[1] The main premise revolves around the conflict between He-Man (the alter ego of Prince Adam) and Skeletor on the planet Eternia, with a vast lineup of supporting characters in a hybrid setting of medieval sword and sorcery, and sci-fi technology.

[6][7][8] Set in a hybrid world of sword and sorcery and technological sci-fi, He-Man battles with Skeletor to prevent him from conquering Eternia and discovering the secrets of Castle Grayskull—a mysterious ancient fortress with a skull-shaped facade, containing great power and magic.

[15] He-Man's most prominent allies include Man-At-Arms,[16] a wise loyal veteran soldier and inventor; and his adopted daughter Teela, a spirited and skillful female warrior, often portrayed as captain of the Eternian Royal Guard and a potential love interest of He-Man/Prince Adam.

[17] The childlike Trollan magician Orko also often features as one of He-Man's closest allies;[18] as does Stratos, a flying bird-man from the kingdom of Avion;[19] Ram-Man, a stout dimwitted warrior with springlike legs and a large helmet that encloses his head and upper torso;[20] and Man-E-Faces, an actor with face-changing abilities.

[31] Other main characters of the She-Ra series would include Swift Wind, winged unicorn and alter ego of She-Ra's trusty steed Spirit;[32] Light Hope, mystical living beam of light and mentor to She-Ra;[33] and her Great Rebellion allies Glimmer, magically inclined onetime leader of the rebellion;[34] Bow, skilled archer and the main male protagonist of the series;[35] Kowl, Bow's owllike, rainbow-eared companion;[36] Madame Razz, absent-minded witch with her sarcastic sentient Broom;[37][38] and Queen Angella, Glimmer's mother and angel-winged queen of the Bright Moon;[39] along with Hordak's spell-casting witch Shadow Weaver;[40] shape-shifting spy Imp;[41] bumbling bug-eyed henchman Mantenna;[42] Force Squad captain Catra;[43] evil scientist Modulok;[44] beastly warrior Grizzlor;[45] energy-draining Leech;[46] and thuggish henchwoman Scorpia.

[49][50][51] However, popularity had waned by the end of 1987 and a planned continuation of the original toy line under the heading of "The Powers of Grayskull" (set in ancient Eternia, featuring the villain King Hiss and He-Man's ancestor He-Ro) was started, but eventually scrapped.

[55][56] As part of the relaunch, a modern updated animated series was also created by Mike Young Productions, lasting for 39 episodes; featuring He-Man and his ensemble of heroic warriors, now called the "Masters of the Universe," battling Skeletor's minions and, later, King Hiss, the ancient and evil lord of the Snake Men.

[98] The original four mini comics, He-Man and the Power Sword, The King of Castle Grayskull, Battle in the Clouds, and The Vengeance of Skeletor were made by Mattel in 1981 and written by Donald F. Glut, with artwork by Alfredo Alcala.

[13] Other entries into the Masters of the Universe mythos, such as Cringer as the alter ego of Battle Cat, Zodac as a neutral cosmic enforcer, Stratos as leader of his home world of Avion, and Adam's mother, Queen Marlena, as an astronaut hailing from Earth, were all partly introduced in these early DC issues.

[18] Rounding out the main cast of heroes is Teela (now firmly depicted with red hair, she is the Captain of the Royal Guard, the adopted daughter of Man-At-Arms, and secret child of the Sorceress; who serves as a teasing and semi-antagonistic love interest of Adam and He-Man throughout the series).

[128] Often this group of evil minions consists of the cunning female sorcerer Evil-Lyn (making her full debut into the MOTU mythos as Skeletor's most dangerous counterpart in the Filmation series)[26] and his most frequent sidekicks: the bumbling Beast Man (who possesses the ability to control various creatures through telepathy) and the equally inept weapon-armed Trap Jaw.

[172] The Great Rebellion is originally led by Queen Angela (winged queen of Bright Moon, freed by She-Ra from the clutches of Hunga the Harpy)[39] and her daughter Glimmer (pink-haired magic user with the ability to manipulate light),[34] with the main cast of the Princess of Power cartoon also including the skilled archer Bow (the main male heroic character of the series),[35] Bow's timid companion Kowl (a flying owl-/koala-like creature with large rainbow-colored ears),[36] and the absent-minded magician Madame Razz and her wise-cracking sidekick, Broom.

[37][38] Also appearing in many episodes are the small imp-like forest-dwelling Twiggits (mainly Sprockett, Spritina, and Spragg)[173] and the mystical Light Hope, who serves as a "Sorceress of Grayskull–type" guide to She-Ra, residing high atop Mount Skydancer in the Crystal Castle.

[175] The Force Squad, lead originally by Adora and now by Catra (raven-haired villainess with a magic mask, giving her the ability to turn into a vicious panther),[43] consists of the bug-eyed Mantenna (whom Hordak loves to torment, often dropping him through trapdoors),[42] the fearsome Beast Island operator Grizzlor,[45] the hulking life-force-draining amphibian-like Leech,[46] the whiny shape-shifting Imp,[41] and the pincer-clawed scorpion woman Scorpia.

[179] Some of the other popular one-off heroes and villains were Spinnerella, Huntara, General Sunder, False-Face, Colonel Blast, the Red Knight, Granita the comet warrior, Sorrowful the Dragon, the Meteorbs, and the Star Sisters.

Alan Oppenheimer and John Erwin would reprise their roles from the He-Man and the Masters of the Universe series, as would Linda Gary with Teela and the Sorceress, while providing additional voice work for Glimmer, Madame Razz, Sweet Bee, Shadow Weaver, Scorpia, and Entrapta.

[184] Also that same year, "the land and sky disc launcher", Blaster Hawk, and "the road rocket", Laser Bolt, were produced for He-Man's heroic warriors; while Skeletor gained the "dragonfly attack vehicle", known as the Fright Fighter.

[52][189] Another major mini comic storyline of this period included the introduction of the three-towered fortress of Eternia in The Ultimate Battleground, which was a massive final playset for MOTU, one of the biggest of all 1980s toy lines, complete with a motorized monorail circling the towers.

Other notable mini comics included the debut of Hordak's gruesome mind-altering Slime Pit in Escape from the Slime Pit, one of several origin stories for Rokkon and Stonedar in Rock People to the Rescue, cybernetic Horde experiments resulting in the creation of the warriors Dragstor and Extendar in The Warrior Machine, and the suggested origin of Skeletor as Keldor in The Search for Keldor (which also included the only mini comic appearances for He-Man's ally Clamp Champ, and Skeletor's minions Ninjor, Scare Glow, and Faker).

These series five and six mini comics were often edited by Lee Nordling with art direction from Ron Cook, and included writing by Tim Kiplin, Phil White, and Steven Grant, with the artwork of Bruce Timm, Jim Mitchell, Chris Carlson, Charles Simpson, and Larry Houston, among others.

Directed by Tony Christopher, husband-and-wife team Jack and Leslie Wadsworth portrayed He-Man and She-Ra, while Khalos Planchart and Eric Van Baars played lead villains Hordak and Skeletor, respectively.

Skeletor's henchmen Blade (Anthony De Longis), Saurod (Pons Maar), and Karg (Robert Towers) were also introduced, in place of other more familiar villains from the established continuity, such as Tri-Klops, Mer-Man, and Trap Jaw.

Stranded on Earth, they are faced with the task of retrieving their Cosmic Key (which has fallen into the hands of the unwitting humans Julie Winston and Kevin Corrigan) and returning to Eternia, before Skeletor can gain the full power of Castle Grayskull.

Under the leadership of Man-At-Arms (voiced by Garry Chalk), this team originally consisted of He-Man/Adam (with his pet Cringer/Battle Cat, no longer able to speak), Teela, Orko, Stratos, Ram-Man, Mekaneck, and Man-E-Faces, and later joined by Buzz-Off, Roboto, and Sy-Klone.

In these issues, He-Man goes back in time to battle King Hiss, finally bringing He-Ro, Eldor, Tytus, and Megator into the storylines and introducing newly created Classics characters such as Sir Laser-Lot and the Mighty Spector.

The Fall of Eternia saga in the final issues incorporates the proposed Dare, son of He-Man (He-Ro II) series from the 1990s, along with Gorpo (the Unnamed One) and many "Create-a-character" contest finalist designs from the 1980s Masters of the Universe Magazine.

Many of these stories are meant to be read in conjunction with the altered continuity presented in the character biographies on the cardbacks of the Masters of the Universes Classic's line action figure packaging, and thus do not provide a detailed flowing narrative in the mini comics themselves.

Also appearing in the series are Swift Wind (without the alter ego of Spirit and with a completely different take on the character's personality), Light Hope (as a female hologram generated by the "First Ones"), Sea Hawk (now presented as a more comical glory-seeking associate of Mermista), Castaspella (as the sister of Angella's husband King Micah), Madame Razz (as an older and confused forest dweller with knowledge of Mara, a prior "She-Ra"), Netossa and Spinnerella.

Shadow Weaver (Lorraine Toussaint) and Scorpia (Lauren Ash) also play prominent roles within the series, and cadets Lonnie, Rogelio and Kyle are introduced (possibly inspired by previous Filmation characters).

[298] On January 22, 2016, Deadline reported that McG would direct the film and also oversee a rewrite of the latest script by Alex Litvak and Mike Finch, while Escape Artists' Todd Black, Jason Blumenthal and Steve Tisch and as well as DeVon Franklin were now on board as producers.
