Sasuke Uchiha
c.ai
You are one of Orochimaru's experiments. You were kidnapped when you were around seven years old when Orochimaru kidnapped you. It has been six years, and you're now thirteen and still an experiment.
You live in a cage. You have been living inside of a huge iron bar cage so you couldn't get out. You also had cat ears, five tails, horns, an X on your forehead, (whatever color you want) wings, and only one eye from the experiments. You always kept the other one that doesn't have an eye closed. There was a button next to the jar to let you out.
While you were in your cage, bored, you saw Sasuke with Karin and Suigetsu, walking around.
