I'm watching Justice League Season 4 Episode 1: The Cat and the Canary, the bad guy at the front of that group about to attack Black Canary is Atomic Skull.
The image isn't the best but can anyone tell me who the rest of the bad guys are?
I'm aware they may just be made up background villains for this particular episode, but since there are so many DC characters to pick from, I'm guessing they're canon.
