Commander Sark is the MCP's second-in-command. He is a villain in Disney's Tron (1982).

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.

The movie
Sark is played by David Warner in the film Tron. In Tron, Sark is commanded by the MCP to train to the point of death a man digitalized into the computor named Kevin Flynn. Sark and his elite force of programs dominated over the game grid, but for one exception: A program named Tron. Tron had been a thorn in his back for a while, and he despised him. When Kevin shows up, him and Tron escape, angering Sark. Fearing punishment from the MCP for his mistake, Sark sends battle programs after the escaping programs. The two escape, and plan to derezz (Destroy) the MCP and Sark, to bring peace to the computor system. They make to the MCP's stronghold, but must face an angered Sark. Sark is skilled in data-disk combat, and is difficult for Tron defeat. He ventually defeats him. Sark reveals that he and Tron could have made a great team. MCP, desperate, gives all his power-programs to Sark, This results in Sark growing to enourmous size. The gigantic Sark lumbers over to Tron and Kevin. Thinking quickly, Tron leapg into the void of the MCP, derezzing him and Sark for good.
