For a time, the title was defended in the W*INGpromotion in Japan as the W*ING World Junior Heavyweight Championship. Originally, the title was used to push a wrestler that the promotion was interested in, becoming a stepping stone on the route to the WWC Universal Heavyweight Championship. A pattern was followed where these talents would win the Junior Heavyweight Championship first, followed by tertiary and secondary titles, before progressing to the main event. By the 2010s, promoting up-and-comers became a secondary function, with the title now being used to appease journeymen and occasionally punish wrestlers that failed to draw. Independent wrestlers and veterans such as Tommy Diablo would exchange the title, which served as a perpetual card opener.
2017 international tours
After defeating Ángel Pérez to win the title for the first time and aware that the it was no longer being used to push new or young talents, O.T. Fernández requested permission to take it abroad, citing interest in returning it to its original format and reputation by stating that he was "going to keep representing and showcasing the title with the best of abilities to keep elevating this championship back to its old roots." In May 2017, he took the title on the Dragonmanía XII tour held at the Arena México, marking the first time in years that the title was exposed internationally, tough it was not officially defended. On July 8, 2017, Fernández successfully retained the title over Aero Boy in a Cleveland Knights Championship Wrestling card held at Ohio. His reign continued gathering outside exposition by making an appearance in a WAPA-TV comedy named "Such is Life". Fernández's successor, Ángel Cotto, continued the trend by defending the title at Chicago as part of IWC's Halloween In Your Face event, retaining against Julio "Vértigo" Rivera by getting himself disqualified.
Postmortem, IWA Florida (2018–present)
After the title was quietly retired, the incumbent left WWC with the belt in his possession. On October 17, 2018, Cotto debuted in the rival World Wrestling League, where the fact that he never lost the WWC World Junior Heavyweight Championship was worked into a storyline that saw him challenge WWL Super Cruiserweight ChampionMark Davidson. On November 12, 2018, the actual belt made an appearance in a video announcing his arrival to IWA Florida, itself a spinoff of WWC's longstanding competition, the International Wrestling Association. On December 7, 2018, the WWC World Junior Heavyweight Championship made its first physical appearance in WWL as part of Cotto's promotional skit for Black Xmas, where he felt short in his attempt to accomplish an extra-official unification. On December 17, 2018, IWA Florida announced that he would be exposing the title in an open challenge at Histeria Boricua 2019. As part of that event, Papi Nieves won the belt and was attacked backstage. This led to a formal feud against Cotto. Nieves’ reign ended on March 16, 2019, when he dropped the belt back to its former owner at the IWA Arena. Cotto would then take it to Chicago, appearing in Global Wrestling Stars’ Noche Xtrema event. Even when entering a tournament for the IWA Florida Tag Team Championship, his incumbency as champion was emphasized. When queried about carrying and defending the belt, Cotto said that he would return it to WWC if an “economic agreement is reached with Carlos Colón”. He continued being billed as the “incumbent champion” afterwards, making appearances in this role in August 2019.
