In fanfiction, Izuku often has unique ways to cultivate his quirk. One common scenario is that he focuses on intense physical training. Since his body was initially not as strong as it could be to handle his powerful quirk, he might do a lot of strength - building exercises like weightlifting and running. This not only helps him control his quirk better but also increases his overall combat capabilities.
Well, Deku does lose his quirk. However, this event leads to new developments and challenges for him. It's a crucial plot twist that adds depth to the story.
It might also change his relationships with other characters. His friends could be both amazed and a bit envious. And his enemies would start to see him as an even greater threat. For example, Bakugo might feel more pressured to compete with Izuku who now has an additional powerful quirk.
His relationship with his mother could become more complex. She might be worried about his new nature and try to protect him more. With his friends, like Bakugo, they might initially be scared or distrustful when they find out about his quirk.
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.
His relationships with others might change. His friends could view him in a new light, either with admiration or envy. Enemies might start to target him more, seeing him as a greater threat now that his quirk is unlocked.
In many fanfictions, Izuku might unlock his quirk through intense emotional experiences. For example, a moment of extreme anger or determination could trigger it. Maybe seeing his friends in great danger and feeling a strong need to protect them could be the catalyst.
In some fanfiction, Izuku also experiments with different environments to cultivate his quirk. If his quirk is related to strength, he might try training in places with different gravitational forces. This forces his body and quirk to adapt, and in the process, he can discover new ways to use and develop his quirk.
