Fayvoon is an antagonnist in Treasure Planet and one of the pirates in John Silver's crew. His alien appearance resembles that of a green dinosaur with the exception of his pick-ax-shaped head and his chameleon-like eyes that protrude from their sockets.
He took part in the attack on the Benbow Inn, evidenced by his shadow revealed from the inn's lamps. He is one of the first three pirates (the other two being Longbourne and Hands) to die in the film, when a misfire from Doppler resulted in falling debris, destroying the floorboards, and sending the pursuing pirates falling out of the ship's longboat room from a great height to their apparent deaths.
