The End of the World
Skeleter has succeeded in gaining control of the mystic planet Antiworld. He plans to crash it into Eternia so that everything is wiped out; can the Heroic Warriors stop him? Prince Adam receives a message from the Sorceress and travels to Grayskull as He-Man. There, she shows him a vision of the coming disaster. Shocked, he gathers Battle Cat and Man-At-Arms, and they travel to to the planet in the Wind Raider. Meanwhile, back on Eternia, Mer-Man, Beast Man, and Zodac meet in secret and confront Skeletor about the fact that they'll be destroyed as well, if the worlds collide. But it's too late: Trap Jaw accidentally falls on the magic mirror that serves as the link to Antiworld and destroys it, so not even Skeletor can stop the coming disaster. Suddenly, as He-Man grapples with the planet, itinto a paradise! Just then, a group of ancient spirits arrive. Long ago, they banned the evil of their world to another planet: Antiworld. However, they lost sight and control of it, and Skeletor took it over. The ghosts say they will use their powers to repair the damage done to Eternia, and transform into doves and fly away...

The Day of the Cursed Skulls
Deep in the depths of Snake Moutain, Skeletor is using his black magic to break the curse on the banned souls of the evil dead. It works, and the skeletons aborb the evil powers and are reanimated. Skeletor issues a command to destroy Eternos, but on their march Stratos sees the army and warns He-Man. Together, they go to the army and attempt to destroy it, but as soon as he shatters one skeleton, it comes back together! Tri-Klops arrives and feeds the cursed skeletons with hellfire, who, in turn, fire all the negative energy at He-Man, causing his strength to drain. Retreating, he decides he must find the source of their power, which turns out to be Hell itself! Arriving at Grayskull, he yells, "By the power of Grayskull! Close the Gate of Hell and destroy this curse for all time!" It works, and the threat ends.
