List of King of the Cage champions
This is a list of King of the Cage champions at each weight class. KOTC is a USA-based mixed martial arts organization that was founded in 1998.
The weight division system of KOTC is divided up in accordance with the Unified Rules of Mixed Martial Arts, but with some variations.
KOTC has chosen to name its 145-pound division "Bantamweight", its 135-pound division "Flyweight" and its 125-pound division "Light Flyweight". KOTC also takes advantage of the rarely used Super Heavyweight division for fighters exceeding the 265-pound weight limit of the Heavyweight division.
In addition to these variances, KOTC also employs three exclusive weight classes that are were not specified within the Unified Rules of Mixed Martial Arts : a 165-pound "Light Welterweight" division, a 230-pound "Cruiserweight" division, and a 185-pound "Light Middleweight"' division. These divisions were later introduced into the Unified Rules of MMA, with "Light Welterweight" being called "Super Lightweight".
