how are characters decided

Good question. It will be a Heroes vs. Villains tournament. Everyone pics 3 villains and 3 heroes to enter into the tournament. Now, doubtless everyone may disagree on certain names but I'm positive there will be a couple common votes for the same characters and the rest who may only get one vote will be selected at random to be in the tournament. I will encourag epeople newly suggesting their three heroes and villains to look at everyone who's posted before them so they can possibly choose a name already said and make the process less time-consuming.
