Crash Bandicoot is an Eastern Barred Bandicoot living life 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 always defeated by Crash in order to keep peace around the island. Crash is often accompanied by his ally, Aku Aku, the secondary protagonist. 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.
