Perhaps in a post - apocalyptic scenario in a combined Dragon Ball and Fairy Tail universe, Goku and Ultear are among the few survivors. They meet while searching for resources. Goku is attracted to Ultear's intelligence and determination, and Ultear is intrigued by Goku's incredible power. They form an alliance to rebuild society. They share their respective knowledge, like Goku sharing his Saiyan heritage and Ultear her knowledge of magic. Their relationship is one of hope and cooperation for a better future.
A plot could involve Ultear using her magic to accidentally transport Goku to a parallel dimension where she resides. Goku, being his curious self, is eager to explore this new place. Ultear is initially cautious but soon realizes Goku's pure intentions. They start training together, with Ultear learning about ki energy from Goku and Goku learning about her time - based magic. Their relationship could grow into a strong bond that is more about companionship and mutual growth rather than any improper content.
One possible plot could be that Goku, during his travels across different universes, somehow ends up in Ultear's world. At first, they are distrustful of each other. But as they face common enemies together, they gradually develop a mutual respect. Eventually, this could lead to a deep friendship that some might misinterpret as a romantic relationship, without any inappropriate 'lemon' aspects. They could team up to save Ultear's world from a powerful, dark force, with Goku teaching Ultear some of his unique fighting techniques along the way.
One possible plot could be that Goku and Kale are forced to team up during a universal threat. They start off not getting along due to Kale's shyness and Goku's carefree nature. But as they face challenges together, they gradually learn to understand and respect each other. For example, Goku could teach Kale some new fighting techniques, and Kale could show Goku a different way of approaching battles with her unique Saiyan powers.
Maybe in the fanfiction, Goku accidentally uses a new technique that causes him and Android 18 to be mentally linked. Through this link, they start to understand each other on a deeper level. They then find themselves drawn to each other's strength and determination. But they have to hide their growing relationship from their friends and family who might not understand.
Well, it could be about Goku and Caulifla training together in a really unique way. Maybe they discover a new form while training in a strange place. And this could lead to them having to fight side by side against a powerful enemy that neither of them could face alone.
For Goku, his character can be developed by showing his adaptability to Ultear's world. He could learn about different types of magic and use his Saiyan ability to incorporate some aspects of it into his fighting style. For Ultear, she could grow in terms of her understanding of different power sources. Goku's simple yet strong sense of justice could inspire her to be more straightforward in her actions and less manipulative if she has such tendencies in her original character.
One possible plot could be that Lemon, with her unique abilities, somehow gets transported to the Dragon Ball universe. Goku, being the curious and friendly Saiyan he is, decides to help her find her way back. Along the way, they face some common enemies. Goku teaches Lemon about ki and fighting techniques, and Lemon shows Goku some of her own skills from her world. This could lead to an epic team - up against a powerful villain who threatens both their worlds.
One possible plot could be that Goku accidentally travels to a world where Lemon is a powerful being. They start as rivals but gradually learn from each other's strengths. Goku could teach Lemon about his fighting techniques and his Saiyan heritage, while Lemon could show Goku some unique powers or skills from their world. Then they team up to face a common enemy that threatens both of their worlds.
Maybe in a post - Cell Games world, Android 18 has become more integrated into the Z - Fighters' group. Goku, always open - minded, starts to notice her more as a person rather than an android. They go on a mission together where they are trapped in a dangerous situation. In the heat of the moment, they share a kiss as a sign of their new - found connection and a hope for survival.
Well, perhaps in the fanfiction, Natsu and Ultear get married in a grand ceremony attended by all their friends from the guild. After marriage, they decide to go on adventures together. Ultear could use her time - magic to help Natsu in battles, like rewinding time a bit to give him an edge. They also start a family, with Natsu teaching their kids about the importance of friendship and Ultear teaching them magic.
Perhaps in this fanfiction, a magical spell goes wrong and creates a baby that has a connection to both Natsu and Ultear. They then have to deal with the consequences. Natsu might try to use his fire magic to keep the baby warm in a rather clumsy way at first. Ultear, on the other hand, uses her time - related magic to create things for the baby like a cozy crib or toys. They face challenges like getting the baby to sleep through the night and protecting it from any villains who might want to use the baby for their own evil purposes.
One idea could be that Ultear and Gray are on a mission together in a mysterious land filled with magical creatures. Along the way, they discover a hidden lemon grove that has some special magical properties related to their powers.
