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, 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.
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.
Killua has a very stealthy side to him as well. In a My Hero Academia fanfiction, this could be manifested as a quirk that allows him to become invisible or at least very difficult to detect. He could use this in combination with his speed to surprise enemies. It would also be interesting to see how he would interact with other characters like Deku and Bakugo, perhaps teaching them some of his combat techniques.
In a My Hero Academia fanfiction with Sasuke, his abilities would have a significant impact. The Sharingan's genjutsu aspect could be a new and terrifying concept in the MHA universe. Genjutsu can manipulate the minds of opponents, and in a world where mental manipulation isn't a common quirk, it could be a game - changer. His chakra control and ability to perform ninjutsu like the Chidori would also make him a formidable force. He could potentially team up with some of the MHA heroes and use his unique skills to take on powerful villains.
Well, Logan's powers would likely be considered extremely powerful in the My Hero Academia universe. His healing factor would give him an edge in battles as he could recover from almost any injury quickly. The adamantium claws would be a formidable weapon. However, he might face some challenges as his powers are more 'brutal' compared to the typical flashy quirks in MHA. He could be seen as a bit of an outsider in the hero community at first.
Saitama's overpowered nature would completely disrupt the power balance in the MHA universe. His simple yet extreme strength and speed would make him an outlier. For example, in MHA, most heroes have to strategize and work in teams against villains. But Saitama could just one - punch most threats away. This would change the way villains operate as well, perhaps making them more desperate or more likely to target Saitama directly. It could also lead to interesting scenarios where heroes might be both in awe and a bit intimidated by his presence.
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.
Well, Goku's powers are extremely overpowered compared to most in the MHA world. His super strength, speed, and energy blasts would be like nothing seen before. His Saiyan ability to constantly increase in power would make him a top - tier hero. For example, his Kamehameha wave could be like an ultimate move, but he'd have to tone it down to not cause too much destruction in the MHA cities.
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.
Batman in the My Hero Academia world would likely be a bit of an outsider at first. His dark and brooding nature might contrast with the more colorful and often optimistic characters in MHA. However, his intelligence would be highly respected. He could use his detective skills to help solve some of the mysteries that pop up in the MHA world, like the origin of certain quirks or the identity of villains who are hiding in plain sight. And his martial arts expertise would make him a formidable opponent in battles against villains.
