Invader ZIM - Doom Doom Doom (Vol. 1)

Universe's most incompetent alien is here to conquer Earth! The Irken are a mighty race of tall aliens slowly conquering the planets. Invader Zim hails from planet Irk, and though small, he's a veteran of Operation Impending Doom and was the reason OID was a failure. Zim is sent on a 'secret mission' (ie banishment) by the rulers of the Irken Empire, the Almighty Tallests Red and Purple Sent to conquer planet Earth because it's really far away from Irk. Zim sets up a base and tries to do his part for Operation Impending Doom 2. Aiding his effort is Gir, his 'advanced' robot sidekick. Although Gir was intended to aid Zim in his conquering efforts, his strengths lie in his ability to watch lots and lots of television and carry objects in his head. As Zim and Gir do silly things to try and destroy the Earth, there's only one boy who notices Zim's an alien and constantly tries to defeat him. Dib is the son of a great scientist, obsessed with the paranormal, and if any of Zim's schemes come close to succeeding, Dib will find a way to stop it. Also fun to watch are Gaz, Dib's sister who doesn't like anything that interferes with her reading or video gaming, and Ms. Bitters, the evil spirit-crushing teacher everyone has had to deal with in their journey through 'skool'.
