There might be some extremely niche and perhaps not - very - well - known fanfiction with that idea, but it's not a common or mainstream concept. Usually, fanfiction crossovers are more likely to occur between universes that have some similarities in themes or aesthetics. Since 'Fairy Tail' and 'Dragon Ball' are so different in many ways, it would be a very creative and perhaps difficult concept to pull off in a believable way in a fanfiction.
I haven't come across such a fanfiction specifically. It seems like a very strange and unlikely crossover considering they are from different fictional universes. Erza Scarlet is from 'Fairy Tail' and Goku is from 'Dragon Ball'. The two universes have very different rules, powers, and storylines, so this would be a really out - there concept for a fanfiction.
Well, in such a fanfiction, the initial encounter between Erza and Goku would have to be crafted carefully. Maybe they meet during a multiverse - spanning adventure where different fictional worlds collide. As for the pregnancy, it would be a major plot point. Erza, being a strong - willed character from 'Fairy Tail', would have to face the physical and emotional challenges of carrying a baby that is part - Saiyan. The fanfiction could delve into how the baby's growth affects Erza's body and powers. There could be a lot of speculation about what the baby would look like and what kind of abilities it would inherit. And the relationships between the two main characters would also be a central focus. How would Goku support Erza? How would their friends react to this unexpected union? All these elements would make for a very unique and complex fanfiction.
One idea could be exploring how Erza balances her pregnancy with her duties as a strong mage. Maybe she has to take a break from dangerous missions and feels a bit restless. Another could be the reactions of her friends in Fairy Tail. They might be overly protective or excited for her.
It could be a story where Naruto grows up in the Fairy Tail world instead of the Hidden Leaf. Since Erza is known for her strict but caring nature, she would probably train Naruto really hard. Naruto might have a different set of values influenced by the Fairy Tail guild. He could also make some new friends among the Fairy Tail members and together they could face powerful enemies. His ninja way might get a new interpretation in the context of the Fairy Tail universe.
There are some new powers and skills she acquires. Also, her character development takes interesting turns.
Sure. A lot of fanfic writers prefer to stay away from adult - themed content. They might write about how Erza Scarlet and Erza Knightwalker could team up against common enemies. Maybe they'd write about how they learn from each other's fighting styles or how they come to understand each other's pasts better. So, it's very possible to find non - 'lemon' fanfics about them.
She would likely become more cautious. Erza is used to being fearless in battle, but with a baby on the way, she would start to think twice before jumping into dangerous situations.
In this fanfic, Erza might also help Naruto in terms of his emotional growth. Naruto has always carried the burden of being an outcast in the village initially. Erza, having faced her own challenges in Fairy Tail, could offer him advice and support. She could teach him the importance of loyalty to friends and comrades, just as she values her guildmates. This could lead to Naruto becoming an even more well - rounded character.
There are many fanfics about Erza Scarlet. Some focus on her adventures, her relationships with other characters in a platonic way, like her strong friendship with her guild mates in Fairy Tail. You can find these on various fanfic websites.
It could be about how they meet in a crossover universe. Maybe Goku accidentally travels to Erza's world or vice versa, and they fall in love over time and get married. Their different powers and personalities would make for an interesting dynamic in the story.
One plot idea could be them preparing for the baby's arrival. They might be seen shopping for baby clothes and nursery items. Another could be how they deal with the reactions of their friends in the guild. For example, some might be overly excited while others are more reserved.
