Next, consider the plot. You can base it on a conflict that arises from the two different characters' beliefs or goals. For example, if you cross Stain with a more traditional hero type, they might have a big argument about what it really means to be a hero. You also need to make sure you stay true to Stain's original character while also making the crossover work.
One popular type might be a Stain crossover with other well - known anime characters. For example, a crossover with All Might could explore an interesting dynamic where their opposing views on heroism clash. Another could be a Stain crossover with Deku, perhaps showing how Deku's ideology might be challenged or changed by interacting with Stain.
Fanfictions related to Stain from 'boku no hero academia' can vary greatly. Some might depict him as a more sympathetic character, trying to understand his motives for his extreme actions. Others could be more action - oriented, with Stain engaging in battles that we didn't see in the anime or manga. There's also the possibility of exploring his backstory further, like his early days and what led him to become the character we know.
One common theme is the conflict between their different ideologies. Stain has his extreme views on heroes, while Iida has a more traditional heroic view. This contrast often creates an interesting dynamic in the stories.
Well, it could be that Stain kidnaps Iida to use him as a bargaining chip against other heroes. He might think that by having Iida in his custody, he can make demands on the hero community, like asking for changes in how heroes operate or for certain heroes to be punished. Another possibility is that Stain wants to prove a point to Iida about the flaws in the hero system. He may hold Iida captive and show him examples of what he believes are the wrongdoings of heroes, trying to sway Iida's loyalty from the hero side to his own view of justice.
One good 'Stain Trains Izuku' fanfiction could be 'The Training of a Hero' where Stain imparts unique combat skills to Izuku. It shows how Izuku's determination combines with Stain's unorthodox training methods. Another might be 'Stain's Influence on Izuku' which delves into the psychological impact of Stain on Izuku's view of heroism.
One common theme is the exploration of Stain's sense of justice. Since he has a very distinct view on what makes a true hero, fanfictions often delve into this concept, comparing it with the more mainstream ideas of heroism in the 'boku no hero academia' universe.
The story could progress with Iida trying to escape on his own. He might use his intelligence and his quirk in unexpected ways to break free from Stain's clutches.
