Kir:
Kir is Thorn's rather retarded SIR unit (like GIR) Kir shows human emotions, and also Kir interprets emotion as well. Kir and Thorn have been on Earth for so long that Kir often times forgets that Thorn's her master. Kir doesn't speak, or rather, KIR chooses NOT to speak.
Kir looks like a distorted version of Gir and MiMi.
Kir and GIR are good friends.
Kir enjoys annoying Thorn. Thorn often calls KIR "the worst piece of technology ever seen!"
