KO-D無差別級王座
There are many Open-weight tournament transfers in professional wrestling. Some wrestling promotions have officially-designated Openweight Championships (IWGP U-30 Openweight Championship, GHC Openweight Hardcore Championship, NEVER Openweight Championship, KO-D Openweight Championship, MLW National Openweight Championship) while other promotions ignore weight classes to the point that most, if not all of their championships are effectively openweight. For example, the WWE Championship, traditionally promoted as a heavyweight title, has been held by wrestlers billed as weighing as little as 170 lbs., well below the traditional minimum weight for a wrestler to be classed as a heavyweight.
