Crash started his life as an ordinary bandicoot in the wild until he was taken from the jungle and genetically enhanced by an evil scientist named Dr. Neo Cortex, by using a machine called the Evolvo-Ray. He was 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. But, Cortex considered him a failure due to his kind nature, resulting in Cortex chasing Crash out of the castle. While Crash has a danger-loving, fearless nature, and loves a good fight, he prefers relaxing in the sun and rarely seeks out trouble deliberately. He has an extremely limited vocabulary because he speaks in unintelligible gibberish, but has a very basic knowledge of English. Crash has significant physical strength, and is also very agile. He lives on Wumpa Island in a medium-sized hut with Coco (his sister), Tawna (his girlfriend), and their very good friend, Crunch.
Crash's friends include:
Coco Bandicoot, Tawna Bandicoot, Crunch Bandicoot, and Aku Aku
Crash's enemies include:
Dr. Neo Cortex, Dr. Nitrus Brio (sometimes), Dr. N. Gin (sometimes), Tiny Tiger, Dr. N. Tropy, and Uka Uka
