Another plot idea is that the ancestor's quirk is a shape - shifting ability. Midoriya struggles at first because it's so different from his original quirk. He accidentally transforms into various things at inopportune times. But as he practices, he learns to use it for stealth and surprise attacks, and it becomes a key part of his hero repertoire.
His relationship with All Might could change. All Might might be both proud and a bit worried. Proud that Midoriya has this new power from his ancestry, but worried about how it will affect Midoriya's growth and the way he uses his existing quirk. They would have more in - depth discussions about power management.
One possible aspect to consider in this fanfiction could be the unique challenges Midoriya might face. Since he's the only male with a quirk, he might be ostracized or overly idolized. For example, in a society where most males lack quirks, he could be a target for jealousy or envy from his male peers. At the same time, he might be seen as a symbol of hope for some, which could put a great deal of pressure on him.
His growth could also come from his interactions with others. He may learn from female characters who have more experience with quirks. Through these relationships, he could gain a better understanding of his own abilities and his place in the world. As he faces various challenges, he'll gradually become more self - assured and develop his quirk in ways that are unique to his situation.
It could be developed by having Izuku practice and gradually increase the duration of his time - freezing ability. For instance, at first, he can only freeze time for a split second, but with training, he can hold it for a few seconds, which makes a huge difference in combat.
A well - liked fanfiction is 'Midoriya's Dual Quirks'. As the title suggests, he gets not one but two quirks. This makes for an interesting read as he has to balance using both and figure out how they interact. There's also 'The Forbidden Quirk' where Midoriya gets a quirk that is considered dangerous or taboo in the My Hero Academia universe. It creates a lot of conflict as he tries to keep it a secret while also using it for good. And 'Quirk of the Ancients' where his new quirk has roots in an ancient, long - forgotten power source, leading to a journey of discovery about the history of quirks.
A great plot could involve Midoriya teaming up with other characters in a co - op mode enabled by his Gamer Quirk. They would have to strategize and combine their different quirks to progress through various challenges, like rescuing hostages from a villain - infested building. This would not only test their combat skills but also their teamwork abilities.
One idea for Izuku Midoriya's quirk in a Dark Souls - inspired fanfiction could be 'Soul Link'. This quirk would enable him to form a link with other people's souls. He could use this link to either heal them by sharing his own energy (similar to Estus Flasks in Dark Souls), or he could disrupt their soul's energy, causing them to be weakened or even stunned. It could also work as a way for him to sense the presence and intentions of others, as he would be attuned to their souls. This quirk would give him a unique advantage in battles and also in forming relationships with other characters in the fanfiction.
On the other hand, his Gamer Quirk can also bring him closer to some characters. If there are other characters who are also into gaming or understand the concept of leveling up, they might bond with Midoriya over it. For instance, he could form a closer friendship with a character who also has a quirk that has some game - like elements. They could exchange tips on how to better use their quirks.
Well, in a fanfiction where Midoriya gets a quirk, the power dynamics at U.A. High could be completely different. He might not be the underdog that he was in the original plot. His new quirk could lead to new friendships or rivalries. For instance, if his quirk is something extremely powerful, some students might be jealous, while others might look up to him more. Also, the story's focus on All Might's legacy might shift as Midoriya's new quirk may not be related to One For All.
