Master Control Robot is a piece of technology that appears in the animated series The New Adventures of He-Man.
The Master Control Robot provided both the energy source and the designs for everything the people of the planet Makkina needed. Merely by indicating their needs, they could change the automatic production line to whatever they chose.
When representatives of the Evil Mutants and the Galactic Guardians both visited Makkina and learned about the Master Control Robot, Skeletor wanted to get his hands on this highly advanced piece of technology for himself. As soon as the robot Protectons realized that the Mutants and Primans were at war with each other, they decided to put an end to this conflict by occupying both Primus and Denebria. Both visiting parties were immediately captured in Energy Nets. But He-Man called upon the way of the magic to guide his power sword as he trew it at the Energy Net control system, destroying it and freeing his friends as well as his enemies.
The Guardians were on the run from the Protectons when Emar appeared and told them to follow him. He revealed himself to be part of a resistance against the machines. The Mutants follow them into the resistance underground tunnels, thinking they will lead to the Master Control Robot. Three dangerous bariers had to be passed in order to reach the Master Control Robot, but He-Man managed to get through the first two with ease and with a little help from Gleep, also passed the third.
It turned out the Master Control Robot had duplicated himself. Each one of it's smaller versions could control all of the machines on Makkina. He-Man was captured in a static cage by the Protectons. The Mutants grabbed one of the duplicate brains and summoned their Mothership, which blasted a hole in the ceiling and used a tractor beam to retrieve the Mutants. He-Man managed to break free from his electronic prison and asked Emar and Zak to reprogram the Master Control Robot.
Meanwhile, Skeletor had one of his Tech Mutants install the computer brain on the Mothership. But instead of giving it ultimate power, it drained all the power of the ship, leaving it floating helplessly in space. He-Man and the Guardians kept fighting the Protectons until Emar and Zak managed to disconnect the Master Control, causing all the robots to lose their power. Zak wanted to destroy them all, but Emar vowed to rebuild and reprogram them so that this time, the Makkinaks would remain in charge.
