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.
Deadpool is a wisecracking, anti-hero who has a messed-up past and gets into all kinds of crazy adventures while trying to deal with his own immortality and a penchant for mayhem.
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 really creative Deadpool fanfic I've read is the one where Deadpool time - travels. He goes back to different eras in the Marvel universe and causes all kinds of chaos. His interactions with the heroes and villains of those times are hilarious. Another one has Deadpool teaming up with a bunch of street - level heroes in a heist - like adventure. It's really fun to see how his unpredictable nature plays out in that situation.
Well, one key point is the battle between the two Deadpools. They likely have different motives or versions of themselves that lead to the fight. Maybe one is from an alternate universe.
Deadpool became Deadpool through a series of complex and sometimes convoluted events in the comics. He was originally a mercenary named Wade Wilson, who underwent experimental treatments that gave him his unique powers and personality.
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.
