"eleXtion"
Every mutant is trying to campaign (and some will battle) to decide who will lead the Mutant Nation. This could be a way to get mutant villains (Mystique, Azazel, Shaw, Daken, Omega Red, S.King, Emplate) into cooperating in which they are promised for a chance to be leader if they enlist into the X-Nation. Tie-ins could be several Heroes, Villains, Businesses, and other groups are helping their candidates and sabotaging others so they could have a pull in the aftermath of the election.
Political counterparts lol: Jean (Hilary), Storm (Obama), Emma (Female Trump), Beast (Bernie Sanders), Colossus or Magik or Omega Red (Vladimir Putin), Namor (Bill Clinton), Mystique (Nixon) Xavier or Magneto (Ronald Reagan), Hope (Sarah Palin)
Oh, it could also be a video game! (In Tekken 3 Voice) "King of Iron Mutant Tournament"
