Doominator

The Doominator is a huge robot that was set to destroy Wumpa Island forever. Cortex's plans was to build the robot and destroy Wumpa Island himself, but in the story Uka Uka replaced Cortex for Nina Cortex, then Nina kiddnapped Coco Bandicoot and brainwashed her into her building the robot while Crash and Aku Aku are searching for coco, coco is finished and the Doominator is complete Nina and Cortex are about to let the Doominator do its job. but right when hope is lost for Wumpa Island Crash reaches the main control room of the Doominator, crash then deafeats Nina and deystroys the the giant machinary. Coco returns to her normal self and uses the purple thingy (that Crash had all the time) to shut off the Domminator, the Domminator then falls and crashes on top of Wumpa Island. The remains of the Domminator are thought by some to be seen in the new game Crash: Mind Over Mutant.
