John Silver

John Silver is the deuteragonist of Disney's 2002 animated feature film, Treasure Planet.

Personality
Silver is rather greedy and cunning, having spent most of his life searching for the treasure of Captain Flint, but he has a caring side, too, and understands that friendship can be more important than treasure. He dislikes unnecessary acts of violence and cruelty, originally intending to mutiny only after the treasure was in hand, and thus, avoiding bloodshed as much as possible, and is generally honest and honorable in his piratical dealings. Nonetheless, he maintains a constant air of harsh brutality and deception around his crewmates, understandably necessary to maintain his position as their leader.

Physical appearance
Based on Long John Silver from the original novel, he is a cyborg: part machine, part organic. His alien form resembles a cross between some sort of bear and human (and robot), identified as the alien species Ursid, though they never mention this in the movie itself. He has a cyborg arm, leg, ear, and eye from some unknown incident, though he mentions when asked by Jim that "You give up a few things, chasing a dream.", so presumably they were lost in his search for Treasure Planet. His cyborg arm serves many purposes, such as cooking implements, a sword, a pistol and welding tool, and his cyborg eye has zoom functions and improves his aim, while his mechanical leg appears to contain an addition that he can put on his arm's mechanics to create a low-grade plasma cannon.
