Sark

Sark is a villain in Kingdom Hearts II. He is the MCP's second-in-command. His first appearance is a villain in Disney's Tron (1982). Originally portrayed by David Warner, as was the MCP, he and his master are voiced by Corey Burton, who does a convincing rendition of Warner's distinct British voice.

Journal Entry
''A powerful program who doesn't serve any user - just the MCP. Commander Sark is pretty harsh to any program that tries to resist his master's power.''

Description
Sark is a red battle program, designed to look like his creator Ed Dillinger, who also created the MCP. His voice is the same as his as well. Sark is the head of the game grid of the MCP. He trains programs to fight, and pits them up against other programs. He will do (or is forced to do) anything the MCP commands him to do. His primary weapon is a Data-Disc.

Story
Sark and the MCP are the main antagonists of Space Paranoids. Sark has been made a Heartless commander by the MCP, empowering him even more. Not much of Sark is heard of after his first appearance. His second appearance is at the boss battle against the MCP. First you fight normal Sark and his data-disk. Afterwards, he is a second-hand enemy as his giant-self while you fight the MCP. Like the movie, Sark is defeated along with the MCP.

Trivia

 * Corey Burton first voiced Sark while doing an ADR loop in place of David Warner. He would also reprise the voiceover in the Tron video games. Burton loved the sound of Warner's voice so much that he would carry the voice over into the Transformers cartoons as Decepticon Shockwave; a ruthless servant only loyal to his powerful master Megatron, much like the relationship between Sark and the MCP.
