Crash Bandicoot is the main titular protagonist of the Crash Bandicoot series. Originally planned to be named Willie the Wombat, he is an Eastern Barred Bandicoot living on N. Sanity Island, who was captured and evolved by Doctor Neo Cortex. Throughout the series, Cortex is Crash's usual arch-enemy and is alway defeated by Crash in order to keep peace around the island. Crash is often accompanied by his ally, Aku Aku, the series deuteragonist. In the earlier games, he tended to say "Whoa!" whenever he got killed. In the later games, he spoke gibberish with a very basic knowledge of the language spoken in the game.
