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.
The transformation aspect is really cool. When Izuku activates his dragon quirk, he might transform partially or fully into a dragon - like form. This can lead to interesting battles where he uses his new dragon - like body and abilities in creative ways. It also allows for exploration of his identity as he is no longer just 'Izuku', but a being with dragon powers.
A sense of isolation can be a theme too. Having a unique dragon quirk might make Izuku feel different from others at first. He could be ostracized or misunderstood by some of his peers. But then as the story progresses, he finds ways to connect with others and use his quirk for the greater good, turning that initial isolation into a strength.
It could be other villains who are jealous of Izuku's powerful dragon quirk. They might see his quirk as a threat to their own plans for domination or chaos.
One great 'izuku dragon quirk fanfiction' is 'Dragon's Ascent'. It shows Izuku with a dragon quirk evolving and facing various challenges in the hero world. Another is 'The Dragon - Hearted Izuku' which focuses on how his dragon quirk affects his relationships with classmates.
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.
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 Bakugo might change. Bakugo, who used to look down on Izuku, might now be a bit jealous or even more competitive as Izuku's Dragon Slayer quirk is very powerful. With his friends like Uraraka, she could be in awe of his new quirk and support him more actively in battles. Izuku might also attract the attention of some of the more powerful heroes in training, who want to team up with him because of his unique ability.
One idea could be Izuku struggling to control his dragon quirk at first. For example, he might accidentally breathe fire during a normal school day, causing chaos. Another plot could involve him discovering unique abilities of his dragon quirk, like flying at high speeds or having super - strong scales for defense. Maybe he has to face a villain who has a quirk that is specifically designed to counter dragon - like powers, which would make for an intense battle.
He might become more confident. Having a powerful dragon quirk could make Izuku realize his own strength, and he'd carry himself with more assurance. For example, he wouldn't be as shy when speaking up in class or to other heroes.
