His alien appearance resembles that of a green dinosaur with the exception of his pick-axe-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. During the voyage, the ship encounters a supernova. Jim (while securing lifelines of all pirates) saves Silver from falling just in time. The supernova then devolves into a black hole, where Arrow falls. The burst of shock waves and maximum engine power enable Amelia to pilot the ship to safety. Amelia mourns the loss of Arrow, and suspects Jim of failing to secure the lifelines, while Arrow's line was actually cut by Scroop. He is also 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.
- His death is similar to Charles Muntz, who is also voiced by Christopher Plummer.
