I find it funny that Gir became a cute merchandise icon when in the show and comics he’s probably one of the more horrific characters on there. Like yes he’s very cute but Gir doesn’t have any morals and has killed multiple people on occasion. The world is his sandbox and the people around him are at the mercy of his whims.
Canonically only held back from killing zim and conquering the earth himself by the mental fog of continuous malfunctioning. Still allegedly ate a baby once.
