-Black Canary single-handedly beats the menace-de-jour without the slightest problem
Given that the menace-de-jour doesn't actually have any combat training (unless I missed that part of violin classes or engineering school that teaches you to fight people), any competent super hero should be able to beat this guy with one punch.
OK, there's a little bit of skill in dodging his sonic beam. But this should have been a quick fight.
