Evil Mythic Pathfinder
Never heard of Sinister Squad.
Of course, any realistic bad guy thinks of themselves as a good guy. I recall one of Suicide Squad characters even had a family he was happy to get back to at the end.
So the question at this point then, how would you feel about a very heavily modified system of 3.x/pf1?
I'd love to see how well it runs at higher levels of play.
