In Masters of the Universe, the main fictional planet is Eternia. This planet has various landscapes, from lush forests to barren deserts, and is home to powerful heroes and villains.
In the novel, The Desolation of the Universe, the ruler of the Desolation of the Universe was known as the " Heavenly Emperor ". He was a powerful god with the power to rule the entire Desolation of the Universe.
The Sith Universe Master was uncertain because the novel did not mention the existence of the Sith Universe or its master. It was possible that the Sith Universe was a larger universe and the Celestial Thearch was only a part of the gods or leaders within it. However, if you want to know more about the Sith Universe, it is recommended to read related novels or online articles.
One interesting storyline could be exploring the backstories of the minor characters in the Masters of the Universe universe. For example, delving deeper into the origin of Orko, his life on his home planet before coming to Eternia. Another could be a story where He - Man and Skeletor have to team up against a greater evil that threatens both their interests. This would flip their usual dynamic on its head.
He - Man is obviously one of the most popular. He's the main hero, so many fanfictions revolve around his adventures, his battles against Skeletor, and his growth as a character. Skeletor is also very popular. His evil nature and his constant scheming make for great plotlines. People like to write about his attempts to take over Castle Grayskull and his interactions with his minions.
I recommend the following two novels to you:
1. In <<The Glorious Era of the Supreme One>>, the main character had amazing cultivation in different worlds and eventually became a universe controller.
2. "There's a Universe Ocean in My Palm." The protagonist gained the ability to control the universe in his palm and eventually became the master of 129,600 universes.
I hope you like this fairy's recommendation. Muah ~😗
In general, Valiant Comics have multiple separate universes. The characters and events in one series don't directly interact with those in others. This allows for more diverse and unique storytelling.
