So while the teacher was talking and talking and talking very enthusiastically about educational stuff, random ideas started forming in my head.

I was thinking, what if the turtles were replaced by their voice actors? Like human?Yeah they are technically voicing the turtles, but like, it's like...uh...maybe I should give an example.

Yes and just in case you don't know the voice cast of TMNT season 4:

Leonardo - Seth Green
Raphael - Sean Astin
Donatello - Rob Paulsen
Michelangelo - Greg Cipes
April - Mae Whitman
Casey - Josh Peck
Fugitoid - David Tennant

All of them are human (because it's their voice actors) and probably around the age of the turtles/April/Casey. And they also have the same attributes and personalities as the turtles/April/Casey. Not everything is accurate, apologies. Check it out below.

Season 4 Episode 1 (Beyond the known universe)

Seth stared out of the window. The area which was once filled up by the Earth was now replaced with the black hole that swallowed his home planet whole.

"Captain's Log," He said in his mind and sighed, "Star date? No idea."

"The evil Triceratons, a race of aliens from across the galaxy, invaded earth. They wanted to wipe out their ancient enemy, the Kraang, so they unleashed a black hole weapon that destroyed both the Kraang and their secret hiding place, Earth."

He paused before continuing to narrate to his imaginary audience in his head, "We lost our friends, our allies, even Master Splinter. We were only saved at the last second by a mysterious human called the Doctor."

The Doctor, as he calls himself, punched in a few keys on a computer control panel and glanced up at the people he saved. With a worried look on his face, he walked casually towards the giant window screen Seth was staring out and touched the screen.

Seth couldn't take it anymore.

"All right, Doctor, or whatever your name is, what just happened?"

His sudden outburst provoked Sean, who hadn't said a word since they left Earth. Sean yelled, "This has got to be some kind of sick joke, right? Right?"

Slap! The Doctor's hand made contact with Sean's face. As the Doctor walked away, Sean gave a 'what the heck' look at Seth. Unknowingly, Greg was behind him, trying to hold in his laughter.

"Calm down, Astin," The Doctor said, "First things first. I have a job to do." He hopped into what seemed like the 'wheel' to his ship.

"Now, please, I've got a ship to fly while you all stand about gawking."

"That's not good enough," Mae said, annoyed in a way that their mysterious savior was ignoring the fact that they had just lost everything. Couldn't he be a bit more sensitive?

"Where are you taking us?"

The Doctor sat securely in his captain's seat, "All questions will be answered in time."

He clicked on a few buttons, resulting in the ship powering up. As the ship's hum grew louder, the Doctor smiled widely, as if he had accomplished something. He warned, "Hold on to something!"

The ship started flying faster and faster, soon, it was so fast that it felt impossible to hold on to just the floor they were standing on. Screams from the group of 6 grew louder as the ship flew at a speed so high that the visible space that could be seen from the giant window screen was replaced by a large range of vivid colours.

Realizing that his warning had came a little too late, the Doctor apologized with a sheepish smile on his face, "Oh, oh, too late for that. Apologies."

Greg, who could no longer feel his face from the huge vibrations, shouted through the screams and chaos, "Not cool bro!"
--------------------------------
The ship slowed down and soon, it stopped just in front of...the Earth?

"What...what just happened? We're actually alive?" Sean questioned as he checked to see that all four of his limbs were still intact.

Rob ran towards the giant window screen, noticing the presence of the Earth just in front of them. His quick thinking realised something.

"I think we...we went back in time," Rob said, observing and pointing at the position of the Earth, "About six months, based on where the Earth is in its revolution around the sun."

"Six months?" Seth's face lit up, "Then that means everyone's back? Including Master Hoon Lee?"

"Yes, Seth, but only for six months, and then, the Earth is doomed once more," The Doctor explained as he hopped out of his seat, "Apologies."

"I get it," Mae stepped in, "We stop the Triceratons before they ever get a chance to use the Black Hole on Earth."

"Indeed," The Doctor said before starting a long explanation. He moved closer to the giant window screen.

"The Triceratons are spending this time searching the universe for the three fragments of the black hole weapon."

He tapped the screen, the screen then displaying the black hole generator broken into three.

"Many years ago, the Utroms broke the machine into three pieces, hiding each fragment in the safest parts of the galaxy they could find."

His face turned serious, "We must find them before the Triceratons find the fragments and reassemble them."

"And if we mess up," Greg had his happy face on, "We just time travel back, right?"

"No, no, no, no. A Black Hole prevents repeated localized time travel because even time is subject to its attraction," The Doctor said as his hands made a few gestures.

"If we fail, Earth is lost forever."

Everyone's face turned serious, realizing how dangerous their mission was.

"But on the bright side," The Doctor smiled again, "Whoever gets a second chance?"

Josh leaned against a space pod like structure, "So why do you care, human dude who doesn't live on Earth? Why are you helping us?

"Yeah. Who are you anyway?"

The Doctor cleared his throat, "I'm the Doctor."

"Doctor?" Seth repeated, "Doctor who?"

"Just the Doctor," He confirmed, "Or you can call me by my human name, John Smith, or David Tennant, but I use John Smith more often."

The group shot glances at each other.

"I'm a friend to the Utroms. It was Bishop who sent me. And, plus, I've always wanted to see Earth!" The Doctor said enthusiastically.

Rob gave the Doctor a puzzled look, "What'd you mean, human name?"

"Oh yes!" The Doctor exclaimed, "Have I mentioned that I'm an alien?"

He whipped out a stethoscope from his trench coat. Grinning, he said, "Observe."

Motioning for Greg to come closer to him, he handed the stethoscope to Greg and got him to place it on two different locations on his chest.

"Whoa..." Greg's eyes widened, "He has two hearts!"

"What?" Rob blinked twice, "That's impossible!"

"It is when you're an alien," The Doctor said, "I'm a Timelord."

"Timelord? That's a kind of alien?" Mae asked, receiving a nod from the Doctor.

"Dude, I wish I had two hearts like a Timelord!"
------------------------
Ok that was weird. And a little screwed up. But kinda fun to write. Sorry about not putting David's name, I just thought Doctor was more like it :p. And the last part is probably not as accurate because I couldn't fix the loopholes, or whatever you call it. The Doctor isn't a robot.

So...what cha think?

This is just a one time thing, wrote it for fun :)

Time to watch the new episode of TMNT!
