"So…the Donatello who I saw earlier is from a horrible alternate dimension where his family's dead and he killed Shredder?" April asked as she handed Leonardo an icebag.

"Yeah," Leo replied, gently applying the icebag onto his bruised jaw. "That's why he has all those scars on him."

"But that still ain't an excuse for him to act like a real jerk," Raph griped, scowling.

"Or beat us up like what he did earlier," Mikey added then shivered a bit. "Dude's crazy strong. And when I say crazy strong, I mean both strong and crazy."

His brothers hummed and nodded in agreement. April put a finger to her lips in thought.

"I don't get it," she wondered aloud. "Why is he here in our dimension in the first place?"

"Beats me," it was Raphael who answered as he got himself a glass of water, "he said something about our future being at risk and stuff like that. Bah! Whatever his reason is, he just barged his way into our family, kicked our shells and mocked us. Like I told you, a complete show-off!"

"Good thing Sensei was able to tell him off before he could beat us up further," Michelangelo sighed in relief.

"I kinda agree with you guys," April admitted, "but I feel sad for him. Still a teenager and he had to go through all of those bad things. I guess he had no other choice but to become an adult at once to take all of that in."

The turtles didn't respond, but the girl knew that she had hit the nail on the head.

"Whatever!" Raph waved off, walking away. "To me, he's still a bad vibe to this family. Now if you'll excuse me, I've got a monster truck rally to watch."

"And I've got a date with three slices of Ultra Cheese Pizza!" Mikey reasoned happily as he also skipped off.

April sighed rather heavily. Boys will be boys, even if they're teenaged mutant ninja turtles.

"Hey, April," she heard Leo call and turned to him. "If you're stuck in a situation like ours, what would you do?"

His human friend gave him a genuine smile. Well, at least one of the boys listened.

"I guess I would dig a little deeper," she said, placing a hand on his right shoulder. "I'd try to understand him better and respect him for what he's been through. You know what they say. Experience is the best teacher. And practically, Donatello's had a lot of experience."

The blue-masked turtle stared at her blankly for a moment, then smiled back, a sign that he understood her lecture.

"Thanks for the advice, April," he stated.

'Now I know why Donnie liked her…'

Raphael got out of bed early in the morning to answer the call of nature. He was trudging drowsily to the bathroom when he heard grunts of some sorts, followed by what sounded like whacking and thumping.

'It's freaking 2AM! Who the shell is up this early?'

He followed the noise to the dojo, careful to not make a sound. Sure enough, someone was inside, training in the candlelight which projected his shadow onto the sliding door. Raph observed the shadow as it kicked and punched the air.

'What? Who…?'

It was one of his brothers, Raph was certain, for the shadow had an outline of a shell on its back. Suddenly, the shadow brought out a pair of katana and began slashing at the air with it.

'Leo? Seriously? Can't he get a break or something?'

He was well convinced that it was the eldest training in the dojo when the shadow dropped its katana and armed itself with a pair of nunchaku.

'Huh? Mikey? Impossible!'

The red-masked turtle watched in awe as the shadow swung the nunchaku about and interchanged them into kusarigama. This went on, the shadow switching weapons every now and then, from heavy-looking clubs and maces to weirdly-shaped blades and even a pair of sai, making Raph wonder just how many weapons whoever it was in there had.

One thing was confirmed, though: The mystery turtle sure knew how to handle ALL of those weapons.

Finally, the shadow twirled about an all too familiar bo-staff. Raphael inched closer towards the sliding door.

'No way! Could it be…that jerk?'

A blade pierced through the sliding door all of a sudden, a few centimeters from the sai wielder's face. Raph yelped in surprise as he stumbled back. The shadow started to grow bigger and he heard footsteps coming his way from inside the dojo.

'Darn it! He's on to me!'

And without another thought, the turtle made a mad dash back to his quarters, completely forgetting his supposed trip to the bathroom.

After breakfast that morning, Michelangelo decided to take his time on the couch and watch a show on TV a bit. However, when he got to said piece of furniture, he saw an unexpected device on the cushions.

No, it wasn't the usually hard-to-find remote, but Mikey wished it were.

"Hey…alt-dimension Donnie's TSJ," he mumbled to himself as he took the gadget.

He examined it for a while, amazed that such a small piece of technology had the power to rip a hole in the fabric of space-time con…con…con-something.

'Wouldn't hurt if I take a look.'

Curiosity had him in its gnarled clutches as he turned it on. Instantly, the TSJ's hologram screen popped up and the youngest of the ninja turtles was soon scanning through the hundreds of files and folders the machine stored, choosing which he should look into first. That was until he came upon a suspiciously-named file.

'Ooooooh….File X. Wonder what it's about.'

With his tongue sticking out, he was about to press it when the TSJ was abruptly seized out of his hands.

"WHAT THE SHELL DO YOU THINK YOU'RE DOING?" Donatello screamed, holding his gadget close to his plastron.

"I saw it on the couch!" Mikey yelled back as he got on his feet. "Look, Donnie. If you don't want anyone looking through your private stuff, then keep it to yourself, not in where it's exposed for everyone to see and touch."

The alt-dimension brainiac turned to the TSJ cradled in his arms and gasped when he saw what Michelangelo had tried to access.

"STAY AWAY FROM MY THINGS, GAKI!" He shouted, walking back to his lab. "And it's Donatello, not Donnie. I ain't like your weak brother who's fond of nicknames!"

The lab door slammed shut and Michelangelo winced. Taking a look at the TSJ actually DID hurt. His eardrums were practically throbbing from the purple-masked turtle's shouting.

"What's going on?" Leo asked, he and Raph coming to their baby brother's side. "We heard yelling."

"Dudes," Mikey started, massaging his temples, "we gotta discuss about alt-dimension Donnie."

In the confines of his lab, Donatello was sitting in a corner with his knees brought up to his chest.

"They're beginning to get suspicious," he murmured to no one, his eyes narrowed.

He glanced at the TSJ in his hands. Its hologram screen revealed the contents of File X: A picture of a Japanese man in his late twenties with a big red "X" on it.

"But the turtles must not find out. They must not interfere with my plans," he whispered, staring at the picture with burning hatred in his burgundy eyes. "Almost time to start Operation X: Kill The Shredder."

A/N

No, Donnie! It's too dangerous! O.O

So that's what he's been planning all this time. But is he really strong enough to take down the Shreadhead of that dimension? I mean seriously, the guy's nastier than my mother when she's cranky! O_o XDD

Now, about me updating. Since it's already my Christmas break here, I'll probably update once every week. Twice if I can type up new chapters fast or if I'm in the mood. I'm a mood person. LOL

And since I have only two weeks of breaktime from school, expect some abnormal no-updating periods in two weeks' time. Yes, my school is that cruel.

Now I'm off to watch some Gintama!
