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.
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 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.
One possible plot twist could be that when they time travel, they accidentally change a key event in the past that has a domino effect on their present. For example, they might prevent the formation of a guild that was crucial in their original timeline. Another could be that they find out they are related in some unexpected way through their time - traveling adventures. Maybe Ultear discovers she has a connection to Natsu's family that was lost in history. Or perhaps they time travel to a future where everything they know is in ruins, and they have to figure out how to prevent it in their present.
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.
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.
One good story could be 'A Magical Bond' where Natsu and Ultear go on an adventure together and their relationship develops in unexpected ways. It has great character interactions.
Another option could be Wattpad. There are many fanfiction writers on Wattpad who might have written stories about Natsu and Ultear. However, you may need to do a bit more searching as there is a large amount of content on the platform.
Perhaps a plot where Ultear uses her time - related magic to go back in time and meet a younger Natsu. She initially has an ulterior motive but ends up falling for him. Their relationship develops in a series of flashbacks and present - day interactions, with a lot of emotional and some mildly romantic undertones, but without crossing into inappropriate territory.
I'm not entirely sure as 'ultear lemon fanfic' could refer to a very specific piece of fan - created work. It might be a fanfic related to a character named Ultear, and perhaps the 'lemon' in the title could imply some sort of citrus - themed or fresh - themed aspect in the story. But without more context, it's hard to be more specific.
