In a My Hero Academia fanfiction, Gohan could be seen as a hero from another dimension. His moral code, which is similar to the heroes in MHA, would make him a natural fit. He could also train the students in new ways of combat, using his martial arts skills combined with his Saiyan abilities.
Gohan could bring a whole new dynamic to the My Hero Academia universe. His ability to go Super Saiyan could be seen as a quirk in this world. However, he would also have to deal with the villains in MHA, which are different from the threats he faced in the Dragon Ball universe. His intelligence and strategic thinking would be assets in fighting against them.
Well, Kakashi could be a transfer student from a different hero academy. His Sharingan ability would be quite unique in the MHA world. He could use it to quickly analyze opponents' quirks and fighting styles, much like he did in Naruto. His combat experience and ninja skills would make him a formidable hero, and his laid - back attitude might contrast with some of the more intense MHA characters.
Gohan could fit in by being a transfer student. His Saiyan powers would be seen as a very unique 'quirk'. In the harem aspect, his kind heart would draw the attention of the female characters. For example, Mina would find his positive attitude infectious.
One way Shirou Emiya's abilities could fit is through his projection magic. In the MHA world, it could be seen as a form of quirk where he can project weapons. This would make him a unique combatant, similar to heroes like Snipe who use ranged weapons. He could use his projections to quickly adapt to different battle situations, for example, projecting a shield when facing a powerful ranged attack or a sword for close - quarter combat.
Saitama's overpowered strength would likely be a huge disruptor in the MHA world. His simple yet extreme power of being able to defeat any enemy with one punch would make him a top - tier hero instantly. Genos, with his advanced cybernetic enhancements, would also be quite formidable. He could potentially be part of the development of new support items or hero gear in the MHA universe, given his knowledge of technology. And his combat abilities would put him in the ranks of the stronger heroes there.
Tsuna's quirk, if we assume his Dying Will Flames are his quirk in the MHA universe, would likely be classified as an emitter type quirk. He could use his X - Burner attack as a long - range offensive move against villains. His hyper intuition could also be a part of his quirk, allowing him to predict his opponents' moves in battle. This would make him a valuable asset in hero teams, especially in complex battles where strategy is key.
Well, Goku's super strength and his ability to constantly power up could be a huge asset in the My Hero Academia fanfiction world. He could be like an otherworldly hero with his Saiyan powers. His Kamehameha wave would be an extremely powerful quirk - like ability. Maybe he could be a visiting hero from another dimension, coming to help out in the battles against the villains in the My Hero Academia universe.
Well, one way could be that Ichigo arrives in the My Hero Academia world through some sort of interdimensional portal. His powers, like his Soul Reaper abilities, would be seen as a very unique and powerful quirk. He might end up at UA, either as a student or a guest instructor. His strong sense of justice would align well with the values of the heroes in that world.
In fanfiction, Broly might be a villain who comes to the My Hero Academia world seeking a worthy opponent. His raw power would pose a huge threat to the heroes, and they'd have to figure out how to stop him without getting killed.
Sakura Haruno might enter the MHA universe through some sort of multiverse portal. Once there, her strong - willed and determined nature would make her a great hero - in - training. She could learn to use her physical strength, which she had developed in the Naruto world, in combination with a new MHA - style quirk. For example, she could have a quirk that enhances her strength even further when she focuses her chakra (or a similar energy concept in MHA). This would make her a formidable force against villains.
Well, Edward's alchemy could be a really unique power in the MHA world. His ability to transmute matter could be seen as a super - quirk. Maybe he could use it to create barriers or weapons during battles, like he did in his own world. He might also be able to use alchemy to heal injuries, which could be a great addition to the heroics in MHA.
