you have to unlock a super strength character by playing story mode on the villain side, which should happen in the first level you play with Clayface. other characters with it are Bane, Freeze, maybe Man Bat, but i can't remember. once you play through the whole story mode on the hero and villain sides and start doing free play, the game will always give you a superstrength character in the mix to use, same way it gives you at least one of every type you need: a mind controller, joker, poison ivy, etc.
i did have to specify which characters i wanted a few times though, like to get the bane backbreaker achievement or the mad hatter one.
