Curate, connect, and discover
This is an emitter type quirk that can turn off other people’s quirks. It works by the user having a radius around them that can turn the quirks off. With counselling or training they can change the size of the radius to make it bigger or smaller but be warned if it gets too big it can put a strain on the body. Even more training could result in them being able to single out certain people that don’t need their quirk turned off but much like before too many people with working quirks can strain the users concentration and physical state.
As a hero, I believe they would act as an underground hero much lick Eraser head but they can still hep out with larger style attacks with just turning the main threat off.
As a villain, they would be a descent threat and probably be being recruited by the League. They could force a hero into fighting group of quirked people while they’re left quirkless for the time being
It allows the user to have similar abilities to a siren. If they makes eye contact with anyone, the victim will feel an overwhelming desirer to obey the user. The user can only control one person at a time and the control will be broken once eye contact is broken or the task is complete.
Because no one can make eye contact with her she wears special glasses that block all chances of someone falling for her quirk. The reason for the quirk being related to a siren is because of her incredible beauty.
Strengths - The task has an almost 100% chance of being completed - also the user will have a natural attractiveness about them which allows the victim to be drawn to the user.
Negatives - The quirk never turns off, so any eye contact has to come with a task.
Support - A specially designed set of glasses/goggles which a one way style material to stop unnecessary victims getting controlled.
