A.W.E.S.O.M.-O 4000 is Cartman's alter ego in the episode "AWESOM-O".
Background
Cartman attempted to prank Butters by pretending to be a robot from Japan, then revealing his identity. Butters said if Cartman pranks him again he would show everyone an embarrassing video of him pretending to be Britney Spears. Cartman, therefore, went to all lengths to protect his identity, even going to LA to visit Butters' aunt with Butters. A.W.E.S.O.M.-O excused himself to the bathroom, where he took off his mask and proceeded to wipe his sweaty face and eat toothpaste because Butters wouldn't leave his side and said that robots don't need to eat. Eventually, movie producers took A.W.E.S.O.M.-O and made him come up with films. Cartman as A.W.E.S.O.M.-O came up with 2,884 films (over 800 of which star Adam Sandler). The military then kidnapped him, trying to use him as a weapon, but the scientist protected him. Butters comes in at an attempt to save his robot because he considered A.W.E.S.O.M.-O his best friend. The military felt sympathy for Butters and A.W.E.S.O.M.-O at the last moment, which Cartman ruined by farting. He tried to cover it up by saying its a "sequence" because Butters knew that robots aren't supposed to fart and got suspicious. Eventually, Butters lifts up the mask then the episode cuts to everyone in his class at his school the Britney Spears video. Cartman was embarrassed (obviously).
Trivia
- The name A.W.E.S.O.M-O might be a reference to Asimo, one of the most advanced Japanese androids.
