In a crossover fanfiction, the combination of powers could be quite complex. Let's take the idea of Uraraka's Zero Gravity Quirk and the power of the Float - Float Fruit from One Piece. If Uraraka were to somehow gain the ability of the Float - Float Fruit, she could manipulate gravity in even more extreme ways. She could make objects or people not only float but also move them around in mid - air with greater precision. Similarly, if Zoro were to be introduced to the concept of Quirks, his three - sword style could be enhanced with a Quirk that gives his swords special properties, like the ability to cut through any substance, even intangible ones like some Quirk - based attacks.
Since Deku can now access different percentages of 'One For All' power, he could share some of that power with Black Panther in a temporary boost. In return, Black Panther could use his knowledge of Wakandan technology to create some sort of device that helps Deku better control his power. This way, their powers would be combined in a more strategic and long - term way.
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.
Genos' robotic enhancements and Kirishima's hardening quirk could create an interesting combination. Genos could provide Kirishima with some technological upgrades to his hardening ability, making him even more indestructible. On the other hand, Saitama's speed could be combined with Iida's engine quirk to create a super - fast movement ability that could outpace almost any villain.
Well, in a My Hero Academia Undertale crossover fanfiction, the characters' abilities could combine in really interesting ways. For example, Deku's One For All could potentially merge with Sans' ability to dodge attacks effortlessly. Deku might gain the power to not only have super strength but also be able to anticipate and avoid attacks like Sans. And Ochaco's zero - gravity power could interact with the gravity - manipulating powers in Undertale. Maybe she could use her power to counteract some of the strange gravitational effects in the Underground world.
Chat Noir's Cataclysm power, which can destroy anything it touches, could be really dangerous in the My Hero Academia world. If he were to use it on a building, it would be similar to how some villains with destruction - based Quirks operate. However, the heroes in My Hero Academia might be able to use their powers to contain or redirect the effects of Cataclysm. For example, someone like Cementoss could create barriers to stop the spread of the destruction.
There could be a fanfic where the Quirks in My Hero Academia are seen as a form of Haki in the One Piece world. The heroes and villains from My Hero Academia have to adapt to this new way of seeing their powers. This creates a whole new set of challenges and alliances. For example, All Might could be seen as a Yonko - level threat with his powerful Quirk, which is now considered a super - strong form of Haki.
Well, think about it. If fem Naruto has her ninja skills and enters the Boku no Hero Academia world, her speed and agility from being a ninja could enhance her in combat situations where quirks are involved. Maybe she could use her Rasengan in a way that mimics a really powerful quirk - based attack. And her chakra could also be used to boost or counter other characters' quirks.
In a more complex way, their powers could interact on a molecular level. For example, Superman's invulnerability might be enhanced by Invincible's unique cellular structure, or vice versa. They could also share their knowledge of different fighting techniques based on their powers. Since Superman has been a hero for a long time, he could teach Invincible some new ways to use his powers effectively in combat, while Invincible could show Superman some new, more brutal (but effective) ways of taking down opponents.
His powers would be seen as extremely unique. Naruto's chakra - based abilities are very different from quirks. People in MHA would likely be both amazed and a bit intimidated. His ability to create hundreds of clones would seem like a super powerful quirk on its own.
Inuyasha's demon blood could interact with Naruto's Nine - Tails chakra. Since both are sources of great power, they might be able to create a unique power - up. Inuyasha could use the Nine - Tails' chakra to boost his speed and strength even further, while Naruto could learn from Inuyasha how to better control his inner 'demon' side. Their combined power could be used to break through powerful barriers or defeat extremely strong foes.
