If you're doing a knockout tournament with 42 combatants, you're not going to have an even number of finalists. If half the combatants are eliminated in the first round, you're left with an odd number, meaning one combatant won't have an opponent. If you intend on using 42 combatants, you will have to introduce some characters in a later round.
