MCU's UFC tournament
These MCU fighters compete in a UFC-style tournament against each other, within their own "weight class". Standard UFC rules apply: can win via KO or tap out, no groin hits or fish hooks etc., 3x 5 minute rounds, if no winner by end of 3 rounds then it goes to judges' decision, etc.
Fighters aren't allowed any weapons or armor unless specified. Fights are pure h2h, no eccentric powers allowed. Who ends up the tournament champion for each weight class?
