Heroic Warriors Vintage toyline characters (1982–1988) All of these characters were released in the vintage Mattel toyline.

Battle Cat / Cringer Battle Cat is He-Man's faithful feline companion, an armored green tiger who carries him into battle. When He-Man is in the form of Prince Adam, Battle Cat is Cringer, the royal pet. Both Cringer and Battle Cat are green with orange stripes, but Battle Cat is much larger and more muscular. In the original 1980s series, Cringer speaks and is afraid of just about everything, hence the name.

In The Toys That Made Us, then-marketing VP of Mattel Paul Cleveland recounts the story that while the decision was made for He-Man to have some sort of vehicle, they no longer had the budget to be able to produce one; the decision was then made to repurpose a tiger from the Big Jim toy line. The tiger was not the same scale as the He-Man figure, and compared to He-Man, was about the size of a horse. Cleveland, however, insisted it to be used, even after artist Tony Guerrero made a green version in an attempt to discourage Cleveland, who instead approved of the color change and suggested putting a saddle on it, which resulted in Battle Cat's final design.The Toys That Made Us; Episode 3

The Masters of the Universe Classics toyline stated that Cringer was part of the Green Tiger Tribe who was saved from a Para-Nekk by a younger Prince Adam and became his devoted companion.

Battle Cat also appears in the tower defense game Bloons TD 6 as a power which can only be obtained in a bundle or in a quest by the name of "By the Power of Battle Cat!"

Cringer and Battle Cat are voiced by Alan Oppenheimer in the 1980s series, Stephen Root in Masters of the Universe: Revelation, David Kaye in the 2021 series and Tom Wilton in the 2026 film. In the 2026 film, Cringer/Battle Cat replaces Leo the Lion in the Metro-Goldwyn-Mayer pictures logo using Leo’s trademark roar tracks.

Buzz-Off Buzz-Off is a humanoid bee, established in the Filmation series as the leader of a tribe of Bee People. The 2002 series develops this further, giving Buzz-Off's people a name—the Andreenids—and establishing Buzz-Off as the captain of the defense force of their kingdom of Andreenos, in the Mystic Mountains. He is considered a newcomer to the Masters of the Universe by Ram Man and, while loyal to the defenders of Eternia, is equally loyal to his Queen, at times using his free time to fetch honey berries for her. Buzz-Off has a distrustful nature and tends to hold grudges, but his camaraderie with Stratos paved the way for peace between the peoples of Andreenos and Avion.

Buzz-Off is voiced by Alan Oppenheimer in the 1980s series and Brian Dobson in the 2002 series.

Buzz-Off was voted 1st out of 7 in the 7 Stupidest He-Man Characters by Total Film.

Clamp Champ Clamp Champ is a Heroic Warrior who wields a large handheld grabbing device as his primary weapon. He was the only black character to have an action figure in the vintage toy line. Several black characters (such as Zodak and Dekker) have since been released in the 200X and Classics toy lines.

The character was planned for usage in the 2002 series as a replacement for Man-At-Arms who is turned into a Snake-Man, but the series was cancelled before he could be featured in it.

Clamp-Champ made his TV debut in Masters of the Universe: Revelation.

In the Masters of the Universe Classics toyline, Clamp Champ's real name is Raenius. He started out as King Randor's bodyguard before becoming the new Man-At-Arms after Duncan was turned into a Snake Man.

Clamp-Champ is voiced by Method Man in Masters of the Universe: Revelation.

Extendar Extendar is a mechanized being and Master of Extension. He appeared in the Masters of the Universe comic series, having been created after the Filmation series finished. Extendar was an Eternian who was captured and turned into a cyborg against his will by Hordak, only to escape before he could be brainwashed into serving his captor.

The Masters of the Universe Classics toyline introduced Extendar as a knight who was captured by Hordak and thrown into the experimental matrix which grafted cybernetic parts to him.

Fisto Fisto is an extra-strong warrior with a metallic right hand. In the original series, he was the caretaker of a forest and was hesitant to join in the conflict against Skeletor. He was later appraised by both his fellow Eternians and an alien race as second in strength only to He-Man.

In the 2002 series, he is the last to join the Masters of the Universe and is Man-At-Arms's older brother. The brothers became estranged during the Great Unrest, when Fisto allegedly deserted Randor's forces. Fisto comes to the aid of He-Man and the Masters, using his giant fist to free them from the rocks that had entrapped them in a cave-in. This act shatters his hand, which Man-At-Arms replaces with a larger, metallic hand. The 2002 figure was packaged as "Battle Fist" due to a conflict of copyrighted name with another toy line, but the character was still called Fisto in the animated series.

The Masters of the Universe Classics toyline still listed Fisto as Man-At-Arms's older brother who was rendered amnesiac when helping King Miro during the Great Unrest. Having shattered his right hand saving the Masters of the Universe from a trap set by the Snake Men, Man-At-Arms replaced that hand with a robotic hand.

Fisto is voiced by Lou Scheimer in the 1980s series, Mark Acheson in the 2002 series, and by Ralph Garman in Masters of the Universe: Revelation. Fisto is portrayed by Jóhannes Haukur Jóhannesson in the 2026 film.

Stridor Stridor is Fisto's horse and faithful companion. He made one appearance in the Filmation series in the episode "Origin of the Sorceress", in which he was a mechanical horse built by Man-At-Arms who later developed consciousness, leading Man-At-Arms to release him into the wild. Stridor's toy was available packaged with Fisto, as well as separately, and much of Mattel's box art depicted the character of Fisto riding atop Stridor. Stridor later appeared in several Masters of the Universe comic adaptions and toy reissues following the original Filmation series. The character became one of the more recognizable animal companions in the franchise due to his mechanical design and association with Fisto. Updated versions of Stridor were also released as part of later toy collections, including the Masters of the Universe Classics line.

Gwildor Gwildor is a dwarf-like Thenurian and inventor of the Cosmic Key. He debuted in the Masters of the Universe film, where Evil-Lyn tricked him into giving her the Cosmic Key so that Skeletor can invade Castle Grayskull.

In the Masters of the Universe Classics toyline, Gwildor is a Vejulian Gwitthrol Troll from Tundaria. He attended Grimhammer University in Eternos and studied under many of Eternia's great inventors, archaeologists, and magicians.

Gwildor is portrayed by Billy Barty in the 1980s live-action film and voiced by Ted Biaselli in Masters of the Universe: Revolution.
