A/N: Hi fellow readers, this is my first fan fiction, so constructive criticism is very welcome. I hope you enjoy my first story! Don't forget to review.

Disclaimer: I don't own Avengers or Young Justice.

Tony Stark AKA Iron Man was tinkering around in his lab, his new project travelling between different dimensions. The lab door opened with a woosh and in came Cap.

"Hi, Tony, what are you doing?" Steve asked, looking at the extremely odd contraption with swirling lights and moving pieces.

"That Capsicle, is a dimension transporter. It opens a portal to a whole new dimension!" Tony completed his explanation by lifting his arms to the heavens and a smirk that showed he was very impressed with himself.

Steve looked skeptical, "Really, you sure it will work I mean really new dimensions. I'm not saying I doubt it will work, but should we? Wouldn't that mess up the balance of the Universe or something."

"Nah, well maybe, but I doubt it." Tony leaned against the machine accidentally pushing the red 'DO NOT PUSH' button. The machine emitted a high pitched alarm, with red flashing lights, attracting the attention of the rest of the avengers.

Clint burst out of the vent upside down with an arrow knocked. Natasha rushed through the door guns blazing. Banner came next through the hole Thor made with his hammer raised looking battle ready.

About five feet off the ground was a black shimmering portal lightning to purple at the edges. Everyone watched battle ready as a little boy who couldn't be older than eight nine years old came hurtling out of the portal and into the wall on the other side of the room, the portal disappeared, the machine powered down and Tony deftly shut the alarm off.

The room was silent for a moment, Then Bruce shifted into Doctor Mode. He rushed over to the unconscious boy. He was very skinny, bordering on emancipated. He was dirty from head to toe, his clothes were mere rags, the pants were ripped at the knee, holes everywhere, the boy's hands and feet were covered in mud and blood. His once white shirt was also holy and filthy. On his neck was a bulky metal collar with a red light flashing on it and a humming sound emitted from it as if it had electricity running through it. His face was brown with dirt, his skin and hair color couldn't be determined because of the grime covering them. The kid looked like he came from a war zone. Maybe he had.

Bruce sprinted into action, he checked the boy for a pulse, finding a faint and labored pulse. He checked to make sure he didn't have any neck or back injuries, he didn't.

"Thor, get him to the medical bay hurry!" Bruce yelled at Thor. Thor hurried over, picked the underweight boy up and running to the med bay. The rest followed quickly.

"I wonder what happened to him, I hope he'll be okay." Natasha said worried, showing her rarely seen motherly side.

"I won't know until I can examine him properly." Bruce spoke in a grave voice.

Boy's POV:

Darkness it's all I can see, nothing new there, it's always dark, but the pain all over my body. That's what I find disturbing. True, my body is almost always in relative pain but not like this, never like this.

I want to wake up, make sure my family is okay, but my eyes won't open. I'm waiting in the darkness for what seems like centuries, I hope it's not centuries, I don't want to wake up as an old man. That would not be crash at all.

Eventually my eyes open, finally cooperate with my mind. When my eyes open, bright white light attacks me. Oh no, not again, I can't be back in the labs, no no no no! I start thrashing around, surprised and relieved that I'm on something soft and warm, not strapped into a pod. Giant, warm, firm, but gentle hands grabs my arms and hold me down.

"Hey, it's okay you're safe no one is going to hurt you." A huge man, with a clean face, warm blue eyes and short, neat blond hair says to me. The man's wearing a gray shirt with some writing on it that I wish I could read, Jay was gonna start teaching me how tomorrow. The man was also wearing loose gray pants. That's when I notice my own clothes, the filthy, holey, blood and mud splattered clothing is gone. Now I'm wearing really soft, comfortable clothes, the shirt has a red and yellow metal head on it and the pants have little metal men all over them. I don't know what these clothes are, they'd never hold up in a fight, but I think I like them. I reach my hand up to my neck, yep collar's still there. Mode.

"Who are you? Where am I? How the blazes did I get here?" I ask the man ignoring my pain, I'm used to it. There was something about this man that made me want to trust him, but growing up in a war torn world, that's been invaded by Aliens over 50 years ago, makes trust difficult.

"I am Steve Rogers, or Captain America. You're in Avengers Tower in New York City. Lastly you came barreling out of a Dimension traveling portal." Steve explained quickly hoping to calm the boy down.

"What's your name? Where do you come from?"

"I'm Bart and my world's been at war for 50 years." I answered hesitantly still not sure if he is trustworthy. Steve looks genuinely concerned, weather about me or the world I come from I don't know.

"Wait you said dimension traveling portal, so that means I'm in a different dimension? What year is it here?"

"2012, what year do you come from?"

"2056"

At that moment a man in a white lab coat comes in looking all doctory.

"I see you're awake, I'm Doctor Bruce Banner, are you in any pain?"

I nod my head, wary of this doctor. He puts a shot of what I assume is a pain killer into my IV, yes I know what that is I'm not completely ignorant. Suddenly the room starts spinning and things come in and out of focus, then the darkness takes me again.

Yay! First chapter done! Don't forget to review.
