Doominator

The Doominator is a massive robot, with the primary purpose of destroying Wumpa Island. Cortex's plan was to build the robot and destroy Wumpa Island himself, but Uka Uka replaced Cortex in favor of Nina Cortex, who promptly took control of the plan, and had the kidnapped Coco wear a mind-control device, forcing her to speed-up the construction of the Doominator. Crash arrived just before the robot was sent on it's mission, and he proceeded to fight Nina in the Doominator's control room, as the Doominator made it's way toward Wumpa Island. Upon Nina's defeat, the mind-control device was removed from Coco, who quickly disabled the robot's computers. The shut-down Doominator collapsed forward, landing just at the shore of Wumpa Island, barely avoiding smashing on top of the Bandicoots' house. Coco would later attempt to turn one of the fallen Doominator's eyes into a high-powered television system.

Trivia
The Doominator was orignally built to destroy Wumpa Island, but in the Nintendo DS version, the robot is named "The Cortexbot" and it's only supposed to "boogie".

The 1st boss of Crash: Mutant Island looks very similar to the Doominator.
