Used by Choujins to settle disputes. The rules are similar to puroresu and mixed martial arts, except eye poking, biting, and attacks to the crotch are allowed.
Rules
They are basically limitless one-fall matches but with no weight classification system. At first referees were put in the rings, but as the series progressed the rulings and decisions were made from outside of the ring so as to not interfere with the fight. Matches are won by forcing the opponent to give up, KO (this often means death), 3 Count Fall, and a 20 Count on the occasion of a Ring-Out. In Tag Matches the elimination of both opponents is usually required, but occasionally eliminating only one is allowable.
Violations
Weapon use and a third man trespassing during a one-on-one competition is strictly prohibited. Techniques that recquire the ringpost or ropes (ex: Choujin Hanging, Royal Stretch) are allowed, but when the ringposts are pulled out or the ropes are torn and used against the opponent they are viewed as weapons and therefore against the rules. However, weapons that are part of a Choujin's body (Warsman's Bear Claws, Buffaloman's Long Horns, Prisman's Rainbow Shower, etc.) are acceptable. Likewise, attachments to the masks of masked Choujins (ex: Kinnikuman's head fin and Robin Mask's horn) are considered part of their bodies and therefore not an infringement of the rules. The spikes on Neptuneman's vest also seem to be included in this.
