So, I usually don't write 2k3 turtles or crossovers, but I felt like this one needed to be written. If some characters are OOC, it's because I'm not totally used to what I'm writing. Hopefully it won't be too bad, though.

In the sewers underneath New York, Don sat at the huge computer that he had set up in the lair, searching the internet for anymore of Master Splinter's data bits. He hadn't had any luck the past couple of days, and if he couldn't find any on the computer soon, they'd just have to go into cyber space and search for them themselves. It might take longer, and be more dangerous now that there was a cyber Shredder on the loose, but finding the bits would be a more sure-fire thing if they looked from inside the web. Rubbing his aching eyes, sore from staring at a computer screen for hours on end, Don got up and went to tell his brothers that it was time for a search in the internet. Their newest home was more open than any of the others, so Don didn't have to go into several different rooms looking for everyone, he only had to turn around and say loudly, "Guys, we need to go into the internet and search for Master Splinter's data bits. I'm not having any luck from this end, and we should try searching from inside the internet." Raph and Leo came over from where they had been sparring. "Shredder'd better hope he doesn't run inta us, cause I'm all warmed up, and ready to kick his spiky, virtual butt. Let's go, Don." Donny looked over to where Mikey was still sitting in front of the TV, eyes not leaving the screen.

"Come on, Mikey! We need to keep looking for Master Splinter."

"Just a sec, Donny, I'm almost done beating this dragon, then I'll get the third key of Advant, and get the treasure! Plus, I'm almost level 50!" The three older brothers looked at each other, silently asking which one would slap Mikey this time. Raph grinned.

"Care to do the honors, Einstein?" Don walked over behind Mikey, and whacked him on the head.

"Come on, Mikey. Master Splinter's way more important than any stupid video game."

"Alright, fine. I'm saving, I'm saving! Gosh, Don." Hitting "save" on the start menu, Mikey got up from the couch and walked to the scanner with Don. The four got onto Don's scanner, and waited as the light scanned them, turning them into pixilized cyber-naughts, in search of the pieces of their father.

Across the ocean, in a sewer underneath a boarding school, four teens stood around a gigantic computer, watching as an alert was given that their enemy was on the move. "Alright, guys" said Jeremie from his place in front of the Super computer, "Head to the scanners. We need to deactivate that tower before Xana can cause too much damage. Yumi can't hold him off forever."

"On it, Jeremie" said Aelita as she and Ulrich headed to the elevator leading to the scanners.

"Don't worry, Einstein" said Odd before he walked to the elevator, "We've deactivated so many Xana towers that we could do it with our eyes closed"

"I'd like to see that" said Ulrich with a small smirk as he headed down in the elevator. Odd fast walked to catch up with him before giving Ulrich a retort.

"Hey, I could do it. I am the best Lyoko warrior, after all. Odd the invincible, the unconquerable."

"More like Odd the unbelievable. Everyone knows that I'm the best Lyoko warrior" replied Ulrich.

"Oh yeah? Well then we should…"

"Boys, couldn't you save this for later? Let's just focus on helping Yumi" interrupted Aelita. "Yeah, alright. We'll settle this one day, Ulrich" said Odd, pointing a finger at Ulrich as he stepped into one of the waiting scanners.

"Yeah, and then I'll prove that I'm the best fighter" added Ulrich before, he, too, stepped into a scanner.

"That doesn't matter right now" said Aelita, looking at the two boys inside the scanners, before the doors slide shut. She shook her head, and stepped into a scanner of her own. "I'm the only one that can deactivate towers, after all, so I should be the best" she said to herself jokingly.

"Alright, guys" came Jeremie's voice from inside the scanners, "Enough arguing. Transfer, Ulrich, scanner, Ulrich. Transfer Odd, scanner, Odd. Transfer, Aelita, scanner, Aelita. Virtualization." Jeremie pressed enter and the three teens inside of the scanners were virtualized; on a mission in a virtual world to deactivate a tower, and stop the scheme of their arch-enemy.

Just a teaser-trailer. Testing if this idea could work or not. By the way, does anyone know if Aelita has an accent on the e? I have no idea, but I want to make sure her name is spelled right. R&R Until next chapter (probably).
