A N)Hey guys. I'm still doing Apprentice, just had to get this outta my brain. So here it is. A Marvel DC crossover. With Robin, Kid Flash and Speedy. I don't own them, so don't sue me. Enjoy!

Steve Rogers rounded the corner, shield grasped in hand. Metallic footsteps followed behind him. Their pace was hurried, eyes searching the halls in front of them. Alarms had been triggered fifteen minutes ago on the Heli-Carrier. Fury had sent them to investigate the three alien heat signatures.

"Maybe it's a system failure?" Steve asked his companion.

"Cap, I made the updates on the security system. Are you saying that Stark Technology is to blame here?"

"Stark Tech? Then defiantly yes."

Tony Stark blew a raspberry at the super soldier. About to snark back, Steve stopped him by holding an arm across his chest.

"Listen."

Here were murmured voices down the hall and around the corner.

"….hurry….too long….hungry…."

"Hold on…..firewall…..back up…."

The duo slowly approached, then rushing around the corner. Three children were trapped between them and a locked steel door. The eldest had fire red hair with a yellow cap and feather on his head. He sported a red tunic and yellow boots. His eyes covered by a domino mask. A bow set with a red arrow was clutched firmly in his hand.

The second also had bright red hair, freckles covered his face. He wore a yellow and red jump suit, most of his face covered by a mask that extended from his suit. Goggles rested up on his forehead, his green eyes widened in shock.

The third and youngest boy bore a black and red spandex suit. His messy oxen hair coved the domino mask he wore. A yellow belt surrounded his waist. A blue holo-screen was being projected from his black glove. He looked unimpressed, eyes looking at the heroes and then back to the screen, his fingers continuing to tap in code.

"Boomerang."The eldest spat, arrow trained on Steve's head." So much for Joker Venoming stealth."

"Language." The youngest said in a sing song voice

"Hey! That's my tech! That's Stark Tech! Give it back!" Tony demanded like a five year old child whose toy car had been taken.

The boys exchanged looks, the yellow clad ginger raising an eyebrow.

"Yeah no, that's his Dad's tech." Yellow said, scratching his head. "What's a Stark?"

Tony fumed, waving his arms in the air and shouting nonsense words.

"Kids," Steve moved his shield to its resting position on his back," I'm Captain America. I don't know why you're here. Are you lost? The Avengers are totally willing to help you."

"Thanks." The youngest gave a wicked grin. He stopped his typing." We are lost. It's just so scary up here. I'm petrified in worry!" Steve smiled comfortingly; Tony raised an eyebrow as the two red heads pulled extremely fake sad faces." It's a shame my father didn't tell me what to do in cases like this. Did yours Speedy?"

"No, no he didn't Robin. I have no clue what on Earth to do! How about you, Kid Flash?"

"My father didn't, but my uncle did." Steve was starting to catch on to the theatrics." You know what he said?" The youngest, Robin's, finger pressed on a final button, the large doors sliding open as 'Kid Flash' smirked."Run."

The trio turned and sprinted through the doorway. Steve cried out in shock and raced after them, Tony hot on his heels. He almost caught up with them as the three kids turned a corner. He heard a terrified shout.

"KF! Look out!"

There was a grunt and a thud, a small scream and a whine of pain. Not good. Steve skidded to a stop, eyes widening in horror as he looked down at his feet. Robin has lying on the ground, red blood trickling out of his chest. Speedy as pressing his hands against the ebony's wound, blood trickling out from his hands. Kid Flash sat in a stunned position on his face, only a few feet away from Robin, still where he had been knocked down. A bloody tipped arrow rested beside the youngest.

Breakline

Clint Barton had been paired with Natasha like usual. They had searched over half of the base, both on alert. Clint was twitchy, after the Loki affair he didn't like it when the Heli-Carrier was messed with. It would take some serious balls and brains to get on.

His bow had been ready for twenty minutes, just waiting to pierce whoever was messing around with S.H.I.E.L.D. So when he heard footsteps racing towards him, he swiveled, aimed and fired. Without truly looking at his target. Not registering that he was shooting at children until it was too late.

"KF! Look out!" A masked black haired boy, slammed into a green eyed ginger. The arrow mercilessly entering his chest. The boy he had shoved out of the way grunted as he slammed into the floor on his bottom, a scream escaping his lips as he heard the whimper of pain leave his friend as he fell. The third and eldest, let a bow clatter to the ground, his masked eyes wide in panic.

The archer dropped down next to his friend, tenderly pulling the arrow out, hands pressing against the wound. The yellow clad boy hadn't moved, he sat in shock.

Clint hadn't lowered his bow, it was still held in place. Complete fear had overridden his system. He had killed before. He had been a hit man. But-he had just shot a child. A young, insanely short boy. He couldn't breathe, he couldn't move; all he could do was stare at the crimson red staining the child.

Thundering footsteps came from where the kids had, Tony and Steve stopping and gawking at the children. More footsteps echoed from the corridor to the left. Thor and Bruce meeting up with them. Gasps and whispered shouts filled the air. Tasha's gentle hands guided the bow down.

He had killed a child. There was too much shock. He had killed a boy. A kid. Clint had killed once again, this time his victim—an innocent boy.

Breakline

"Captain Cold it Robin." Roy hissed, pressing down on his brother's wound." Why would you do a dumb Nekron thing like that?"

A weak chuckled escaped his pale lips, blood trickling out and staining his paling cheek.

"W-Well, I've always been one for b-bravado."

"You idiot, you could've got yourself killed!"

"I did," Dick looked straight at him, Roy scowled."I-I'm sorry. I should've hacked faster."

"No..no. It's not your fault." Wally breathed, moving closer to his brothers. His heart pounding in fear. Robin would be alright, he was Robin. That made him invincible right? RIGHT?

Robin laughed again, more blood spilling against his fair skin." Ne vedem mai târziu frați."

"Don't give up Robin, don't you dare."Wally gasped as Roy's voice faded. No. He couldn't be…he wasn't! "DON'T YOU DARE LEAVE ME! DON'T YOU DARE! ROBIN! Robin….please….come-come back."

Roy bowed his head. Wally grasped his head, curling into a tight ball. Both boys knelt next to their fallen brother. Roy shook in rage, Wally shook in anguish. Tears brimmed in his green eyes, slowly falling out. Tears brimmed behind Roy's mask, spilling as he lifted his face up and screamed in pain. Wally released a strangled sob, eyes closed tightly.

"YOU IDIOT! WHY THE MERLYN DID YOU DO SOMETHING SO STUPID?"Roy raged, his fists balling up."YOU'RE SUCH A MORON! YOU STUPID, SENSLESS, DUMB, HEROIC, PERFECT, GENIOUS, CARING, KIND, HAPPY, SPELENDID, SKILLED, DARING, DAUNTLESS, PEPPY, AMAZING YOUNGER BROTHER! WHY DIDN'T I SAVE YOU? WHY-WHY DID YOU LEAVE ME?"Roy bit his lip, angrily brushing tears away."Why?"

Wally grasped Dick's body, leaning his head on the unmoving chest. His heart breaking when he didn't hear the rhythmic beating on the Boy Wonder's heart. Wally heard Roy scream, Roy was always one to show pain loudly. Wally couldn't. He just…couldn't.

Roy swayed to his feet, wiping wildly at his face. Blood. Dick's crimson blood stained his hands, and now his face. He gasped, eyes staring at the sickening red. His eyes looked at his baby brother, tears stinging in the chocolate brown eyes. He saw the arrow he had removed. Arrow. Like his. He was wearing the tool that murdered his brother.

He ripped the quiver off of his back. Chucking them across the hall. He spun in a circle, head lifted to the ceiling, hands clutching his hair.

"Kid…"

Roy looked at who spoke. An archer. A sandy haired man with a bow in his hand. The one who killed his brother.

"Murderer." The word had barely left his lips before he had slammed into the archer. Roy could hear people call out, he heard 'Clint', 'Hawkeye' and 'Speedy' shouted. He felt his fist connect with a nose, and a satisfactory crack. Hands gripped his arms, ripping him off the murderer. A red haired woman was helping the murderer up. "I'LL KILL YOU!" He cried, thrashing against the restraints."I'LL PUT AN ARROW IN YOUR CHEST! I SWEAR ON THE LEAGUE I'LL KILL YOU!"

AN) Aren't I evil? That was probably rushed, but thins will slow down. How the kids got into Marvel will be explained later. This mainly focused on Roy's grief, Wally's will be covered soon. Review! Review and more chapter will come soon!
