Headcanon: Gogeta (After he became his own person) senses a powerful Kai energy in another universe and uses instant transmission (Which now allows him to travel to different universes). When he arrives on the planet, he's disgusted at the ways of this planet and is about to leave when he hears malicious laughter and a cry for help. He follows it and sees a sun-haired woman surrounded by a group of men with one choking her. Gogeta gets enraged by this and punches the man that was choking her so hard, he dies instantly. Then the rest of the men try to attack Gogeta but are blasted to atoms immediately. After killing the group, Gogeta looks at the woman, who looks scared, and asks if she's alright. She then looks surprised and asks if he's going to hurt her. He says "No" and he tells her his name and that he's not from this planet or universe. She tells him about how harsh her planet is and that her name is Eliane Taiyou. After sensing the powerful Kai energy that he's been following in her, Gogeta tells her about his universe and Earth and then asks Eliane if she wants to live on his universe's planet. When Eliane realizes that he genuinely cares about her, she accepts his offer, and Gogeta uses instant transmission to take her to her new home. When they get there, Gogeta introduces Eliane to the rest of the Z-fighters, and tells everyone about her, and the Z-fighters accept her into their group with open arms. After living on Earth and awakening as Sailor Galaxia, Eliane decides to use her newfound powers for peace and justice.
