The ruler of Eternia's sister planet, Infinita, Skeletor is always
trying to gain control of Castle Grayskull via a portal which allows him to go from
Infinita to Eternia. Fortunately for the people of
Eternia, He-Man and his friends are always there to stop this evil menace, no
matter what his plans may be. Skeletor carries a ram-headed staff with him, and
sometimes rides on his own cat, a purple version of Battle Cat named Panthor.
Beastman is a member of Skeletor's army. Though incredibly strong,
Beastman isn't very bright and almost never succeeds in capturing He-Man and his
friends.
Another member of Skeletor's army, Trap-Jaw has the ability to change
his many weapons by detaching and reattaching them from his arm. His other
weapons he carries on his belt until they are needed. Though he has these
weapons, he still almost never succeeds in capturing He-Man.
My favorite character of Skeletor's army, Tri-Klops--as his name
suggests--has three eyes. He is an above average fighter and sometimes carries a
sword.
Yet another member of Skeletor's army, Evil-Lyn is also a witch. She
performs magic spells to try and stop He-Man, but hardly ever succeeds. But I
will give her this; she sometimes gets farther than most of Skeletor's army in
her efforts to destroy He-Man.
Though spending most of his time at his home in the swamps of Infinita,
Merman is always ready to serve Skeletor. Another member of the army, Merman
isn't very bright (do we see a pattern here?). He sometimes carries a sword.
