PHIGHT! ON THE STAGE! / Alien Stage X PHIGHTING! AU

After a concerning amount of deafening construction noise, Medkit finds out they've been building a stage for concerts and sports events, but now forced to hold a competition to the death, yet he only realized later that he was being drafted to join the tournament, fearing his own demise. The stage was set, the architecture felt as if robots had carefully placed every miniscule light and decoration, yet the inphernal who loses against their rival in a round won't come out of the stage alive.
As the inphernals each face off to see who can get the most points, it's almost like a tournament; 32, 16, 8, 4, 2... The numbers going down the more rounds pass. Yet what or who will Medkit face in these rounds?
