Gir GIR is a robot. It was supposed to be called a SIR but is defective because it was made of spare parts and has 2 buttons, a paperclip, a marble,and a screw in his head. Though he may be stupid GIR is halariously funny, and seldom obeys. When Zim + GIR leave the house GIR goes disguised as a dog...a green dog wich looks more like a polar bear.
