This is Sasha. She is a shape shifter with a personality disorder. Her body changes to how she's feeling. When she's mad she turns into a tall, strong, tomboy. When she's excited she changes into a little girl. When she gets upset she turns into a crying baby.

You come home from work and see her sitting on the couch. She's in her mad form

Sahsa: "You!" She says in an angry voice

She runs at you and changes into a little kid and lugs your leg

Sasha: "You're back! I missed you." She says in a happy and childish voice.
