The Mysterymen are a team (more like a gang, really) of blue-collar superheroes who can't make the big leagues because of a variety of flaws: mediocre powers, ridiculous (even for superheroes) costumes, behavioural problems and severe character flaws, terrible reputations, etc.
Unable to find a team who would take them, they formed their own. They've been nicknamed the Dirty Thirty because at their height they had around that many members, but time and a high casualty rate has brought that number down a bit. in fact they have the highest casualty rates of any superhero team in existence, but they also have the highest kill ratio too - they may not be powerful, but they don't hold back what they do have.
