WHERE HE COMES FROM

The man who sent for a hero

Master Sebrian was written for The New Adventures of He-Man, the 1990 Jetlag Productions series that takes He-Man forward to the planet Primus, where Flogg's Mutants of Denebria keep battering at the shield over the planet. The 1990 show sits outside the classic canon here: the Filmation He-Man stays the reference point, and Sebrian belongs to what came after.[1]

The series begins with his decision. In Jack Olesker's premiere, "A New Beginning," he goes before the Inner Council, the gathering of great minds that holds the shield up, and tells them what the people of Primus do not know: that the council is shrinking with every attack, and the shield cannot take another. His answer is a time vessel the scientists have invented, a trip into the distant past, and the power of the good and the way of the magic brought back to Primus. "It may be our only chance to save ourselves," he says, and the council, addressing him as its leader, lets him send Captain Hydron and Flipshot.[2]

From then on he is the old man at the center of the Primus side: bald on top, long white hair down his back, a blue robe and a gold chain, and a forked wooden staff he is seldom without. His assistant Mara runs his errands and his diplomacy, the scientists bring him their inventions, and He-Man comes to him for orders, which for a hero who spent the Filmation years taking advice from the Sorceress is not much of a change.

[2] ^ The English subtitles spell his name several ways, Sebrion and Sabrian among them. Sebrian is the spelling on Wikipedia and in IMDb's credits.

THE SIGNATURE EPISODE

The Test of Time

Richard Merwin's "The Test of Time" opens with Sebrian out of breath. "Mara, please slow down. I'm not as young as I used to be," he says, and when she reminds him that he once told her age is all in the mind, he agrees: "Quite true, Mara. Except when it's my mind." A radiation storm has knocked out the anti-gravity system holding up the floating city of Levitan, the city is sinking, and the beryllium ore that would save it has been hijacked by the Mutants, who set its trader adrift.

He-Man brings the trader in, and he turns out to be Treylus, who went to school with Sebrian and greets him with "Sebrian, you old bookworm!" Treylus is everything the scholar is not, a spacefaring adventurer who puts his own youth down to hard work, hard play and all the adventure he can find, and when the rescue plan is made he takes the astrosub to the Mutant base on Denebria himself. Sebrian says he will stay behind with the scientists. Treylus agrees that a man his age should not risk getting hurt, and Sebrian, alone with Mara, decides that he will just have to teach Treylus a lesson.

So he stows away. Halfway to Denebria a startled Treylus asks what he is doing there, and Sebrian answers, "I'm beginning to wonder myself." Inside the Mutant base it is the scholar's trick that saves them. Flogg's side orders its fighters to stop the escaping cargo ship, and Sebrian, at a synthesizer, sends out an order of his own to cease firing and return to base, so that the Mutant leaders end up arguing over who said what. "A simple synthesizer adjustment," he explains, and then, a moment later, "It was nothing a younger man couldn't have done. Almost as well."

By the closing scene the change has run slightly too far: Sebrian invites himself along on the Guardians' next patrol, and one of them decides he prefers the old Master Sebrian. It is a small, warm story, and it gives Antony Holland more to do than usual.[3]

[3] ^ Antony Holland is credited as Master Sebrian in IMDb's full credits for "The Seeds of Resistance", "Collision Course", "Zone of Darkness" and "The Test of Time", where his name is spelled Anthony Holland, and Wikipedia's cast list for the series agrees.

THE SECOND ANGLE

A leader who trusts

Sebrian's instinct, as a leader, is to trust people, and the series tests it more than once. In Jack Olesker's "The Gift," Flogg calls the Inner Council to talk about ending the war and offers a peace gift, the furry Zeps. Some voices on the council want nothing to do with it; Sebrian argues that the two sides must try to trust each other or there can be no peace, and it is hard to say he is wrong, but within days the Zeps are everywhere on Primus and then turn into Anadroids. By the end he is handing He-Man the key to the shield and sending him into the wilderness with Mara.

"Council of Clones" plays the same note harder. The council is exhausted after days of attacks on one sector, Skeletor lets the Primans capture a supercomputer, and He-Man warns that anything from Skeletor can bring nothing but evil. Sebrian takes it anyway: "It's a chance we'll have to take," and, of the machine's clone program, "Trust me, it's perfectly safe." The cloned council strengthens the shield and then brings it down. He-Man's warning comes true, but so was the exhaustion that pushed Sebrian into the gamble, and the episode ends with him in bed, ordered to rest.[4]

When he is cornered, the same steadiness is a weapon. In "Skeletor's Victory" he is the Mutants' prisoner, and when Skeletor moves to smash the Vasionic Resonator, Sebrian stops him with one piece of information: the machine was built from unstable material, and wrecking it would set off a chain reaction across half the galaxy. In "The Battle for Levitan" it is Sebrian who tells Adam to accept Skeletor's demand and surrender, because every Mutant in one place is an opening Primus can use.

[4] ^ The He-Man wiki notes that "Council of Clones" is one of the few times in the series that the Sorceress speaks to Master Sebrian.

THE FILMS

Off the big screen

The films have had no place for him. The 1987 Masters of the Universe never leaves Eternia and Earth for Primus, and the 2026 cast on the film cast page does not include him.

IN PLASTIC

No figure yet

Mattel's New Adventures line was built around Guardians and Mutants who could fight each other, and the old man who ran the planet was left out.[5]

[5] ^ As far as we can find, Mattel has never made a Master Sebrian figure, in the 1989 New Adventures line or since.
