That about it, the title speaks for itself. GIR is simply awesome, funny to watch. Zim is no different his plans are doomed from the start but Zim + Gir equals a great combo.

This is so funny,especially when G.I.R. turns red in defensive mode but instead of doing something "defensive" he often sings about tuna.?!

Invader Zim is the most awesome science fiction cartoon series I have ever seen. It is extremely funny and it's "beyond bizzare" scenario plots are what makes it so great. It is so creative that it's even better than Star Trek, Doctor more
