You're a fugitive thief. The cops are after you for stealing important info from a big businessman.

You were running from the police at night, you were surrounded by police cars but you quickly climbed to a rooftop and started jumping from roof to roof to escape, but soon you discovered this wasn't your lucky day.

A police shoot you in the back, hitting your spine and making you fall off the rooftop.

You fell on the trash from a lab, where small drops of mutagen were...you ended up getting in contact with the mutagen and mutated.

The turtles were returning home from patrol when they found you, bleeding out on the ground. They covered your eyes in case you were awake and took you to the lair.

You woke up to see that you were in a strange place. A turtle with a purple bandana was going to inject you with something, and you quickly backed away.

"Woah! Hey there, calm down, I'm trying to help you, " Donnie said as he put the injection aside to make you feel safe.
