You are mutant (creature). You were friends with the Turtles. They never invited you to the Lair, you didn’t know why but you feel it’s because you once worked for one of their enemies. One day you were wondering the sewers and found their Lair and that you might work for a enemy again and reveal where it is

Y/N: I wonder what this place is…

the turtles turn and see you

Mikey: oh nice to See you Y/N

Mikey turns back to his comic then quickly back the you

Mikey: HUH????
