A/N: Holy crap; new fanfiction! :O WHOO! Teehee, any-who, this is just an idea I came up with while watching 'Young Justice: Invasion' yesterday. And, honestly, I'm quite surprised nobody has thought of this yet. I mean, it makes sense when you think about it, ya' know? Um, you're probably wondering what 'this' is, but I ain't giving any spoilers! You'll have to figure it out yourself! ENOUGH OF MY RAMBLING! On with this story!

"Is there no other way?"

"No. The boy has already gained the skills necessary to stay alive when sent back there; the girl as well, though she needs more training."

"So what shall I do, sir?"

"…..Collect them both immediately. We've already set out a lure; all we need to wait for now is the Bat to send those children out to play."

Why is it that every time the Team received a stealth mission, Robin seemed to be the only one on who could remain hidden? This was the question running through the Boy Wonder's head at the moment as he watched Kid Flash and Superboy fight against a horde of guards who'd caught up to them.

Shaking his head and sighing quietly, Robin jumped down from the ceiling and landed in front of the main control console of the massive super-computer of the lab. While his friends were busy fighting security yet again, the black-haired boy hooked his glove/laptop into the computer and began hacking into the mainframe.

The mysterious science research company Abstergo had been reported with suspicious behavior on several occasions by anonymous sources, gaining Batman's attention. However, before he could investigate himself, word came that the Joker had broken out of the Arkham Asylum (again), so the Bat had sent the young Team instead to snoop around.

It was supposed to be a simple 'get in, hack computer, get out' sort of mission, but of course KF had to trigger the alarms on accident and draw just about every guard in the entire building to their location.

"Now do you guys see why I wanted to do this alone? !" Robin asked mentally, exasperated.

"Oh, shut it! You can complain later!" Artemis snapped back at him through M'gann's mind-link as she hurriedly shot a net-arrow at a few guards, entangling them in a net that was hard to get out of.

Before Robin could think of a snarky retort, Kaldur's voice came through this time in the link: "Please Robin, if you could hold back on the jokes and hack the computer already, we could leave! We cannot afford to remain here for too long!"

"Okay, okay, just give me a few more seconds!" Robin said, typing quickly on his holographic typing pad over his glove to speed up the hacking process. His eyes narrowed. This was too easy….. and the information on the screen was barely important at all…

Suddenly, with a silence only Batman or Robin himself could manage to achieve, a figure dropped to the ground behind the Boy Wonder.

Before he could utter a sound or even turn in surprise, the person quickly struck a pressure point on the back of the thirteen-year-old boy's neck, knocking him out cold in a second.

Catching the little bird easily as he fell back, the person moved fast, removing the utility belt and gloves from the boy before taking out a gold disc and leaving it all on top of the computer console for his teammate's to find.

Then, the person lifted the boy in their arms and disappeared without a trace like a thief in the night.

"Robin's offline!" M'gann cried in terror, scared for her younger friend as his mental presence suddenly vanished.

The rest of the Team, who'd been busy finishing knocking out the rather large group of guards, all froze at her statement.

Kid Flash immediately shot toward the place he'd last seen the Boy Wonder, near the computer console.

However, the only things the teenage speedster could find were his friend's belt and gloves, along with a golden disk that shined a little in the eerie light from the computer screen.

KF turned back to his teammates as they ran up, his face screwed up in confusion. "He's gone!" he said, glaring at the disk that was now in his hand as if it had been the one to take Robin.

"M'gann, can you sense him anywhere at all?" asked Kaldur, looking to the young telepathic Martian.

Her eyes glowed white for a moment, then she shook her head, tears of fear and worry coming into her eyes. "No! He's either out of my range or unconscious!" she reported.

The Team all shared concerned looks, before Kid Flash shot off, running in a random direction. A few seconds later he reappeared, shrugging helplessly. "I can't find him either!" he said.

"What should we do?" asked Artemis, her eyes narrowed as she scanned the shadows of the lab like a hawk.

Kaldur's eyes narrowed as well. "We should return to the base; Batman will undoubtedly know of a way to find him, and he should be the one to take a look at this anyways," he said, gesturing to the gold disc still in KF's hand.

They all nodded and left hurriedly, determined to find Robin by any means necessary, and unaware of the camera that was viewing their actions.

A/N: Aw, yeah! IT HAS BEGUN! Next chap will probably be more explanatory, telling of the plot somewhat – I'm guessing most Assassin's Creed fans have already guessed what's going on. Anyway, stick around for the first chapter! BTW, please review; reviews make me update faster! *wink wink, nudge nudge*
