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.
If Spider Man had all the Infinity Stones, he would be extremely powerful. He could use the Time Stone to reverse bad events or prevent disasters. The Power Stone might enhance his physical strength to an unimaginable level, making him even more capable in combat against powerful foes. And with the Mind Stone, he could perhaps gain greater wisdom and understanding of his enemies' plans.
Well, he'd probably be super powerful. He could use the Infinity Stones' powers to defeat villains with ease. Maybe he could even use the Time Stone to go back and prevent some of the bad things that happened in his world. With the Power Stone, his physical attacks would be off the charts.
If Percy Jackson had the Infinity Gauntlet in fanfiction, it would completely change the power dynamics. He might use the Reality Stone to create illusions or change the nature of things around him. For example, he could turn the sea into a solid surface for his enemies to struggle on. And with the Power Stone, his physical strength would be off the charts, allowing him to take on even the mightiest of foes with ease.
In a fanfiction where Harry Potter has the Infinity Stones, his life would take a completely different turn. First of all, the Space Stone would enable him to teleport anywhere in the wizarding world or even beyond. This would make it impossible for his enemies to catch him. The Soul Stone, on the other hand, might have some deep connection with the wizard's soul. Maybe it could help him understand the true nature of magic and his own destiny better. He could use all these stones' powers in combination to bring about a new era of peace and magic in the wizarding world, but he would also have to face the great temptation and potential corruption that comes with such immense power.
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.

They engage in a fierce battle where Villain Deku taunts Hero Deku about his ideals.
