CO2

CO2 was a castaway on Survivor: Fans vs Favourites.

'''CO2 was instantly hated around camp for his pessimistic and antisocial attitude, apart from a close bond with fellow outcast Gramophone. When CO2 reneged from the plan to vote out Gramophone and voted Mouse, the Lairo Tribe split their votes between Wasabi and CO2 rather than Wasabi and Mouse, leaving CO2 with enough votes to be voted out.'''
