Pokemon one did the series dirty, you could get a random mouse or a thunder god. Ope Ope No Mi seems like the best answer, yeah I'm taking perfect surgery, lightning manipulation, detecting lights, and barriers
Also even if it's not yeah, I think it's more fun at night anyways. The Moon is 10x cooler AND I can stare at it without going blind. I think my ability would be sound control, being able to throw my voice anywhere and mimic the sounds of anything like a mocking bird. I could send large soundwaves out to attack/disrupt my opponents, and cause a sort of temporary delirium with sensory overload through the ears and filling my enemy's head with thoughts or ideas. I have to speak for any of this to work so my throat and mouth would be my assets that if destroyed I would have to replace like ACDC replacing his arm.
