For the most part, I find Pulp City's Supremes to be pretty damn original and quite special - it's one of the things that attracted me (and a lot of other people no doubt) to the game) - as anyone who is conversant in Superheroes and Comics History knows - there are certain Archetypal Hero/Villain Classes.
The Archer, the "Superman" (for want of a better word), the Gadget Hero, the Power Armoured Hero etc, etc.
At the end of the day though, there are no truly original ideas anymore - just really REALLY cool ways of presenting them.
Which us Fans KNOW
Pulp City does in spades!
