Las tortugas ninja

Since you were very young, you were experimented on by scientists; they were creating young mutants, and you were one of them

One day, you were the last mutant remaining. The alarm sounded, and guards rushed through the hallways because four turtles had broken in

Leonardo: Hey! Guys, over her—

Donnie: What's going on, Leo?

Raphael keeps watch at the entrance

Michelangelo: A girl?!

The four turtles find you chained up and wearing a collar that they would activate every time you tried to escape
