I'm working on a vigilante (his name will be Lockdown) that has the ability to cancel any special powers from a person he makes eye contact with, pretty much like Eraser Head from My Hero Academia.
The thing is, I'm not satisfied with only stating that he can cancel powers, so I'm trying to figure how this could "cientifictly" work. Since all powers at My Hero Academia are derived from Quirks, it's easier to explain.
Since Champions Lore has a lot of derivative powers, I'm trying to justify how Lockdown would cancel powers. Right now I'm inclined to state he can only cancel non-magic powers.
The best explanation I have so far is: upon eye contact, Lockdown sends spontaneous telepathic suggestions to the person's brain, forcing it to block the power's manifestation. The telepathic suggestions are continous, so if he blinks or lose sight of the person, the block ends.
Any suggestions and feedback are welcome. @bulgarex
if you know any similar CO hero or villain that can do this, please let me know!
