First, take your pick of a super power or power set (yeah, I'm being more generous than you usually get with this kind of question) and then describe what crazy fun fantasy you'd fulfill with it.
At least CHOOSE that power/power set now before even reading the next part... (scroll down)
After describing your crazy fun power fantasy, give the situation a big dose of psychological realism. How do you think you would REALLY react to suddenly discovering you had this power? Would you tell anyone? Would you REALLY try to do any good with it? What would you say if people found out? (Answer any or all of these questions or just give some general thoughts about how you think the situation could realistically play out.)
I usually go first when introducing topics like this, but I don't want to influence any thoughts accidentally. So who wants to jump in first instead?
