One interesting story could be where Izuku's portal quirk allows him to access different dimensions filled with unique heroes and villains. He might use this to learn new combat techniques.
Another great one is a fanfiction where Izuku's portal quirk causes him to interact with characters from different timelines. Through these interactions, he grows as a person. He sees different versions of himself and learns from their mistakes and successes. This makes him more confident and helps him better understand his own power.
The Gamer Quirk also changes Izuku's relationship with others. He can now offer unique insights based on his quirk. For instance, he might be able to analyze a villain's attack pattern like it was a boss fight in a game. His friends and allies can then use this information to their advantage. This makes him a valuable member of any team. At the same time, it also means that he might be seen as a bit of an oddball because his thinking is so different from the norm. But overall, it helps him form deeper connections with those who understand and appreciate his quirk.
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.
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.
Bakugo is often paired with Izuku. Their complex relationship from the original series can be further explored in fanfiction with Izuku's growth quirk. All Might is also a common character paired with Izuku. He could play a role in guiding Izuku to control and develop his growth quirk. Ochaco is another one. She might be involved in stories where Izuku's growth quirk affects his relationships, especially romantic ones.
Bakugo is often paired with Izuku. Their relationship is complex in the original series, and in fanfiction with Izuku's time quirk, it could add more depth. Bakugo might be jealous of Izuku's new power at first but then come to respect it as they face challenges together.
There are also fanfictions where Izuku's quirk has a hidden aspect. Maybe his connection to One For All unlocks memories or abilities from the previous users in a more profound way. For instance, he might be able to access the combat knowledge of the past users directly, almost like having an in - built combat instructor guiding his every move.
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.
