The original title belt was a variant of the Big Gold Belt, since then-president Richard Negrín was a fan of the design. On April 21, 2013, at the inaugural event of the WWL, José Torres, working as Monster Pain, defeated Bobby Lashley to win a battle royal and become the inaugural World Heavyweight Champion. The title soon received its first international exposition by being featured, but not defended, in a match where he teamed with Matt Morgan and Jeff Jarrett in a win over the Trios ChampionsLos Psycho Circus as part of Asistencia Asesoría y Administración's Triplemanía XXI event. On September 6, 2013, Torres defended the WWL World Heavyweight Championship, retaining after losing a countout to John Morrison in Saltillo. Two days later at Monterrey, he retained by disqualification in a rematch, winning when Morrison removed his mask. On March 7, 2014, he retained the title by wrestling Mil Máscaras to a no contest at Veracruz. Two days later, Torres defeated Carly Colón and Chavo Guerrero in Mexico City to remain champion. On October 18, 2014, at the show that marked the return to the Puerto Rican home base known as Insurrection, Pain lost the title against Shane Sewell. The Canadian served as transitional champion, eventually losing to Alberto El Patrón. A controversial finish was used to justify stripping him of the title. Negrín later revealed that Rodríguez had created a creative hindrance by refusing to lose or film promos throughout his run.
Reintroduction
On March 23, 2015, the promotion entered a hiatus without crowning a champion, and when it returned the original belt was replaced with a new diamond-shaped design, also marking a new approach that focuses on hosting cards at Puerto Rico instead of touring. Hiram Tua won the vacant title and defended it throughout a change in administration that saw Savio Vega purchase the promotion from Negrín. Tua dropped the title to Superstar Ash at Christmas in PR, the promotion's 2016 season closer. However, the relationship between Rivera and Negrín deteriorated and the latter began sponsoring a small independent named Caribbean Wrestling School. At Evolución, Superstar Ash stated during a promo that he was retiring and vacating the title due to nagging leg injuries, but appeared in the former president's promotion that same night. The promotion responded by giving the title to Mr. Big, a then midcard veteran who was amidst a major angle where he was forced to become disciplined in order to return to the mainevent after almost a decade. He was booked as a rebellious and dominant champion for the following months, retaining the title with relative ease and only responding to Vega. Parallel to his feuds was an angle where his former tag team partner Blitz tried to convince Big that he was on the wrong side, only to be attacked. After La Junta de Control a stable lead by Konnan was introduced as the new power and storyline owner of WWL, firing Vega in the process, the group actively pursued replacing him with a corporative champion, bringing talent from abroad. Blitz managed to be named the special referee of Big's first defense under the new regime and aided him retain over Mr. 450 and Willie Mack. After the tag team reformed as Los Rabiosos, general manager Miguel Pérez Jr. was tasked with dethroning him by any means necessary. Mr. 450 was the first to get a titular rematch, but the contest ended in a double disqualification due to outside interference. A returning Concepción, now known as El Nazareno, also failed to win the title after refusing to cheat despite Pérez giving him carte blanche to do so.
Mr. 450's international tour
On July 15, 2017, Mr. 450 defeated Joseph Cruz "J.C." Navarro in a first contenders match and stole the WWL World Heavyweight Championship belt, bringing it on board an airplane. Afterwards, the self-proclaimed champion would carry the title in his foreign presentations, beginning the following day when he headlined in a trios match at the Arena Nacionalista in Mexicali. This was followed by an appearance in Wrestling Superstar's Lucha Conquest event, held at Orlando, Florida. On August 5, 2017, Big was given the original belt to replace the stolen one and defended it in a three-way against the latest contenders that ended without a winner, after which Mr. 450 took that one as well and self-proclaimed himself the "Undisputed World Heavyweight Champion". Although the promotion entered a forced hiatus after hurricane Maria passed over Puerto Rico in September 2017, 450 retained the unofficial WWL World Heavyweight Championship by defeating Skalibur on October 29, this as part of the 28th Anniversary of the Arena Nacionalista in Mexicali. On March 24, 2018, 450 made an appearance with the second model of the title while challenging Star Roger for Champion Wrestling Association's World Heavyweight Championship. Mr. Big also made an unannounced appearance, attacking both and reclaiming the belt. Despite this, 450 retained control of the original title. After defeating Mr. Big at Juicio Final to formally become champion, more defenses abroad followed. On June 23, 2018, Mecha Wolf retained over Jake St. Patrick in a Coastal Championship Wrestling card held at Coral Springs, Florida.
