Season 1

Skeletor has managed to find the legendary 'Diamond Ray Of Disappearance', a mystical jewel that sends who or whatever it is aimed at vanishing into another dimension. Calling his warriors from around the Universe, Skeletor plans to use the magical gem to get rid of He-Man once-and-for-all. His first victims are King Randor, Queen Marlena, and Man-At-Arms, as well as The Sorceress of Grayskull, and it is up to He-Man to destroy the jewel, freeing his friends from the distant limbo-like dimension that they are trapped in...

After Queen Marlena, using Man-At-Arm's new 'mind projector', relives how she came to crash-land on Eternia years before, Teela tries to use the device to learn who her mother is, but is frustrated when it is unable to display the image. She decides to head to the Crysal Sea, in search of the legendary Oracle, the only thing on Eternia that could possibly tell her of her true parents. But Mer-Man, defeated years before by Man-At-Arms, is looking to get even, and plans to use Teela as a sacrifice to a sea God...

Skeletor's latest invention, the Collector, is capable of bringing stone statues to life and turning people to stone. With Beast Man, he attacks the Royal Palace with the new device, bringing court-yard statues to life and freezing Man-At-Arms in stone. If the effect isn't reversed by sundown, he will be cast in stone forever. As He-Man, advised by The Sorceress, goes to search for the one thing that can aid them in reversing the spell, Skeletor uses the energy the Collector has taken from his victims to awaken an ancient, giant statue, and turns it on Castle Grayskull...

Skeletor and Beast Man steal a dragon's eggs and transport them into the court-yard of the Royal Palace. With their special growth enhancer, the dragons soon hatch and grow, attacking the Palace, and leaving the Heroic Warriors distracted trying to deal with the ever-growing dragons leaving Skeletor and his cronies free tackle Castle Grayskull...

Skeletor and Evil-Lyn break into the temple of the Fire People and steal the Spellstone, with which they unleash a terrible storm. While He-Man, with Ram Man, Stratos and Battle Cat, goes off to try and retrieve the Spellstone, Evil-Lyn magically disguises herself as an old lady, and convinces Eternia's peasants that the storm was a result of the Elders being angry at the Royal family. She soon convinces them to unleash the Creeping Horac - an ever-growing weed-like entity that covers buildings and gradually sucks away the air - onto the Royal Palace...

The Sorceress sends He-Man, Man-At-Arms, Orko and Battle Cat back in time after Skeletor, who, with Tri-Klops and Fang Man, has gone back into Eternia's past to plant an effective time bomb on the spot where Castle Grayskull now stands, that will destroy it in the present unless He-Man manages to stop it "in time"...

When King Randor's beautiful but snobbish and stuck-up niece Lady Edwina comes to stay at the Palace, Orko is attracted to her and tries unsuccessfully to impress her. He thinks back to a magical medallion that he once had when he arrived on Eternia years before in a freak storm, when he saved a young Prince Adam and Cringer from the Tar Swamp, losing the medallion in the process. He heads off to the swamps to try and find the lost charm to impress Edwina, but unfortunately he is there at exactly the same time as Skeletor, who, with Evil Lyn and Beast Man, has come up with a magical potion to resurrect ancient beasts from the swamp to use in an attack on the Royal Palace...

Adam, Teela, Orko, Cringer and Lizard Man are on a visit to Pangus, the King of the city of Tarinth, when the city comes under a fierce trembling. Adam is about to come to the rescue as He-Man when a young woman called Celice appears and soothes the tremors with her singing. Pangus explains that a terrible creature lives beneath the city, and only Celice's soothing singing can calm it. Skeletor oversees the whole scene and decides that Celice's singing powers would be of great use to him. Evil-Lyn kidnaps the girl with Trap Jaw, and possesses her; Skeletor plans to use her siren song to hypnotise The Sorceress and then to sing Castle Grayskull's jaw-bridge open...

For many years, the Royal Palace of Eternia has had shipments of photanium (the strongest metal in the Universe) from the moon of Phantos to make weapons with, but Skeletor intends to from now on step in and have the photanium all for himself. Man-At-Arms is given worthless ore instead of the photanium, and when the moon's ruler, Queen Elmora, puts up a fight against the plans, Skeletor casts a spell on her that ages her and turns her evil. Realising the metal they've been given is useless, He-Man and co. head to Phantos to see what's going on, only to find themselves on the moon where Skeletor now drives slaves mining for the metal...

Skeletor and his latest allies, the tribal-like Torgs, are trying to awaken Mulkram, a giant, diabolical monster who was frozen by the Elders centuries ago to stop his reign of terror. He-Man, Teela, Man-At-Arms, Orko and Ram Man are in the city of Avion for the annual ceremony where Stratos presents the magical Staff of Avion to his people, but just as the ceremony is about to begin, the Torgs attack, capturing Stratos and the staff. Skeletor intends to use the staff's amazing powers to awaken Mulkram, and to use the mighty creature to enter Castle Grayskull...

After He-Man puts an end to their latest plot, Skeletor and Beast Man plan to get rid of him once and for all; with use of invisible helmets they sneak into the Royal Palace and kidnap Prince Adam, to use as bait to lure He-Man out into a trap. Unfortunately, one of Orko's magic spells has gone wrong, teleporting the Sword Of Power away into Eternia's distant past, leaving Adam unable to transform into He-Man. While the Sorceress sends Orko and Cringer back in time to try and retrieve the sword, she has a special assignment for Man-At-Arms to trick Skeletor into believing that He-Man is about when he is not...

Skeletor wants to steal the Widgets' Coridite- a powerful mineral substance, out of which He-Man's harness is made. Evil-Lyn devises a cunning scheme to help him; she disguises herself as a young girl lost in the forest, and persuades the Widgets to let her enter their fortress. She then tricks the Widget guard Squinch into letting her enter the private chamber where the Coridite is kept, then she steals the Coridite and takes it to Skeletor! Skeletor plans to use the Coridite to form himself a new chest plate that will make him as powerful as He-Man- can He-Man stop Skeletor's scheme and retrieve the Coridite before his most dangerous foe becomes as powerful as him?

On hearing the threat to his world, where he is a great magician, Orko promptly returns with Dree Elle in the pyramid. Knowing that their friend will need some help, He-Man and Battle Cat get The Sorceress to open a portal to send them to Trolla to help their friend, and find themselves in Orko's bizarre, back-to-front world, where they must put an end to Dragoon's reign of terror before sundown, or the portal back to Eternia will close...

Beast Man spots the touring party, and aided by his Shadow People followers, he ambushes them. Determined to prove his worth to his father, Adam resists transforming into He-Man and instead tries to stop the attack as himself, but he is overpowered, and Beast Man captures Randor, intending to use his capture to win his way back into Skeletor's good books...

Meanwhile, an evil sorcerer called Jarvan, who was previously defeated by He-Man and Man-At-Arms, has escaped from the prison mines and has set his sights on the Transmutator. Preying on Ileena's depression, he disguises himself as a kindly old woman and gives Ileena a 'magic potion' that will boost her confidence and strength.

But their task proves far from easy- for not only is Granamyr suspicious of humans and reluctant to help them, but he says he will only give them the spell if they cut down the living tree named Skytree. Will He-Man willingly take a life if it is the only way to save that of his friend?
