 Crash was genetically engineered through the use of Cortex and Doctor Nitrus Brio 's Evolvo @-@ Ray . Before escaping from Doctor Neo Cortex 's island fortress , Crash became romantically attached to a female bandicoot named Tawna , who was another one of Cortex 's experiments . Crash 's separation from Tawna at the hands of Cortex serves as the primary root of Crash 's <unk> of Cortex . Crash is a very emotional character who is quick to laugh and quick to cry . While he has a danger @-@ loving , fearless nature and loves a good fight , he prefers relaxing in the sun and rarely seeks out trouble deliberately . Crash has an extremely limited vocabulary , preferring to speak in unintelligible gibberish ; the few English words he is capable of speaking include " Whoa ! " ( which he often exclaims upon being physically harmed ) , " Nina " and " pancakes " . To the ire of his friend Crunch , but the amusement of his sister Coco , Crash is prone to impolite personal habits such as belching or scratching his posterior .
