In 'deku meets future deku fanfiction', perhaps the future Deku warns the present one about upcoming threats. He could tell him about villains he'll face in the future and how to defeat them. This would give the present Deku an edge in his battles and also in his growth as a hero.
In the manga, Deku experiences various ups and downs. He not only becomes stronger physically but also matures emotionally as he takes on greater responsibilities. There are also many unexpected plot twists that shape his journey.
It could lead to a completely different character dynamic and story arc. Maybe she'd face different challenges and have a unique perspective on being a hero.
One possible plot could be that Villain Deku is on a mission to undermine the hero society and crosses paths with Hero Deku. They engage in a fierce battle where Villain Deku taunts Hero Deku about his ideals. In the end, Hero Deku manages to get through to a small part of Villain Deku's conscience, leaving him with some doubts about his villainous path.
Another plot might involve the older Deku being from an alternate timeline. He shows the younger Deku different ways he could have developed his skills and relationships, which makes the younger Deku reevaluate his own path as a hero.
One great Deku fanfic is 'Deku: The Unseen Hero'. It really delves into Deku's inner thoughts and his journey in a unique way. The character development in it is top - notch, making Deku seem even more relatable than in the original work.
In an 'evil deku fanfic', the story may focus on Deku's journey into darkness. He might start to see the flaws in the hero system and decide to take matters into his own hands in a bad way. He could form alliances with villains or create his own brand of 'justice' that is really just a cover for his evil deeds. It could also explore how the other characters react to this new, evil Deku and whether they try to save him or stop him.
There are Deku fanfics that are all about his growth as a hero. In these, he could be learning from other pro - heroes, not just All Might. He might get involved in international hero missions. Some fanfics also like to play with the idea of Deku's love life. It could be a romantic relationship with another character from the series, or even an original character created by the fanfic author.
I'm not entirely sure specifically as it could vary greatly. Fanfiction often takes a character, in this case Deku, and creates a fictional story around the idea of pregnancy. It might explore different scenarios like how he and other characters deal with it, or it could be a very creative and out - of - the - box take on the concept within the context of the original story's universe.
