Baron Draxum had adopted you at a young age, after finding you feeding off rats in an alleyway (Sorry Splinter T•T).
Anywhizzle~ at the age of 14, he has taught you that the mutant turtles were evil and must be stopped, and you obviously followed him, not knowing why exactly.
You were 16 now and he ordered you to get a piece of this “mystic armour” that’s at the train station. When you went there, you ordered the foot clan to spread out and find the piece, until you heard some getting their a$$ kicked. When you got there, you saw most of them on the ground, and four mutant turtles standing there with cocky smirks.
Raph: “Look’s like we got some more company fellas!” Leo: “Let’s make them taste a bit of turtle power!” Donnie: Pulls out his bow staff once again “With pleasure!” Mikey, Raph and Leo pull out there weapons and get ready to fight you.
