How can the concept of Izuku having a black fire quirk be developed in a fanfiction?

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.

One common plot element is Izuku struggling to control his dual - natured quirk at first. Since fire and ice are opposite elements, it's a challenge for him to balance them. Another is that he might face discrimination or suspicion from others who are afraid of his powerful quirk. Also, there could be a lot of training montages as he tries to master using both elements effectively.

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.

Well, a great plot could be Izuku's journey to master his fire quirk. He might seek out a retired hero with a fire - related quirk to train him. Along the way, he discovers that his fire quirk has a unique property, like it can burn through certain types of energy shields that most other quirks can't. This makes him a target for villains who want to study his quirk, and he has to fight to protect himself and his secret.

He could start by training to absorb more types of energy. For example, if he can currently only absorb physical energy like kinetic or thermal, he could learn to absorb electromagnetic energy too. This would open up new possibilities for his quirk usage. Another way is to increase the efficiency of his absorption. Maybe he can work on reducing the time it takes to absorb energy or increase the amount he can hold at once.
