The DDT Iron Man Heavymetalweight Championship is a championship in DDT Pro Wrestling. The Ironman Heavymetalweight Championship is defended anywhere against anyone, even during non-title matches or tag team matches, under the same 24/7 rules that applied to the WWF Hardcore Championship (if there is an official DDT referee present, the title can be won and lost).
The championship is often used in a comedically fashion and as such wrestlers have won or lost the belt via games of Rock, Paper, Scissors and the championship was won by a fan during an auction. Notable champions have included a dog and a ladder.
The championship is regularly fought for in 10-minute battle royals, during which the title can change hands a number of times and the person who has the belt when the time limit expires can leave as champion. This is ironic as under the 24/7 rules the champion could be defeated for the belt immediately after the match finishes.

Non-existent[]
- Misutero - An "invisible wrestler" i.e. non-existent. Opponents sell moves of a wrestler who isn't there, and the title is held by nothing and no-one but the wrestlers and referees act as if they can see and pin the "invisible wrestler". Muscle Sakai "won" the title from this "invisible wrestler" by using a "ray gun" and "infrared visor" to shoot the "invisible wrestler", winning the belt on a KO decision.
