First, give them a backstory. It could be something tragic like being bullied in school because of their quirk and then feeling abandoned by the hero system. This would fuel their anti - hero/villain mentality. For example, if their quirk was something that made them look different, they might have been shunned by society and heroes alike.
Another concept could be an OC anti - villain with a unique quirk that is often misunderstood. Their actions seem villainous on the surface, like stealing resources from big corporations. But in reality, they are redistributing those resources to the poor or underprivileged areas that the heroes and the government have overlooked. So, they are kind of like a Robin Hood - type anti - villain in the My Hero Academia universe.
A lot of anti - hero OCs have a sense of justice that is different from the mainstream heroes. They might not care about fame or public approval like the heroes do. Instead, they focus on what they think is right, which could involve breaking some laws or going against the hero establishment. Their appearance might also be more edgy or different from the clean - cut hero look. They could have a more 'street - smart' attitude rather than the polished hero demeanor.
To create a compelling villain in My Hero Academia OC fanfiction, first, give them a unique quirk. It should be powerful yet have some limitations. For example, a quirk that can control time but only for a few seconds at a time. Second, develop their backstory. Maybe they were once a hero-hopeful but were betrayed by the hero society. This would give them a reason to turn to villainy. Finally, give them a distinct personality. They could be charming yet extremely cruel, like the Joker from Batman.
First, give your OC a unique quirk that has both strengths and flaws. For example, a quirk that can control fire but has a time limit. Then, develop a backstory that explains why they become an anti - hero. Maybe they've been wronged by society or have a different view of heroism. Also, think about their relationships with other characters in the My Hero Academia world. Do they have friends among the villains or heroes? This can add depth to their character.
One popular archetype is the power - hungry villain. They crave more and more power, like All For One in the original series. Another is the vengeful villain. They have a grudge against someone or the whole hero society and will stop at nothing to get their revenge. There's also the mad scientist type. They conduct unethical experiments, often creating dangerous things in the pursuit of knowledge or power.
To create a compelling dark OC in My Hero Academia fanfiction, start with a strong motivation. It could be envy towards the heroes' popularity or a desire for power at any cost. Their quirk should be something that can cause chaos, like a mind - control quirk but with limitations such as it only works on those with weak wills. Appearance - wise, they could have a scar or some disfigurement that adds to their intimidating factor. And don't forget to give them a name that suits their dark persona.
There's also 'Anti - Hero Among Heroes'. In this fanfiction, the OC anti - hero challenges the traditional hero - villain dichotomy in the My Hero Academia universe. The story delves deep into how society views such a character and how the OC navigates through a world that doesn't quite understand them. It's full of action - packed scenes and thought - provoking moments.
A popular trope for OC anti - heroes in My Hero Academia fanfiction is the 'Secret Identity'. They might have a normal - looking civilian identity and then transform into their anti - hero persona when the situation calls for it. This adds an element of mystery. The 'Powerful but Unstable' trope is also common. Their quirk could be extremely powerful but difficult to control, which sometimes makes them a danger to themselves and others. This can lead to interesting storylines where they have to learn to master their power while also dealing with the world's perception of them.
One possible story could be that Uraraka turns villain due to being corrupted by power. Maybe she starts to use her quirk for self - gain, like stealing valuable items and floating them away. She could form an alliance with other villains, believing that the hero society has failed her.
