The Rebel Alliance as a whole could be her allies. They are always looking for new and unique individuals to help in their fight against the Empire. The girl from Earth, with her different perspective and skills, could contribute to the Alliance's cause, whether it's in battle strategy, diplomacy, or something else entirely.
Luke Skywalker could be a great ally. He has experience in training new Jedi and would likely be intrigued by the girl from Earth. He could offer his guidance and wisdom in helping her understand and control her connection to the Force.
Luke Skywalker would be a great ally. Since he was also trained in the ways of the Jedi by Obi - Wan, he would likely feel a connection to Obi - Wan's daughter. He could offer her guidance in using the Force and share his own experiences. Another potential ally could be Chewbacca. He's loyal and strong, and his knowledge of the galaxy could be very useful for her. He could help her travel safely through different planets.
He might have some underworld contacts as allies. People who are also outcasts in the galaxy and see value in aligning with a powerful Sith like Darth Maul.
Darth Maul could be a great character. His unique appearance and his thirst for power would make him an interesting addition to a Sith harem. He could be the enforcer, using his double - bladed lightsaber to protect the group.
A young, tech - savvy orphan who has a natural ability with the Force but doesn't know it yet. They could be living on a war - torn planet and get discovered by a wandering Jedi. Another could be a grizzled veteran of some other conflict who decides to join the fight in the Shadow Wars for personal reasons.
Maybe some unexpected allies could emerge. For instance, other dark mages who oppose Zeref's actions for their own reasons. They might see Natsu as a valuable asset or simply dislike Zeref's overbearing ways. Another potential ally could be a powerful spirit that Natsu has befriended in the past. Spirits often have unique powers that could be useful in the fight against Zeref.
Elijah could be on their side. He is Klaus' brother and might understand the importance of the baby, especially if he sees it as a way to keep Klaus in line or to bring about a new era of peace among the different supernatural species. He could use his diplomatic skills to protect the baby from threats.
Raoul could also be an ally. Despite his past with the Phantom, he might see the daughter as an innocent and want to help her. He could use his influence in society to shield her from the negative attention that might come her way once her identity is known.
His mother Tsunade could be one of his first and most important allies. She would surely use her influence and skills to protect and guide him. Shizune could also be an ally, as she has been with Tsunade for a long time and would likely support the OC. Additionally, Naruto could be an ally, as he is known for befriending and helping out those in need in the ninja world.
Another Kamen Rider from the same series who has a different view on justice could be an ally. They might see that Cronus's power could be used for good if guided in the right direction.
She could make new allies among the female characters who might be more inclined to help her now that she's a girl. For example, some of the female demigods who previously didn't interact much with Percy could now become her friends and allies.
