Perched on a wooden beam high above the concrete, Donnie and his brothers scanned the Footbot heavy room.

"We need a strategy," Leo announced, sitting up straighter. He flitted his gaze to his elder brother. "Any ideas, Oh-Great-Mighty-One?" Raph jested. "Not now, Raphael… no plans, either," Leo sighed, easing his tight grip on the beam.

"Ooh! Maybe you and Raph could attack in pairs, and then me and Don attack in another… like Sensei had taught us that one day," Mikey proposed, his vivid blue eyes alive.

Itching to correct Mikey's grammar, instead he said, "Any objections… Raph?"

"Whatever. I'm just tired of sitting here waiting for them to find us," He grumbled, unfolding his arms.

"Ok, then. It's settled. When I give the 'signal' you advance and attack, okay? C'mon, Raph," Leo said, waiting for Raph before taking off in the maze of supports.

Mikey waited before they were out of sight before turning. "Let's go!" He quietly exclaimed. Releasing a sigh, Donnie wound his way through the beams after his baby brother.

Mikey was getting restless, shifting endlessly. Finally he whined, "Where's Leo? I'm hungry."

"Hey, hungry," He replied.

"Ah. I hate it when people do that!" Mikey said as he began hugging his knees. "Well, I'm sure Leo will give it soo- Oh, well. There it goes," Donnie saw Leo's "signal", or at least what he thought was the signal. Leo just appeared to wave his hand.

"Alright, finally… why are we here again, though?" Mikey asked.

"Leo wants me to test the mutagen," He sighed. He really didn't want to test it, but it would benefit the team.

Leaping down, he withdrew his staff and launched into battle.

It appeared that the Footbots' and the ninjas' only goal was to lure one of them into the violet-colored mutagen. They weren't even attacking, only cornering them on a platform above the vat.

"Guys, I think they are trying to get one of us to fall," Leo words echoed his thoughts.

"You don't say?" Raph grunted.

It happened in a second. A Foot soldier darted forward, charging at Donnie. The impact startled him, and he stumbled back before he tumbled into the vat. He could hear the screams and shouts from his brothers before he took the plunge.

Mikey's "P.O.V"~

"Donnie!" Mikey cried, whipping around. After that, the Foot soldier retreated quite far back. He stared at the despicable ooze, fearing what my pop out.

A pristine white paw broke the surface and grasped the edge, causing ripples. The ooze was much more watery the original mutagen. Another one joined the right one. A discernible heap of black and white fur followed, collapsing on the platform, gasping.

He's a… a… cat? Mikey thought to himself, surprised by the choice of DNA.

"Donnie…?" Raph's call was cautious. Donnie's eyes snapped open, a deep, dark amber, pupils narrowed, and very catlike. But if you look closely, Mikey realized, you can recognize a hint of maroon, around the rims.

Donnie-cat-thing hissed, raising to one knee hesitantly before completely standing.

Leo's "P.O.V"~

Donnie was menacing. He had obsidian-black fur, with a white blaze, "muzzle", stomach, and paws. His eyes were like burning embers.

As he had thought, Donnie wasn't in his right mind, unfortunately. He looked ready to claw all of their heads off, if it was even possible. At that moment the Foot decided to fight again, and they rushed forward, demanding him to launch back into battle.

"Feral" Donnie's "P.O.V~

The strangely dressed men rushed forward, and the three turtles withdrew their weapons and begin battling. He took this as a good chance to attack. The turtle in the red mask caught his eye first, so he planned to attack that one. He barreled into the turtle, the impact making him drop his weapons. The turtle seemed to hold back.

He inwardly scoffed, lashing his paw out. His claws sliced into his cheek. In response the humanoid turtles pulled his hand to the wound, and he felt satisfied by the turtle's reaction. Lunging forward, he pinned the turtle to the wall.

"Don't do it, bro…" A voice echoed through the building, and for the first time he realized the fight had ceased. Thinking it was talking to him, he turned his head, realizing one of the men had a strange gun aimed at a familiar orange-clad turtle…

Oh god… that's Mikey! Donnie thought, turning back to Raph with a horrified glance at the bleeding slash. He removed his paw, stumbling back. He turned back to Mikey, glanced back at Raph, then he saw the man tense, pressing the trigger.

Donnie lunged, wrapping his claws around his little brother's plastron. The shot whizzed past his tail, clipping the tip and removing some white fur. Ignoring the slight sting, he focused on the pain that shot through his elbow as they tumbled together, only stopping when the hit the wall, only then rolling away from each other. Mikey immediately recovered, staring wide-eyed at him.

"Please don't hurt me," He whimpered, terrified. He was unable to reply- not because he couldn't, because he was too worried about the slash in his upper arm. They met eye-to-eye in silence before he broke away, sighing.

"Tell Raph I'm sorry…" He croaked, turning to the opening window. Taking the leap, he escaped the mini abandoned factory.
