Some fanfics might equalize the power levels for the sake of a more balanced story. They could give characters new power - up or limitations to fit within the combined universe. For example, a really powerful character like Gildarts from Fairy Tail might be weakened slightly when in the Black Clover world to make the battles more interesting.
Rarity would be more interested in how the power levels are presented visually. If there are any shiny or impressive displays of power, she would be all about it. Pinkie Pie would just turn it into a game, making up her own power levels for the Mane 6 and seeing how they stack up against the Dragon Ball characters. Applejack would think the power levels are a bit over - the - top but would respect the fact that it's part of the Dragon Ball world.
Yuno would be completely shattered. He has always seen Asta as his rival and friend. He would probably blame himself for not being strong enough to protect Asta. His grief might turn into a cold determination to change the world in Asta's memory. Noelle would be heartbroken. She has deep feelings for Asta, and his death would be a huge blow. She might become more withdrawn initially, but then find strength in wanting to carry on Asta's ideals.
I'm not entirely sure if it's a popular genre. Fanfiction can cover a vast range of themes, and while there may be some works with such themes, it might not be mainstream. The Black Clover fanfiction community has a lot of different types of stories, from adventure and friendship to power - up scenarios.
Black Clover tells the tale of Asta's journey to become the greatest mage. It's full of magic, friendships, and intense battles. Asta's perseverance and the complex web of relationships make it an engaging story.
Yes. The Black Clover light novel offers additional insights and background details that aren't present in the main series. It's a treat for fans who want to delve deeper into the world.
