Long John Silver, also referred to as the Cyborg by Billy Bones or also simply known as John Silver, is the former main antagonist-turned-deuteragonist of Disney's 43rd full-length animated feature film Treasure Planet, which is loosely based on the 1883 Scottish adventure book Treasure Island by the late Robert Louis Stevenson. He was based on the character of the same name from the book.
He is a cybernetic bear-like alien pirate captain who spends most of his life finding Treasure Planet and achieving wealth. Silver is two-sided. On one side, he was greedy and ruthless, seeking to dispose of anyone who gets in his way in getting the treasure. On the other, he has a soft side to Jim Hawkins and forms an unanticipated father-son like bond with him. It was thanks to Jim that Silver begins to slowly redeem himself.
He was voiced by the late Brian Murray.
He is the second Disney Villain in the Disney Animated Canon to be redeemed after Amos Slade from The Fox and the Hound
