The character of He-Ro makes his first animated appearance. He was planned for the original toy line, but went unproduced until the Masters of the Universe Classic line in 2009.
The character named Wun-Dar is based on a mysterious, brown haired mail-away version of the He-Man action figure that fans named "Wonder Bread He-Man" because it was thought to have been associated with a promotion by that brand. The name Wun-Dar was given to it when the character was released as an exclusive in the Masters of the Universe Classics line in 2010.
The 1987 toy dinosaur Bionatops makes its first animated appearance. Three Turbodactyls can also be spotted in the sky.
The concept of Preternia was first mentioned in the final series of Minicomics that came with the original Masters of the Universe action figures, in which it was the name given to describe the planet Eternia in ancient times.
Kevin Smith said that this episode was a homage to the Masters of the Universe movie.
