If Deku had a quirk in fanfiction, it would likely impact his character development. He might have become more powerful quicker or taken on different enemies. The story could become much more action-packed or focus on different themes.
It could make for a really exciting and unique story. Deku's growth and challenges would be measured in a more structured way, adding a new layer of excitement to his journey.

Well, Naruto with all lantern rings would be a total game - changer in the fanfiction world. The lantern rings come with various emotional spectra - based powers. Naruto, being a character full of determination and a strong will, would be able to fully utilize the Green Lantern ring's capabilities. Also, the powers of the other rings, like the Blue Lantern's hope - amplifying abilities, could enhance his already existing positive traits. He might be able to use the rings to protect the ninja world from threats that were previously unbeatable.
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.
I recommend a novel to you-- In this oriental fantasy novel, other than humans and animals, there were also elves, including the protagonist, the nine-tailed fox who was born in the spiritual domain. I hope you like this fairy's recommendation. Muah ~π
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.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
