Weather Controling Satellite
Duncan's remote control
The Weather Controling Satellite was one of Man-At-Arms's inventions seen in He-Man and the Masters of the Universe.
Man-At-Arms intended to use his Weather Controling Satellite to make the rulers of Eternia "masters of the seasons" as he told King Randor. With one push of a button on his remote control, Duncan could use the Satellite to turn a cloudy sky to clear. Man-At-Arms proceeded to do just that when he first presented his invention to the King. However, a great storm appeared in the sky almost immediately following Duncan's presentation. Man-At-Arms was certain that his device could not have been able to create such such a storm, and confided in Prince Adam that the only thing capable of doing such a thing was the legendary Spellstone, and then only if it had fallen into the hands of someone evil.
Later, an elderly woman named Zenia (actually a disguised Evil-Lyn) accused Randor and Man-At-Arms for the bad weather that was ravaging the region by experimenting with the Weather Controling Satellite. Zenia told the villagers that Man-At-Arm's inventions had angered the Elders of Eternia and caused the storm and said the Royal Family had to be punished.
