List of He-Man and the Masters of the Universe characters

The Masters of the Universe franchise, created in 1982 as a toyline by American company Mattel, contained many characters in its various incarnations as a toyline, the television series He-Man and the Masters of the Universe, a German series of audioplays, The New Adventures of He-Man, He-Man and the Masters of the Universe (2002), Masters of the Universe: Revelation and He-Man and the Masters of the Universe (2021) and the films The Secret of the Sword, He-Man & She-Ra: A Christmas Special, and Masters of the Universe.

All of these characters were released in the vintage Mattel toyline.

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, however, 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.

In the 2002 series, Cringer occasionally meows like a kitten, but also shows bravery from time to time, including rescuing Prince Adam from falling to his death in Snake Mountain ("Council of Evil"). Battle Cat's rescue of Queen Marlena ("Of Machines and Men"), based on knowledge only Cringer would have, causes Marlena to wonder about Battle Cat's identity.

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, and David Kaye in the 2021 series.

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.
