Nash

Nash is a shark creature from the planet Barin. He is one of Emperor Velo XXVII's champions. You can unlock him in the GameBoy version by beating him the first time at Barin. He appears to have a laser cannon like device on his helmet.

Crash Nitro Kart
Nash was only seen in Crash Nitro Kart. He is apparently genetically engineered to never stop moving. Being Barin's champion, he races for his planet. When Team Bandicoot beats him, Coco hacks into his helmet and puts him to sleep. When Team Cortex beats him, N. Gin suggests to Cortex that they should use cybernetic sharks as henchmen.

Personality
Nash seems to be very bad tempered, high strung, and has a very bad attitude. He's cocky and never stops moving, until Coco puts him to sleep.
