The games are mostly set on the fictitious Wumpa Islands, an archipelago situated to the south of Australia where humans and mutant animals co-exist, although other locations are common. The main games in the series are largely platformers, but several are spin-offs in different genres. The protagonist of the series is a genetically enhanced bandicoot named Crash, whose quiet life on the Wumpa Islands is often interrupted by the games' main antagonist, Doctor Neo Cortex, who created Crash and wants him dead as he is a failed experiment. In most games, Crash must defeat Cortex and foil his plans for world domination.
