Coco Bandicoot is a major character in the Crash Bandicoot series and is the highly intelligent and spirited younger sister of Crash Bandicoot. She often aids her big brother by 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. Her first appearance as a playable character was in Crash Bandicoot 3: Warped.
Just as her brother was, Coco was an ordinary bandicoot until she was taken from the jungle and genetically enhanced by Doctor Nitrus Brio to help Crash defeats Neo Cortex. It is unknown how she came to live with Crash afterwards as she was not seen in the first game stating how Crash and Tawna were created..
