When the energy in the Sunstone runs out, the Keepers of the Temple of The Sun decide it is time for the recharging ceremony, which can only happen once every one hundred years when the sun is in the perfect position. The ceremony calls for the presence of the strongest forces for good in the universe, so the keepers invite He-Man and Battle Cat.
They bring Man-At-Arms, Teela, and Orko with them in the Attak Trak, which is suddenly stopped in the sands by the presence of a giant bottle. Orko uncorks it to reveal Prankster, a Trollan who plays gags and tricks and will only return to his dimension when his true name is spoken. His gags are made dangerous when Negator uses his power to corrupt Prankster's magic. When He-Man arrives at the Temple of The Sun, the ceremony begins.
Negator steals the Sunstone and uses its power to grow larger. Prankster unleashes a rainstorm and Negator is absorbed by the Sunstone, but not before he creates an electrical storm. He-Man uses his sword to redirect the electrical energy into the Sunstone. At the Palace, Adam tricks Prankster into revealing his name is Wokrapanwookie, sending him back to Trolla.
