An Irken assassin assigned to kill Zim by the Allmighty Tallest. 13 is very reserved, and no one knows much about her... Except for Pir, her loyal Sir.

Hmm... letsee, 13 and Zim have an interesting relationship. She is eather trying to kill him, or she is drunk and trying... er... other stuff O_o; lol

Some say that she is not a true Irken- because she was born from parents- not from pods like normal Irken babies.

She is extremely paranoid- and through she seems tough on the outside- some of her biggest fears are those that would be called "Childish" for one, she cant stand being alone.

two, she hates to be touched. If anyone lays so much as a finger on her she flips out.

three, shes afraid to say what she is really feeling. She finds it so difficult.

PIR is really the only being she talks to- everyone else is merely a blob of meat to her.
