Red vs Blue is a long-running machinima series by Rooster Teeth that began in 2003, built from Halo gameplay footage and voice acting. O'Malley is the rogue artificial intelligence who possesses the medic Doc, turning a mild-mannered character into a scheming villain. His oblivion line, with its strange Red Bull comparison, became a favourite among fans because it captures that mix of menace and absurd humour. Shared on soundboards and reused in edits, it still works as a quick shorthand for a villain who is both threatening and ridiculous.
