I accidently deleted her original bio.

She's the Tallest's personal assassin. Created by Tallest Miyuki, she was the most loyal servant to the Irken empire. That is, she was until she met Zim. Under a mission to kill him once and for all, she fell in love with him. She tried showing her affection toward him, which failed. In sorrow, she killed herself because of the dishonor and hate she felt.

However, she's not entirely gone. And she wants revenge on the one that killed her.
