King Randor rules Eternia from the palace at Eternos. Mattel's own name for him is Randor of the House of Miro, and its cardbacks are clear that he was not born to the throne: he was the second son, given the crown by the Council of Elders.
Not the heir
The single most useful thing Mattel ever wrote about Randor is that he should not have been king.
Both Masters of the Universe Classics cards agree on it. He is King Miro’s second-born son. His older brother was removed from the line of succession. The Council of Elders then set aside Eternian law and gave the crown to Randor as a reward for ending a war. Every version of the character that plays him as a slightly stiff, dutiful, rule-following monarch is playing a man who holds his office by exception rather than by right, whether or not the writers knew it.
The vintage figure arrived very late. Randor was a 1987 release, sold through a mail-away offer near the end of the vintage line, with the card front subtitle “Heroic ruler of Eternia”. By then Filmation had been running him as a supporting character for four years, voiced by Lou Scheimer under the pseudonym Erik Gunden, across 59 of the 130 episodes.
Two Classics bios, and where they diverge
Mattel wrote Randor twice for the Classics line: once for the base figure in 2009 and again for Eternos Palace King Randor. Both carry the card title “Heroic Ruler of Eternia” and the real name “Randor of the House of Miro”. Neither is a reprint of the other, and the differences matter.
The base card opens:
Real Name: Randor of the House of Miro. King Miro’s second born son, Randor came of age during the Great Unrest, a time when conflict returned to Eternia following the Count Marzo Uprisings and the subsequent betrayal by his half brother Keldor.
From Mattel’s Masters of the Universe Classics cardback. The rest of that card has Randor appointed captain of the guard after his father disappears, leading Miro’s troops against Keldor’s rebellion, ending the war by fatally wounding Keldor and locking the evil warriors behind the mystic wall, and being made King by the Council of Elders for it.
The Eternos Palace card tells the same story differently, and opens:
Real Name: Randor of the House of Miro. Shortly after his father was thrown into Despondos by Count Marzo, Randor’s older brother was banished from the Royal Palace, leaving Eternia without a king.
Also Mattel, also Masters of the Universe Classics. That card goes on to keep Randor as Captain of the Guard, have him best Keldor in single combat and mortally wound him, order a mystic wall erected to bind Keldor and his warriors to the Dark Hemisphere, and receive the crown from a Council of Elders that agreed to set aside Eternian laws of kingship despite Randor not being the first born.
Four things separate the two cards.
What happened to King Miro. The base card says only that his father disappeared. The Eternos card is specific: Miro was thrown into Despondos by Count Marzo. Not a contradiction so much as one card filling in what the other left vague, but if you are citing a source for Miro’s fate, it is the Eternos card and not the base one.
Who the older brother is. The base card names Keldor as Randor’s half brother and Randor as the second-born son. The Eternos card says Randor’s older brother was banished from the Royal Palace, then in the next clause treats Keldor as a separate returning exile. Read one way, the banished older brother is Keldor. Read another, the cards imply a third son. Mattel never clarifies it, and we are not going to.
How Randor beat him. The base card has Randor fatally wound Keldor and lock the evil warriors behind the mystic wall himself. The Eternos card has him win in single combat, mortally wound Keldor, and then order a wall erected. Whether Randor built the wall or commissioned it is a small thing, but the two cards do not say the same thing.
Fatal or mortal. The base card says “fatally wounding”. The Eternos card says “mortally wounded”. Skeletor’s own Classics card opens with Keldor “Mortally wounded in battle with his half-brother Captain Randor”. All three stop short of saying Keldor died, and they have to, because it is Hordak’s intervention immediately afterwards that turns the dying Keldor into Skeletor. Randor’s defining act is a killing blow that did not kill.
There is a nice generational echo in the base card that most summaries skip. Randor’s post before the crown was Captain of the Guard, which is the exact rank Teela later holds under him.
Queen Marlena, who also has two bios
Randor’s marriage is the other place Mattel contradicts itself, and it does so in a way that changes the shape of the story.
Marlena has two Classics cards for the same person. Queen Marlena, “Heroic Queen of Eternia”, and Captain Glenn, “Heroic Galactic Adventurer”. Both give her real name as Marlena Glenn.
The Queen Marlena card opens:
Real Name: Marlena Glenn. An explorer from planet Earth, Marlena traveled with two companions in an experimental warp ship through a dimensional rift.
From Mattel’s Masters of the Universe Classics cardback. The rest of it has her crash on Eternia as the only survivor, rescued by a young Captain Randor, falling in love and staying as his wife and later Queen. It then says she is “well aware of both Adam and Adora’s dual identities and is proud of her warrior twins” while her children do not suspect it, and notes that she has been trained by Duncan and Clamp Champ and has led Randor’s armies into battle.
The Captain Glenn card covers her life before that: a space captain searching the stars for fuel for Earth, a crack shot who favours a Higuchi 114 laser rifle, an assignment called Project Photog, and a volunteer flight through what this card calls a black hole. It closes by saying that late in life she used the power of the Cosmic Key to return to her homeworld.
The two cards disagree on the basic facts of the crash. One says she went through a dimensional rift, the other a black hole. One says she travelled with two companions, the other with a crew. The Queen Marlena card says she was the only survivor; the Captain Glenn card never mentions losing anyone. Both are Mattel. Neither is more official than the other.
What both agree on, and what reframes Randor entirely, is the timing of the rescue: it was a young Captain Randor who pulled her out. He met his wife while holding the same rank he held when he fought Keldor, before the crown, before the Elders’ decision. The marriage predates the kingship.
And then the line that no adaptation has ever fully used: Marlena knows. Mattel’s own card states she is aware of both her children’s dual identities and proud of them. Randor, on his own cards, does not know. The palace’s running joke about a prince who is never around during an emergency has, in Mattel’s canon, exactly one adult in on it, and it is not the king.
After Filmation
Michael Donovan voiced Randor in the 2002 series, which is also where the half-brother relationship with Keldor was made central rather than a line of cardback text. Diedrich Bader plays him in Revelation, where the material leans hard on a father who believes his son is dead. Roger Craig Smith voices him in the 2021 Netflix animated series.

More on the 2026 Masters of the Universe film
Who is He-Man's father?
King Randor, ruler of Eternia, husband of Queen Marlena and father of Prince Adam and Princess Adora. Mattel's full name for him is Randor of the House of Miro.
Was Randor born to be king?
No. Both Mattel Classics cards say he was King Miro's second-born son. The Eternos Palace card is explicit that the Council of Elders "agreed to set aside Eternian laws of kingship" and gave him the crown "despite not being the first born", as a reward for ending the Great Unrest.
Is Skeletor really Randor's brother?
Half brother, on Mattel's own cardbacks: Keldor, who Randor mortally wounded in the duel that ended the Great Unrest, and who Hordak then transformed into Skeletor. The 2002 series is where that relationship became a driving plot element rather than packaging text.
Does Randor know Adam is He-Man?
Nothing on Randor's cards says he does. Queen Marlena's card says she does, and that neither child suspects it.
Where is Queen Marlena from?
Earth. She was a space captain, and Mattel gave her a second card under her Earth name, Captain Glenn, covering the career that ended when she crashed on Eternia.
Who plays King Randor in the 2026 movie?
James Purefoy, in that role only. Idris Elba plays Man-At-Arms.
