Master Control Program



The Master Control Program, or MCP was the highest-ranking program in the Hollow Bastion OS.

Ansem's computer
The MCP was copied from ENCOM's original system and modified for Ansem the Wise's use. However, the MCP portion was unactivated until Xehanort modified the program and hid data on the Heartless and Nobodies. By then, the MCP started his rule over the rest of the computer network, with Sark as his henchman. Tron confronted the MCP in a battle where he lost many of his functions to the MCP. However, Tron's life was spared as the MCP needed the password contained in Tron's data for the DTD(Door To Darkness).

Later, angered by Donald's misuse of a terminal, the MCP digitized Sora and his friends into Space Paranoids, where they were kept prisoner in a cell with Tron. After Sora left Space Paranoids and returned with the password to the DTD, the MCP quickly took over the DTD, triggering a emergency destruct program for the Radiant Garden town. Tron was able to create a new password to lock out the MCP from the DTD, and the destruct program was defeated.

After Sora journeyed off to the worlds again, the MCP took control of the defensive system for the town, using it to attack the residents and Sora, while downloading digital Heartless into the Users' world. Sora entered Space Paranoids again, and helped Tron obtain Cid's MCP Eradication program. They set off for the MCP's mesa, and defeated Sark. Sark was resurrected, with the MCP giving his functions to Sark. This was in vain, as Sora and Tron were able to knock out Sark enough for Tron to use his program on the MCP, deleting it from memory.After defeating the MCP, Tron becomes the new lead program in the computer. He helps the people of Hollow Bastion remember the world's original name, Radiant Garden where Kairi was born.

Trivia
It can be argued that the MCP is the most powerful Disney Villain in the Kingdom Hearts games, due to the fact that he is the only one who can actually create Heartless rather than having to summon them, and because he is in Ansem's computer it is very likely that he has considerable knowledge of the Heartless, Nobodies, Xehanort and virtually every aspect of the mysteries that surround Ansem and his discoveries.
