War Of The Supremes!
Eternity already ordained Pym as the Scientist Supreme and stated that Reed was the Explorer and Tony the Engineer.
Loki disguised as Eternity in cahoots with Doom and Ultron manages to persuade all four men that the others have become possessed by demons and plan to destroy the Earth via enchantments and doctored film media, they manage to make the lie look real. And give all four men their Titles.
Sorceror Supreme-Dr Strange (Hands Healed)
Scientist Supreme-Hank Pym
Reed Richards- Explorer Extreme
Tony Stark- Engineer Extreme
Eternity/Loki heals Strange's hands and says that although the others may try to persuade them that they are innocent that they can't be trusted. Loki/Eternity then murders Pepper Potts, Sue Richards, Clea and Jocasta and all her backup files. To enrage the men into a revenge battle to the death.
All four are Bloodlusted but have two hours of prep.
No PIS or CIS
Battle takes place in New York but Pym resides in the Infinite Mansion.
FIGHT!
