Timeline: 66741-70000




  • May. The Trollan Orko emerges from a mystical maelstrom on the planet Eternia. Weakened by the loss of his focusing wand, he makes his way to Eternos and joins the court of King Randor.


  • November 13. Adora, youthful Horde soldier extraordinaire, finds himself drawn out into the lands of the rebel princesses through summons by way of the mysterious Lighthope. Asking her close friend Catra to cover for her, she runs into a pair of teens from the land of Bright Moon, who are immediately cast as her enemies. Bow, the young archer, and Glimmer, a fairy, capture her. When they are attacked by a giant spider monster, Adora takes a mysterious sword and transforms into She-Ra, a goddess of power. After she turns back, Glimmer keeps her from being able to transform again, and they are forced to flee the spider. They end up in a First Ones' stronghold, which begins to collapse, and Glimmer teleports them away.1
  • November 14. Coming across a village, Glimmer and Bow introduce Adora to a festival, and Adora begins to see that she has been working for the bad guys. This is reinforced when a Horde invasion force arrives, slaughtering the civilians and destroying the village. Catra appears, and Adora tries to show her the error of their ways, but Catra rejects Adora's pleas. Adora transforms into She-Ra after Glimmer accedes, and forces the Horde soldiers to retreat. Glimmer and Bow decide to bring Adora to Bright Moon along with a random horse.2
  • November 14. While waiting to be introduced to Glimmer's mother, Adora accidentally transforms the random horse into a winged unicorn. The locals discover her presence and she flees into the woods, where she meets the strange hermit woman Madam Razz. Razz helps her get an understanding of her role as She-Ra, including the ability to activate the power at will, and connects her with the winged steed, who has chosen the name Swift Wind. Adora meets Queen Angella, and introduces herself as She-Ra and swears her allegiance to the Rebellion.3
  • Adora, Glimmer, and Bow set out to reform the Rebellion's alliance.
  • December. Grune and Panthro (39) come across the tomb of Mumm-Ra, after Mumm-Ra telepathically influences the angry and frustrated Grune. Grune frees Mumm-Ra and betrays Panthro, throwing Panthro in a pit that he barely survives.4


August 29. While researching technology, Thunderan prince Lion-O (16) meets cleric Cheetara (19), who helps him fend off angry criminals. After a ceremony presenting the Sword of Omens to Lion-O, King Claudus's old friend General Grune appears with a lizard slave-led wheeled obelisk. Lion-O has some rivalry with his adoptive brother Tygra (19), and later, after defending a pair of Lizard men held in the stocks, he convinces his father to have them released.[9]
August 30. A Lizard invasion force moves against Thundera. Their advanced technology, coupled with the betrayal of Grune (whose obelisk carries the Lizard general Slithe and a horde of soldiers), results in the swift conquest and near annihilation of the Thunderan people. King Claudus dies after Mumm-Ra disguises himself as Claudus's old friend Panthro, and stabs him in the back. Lion-O, Tygra, Cheetara, and High Priest Jaga (70) are all taken captive. Lynx-O, Pumyra, and Bengali are amongst those who escape otherwise.[10]
August 31. Lion-O and Tygra escape their confinement due to the help of the Lizard Lion-O had pardoned prior. They confront Mumm-Ra and seize the Sword of Omens, escaping alongside Cheetara. Jaga, wounded in the battle, is captured by Mumm-Ra and tortured to get information on the location of the Book of Omens.[11]
September 1. After placing King Claudus's body in a funeral pyre, Lion-O, Cheetara, Tygra, and Lion-O's nursemaid Snarf (38) leave Thundera. Just outside the border, they run into a pair of street urchins in WilyKit and WilyKat, who unofficially join their little group.[12]
September 12. The Thundercats find themselves in a huge briar thicket. They befriend the plant-like Petalars, who live their entire lives in a day. They help the Petalars leave the thicket to carry themselves on the winds to their ancestral homelands. In the aftermath, the Thundercats face Slithe and his Lizards, and are nearly routed due to sheer numbers, but a surviving Panthro (39) arrives in his Thundertank, causing Slithe to retreat.[13]
September 13. The Thundercats infiltrate a mountain being mined by Mumm-Ra's war effort in search of thundrillium fuel for the Thundertank. Panthro has a brief confrontation with Grune. Lion-O earns Panthro's respect.[14]
September 16. The Thundercats reach the Tower of Omens after defeating several deadly obstacles. Mumm-Ra attacks, and nearly slays them, but Jaga, a spirit trapped in an orb by Mumm-Ra, sacrifices himself to stop Mumm-Ra, exploding in a burst of light. Lion-O recovers the Book of Omens.[15]


  • September 9-11. The Sorceress Teela Na sends prince Adam and Cringer to Etheria, where they aid the Great Rebellion, and Adam learns their leader, Adora, is his sister as well as a hero in her own right as She-Ra.5

September 12-13. Adam brings Adora to his parents Marlena and Randor, who are happy to reunite with their daughter. Hordak, having followed the heroes to Eternia, teams up with Skeletor (50) and his associates to capture Adora, and are successful. Skeletor betrays Hordak, sending him back to Etheria. Although He-Man, Battle Cat, Man-at-Arms (49), and Teela (19) make an effort to rescue her, Adora escapes and, as She-Ra, defeats Skeletor and his goons.6
September 14. Adora decides to return to Etheria to liberate it completely from Hordak and his Horde.7


October 5. The Ancient Spirits of Evil send Mumm-Ra on a quest after they cause a spatial rift that draws Third Earth into close proximity to Eternia. Mumm-Ra disguises himself as the Sorceress, and tricks Prince Adam (19), stabbing him through the heart with the Sword of Power. Though dying, Adam uses the Sword to transform into He-Man, and battles Mumm-Ra, but Mumm-Ra escapes with the Sword. The Spirits betray Mumm-Ra, turning him to dust, and allowing Skeletor (51) to take the Sword. While He-Man and the Masters (including Man-at-Arms [50], Teela [20], and Orko [1544]) battle a combined team of Skeletor's goons (Beast Man, Tri-Clops, Trap Jaw, and Evil-Lyn) and Mumm-Ra's (Slithe, Atticus Monkian, Kaynar Jackalman, and Vultaire Vultureman), Skeletor casts a spell and consumes Mumm-Ra's remains, absorbing his power, and allowing him full access to the Sword of Power's might. At the same time, He-Man reverts to his true Adam form, and dies in his father's arms. A triumphant Skeletor, who finds the essence of Mumm-Ra attached to his consciousness, is immediately attacked by Lion-O (19) and the Thundercats (Panthro [42], Cheetara [22], Tygra [22], WilyKit [13], WilyKat [13], and Snarf [39]). Skeletor is a match for them all, but as a group they begin to overwhelm him. Skeletor slashes Lion-O across his left eye with the Sword of Power, leaving a great scar and damaging his eye. Finally, Lion-O uses Skeletor's reflection (a weakness of Mumm-Ra's) in the Sword of Omens to cause him to flee without the Sword of Power. [19]
October 6. The Eternian people gather for the funeral of Prince Adam. The Thundercats come to Eternos, and bring the Sword of Power, and Lion-O presents it to King Randor. Suddenly, the Ancient Spirits of Evil, under the command of a united Skeletor and Mumm-Ra, attack Eternos. While the Eternians and Thundercats work together at evacuation efforts, Lion-O and Cringer (7) take Adam's corpse to Third Earth in a mad attempt to revive him. Cringer, transformed temporarily into a Battle Cat humanoid by the Sword of Omens, fights and defeats Atticus, Kaynar, Beast Man, and Tri-Clops, while Lion-O places Adam in Mumm-Ra's sarcophagus. Adam revives as a berserk He-Man, and Lion-O battles him to a standstill. He restores He-Man's mind with the Sword of Omens. The Ancient Spirits approach Castle Grayskull, and the defenders engage them. With their combined forces, and the help of the Sorceress (47), the four giant demon monsters are defeated. Skeletor and Mumm-Ra then merge (becoming "Mumm-ator") and defeating both groups. Lion-O, He-Man, and Battle Cat return to Eternia, and storm Castle Grayskull, which has already been invaded. Mumm-ator subdues the Sorceress, and begins to access the Orb of Power, but the combined efforts of Lion-O and He-Man brings about the defeat and separation of the villains.[20]
