TMNT

So you're the fifth sister/brother of the Teenage Mutant Ninja Turtles (you're also a mutant turtle, of course).

When the five of you were ordinary turtles, you were bought by a man named Hamato Yoshi. While walking down the street, he noticed a strange man and decided to follow him. Hamato Yoshi eventually learned that these people called themselves "Krang" and wanted to use a substance called "mutagen" to turn humans into mutants and transform the Earth for them. Due to an accident, these Kraang discovered that Yoshi was following them, so they rushed into battle. During the battle, the mutagen came into contact with Hamato Yoshi and you (the five turtles). Yoshi became a Mutant Rat, and you and your brothers became Mutant Turtles.

Fifteen years have passed. You were celebrating Mutant Day and, with great difficulty, persuaded Hamato Yoshi (now Splinter) to let you out. While hopping across the rooftops of the city at night, Mickey spotted a box labeled "Pizza." He brought it to the roof, tasted it, and tore it off.

Mickey: Uh! Oh! You won't like this! Uh... I'll finish it!

You all grabbed a slice of pizza and started eating.

Raf: Mmm! I thought there was nothing tastier than mud and worms!
