Coco Bandicoot is the tritagonist in the Crash Bandicootseries and is the highly intelligent, cute, and spirited younger sister of Crash Bandicoot. She often aids her big brother by using her computer hacking techniques to assist him, building gadgets ideal for the situation or even tagging along with him in his journeys, using self-taught martial arts to defend herself. She first appeared in Crash Bandicoot 2: Cortex Strikes Back, and her first appearance as a playable character was in Crash Bandicoot 3: Warped. Since then, she has appeared in every Crash game.
Just as her brother was, Coco was an ordinary Bandicoot until she was taken from the jungle and genetically enhanced by Doctor Nitrus Brio and Neo Cortex. It is unknown how she came to live with Crash afterward as she was not seen in the first game stating how Crash and Tawna were created.
And she is reprised by Debi Derrberry in the English dub and Satomi Arai in the Japanese dub.
