In the DC Multiverse, there is an alternate earth known as Earth-3, where morality is reversed. This world is ruled over by an evil version of the Justice League, known as the Crime Syndicate, who in this RP are comprised of Ultraman, Owlman, Superwoman, Johnny Quick, Power Ring, Deathstorm, Grid, Sea King, Atomica, and The Outsider. There is a group opposing them called the Justice Underground, a good version of the Secret Society of Supervillains, comprised of heroic version's of the DC universe's villains. While they have not been the subject of many comics, I find the Justice Underground appealing. Therefore, I'm starting an RP focusing on them. We can make up completely new versions of them, as long as they're based on villains from the main DCU. They shouldn't just be good versions of villains, though. They need to have something unique about them that differentiates them. Here's a character form:
