Well, Todoroki is frequently paired with Izuku in such fanfictions. Given Todoroki's own powerful quirk and his journey of self - discovery, he and Izuku with his voice quirk can have some great interactions. They might train together, and Izuku could use his voice quirk to help Todoroki better control his own quirk's temperature aspects. Momo is another one. As a smart and resourceful character, she could help Izuku understand the scientific aspects of his voice quirk, like how sound waves work and how to optimize his quirk usage. And of course, Iida. Iida's strict sense of justice and leadership could pair well with Izuku. He might encourage Izuku to use his voice quirk for the greater good and help him come up with strategies to use it in hero work.
One interesting plotline could be Izuku using his voice quirk to communicate with animals. Since many animals respond to different frequencies and tones, his voice quirk might allow him to understand and direct them. For example, he could use it to get a flock of birds to create distractions during a villain attack. Another plotline might involve Izuku using his voice quirk to soothe people in distress. His voice could have a calming effect, which would be useful in rescue situations or when dealing with panicked civilians. And a third plotline could be Izuku having to train his voice quirk in secret because it's considered too dangerous or unpredictable, and he has to find unique ways to control and develop it without getting caught by the wrong people.
Some characters might be immediately terrified. They could avoid Izuku or even try to drive him away. For example, classmates who don't understand his quirk might spread rumors about him.
In 'The Healer of UA', Izuku's healing quirk is more complex. It requires him to concentrate and visualize the injury being healed. He can also transfer some of his own stamina to the injured to speed up the process. This makes his quirk not only about physical healing but also about his own sacrifice and determination.
One great 'Fem Izuku has a Quirk' fanfiction is 'Powerful Ascent'. In this story, Izuku's quirk is a unique combination of telekinesis and energy manipulation. The author does an amazing job of exploring how a female Izuku would face the challenges in the hero academy with such a powerful quirk. It also delves into her relationships with other characters like Bakugo and Todoroki in a really interesting way.
In some fanfictions, Izuku might discover he has his father's quirk during a moment of extreme stress. For example, when facing a powerful villain that he couldn't defeat with his own quirk, suddenly a new power, which turns out to be his father's quirk, emerges.
One unique aspect is that Izuku can often treat real - life situations like game scenarios. For example, he might view a villain fight as a boss battle, which gives a fresh perspective on the action. Another aspect is the leveling system that often comes with the gamer quirk. He can gain experience points and level up, which is different from the normal quirk development in the original series.
Well, one possibility could be that Izuku uses his dragon quirk to quickly rise in the hero rankings. His dragon powers might include things like breathing fire or having super strength. He could face challenges from villains who are specifically targeting his unique quirk.
Izuku could develop by learning to accept his vampire quirk. At first, he might be scared or ashamed of it, but as he realizes the potential it has for good, he grows more confident. For example, when he saves someone using his vampire - enhanced abilities.
His relationships with his friends would likely become more complex. If he starts using his time quirk to change things, his friends might not remember the original timeline, but Izuku would. This could create a sense of isolation for him as he holds memories that no one else does.
