2x61 - He-Man and the Masters of the Universe

Remembering the failure of his last attempt to control The Cosmic Comet, Skeletor decides he can only control the comets if he controls Zagraz, the comet keeper. He sends Two Bad out to capture Zagraz, and with the comet keeper in his clutches, Skeletor sets out using the comets to attack the Royal Palace and Castle Grayskull.
