Game:Master Control Program

The Master Control Program is an enemy in Kingdom Hearts II, located in Space Paranoids. He must be fought alongside Commander Sark.

Kingdom Hearts II
Attack the walls surrounding him and use the Reaction Command. This is the only way to defeat him. You must have Tron in your party.

Since reaction commands technically count as hits this is a great way to level up Valor Form.

Sark does all the attacking. During the battle with the MCP, Sark again throws his disk (which has proportionately increased in size) and shocks the ground when Sora is close. He also raises a wall, which allows Sora to again use the Reaction command, instantly destroying the head. Sark's two feet must be damaged to make him kneel, so his head can be attacked - destroying the head stuns Sark for some time, but he will be regenerated by the MCP.

Valor Training Tip
Since Delete counts as multiple hits in Valor Form, This is a great battle to train Valor. Hitting the Defensive Walls also count. Hit Sark if your drive runs low. Have the Oblivion Keyblade and Drive Boost Abillity equipped. For added covenience, fight the MCP after obtaining Final form.

MCP
"Eliminate all threats!" "I will repair your data." "Is that the best a User can do?" "Insignificant User!"

Sark
"Going somewhere?!" "Data error detected!"
