The lost sibling (Superhero-based)

Raylier was young when her family was separated. An 8 year old girl to be specific. After her spaceship she's been living in with her parents and sister for her first years blew up, her parents died and her sister was sent to planet Earth, while she was sent to a planet full of space junk.

After almost living there for 2 weeks, she helped an enchanted book and befriended the personified item. They lived there for about 5 years before leaving to explore other planets.

Upon arriving on Earth, the duo found their way over to Arizona, USA, months after landing on Sydney, Australia. They found themselves face to face in a battle to stop an evil organization, led by the villain Harley Quinn, in their goal.
Once Raylier killed Harley, the rest of the team came and outnumbered Raylier and Enchanix in an unfair battle. Raylier learnt about her powers and quickly got control of them in order to win the battle.

After stopping the team (and destroying them), Raylier and Enchanix made their way over to California, USA, meeting up with Raylier's sister, Supergirl.

They switched out information, Raylier and Enchanix decide to work as professeurs in research about the villain organization(s) while travelling the different dimensions, alongside their exploration.
