Our hero Sonic Doom’s superpower is the ability to be ridiculously loud in everything he does: he stomps around his apartment, bangs kitchen cabinet doors, smashes things into his metal sink, blasts music and cranks the TV up so loud nobody can stand it, yells and screams at people on the phone, punches doors, snores really loudly and bangs around on his bed all night due to restless leg syndrome, etc. And he uses this power for good by moving in next to super villains and banging around and blasting music and the TV and generally creating an unbelievable racket, and then following the super villains around in a boom box Jeep blasting annoying music wherever they go until the super villains turn themselves in to the police just to get away from all the noise.
(I have a neighbor like this who seemingly has a superhuman capacity for making noise. So he made me think of how his powers might be used for good.)
