Trap Jaw fires his arm cannon in a burst of sparks

EVIL AND ARMED FOR COMBAT

Trap Jaw

Trap Jaw is Skeletor's man with a metal jaw and a socket where his right arm used to be, in Filmation's cartoon from its very first episode. Decades later, Mattel's Classics card gave him a name, Kronis, and a past as the rival Skeletor left for dead.

Trap Jaw is the Evil Warrior with a hinged metal jaw and a weapon socket where his right arm used to be. Filmation brought him in with its first episode in 1983, and Mattel's Classics cardback later named him Kronis.

FILMATION, 1983

A socket where his arm used to be

Trap Jaw is in Filmation's He-Man and the Masters of the Universe from the start. In the first episode, "Diamond Ray of Disappearance," shown on September 5, 1983, Skeletor uses his new diamond to summon Mer-Man, Evil-Lyn, Tri-Klops and Trap Jaw for an assault on the Royal Palace, and the episode's cast list gives the voice to Erik Gunden, the name Lou Scheimer used on the show's credits.

Filmation gives him a decent share of the run and casts him as the villain who wants power on his own terms. Robby London's "Double Edged Sword," shown on October 4, 1983, is the clearest example: Trap Jaw goes hunting for the fuel Eternium because it would make him as powerful as He-Man, says so twice in the first act, and finds that the power burns off in minutes. The Eternium is for himself, not for Skeletor.

IN PLASTIC, 1983

Evil and armed for combat

Mattel's figure arrived in 1983, in the second wave of the original line, and its card front reads "Evil & armed for combat." The figure sold the idea better than the words did: the right arm ends in a socket that takes three attachments, a pincer claw, a grappling hook and an energy blaster, and swapping them changes his weapon in your hand. Very few figures in the line had a play feature that was also a character concept.

Mattel returned to the same idea with different wording each time it relaunched him. The 200x line billed him as "Trap Jaw, Evil Mechanical Menace," and the Masters of the Universe Classics card went back to the vintage phrasing for its title.

THE CLASSICS CARD

Kronis of Infinita

The Classics cardback, released in 2010, is one of the longest in the line, and it is the one that gives him a real name: "Real Name: Kronis. Now a powerful Overlord of Evil, Skeletor defeated Kronis breaking his jaw and arm and leaving him for dead." The sentence is clumsier than it means to be: it is Skeletor, not Kronis, who is now the Overlord of Evil.

The rest of the card fills in the arc around that sentence. Kronis served Keldor for years, grew ambitious, raised an army of his own to challenge his master, and lost. The rebuild that followed was done by Tri-Klops, who found him and remade him into Trap Jaw, a man armed with combat weapons and an iron jaw, so the name Trap Jaw only exists after the defeat. On this telling he is a survivor patched together by a colleague after the boss tried to kill him.

The card also places him among the earliest recruits. Keldor freed him from an intergalactic prison at the start of the Great Unrest, before the transformation into Skeletor, which puts him in the same enlistment bracket as Beast Man and earlier than Tri-Klops, whom the Classics cards have joining during one of the Great Unrest's final battles. It also gives him an origin off-world, in the dimension of Infinita.

Questions

Trap Jaw questions, answered

Which He-Man character has a metal jaw?

Trap Jaw. The entire lower jaw is a hinged metal trap, which is the fastest way to tell him from Tri-Klops, the other blue-skinned cyborg among the Evil Warriors.

What is Trap Jaw's real name?

Kronis, from the dimension of Infinita. Mattel's Classics cardback carries it in the Real Name field and uses Kronis throughout the bio prose.

Who turned Kronis into Trap Jaw?

Tri-Klops, according to Mattel's Classics cardback. Skeletor broke Kronis's jaw and arm and left him for dead, and Tri-Klops found him and rebuilt him with combat weapons and an iron jaw.

Was Trap Jaw always loyal to Skeletor?

No. The Classics card says he served Keldor for years, then raised an army of his own to challenge him. Skeletor won that fight. Filmation's "Double Edged Sword" runs the same idea on a smaller scale, with Trap Jaw hunting Eternium to give himself power equal to He-Man's.

What does Trap Jaw's arm do?

It takes interchangeable attachments. The vintage 1983 figure shipped with a hook, a claw and an energy blaster that clip into the arm socket, and the cartoon uses the same idea.

Who plays Trap Jaw in the 2026 movie?

Sam C. Wilson, in a practical suit built by Barrie Gower.

Was Trap Jaw in the 1987 live-action movie?

No. Trap Jaw is not in Cannon Films' 1987 Masters of the Universe.

What is the difference between Trap Jaw and Tri-Klops?

Mostly color and gimmick, which is why they get mixed up. Both are blue-skinned, armored Evil Warriors. Tri-Klops has three eyes on a rotating visor; Trap Jaw has a hinged metal lower jaw and a weapon-socket arm. Mattel's Classics bios also make Tri-Klops the one who rebuilt Trap Jaw.

Is Trap Jaw a robot?

No, a cyborg. Mattel's own species line for him reads "Cybernetically modified Eternian": under the mechanical jaw and the weapon-socket arm is a living Eternian body, not a machine built from scratch.

Who built Trap Jaw's look for the 2026 movie?

Barrie Gower, the special-effects designer who also built the practical Skeletor suit for the same film.
