The main element is Adora. She is the core character who becomes She - Ra. Another important part is the Sword of Protection. It's what triggers her transformation. Also, the Horde as her former group plays a role in setting the contrast between her old life and her new heroic identity.
She - Ra's origin has to do with her connection to the magical world of Etheria. Adora, who would become She - Ra, was raised in the Horde, not knowing her true heritage. The Sword of Protection was a key element. When she grasped it for the first time, she underwent a transformation. She - Ra is not only strong physically but also has a strong moral compass which she uses to fight for justice in Etheria. Her origin story sets the stage for all of her heroic deeds in the series.
I'm not entirely sure which 'ra' you specifically mean. There could be many things named 'ra' in different contexts, like Ra in Egyptian mythology. In Egyptian mythology, Ra was the sun god. He was often depicted as a man with a falcon head. He was considered one of the most important deities, as he was associated with the sun, which was crucial for life in ancient Egypt.
She-Ra isn't based on a real story. It's an imaginative work that brings to life a fantasy world and characters through the creators' imagination and storytelling skills.
It could be about She - Ra exploring a new, uncharted realm filled with strange creatures and magic. Maybe she has to team up with old foes turned allies to defeat a powerful, emerging evil that threatens all of Etheria.
In the original She - Ra story, Adora / She - Ra is central. She - Ra's sidekick, Swift Wind, is also a notable character. He's a talking horse with magical abilities. Another main character is Entrapta, a brilliant but somewhat misunderstood scientist who gets involved with the Horde. And of course, Catra, who has a complex relationship with Adora.
There could be a new group of rebels from a previously unmentioned part of Etheria. They might have unique powers and abilities that She - Ra has to learn to work with. For example, a character who can control the elements in a very different way from what we've seen before.
The original She - Ra story is set in a fantastical world called Etheria. Adora, who was raised by the Horde, realizes that their ways are wrong and joins the Rebellion. As She - Ra, she has a sword that gives her special powers. Her archenemy is Hordak, the leader of the Horde. The story also explores themes like self - discovery and the power of love and loyalty. There are many memorable characters in the story, each with their own unique abilities and personalities.
