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.
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.
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.
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.

In fanfiction, Izuku's pride quirk could make his relationships more complex.

For example, he might be so determined to prove his pride in his quirk that he doesn't listen to their advice.
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.

This not only helps him control his quirk better but also increases his overall combat capabilities.
Well, his original quirk is One For All which is more of a power - storing and transferring quirk. The black lightning quirk in fanfiction is likely more offensive - oriented. It can be used for direct attacks like shooting bolts of black lightning at enemies.
Well, initially, Izuku might be overwhelmed by his new cosmic quirk. But as he trains, he becomes more confident. For example, he could start by accidentally causing small cosmic disruptions and then learn to control them precisely.
