The movie begins with a glimpse into the daily life of a teenage boy on the planet Eternia.

Prince Adam, son of King Randor and Queen Marlena is at the table with his Mother and sister in a home-school meets midieval times (not the family dinner theater chain) setup. Sitting near the table is Cringer, He-Man’s giant cat and favorite companion.

Queen Marlena announces that they are done learning for the day and may be excused.

Prince Adam and Cringer leave the castle and begin a journey across the vast courtyards of Castle Grayskull (their home) to meet with the Sorceress. He had long been more interested in the magical teachings she made available and was always eager to learn a few new tricks. Orko, a long-time friend from the extradimensional world of Trolla who had found himself stranded on Eternia during a cosmic storm, is already there trying out and totally botching another spell he had come up with.

While chatting with the Sorceress, Man-at-arms bursts through the door and announces that the castle is under attack. Prince Adam is shocked at the news. In his life he had been in many skirmishes with people outside the castle, but never had anyone dared to attack Grayskull. He dashes to the armory and grabs a sword and shield and heads to the castle walls. A large army is seen just outside the gates. At the front of the group, we see a floating barge-like carriage with a throne atop. And in that throne, a hideous creature made of muscle and bones, wearing a armor and carrying a huge staff with a skull of some sort attached to the top.

Prince Adam watched as the royal army opened the front gates of Grayskull and marched out to meet this mystery skeleton man and his army. The royal army was known for its superior skill and had a history of laying waste to any foe who dare cross King Randor and Queen Marlena, so there was no need to worry about the outcome. Prince Adam actually found it amusing that this skeleton man would even get close to the castle and was already picturing the 100 different ways he would be killed when he saw the unthinkable. A light shot from the staff of the mystery character and dozens of the royal army were blown back through the castle gates, several of them killed instantly and the rest horribly wounded.

Prince Adam turned to rush down to the gate but only got a few steps before he saw the Sorceress standing a few feet away. In a tone and seriousness that Prince Adam had never heard before, she shouted a few words of a spell and they were transported to her chambers along with Cringer, who of course had not left his side.

“Quick – we have no time to discuss this. There is a great secret that your parents and I have kept from you your entire life. I have prepared for this day since before your birth and must act quickly.” She raised her arms high and began to chant. Moving her arms around in a ver specific pattern, uttering words Prince Adam had never heard before. She moved faster and faster, got louder and louder for the next minute or two and then BAM! A huge sword appeared before her, floating in the air. She looked at Prince Adam and said “take it and….” POOF – she was gone. Just as she vanished, he was reaching out to grasp the sword and with her disappearance it fell toward the ground, but not before he could catch it’s weight and hold it in front of him.

There was silence. The Sorceress was gone, but where? He stood there for a minute and then turned to head back to the main gates. As he reached for the door, Orko appeared. “The Sorceress has been taken…..” Orko didn’t finish what he was going to say. He looked down at the sword that Adam was carrying and said “Thank the Gods! She got it to you in time. Come with me.”

Orko, Adam and Cringer returned to the castle walls to see the skeleton man and his army ride off into the distance, with the Sorceress held captive aboard his floating barge. Prince Adam moved as if to leap down to the lower level and Orko stopped him. “You can’t Prince Adam! She’s gone. You can’t go after her like this.” It took all his might to hold Prince Adam back. “You aren’t powerful enough!”

Orko then guided Adam and Cringer to the main throne room. King Randor and Queen Marlena both reacted to Prince Adams presence in the same way Orko did – with a Thank the Gods! response. Then, they began to tell Prince Adam of a plan many years in the making. The sword held magical abilities and could only be activated by the chosen one – in this case Adam. To access these powers, he need only raise the sword and utter a few words.

[INSERT Amazing transformation sequence here!] “By the Power of Grayskill – I have the Powerrrrrrrr”

Prince Adam transformed into He-Man for the first time and, at his side, Cringer became a fierce Battle Cat, complete with saddle and armor. Then, the montage of Mom, Dad and Orko explaining the plan, complete with custom song (not recorded by Sting) and He-Man testing his new sword and power on inanimate objects of all sizes. He DID have the power now.

Fast forward to He-Man approaching Snake Mountain on Battle Cat, with Orko, Man at Arms, Teela & a variety of action-figures-turned-live-action-heroes at their side. They storm the castle, enter Skeletor’s throne room (yeah – we learned his name from some villagers by this point) and an epic battle ensues. He-Man eventually overcomes Skeletor (but doesn’t kill him). They free the Sorceress and return to Grayskull.

There’s a giant feast and then all seems right in the land, but of course there is the impending threat of Skeletor, should he (well, when he) raises another army and tries to attack again.

At the end of the film, we see Skeletor limping from the throne room, out a secret door behind the throne and down a long corridor. He eventually enters another, very different looking door, and pulls himself into chamber that quickly fills with smoke and lights. As the chamber closes, the camera pulls back to reveal that he is actually inside of a space ship. And on the outside of that ship, some familiar logos.

Big reveal: We see King Randor and Queen Marlena back in their room at Castle Grayskull. Queen Marlena pulls a photo from a chest at the foot of her bed and she holds it up to King Randor as she speaks. “Did you see it? – His staff! It looked just like his tattoo.”

King Randor responded “Yeah – only Keldor could have known about that skull with the horns here. Nothing like that exists on this planet. It couldn’t be a coincidence.”

On this planet?

Keldor?

Tattoo?

We then see the photo up close and quickly piece it together. The royal couple are actually Randy and Marlene, members of a lost Mars expedition led by Elon Musk’s SpaceX. Their ship had veered off course and was thought lost, but it turns out the ship was pulled into a Black Hole just outside the Milky Way and thrust across the Universe, where it crash-landed on a planet they eventually named Eternia. They thought the rest of the crew had died as well, but in the photo we see another man, with a tattoo. The name on his uniform reads “Keldor.”
