The Once and Future Duke

David, the young Duke of Abra and a childhood friend of Adam and Teela's, turns up at the Royal Palace still a boy, even though decades should have passed since they last saw him, and with no memory of who he is. The mystery traces back to his uncle, Count Marzo, who has used a magic ring to trap David in childhood and keeps a fountain, the Well of Forgetfulness, that can drain a person's memory entirely.

Marzo sends his henchman Chimera and a pair of Pterror-dactyls to keep He-Man, Teela, and Battle Cat from reaching David's homeland and uncovering the truth. The searchers push through an icy mountain pass and fend off Chimera's attacks as they track down the ring that holds David's years hostage.

Cornered at last, Marzo tries to use the Well of Forgetfulness against David again, but the trap turns on its creator: Marzo himself tumbles into the well and loses his own memory. With Marzo defeated, the ring's hold is broken, and David gets back both his memory and the years of his life he had been robbed of, reuniting with Adam and Teela as the man he was always meant to become.

He-Man: "Swimming is fun and good for you, but going in the water can be very dangerous... on your planet as well as mine! But there's no chance that you'll lose your memory as Orko did, but the threat of drowning is very real. That's why it's important to be aware of the rules of water safety. Don't play jokes in the water. Always be sure to swim in an area where an adult is watching you. And never swim alone. Go with a friend. Keep your swimming safe... and live to swim another day!"

Orko: "Well, there's one thing I want you to forget: the way I disappeared for you before. I've got it down perfectly now. Watch! Geebie, feelie, filee, foe, as you watch me, here I go... Oh, well."

Memory is the thing this show rarely bothers to question. He-Man forgets nothing, Skeletor's plans recur without him learning a lesson from the last one, and Eternia resets itself every twenty-two minutes. "The Once and Future Duke" is the rare Filmation script that makes forgetting the actual subject. Not just the device that gets a character out of a scene, but the engine of the plot itself, and that is what keeps it watchable past its monster-of-the-week shape.

The hook is simple: a boy who should be a grown man shows up at the palace gate, and nobody but Teela recognizes him. David of Abra was Adam and Teela's childhood friend, and somewhere between then and now he has lost not just his memory but two decades of his own growth, trapped as a child by Count Marzo's Ring of Remembrance. Phyllis and Robert White's script treats that as a genuinely strange premise rather than a throwaway one, and Lou Zukor's direction leans into it: David spends most of his screentime flinching from adults he should know, and the animation gives him the smaller gestures of someone who has been told his whole life does not add up. It is a stranger image than this show usually risks, a child's face carrying a man's missing years, and we don't get it explained away quickly.

Count Marzo gets more to do here than villain-of-the-week duty usually allows. His magic has a function rather than a generic glow; he trades on names and favors instead of brute force, and he works his fountain and his Well of Forgetfulness like tools built for exactly this job. He sends Chimera to do the dirty work precisely because sending himself would cost him something. When he loses his own memory at the episode's close, tumbling into the well he weaponized against David, the show earns the irony instead of just stating it. Everyone here is defined by what they do and do not remember, down to Orko's running gag about forgetting his own vanishing trick.

The weak link is pacing in the middle third. Once He-Man, Teela and Battle Cat set out to track down the ring, the episode falls into the standard obstacle course: an ice creature here, a Chimera chase there, each dispatched in under a minute with little connective tissue back to the David plot that opened the show. The ice-mountain detour plays more like padding than peril, a fight included because the format expects one rather than because the story needed it. This is the kind of scene the show could have cut in half without losing anything, and its absence would have left more room for David, who all but vanishes from his own episode while the adventure runs its course without him.

Linda Gary's double duty as Teela gives the episode its emotional ballast when the plot wanders; her scenes comforting Orko and cornering Count Marzo both land with more weight than the dialogue alone would suggest. Erika Scheimer's young David, uncredited, carries the harder job, playing confusion without ever tipping into cartoonish helplessness. The closing scene, where David gets back his name and the years he lost, plays the reunion straight rather than rushing to the next gag. That's more than most episodes bother to do for a one-off guest character.

"The Once and Future Duke" will not top anyone's list of the show's best hours, and its middle stretch drags exactly where a tighter edit would have helped. But it does something this show rarely attempts: it builds a villain's defeat out of his own methods, and it gives a disposable guest character an ending that actually resolves the strangeness it opened with. We'll take that trade.

1. Behind the scenes: Script was approved June 3, 1983 and final script revision was completed June 30, 1983. The character models were finalized on August 3, 1983. Count Marzo is one of the rare Filmation based villains who makes more than one appearance. He returns in The Eternia Flower and Search for a Son and so does his henchman Chimera, although he was redesigned. Marzo also uses Pterror-dactyls again in his third appearance, this time colored blue rather than brown. The script identifies Marzo's vehicle as a 'Doom Buster' even though a different design was later used for the vehicle of the same name used by Skeletor.
2. The Vaporizer weapon that Marzo uses to make Man-At-Arms develop amnesia was released as a toy in 2018 as part of Super7's line of action figures. It was included with several other weapons that came with a Filmation style action figure of Man-E-Faces.[[1]](#cite_note-1)
3. Continuity: Count Marzo uses the Well of Forgetfulness again in Search for a Son, although it's location on Eternia has changed. The animation of He-Man blowing away the freezing fog would be used again in The Rarest Gift of All, Betrayal of Stratos, A Trip to Morainia, Just a Little Lie, The Greatest Show on Eternia and Happy Birthday Roboto. The background plates used for Marzo's Castle were originally used as Queen Elmora's throne room in She-Demon of Phantos and would appear again in The Witch and the Warrior as the interior of Kothos' stronghold. The character model of the adult David was reused as an extra on a balcony in the She-Ra: Princess of Power episode The Red Knight.
4. More continuity: The sequence of Count Marzo raising both his hands and firing blasts at He-Man is reused in The Eternia Flower.
5. Animation errors and goofs: When He-Man blows away the fog, the background is not Count Marzo's castle but the Evergreen Forest with the Royal Palace visible on the far left.
6. A noble duke is cursed by Skeletor's magic. He-Man must navigate the politics of an Eternian fiefdom to break the spell.
