Rock People / Comet People
Sometimes referred as Geolonians or Comet Warriors, the Rock People are Humanoids, who have the power to transform into rocks or comets. Rock People can use their blazing armor to temporarily blind attackers in battle. When the Rock People are in danger, they use their ability to transform into their rock forms to drive back the enemy!
POP Filmation Cartoon Continuity:
As the toy line's accompanying cartoon series, He-Man and the Masters of the Universe had been cancelled by the time the Rock People's action figures were released, they instead appear on its spin-off series, She-Ra: Princess of Power. They are introduced in the episode "The Rock People" as members of a scouting party from the planet Geolon, who are looking for a new home as their planet is due to explode. In-keeping with their mini-comic portrayal, they are a peaceful race who refuse to fight, but are left with no other choice but to do so when Rokkon is captured by Hordak. Although initially feeling Etheria is too violent for their race, after realizing that they share a common bond with She-Ra and the Rebels desiring to live in peace, they eventually choose to settle in a peaceful region of Etheria, known as Spikeheart.
This episode features a third Rock Person in addition to Stonedar and Rokkon: the female warrior Granita, who was planned as an action figure by Mattel, but the idea was scrapped when they decided three figures with the same action feature was too many. Stonedar and Granita appear in another She-Ra episode, "The Light of the Crystal" which also introduces another female rock warrior by the name of Facet.
Vintage POP Mini-Comic Continuity:
The Rock People are introduced in the Mattel mini-comic "Rock People to the Rescue", in which Stonedar and Rokkon come to Eternia specially to aid He-Man in his battles against Skeletor. Later mini-comics, such as "Escape from the Slime Pit" show that their race had settled in a village on Etheria rather than Eternia, presumably to tie in with their appearance on the She-Ra series, and are a quiet, peaceful race, who refuse to fight back when attacked by Hordak as fighting is not their custom.
Masters Of The Universe Classics:
When the peaceful Rock People refused to submit to Horde Prime's leadership. he unleashed a powerful light storm, which drove some of the Rock People from their planet and hurled them through space. Blasting through several untamed star bands, several Rock People, including Stonedar, their heroic leader, arrived on the magical planet of Eternia, where the Rock People allied themselves with He-Man and the Masters Of The Universe.
