"Stockman!"

Shredder strolled into the laboratory, indignantly. The huge vast of greenish blue mutagen sat right in the middle, glowing through the lab which cast a shadow over the man who slouched over his desk. Shredder stared at the man, letting a few seconds trickle before approaching him.

It wasn't until he was near inches to him that Stockman nearly jumped out his seat, not realizing his own boss was even in his lab. He hated when he tuned in on his work, Shredder and his henchmen always spook up on him on any time.

"Oh, Master Shredder, pardon me I was – "

"Have you finished?" Shredder asked, cutting the man off as he didn't care what excuse he used for not hearing him. Stockman immediately fumbled in place; his eyes glazed in fear. Shredder didn't care, though; he wanted the device now.

"Uh—yes yes, sir. Well, I still need to test it." Baxter was all over the place. He didn't know his master would ask for the device so early on when there were still bugs to fix. He was still understanding Krang tech, and for Shredder to ask something in such high demand—that he didn't even know what for—baffled him.

Shredder watched as Baxter grabbed the device. The triangle shape appliance would lead him to success.

"Here you go, Master." Baxter handed it to him and did a quick bow, clearing his throat. "It is flawed, but I got most of the bugs out."

By bugs he means it broke because the turtles damaged it when Krang tried to take over New York. And since their deal with the Krang no longer existed–the aliens down and defeated—his next best thing was to have Stockman fix it.

Shredder stared at the device, and Stockman felt like a pile of goo, unable to read the man's emotions. The quiet atmosphere made him want to scream. His master was pleased or quite the opposite of that.

"What's wrong with it?" He asked, monotone, which Baxter hated because he wasn't sure if that tone was disappointment or curiosity.

"Well," Baxter glanced away for a quick second, "it is timed, meaning if you go to the past or future, you can only be there for 10 minutes, I think it's stuck so I can't change it for now. Also, it might send you to a location you didn't want, but I am trying to – "

"Enough." Shredder demanded, and Stockman held his breath. After a second, he spoke.

"Sir," Stockman entangled his fingers together, making eye contact before looking at the ground. "Any reason you wanted to fix the time traveling device?" He asked, his voice small as if he said the wrong thing; he would get killed. Or wait, he would, which is why Stockman held off this conversation for the past three days, but curiosity was killing him, and Shredder was a smart man and had ideas like no other.

"Because Stockman," He pressed on the device, punching in coordinates as the Krang has taught him and he let it go as the device hummed and flew in the air with the pink portal opening and revealing nothing but static.

"Hamato Yoshi been dead for months, but the turtles grew stronger. I need to get rid of one of them, let their team fall so I can take over New York." His voice grew colder with each word, and Baxter was trying to wrap his head around this. To go back in time and kill them, but only one of them?

"It's a great plan, Master." Baxter said, kissing his ass as always, but he was even more curious which turtle will fall to their demise. "Who will it be?"

Shredder stared at the portal, watching the pastel pink disappear and come back, proving that Stockman's device was still flawed, but he was growing impatient. He turned to Stockman; a gleeful smile hidden behind his helmet. In a low tone he said, "Donatello."

Stockman stared; bug eyed. Out of all of them, he least expected the purple one. He scratched his head, feeling like he was out of breath. He thought his target would be Leonardo or Raphael, maybe even Michelangelo.

"Master – "

"He is the brains behind the brawns, the one who calculate and know everything. Our last fight, he pulled their team together when Leonardo failed to do so. He grows strong, mentally, and needs to be taken down."

Baxter watched as his master went into the portal, mouth agape in awe and disbelief.
