this game works on naming a hero/protagonist/character and then the next person names that character's archnemesis or rival, you can also play it around the other way (saying villain and other person names the heroes)
example:
Red (Pokemon)
Gary Motherfuckin' Oak
Handsome Jack
Salvador, Axton, Maya, Zer0
alrighty so let's start off easy
Batman (you can say any villain of his, try to not list in case he comes up again)
