 As seen in Crash Bandicoot , Crash was once an ordinary eastern barred bandicoot before he was snatched from the wild by Doctor Neo Cortex and subjected to the Evolvo @-@ Ray as part of Cortex 's plan to make Crash the " general " of his " Cortex Commandos " , which would be used to dominate the world . However , he is later deemed unworthy of being in Cortex 's army and escapes from Cortex 's castle . As an act of revenge and to rescue a female bandicoot named Tawna , Crash travels through the Wumpa Islands , defeating Cortex 's henchmen along the way . He eventually steals Cortex 's airship , defeats Doctor Cortex , and escapes alongside Tawna . A year later in Crash Bandicoot 2 : Cortex Strikes Back , Crash is sent off to get a new laptop battery for his sister Coco , but is soon abducted by Doctor Neo Cortex , who claims to have changed his ways . Crash is then ordered to gather Crystals for Cortex while fighting off opposition from Doctor Nitrus Brio . Once Cortex reveals his hidden intentions , Crash sends Cortex flying off into space and aids Nitrus Brio in destroying Cortex 's space station . In Crash Bandicoot 3 : Warped , when the remains of the space station crash into Earth and set the demonic Uka Uka free , Crash is recruited by Aku Aku to use Doctor Nefarious Tropy 's Time @-@ Twisting Machine to gather the powerful Crystals in their original places before Cortex does . Crash eventually gathers all 25 Crystals and defeats Nefarious Tropy , causing the Time @-@ Twisting Machine to implode on itself . In Crash Bandicoot : The Wrath of Cortex , Crash is recruited to gather Crystals and return a group of destructive masks named the Elementals to a hibernation state and stop Cortex 's new superweapon Crunch Bandicoot . In Crash Twinsanity , after foiling another plot by Doctor Cortex to eliminate him , Crash teams up with Cortex in order to defeat the Evil Twins and restore the natural order of the universe .
