Asta is still alive in the manga. The story keeps evolving with him at the center of the action. There have been many difficult situations, but he manages to overcome them without dying.
Asta and Yuno are childhood friends in a magical world. They both strive to become powerful wizards and fulfill their dreams. Their paths are filled with challenges and adventures.
For the Naruto fandom, bashing fanfiction could potentially turn some fans away from the overall fanfiction community if they feel that their beloved character is being unfairly targeted. In the case of Rias and Issei's fandoms from High School DxD, it could create a stir as well. Some fans might engage in debates with the writers of the bashing fanfiction, trying to defend the characters. This can lead to both positive and negative interactions within the fandoms. On one hand, it can spark discussions about the characters' qualities, but on the other, it can also lead to a hostile environment if not handled properly.
The impact on the fandoms is multi - faceted. In the case of the Harry Potter fandom, it can introduce new storylines and character developments that were not possible within the original series. Fans get to see how Harry would react in a completely different universe filled with superheroes. For the Avengers fandom, it adds a touch of the magical and the complex backstories of the Harry Potter world. This can attract new fans to both fandoms. It also encourages creativity as fans try to blend the different powers, cultures, and ethics of the two universes in their own works.
A common theme is Asta's growth. In these fanfics, he often starts as a novice in the game world and gradually becomes stronger. For example, he might learn new skills or unlock hidden abilities.
