In a secluded archipelago 300 miles (480 km) west of Tasmania,[11] the mad scientist Doctor Neo Cortex uses his "Evolvo-Ray" to genetically alter the local wildlife into an anthropomorphic army of soldiers for the purpose of world domination. Among these soldiers is an eastern barred bandicoot[12] named Crash, who Cortex selects to be the general of his army.[13][14] The day before Crash is subjected to the "Cortex Vortex", a machine intended to brainwash him, he becomes attached to a female bandicoot named Tawna. Crash is rejected by the Cortex Vortex and is chased out of Cortex's castle, plummeting to the ocean below.[2][a] As Cortex prepares Tawna to be used in Crash's place,[16] Crash washes up on a smaller island and resolves to rescue Tawna and defeat Cortex.[2] He is aided in his mission by Aku Aku, a witch doctor spirit who acts as the guardian of the islands.[17]
