One common character paired with 'female Luffy' is Zoro. In some fanfictions, their relationship could be more of a romantic nature. Zoro might be the first one to notice the changes in Luffy when she reveals her female side, and then they start to develop a deeper connection. Their dynamic would be different from the original, with more of a romantic tension added to their usual banter.
Sanji is also often paired with 'female Luffy'. Given Sanji's love for women, his reaction to a female Luffy would be quite extreme. He might go overboard in trying to protect her and court her. The fanfiction could explore how Luffy deals with Sanji's over - the - top behavior while still maintaining her role as the captain. It would be a comical and interesting relationship to write about.
Nami could also be a common character. She might help Luffy manage the financial aspects of his admiral duties, as well as use her navigation skills to assist in any navy - related voyages. And of course, she'd be there to keep Luffy in check when he gets too carried away.
Some fanfictions also pair Luffy with Hancock. Given Hancock's infatuation with Luffy in the original series, it's not a stretch to develop a full - blown love story. Her powerful status as a pirate empress and Luffy's carefree nature can create an interesting dynamic, with Hancock trying to win Luffy's heart while he is mostly oblivious to her romantic intentions.
Zoro is another popular character. He and Luffy have a strong bond, and in Gear 5 fanfiction, they might fight together in a new and more coordinated way. Zoro could be using his swordsmanship to complement Luffy's wild and unpredictable Gear 5 attacks, creating a powerful combination against their enemies.
Optimus Prime is sometimes paired with baby Soundwave. Their interactions can be really interesting as they come from opposite sides. Optimus might take on a mentor - like role towards baby Soundwave, teaching him about things like morality and the value of life.
Stan can also be paired with Kenny. Stan's more moral - centered character can contrast with Kenny's somewhat nihilistic view of his own mortality. In a crossover with a post - apocalyptic world, Stan might be trying to find a way to save humanity while Kenny is just along for the ride, but still manages to survive in the most unexpected ways.
Cheelai and Lemo from the Broly movie might also be paired with the reincarnated Broly. They could act as his guides or friends in the new world he finds himself in, helping him navigate the complex politics and power dynamics of the Dragon Ball universe.
Naruto can also be paired with Sakura in these fanfictions. Since they are such close friends in the original, in a reincarnation scenario, their friendship could potentially turn into something more romantic. They could support each other in different ways than in their past lives.
Hermione is often paired with Harry. She might help him study and understand the animagus transformation better. Also, Ron could be there, providing his usual comical relief and loyalty. They could get into all sorts of adventures together with Harry as an animagus.
Indra and Asura are also characters that are frequently paired with Hagoromo in fanfiction. These pairings often explore the family dynamics more closely, such as Hagoromo teaching them new skills or them helping Hagoromo in some way that was not shown in the original series.
Sometimes Jungkook is paired with Taehyung. They could be partners in a fight against evil supernatural entities. Their bond might be strengthened through shared experiences and mutual understanding in the supernatural world. There are also fanfictions where they discover some unique connection between them, like a telepathic link.
