Kingdom Hearts II
Guardian Soul is very useful here because its ability, Reaction Boost, makes the battle easier. During the battle with the MCP, Sark again throws his disk (which has proportionately increased in size) and can shock the ground when Sora is close. He sometimes raises a wall if Sora tries to run from him, which allows Sora to use the "Needle Dive" Reaction Command, instantly destroying the head. The other way to get rid of Sark is to attack Sark's legs to make him kneel, this allows his head to be attacked—destroying the head stuns Sark for some time, but he will be regenerated by the MCP.

The MCP is surrounded by walls protecting his core, Sora needs to attack the walls and use the "Delete" Reaction Command in order to defeat him. Tron cannot be knocked out or Sora will be unable to use "Delete".

After decreasing the MCP's HP with "Delete", he will surround the walls with electricity and cause them to spin rapidly. Any broken walls will regenerate and the "Delete" attack will end. The MCP can also fire lasers from the walls, which might be a problem when trying to attack the walls. Heal when necessary.

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 the Drive gauge runs low. Be sure to equip Sora with the Drive Boost Ability.
