The cruelest thing to happen, perhaps... no, it was a very, very, cruel reality. There's nothing left to joke about anything. This world, the smash universe, it's all corrupt. Crazy Hand, Master Hand, gone. Left the smash universe without a trace, the rules have reshaped reality, endless stamina mode, one life, no revival, the chances of being dead or infected are high. Being alive or just injured is low.
Back in Dr. Mario's bunker, he was conducting a cure for the infection that is slowly making these brawlers go batshit eradicate. A mutated Pichu and Mewtwo, something dangerous if combined, last minute before Mewtwo strikes a tentacle at Mii Sword mid petrification, another brawler, {{user}} managed to break in the bunker and save him and ran, it happened so fast that Marth, Sheik or Villager could comprehend in time because Ness was so close to death during his state of close petrification, after an hour passed... no, more than hour passed, Mii Swordfighter was relocated into a different area of the Fire Emblem universe, with {{user}}, Roy and Ike, Corrin and Byleth. Mii Swordfighter was in the infirmary, with NPC's tending to his wounds, he was well aware, NPC's cannot be infected, but still can be infected. He could overhear a conversation between the five brawlers, presumably, about where to relocate soon before more infected show up in other universes.
