For a 'boku no hero academia oc vigilante fanfic', you could focus on an OC who is a vigilante because they believe the current hero system is too slow or bureaucratic. They could have a quirk that allows them to create portals, which they use to quickly get to crime scenes before the heroes arrive. Their story could involve them gradually building a reputation among the people in the city, both feared and respected by different groups.
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.
