his more docile, and Human, half- Bruce Banner- called "Hulk's Rage" that he knew would finish the fight without hurting the girl- except for some pain in her ears, the only affect he found it had on normal people- because it only worked properly on people with powers, and he could sense that she didn't have any- yet another power he had recently developed.

"Then you've sealed her fate, I hope you like being chased by everyone for causing the death of a little girl now, along with being a monster that everyone fears, HAHAHAHAHAAAAA!" was Abomination's reply to what he believed was an empty threat- even from someone as powerful as The Hulk- because Hulk would never be able to reach him in time to stop him from crushing the life out of the girl, when all-of-a-sudden the hulk roared as loud as he could.

"!" roared the Hulk with all his might, sending out a sonic wave of gamma energy that hit Abomination like a person hit by an oncoming train brick, which caused Abomination to let go of the girl as he was thrown back into a large building- that had already been evacuated- by the power behind the attack, and the sheer rage in The Hulk.

Five minutes later, after the Hulk had finished running from the military- which had arrived just seconds after Hulk beat Abomination- he saw a strange, swirling light of a spectrum of colors- kind of like the Rainbow Bridge of Thor's/Hammer Man (Hulk's words) whenever he came to Earth- appear in the sky and the next thing he knew he was being pulled into it.

DC Universe:

Some scientists for S.T.A.R. Labs, located in Star City USA, were currently trying to open a new wormhole- new because a few weeks ago when they had come to the lab, there had been one that had opened up sometime in the night and had let a Gila Monster— a type of poisonous lizard native to the United States South west and some Northern parts of Mexico— into the lab, they knew it had come through the portal because they were nowhere near the native habitat of the lizard, and there were none in S.T.A.R. Labs because they weren't studying lizards this year.

But when they finally caught the lizard, the wormhole had already closed off- before they could see where it would lead to, because when they examined the lizard's DNA they found that it had a unique marker that told them it was from an Alternate Reality.

When the generator they'd built to open the wormhole again finally punched a hole through to- at least they hoped it was- the origin point of the AR lizard they found that a few seconds later something incredibly powerful was being pulled through to their side, they didn't know if it was hostile or not, so they decided to shut the experiment down when they found that they couldn't, it was malfunctioning, and then they saw what they had inadvertently hooked and They could tell that whatever it was, it wasn't happy- in fact it looked like pure Rage incarnate, and they were in its crosshairs.

"ROOOAARR, HULK SMASH PUNY MACHINE!" shouted The Hulk with rage in his eyes, as he started to attack the machine that he felt was blasting him with some sort of laser.

When he finished destroying the machine- which thankfully closed off the wormhole that it had artificially created- he turned his attention to the room he was in and started to smash his way to the surface.

The safe, relatively speaking, experiments in S.T.A.R. Labs were above ground, but the more questionable and dangerous ones were done 250ft below ground in a bunker that even Superman would have trouble trying to bust into- but could do in about 3 minutes.

The Hulk was travelling fast so that he could get away before the military showed up to capture and study/dissect him to see if there was potential for a bioweapon or super soldier serum from his blood (he still thought that he was in his reality) but the Hulk had no problem breaking out of the place.

In fact the Hulk had reached the surface even faster than the Flash would have, he would have been about 2.5 minutes- because of the defense network designed to defend the labs and keep dangerous things in- Hulk took 1 minute, the reason it took so long is because the Hulk had been calming down after his fight with Abomination before he was dragged into the swirling rainbow-like light, so his anger had to go back up to its more destructive levels.

A few thousand miles away from Star City, in a base called known as Mount Justice, but commonly called "The Cave" because it's built into a dormant volcano, the group of young heroes called Young Justice was gathered by Batman to receive their missions- because there were so many members they had been divided into groups that would take individual missions so that the covert aspect of most of their missions wasn't compromised, and so that they didn't have in-fighting between the groups during missions.

Batman was issuing a mission to the founding members of the team- the last ones in the room- which were Robin/Dick Greyson, Aqualad/Kaldu 'Ahm, Miss Martian, Artemis, Kid Flash/Wally, Red Arrow/Roy Harper, and Superboy/Conner Kent when the alarm went off that signaled a threat.

After Batman checked it he thought that this would be a good time to check the progress of the team as a functioning unit- they had been together for 3 years now and had faced many challenges that had impressed Batman, though he didn't let it show, and he had been waiting for the chance to make Young Justice a world player on the hero scene, and he felt there were ready for mass public scrutiny.

He turned to the team while displaying the T.V. broadcast on a screen above his head to show the team their mission.

"This will be your mission." Said Batman as he turned on the volume of the News feed coming in from Star City.

"…we are on the scene where the destruction by the unknown creature has spread from S.T.A.R. Labs to the rest of the city as officials from the police and some military units have tried to subdue the monster that burst out of the basement levels of S.T.A.R. Labs that are heavily defended to stop anything dangerous from getting loose. But it seems that they have created something that would give Superman a run for his money, as witnesses say that it took this monster just 1 minute to break out. All I can say is that the world had better be ready for the beast that's been unleashed unto us….zzzghckkk" as the connection broke when a piece of debris hit the camera lens.

"Wait, play the video feed back. I think they caught a picture of whatever was attacking." Said Robin as he looked for what he has seen before the screen cut out. "There, what is that thing?" questioned Robin when Batman got to the image he had seen, what was shown was a huge green monster, standing about 15feet/4.57meters tall and weighing about- at least by Robin's estimate- 2,580pounds/1,170.27kilograms, picking up an army-tank like it was a child's toy.

"That is what you're going to find out, well also trying to stop that thing from destroying the rest of Star City, I'll request Superman and Wonder Woman to join you- but this will be your mission that will reveal Young Justice to the world as a separate team from the Justice League, if you pull this off then your receiving missions from us will be over and you'll be free to choose the missions for the whole team, and ALL of its members. Don't disappoint me." Was Batman's reply and advice to the team for their most challenging mission yet, because- though they didn't know it- they were to face a force of nature unlike anything they've ever seen before- pure animalistic RAGE.

A/N: I want ideas for some more powers for the Hulk- that appear because of an effect of crossing through to the DC Universe, and no I will not take Flight.
