Overall, the 'Boku no Hero Academia Vigilante' manga is great. It expands the universe of the original series and offers new perspectives. The art style is also top-notch.
One idea could be to create an OC vigilante who has a unique quirk that's not very flashy but extremely useful in stealth situations, like the ability to blend into shadows completely. This would add an interesting dynamic as they could move around unnoticed by villains and even some heroes. Another idea is to have the OC vigilante be from a family with a bad reputation in the hero world, so they have to fight against the stigma while trying to do good.
First, focus on their backstory. Why did they become a vigilante? Was it a personal tragedy, like losing a loved one to a villain's attack? Then, think about their quirk and how it shapes their methods. For example, if they have a fire - based quirk, they might be more brash and direct in their approach. Also, consider their relationships with other characters. Do they have a mentor who is also a vigilante? Or are they constantly at odds with the official heroes?
Well, in a 'Boku no Hero Academia' fanfic with 'breakdown' in the title, it could be about the breakdown of society as we know it in the BNHA universe. For example, if the hero system fails, how would that impact the different characters? Or perhaps it's about a specific quirk breaking down, like if a quirk starts to malfunction and cause problems for the user. This could lead to interesting storylines where the character has to deal with not only the physical problems but also the social implications.
In fanfics about Shigaraki from Boku no Hero Academia, he is often depicted with more complex backstories. Some fanfics explore his childhood traumas in greater detail, which gives readers a deeper understanding of his motives. For example, they might expand on how his family's neglect led to his current state of mind.
Fanfictions related to Stain from 'boku no hero academia' can vary greatly. Some might depict him as a more sympathetic character, trying to understand his motives for his extreme actions. Others could be more action - oriented, with Stain engaging in battles that we didn't see in the anime or manga. There's also the possibility of exploring his backstory further, like his early days and what led him to become the character we know.
Venom in Boku no Hero Academia fanfiction can add a really interesting and unique element. It could potentially give a character new powers or a different personality. For example, if a hero were to bond with Venom, they might gain enhanced strength and speed, similar to how Venom affects its hosts in the original Venom comics. It also might create an internal struggle within the character as they deal with Venom's more aggressive tendencies.
