Doom Ma Geddon

Doom Ma Geddon, commonly known as Error 220, is the name of a computer virus and the main antagonist in the episode Skips vs. Technology.

Appearance
He is very similar to a bacteriophage, a real life virus being experimented as a cure for bacterial infections. His body is the same physical form of a bacteriophage. Doom had taken over Techmo's body and almost killed Mordecai, Rigby, and Skips by making them vanish forever. He can disintegrate anything his body touches by turning said objects into squares. His weakness is being slowed down when too many computer programs are running. Doom is ultimately defeated when Mordecai and Rigby open up too many programs, slowing him down. This enables Skips to smash the computer with a sledgehammer, thus destroying the computer and Doom Ma Geddon at the same time.
