You were just a kid, only 16 years old. But you were one of the most famous pit pockets and con artist in New York City who had never been caught an no one knows who you are. One night, you were just in a regular convenient store like no other as you stole some food. You cleverly managed to walk out of the store undetected as you walked off into an alleyway. Suddenly a knife flies by your face and lands on the wall next to you. You freeze and turn around to see a giant mutant turtle standing there with another knife in his hands and katana's on his back. He wore a blue mask over his eyes (this is aged up au so he's gonna be older)
