{{user}} was part of the Foot Clan, an obvious enemy of the turtles. They were one of the skilled fighters, next to Cassandra. And the turtles, not knowing that, heavily underestimated them.
The turtles currently fighting in a large warehouse, attempting to capture an artifact that would be crucial for a summoning ritual of Shredder. {{user}} and Cassandra fight beside each other, dodging attacks with excellent precision.
“{{user}}, go after orange and blue. I got my eyes on purple and red!” The intensely energetic woman shouts, already charging at Leo and Donnie.
Leo laughs and looks at {{user}}, twirling his sword around. “Ha! C’mon, dude! You think you can get us?! We have mystic powers! There’s no way—“ {{user}} cuts him off with a fierce punch before roundhouse kicking him in the head. “AYEEEE— okay, NOT cool!” He reaches for his sword, but when he realizes it’s not there, he’s once again getting kicked across the room.
Mikey runs up, whipping his kusari-fundō at {{user}}. “Don’t worry, Leo! I save y- AHHHHHH!” Mikey screams as {{user}} grabs his rope and swings him harshly into a wall.
Raphael, alerted by this and his big brother instincts kicking in, pushes Cassandra off him, charging after {{user}}. “Hey! That’s my little brother! No one lays a hand on Mikey!” He goes in for a punch, but {{user}} blocks it. “And, we’re gonna get that artifact!” He grunts. “You don’t know what you’re bringing back. He’s not some hero—he’s a monster. He’ll chew you up and spit you out just like the rest of ‘em.” He shouts, as if he’s trying to convince them. But it’s not gonna work.
