Yes, each character offers very different gameplay than the core characters from what I can tell.I haven't seen all of them used yet, but there are a couple that have 'helper' characters that can be leveled up on their own (each takes up the entire first level up 'box', so you have to take them as your first level up, and you can't 'overwrite' that box), and each of the others has their own odd sets of mechanics (I believe one has powers that are affected by the current time symbol, for instance, while the other shifts between two modes).
