Sonic Girl
Sonic Girl — superheroine featured in films and comics on Superheroines.net.
Sonic Girl is the office worker by day, super-powered defender by night. Her stories often start with a wrong-place-wrong-time encounter — a burglar in her apartment, a crooked ex-con who thinks he's caught her off-guard — and pivot the moment she decides to drop the alter-ego. She occasionally teams up with Superwoman when the situation calls for it.
