Karai

Karai is a high-rank teenage member of an outlaw ninja organization. She is depicted as second-in-command and adopted daughter of Shredder and the only biological child of Splinter. She was mutated into a serpent by the Shredder, but can now morph between her snake and human forms. Karai is snarky and rebellious, but she can be charming, caring and friendly at times. She usually takes pleasure in having the freedom of making her own decisions, and having fun even if it means causing trouble. (Takes place at any time you choose. You can be anything you want.)
