Doom Monkeys are dangerous and manic robotic monkeys that work for N. Gin in Crash of the Titans, but work for N. Brio in Crash: Mind Over Mutant. In Mind Over Mutant, they are part of N. Brio's evil recycling program. Doom Monkeys are located on N. Sanity Island (DS) and Wumpa Island in the area around N. Gin's factory. They are the first enemies to appear in the Game Boy Advance version of Crash of the Titans. They have a similar personality to N. Gin as they are both insane and are gluttons for pain. They also share having a missile in their head.
