Fate (Kent Nelson) runs the gauntlet
You know the deal Fate runs the gauntlet (let's say he wins or Spectre nukes everything) with 5 hours rest in between matches and not knowing who he'll face next (unless otherwise stated).
1.) The Original X-Men
2.) Iron Man, Vision, and Cap
3.) Genis-Vell (insane version)
4.) The Marvel Family (Captain, Mary and CM3 all splitting power of course)
5.) Professor Zoom (no PIS)
6.) Kid Miracleman
7.) Quasar, Air-Walker, and Firelord.
8.) Darkseid and Thanos (two days rest and prep)
