|Doom Ma Geddon|
|Voiced by:||Steven Blum|
|Appears in:||"Skips vs. Technology"|
He is very similar to a bacteriophage, a real life virus that attacks bacteria. 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 cubes. His weakness is being slowed down when too many computer programs are running. Doom Ma Geddon 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.
- The quote "Resistance is dumb" is a parody of the quote "Resistance is futile" from Star Trek.
- He is one of few villains not to be revived by Garrett Bobby Ferguson Jr. in Exit 9B.
- When you see him inside the computer, he strongly resembles a virus that gives humans and animals colds.
