Kakashi's experience and intelligence would also be great assets. He could analyze the quirks of his opponents and come up with strategies to defeat them. He could also teach the heroes in MHA new ways of thinking about combat and teamwork, based on his ninja training.
Uraraka's zero - gravity Quirk could work well with a Stand like The World. She could make objects weightless and then use The World's time - stop to position them in the perfect place for a powerful attack. For example, making a large boulder weightless, stopping time, and then moving it right above an enemy before time starts again.
One idea could be that Kakashi is somehow transported to the My Hero Academia world. He could become a teacher at UA, using his ninja skills and wisdom to train the students in new and unique ways. His Sharingan would be a very interesting power in the MHA universe.
Well, if we consider a character like Todoroki having Ghost Rider powers on top of his own. His ice and fire powers could interact with the hellfire of Ghost Rider. Maybe his ice could be used to temporarily cool down the intense flames of Ghost Rider for strategic purposes, like creating a smokescreen or freezing enemies in place before hitting them with the full force of the Ghost Rider's vengeance. And his fire side could merge with the Ghost Rider fire to create an even more powerful and unique attack.
The quirks in My Hero Academia are often very physical and unique to each individual. In a crossover, Uraraka's zero - gravity quirk could be used in space battles in the Star Wars universe. She could disable enemy ships by making them weightless. On the other hand, the Force abilities in Star Wars, like mind control and precognition, could give the My Hero Academia characters an edge in combat. For example, Todoroki could use his ice quirk in combination with a Jedi's precognitive ability to anticipate his opponents' moves and freeze them in place before they can act.
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.
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.
Well, if a character was half Kree and half human in My Hero Academia fanfiction, their abilities could be a really cool mix. The Kree are known for their advanced technology and physical strength in the Marvel universe. So this character might have enhanced strength like a hero in My Hero Academia who has a strength - based quirk, but it could be on a different level. Maybe they could also have some kind of energy - based power from the Kree side that they could use in combat, like shooting out blasts of energy while also having the ability to use their human - like intelligence to strategize in battles.
Luffy's rubber powers could be seen as a very unique quirk. He could use his stretching abilities for both offense and defense. For example, he could stretch his arms to grab villains from a distance or use his body to shield others from attacks.
He would likely have enhanced strength. The symbiote could augment his natural physical strength, allowing him to lift heavier objects and deliver more powerful punches. His speed would also increase. With the symbiote, Izuku could move at a much faster pace, making it easier for him to dodge attacks and close in on opponents quickly.
Well, if we consider Denji's chainsaw powers and a hero's Quirk like Todoroki's ice and fire. They could create some really cool combos. Denji could use his chainsaws to cut through obstacles while Todoroki freezes or burns enemies in their path. The physical strength of Denji combined with the elemental control of Todoroki would make for a formidable team.
