This is the biggest accomplishment in IWT, The World Title. Although the word Heavyweight is used in its name, any Male superstar can attain this prize.
As there is currently no brand split with IWT, the champion must turn up to both Power and Pass Out. Kenzo Suzuki was the first World Champion winning a 12-Man Tournament at IWT One Night Stand.
Following 2 months of inactivity, Biff defeated Kenzo to win the World title following the assistance of the special guest referee Danny Jackpot. GM Suspect intervened later causing Biff to defend his title immediately against his "Chosen One" Oshujax who made quick work of Biff and is the current Champion.
