Volador Jr.
On March 30, 2018, Taven defeated Volador Jr. to win the NWA World Historic Welterweight Championship. He returned to Mexico in August of that year, starting out by losing the NWA World Historic Welterweight Championship back to Volador Jr. at the Negro Casas 40th Anniversary Show. Afterwards Taven and Volador Jr. joined forces they were both attacked by "Los Ingobernables" ("The Unruly"; the team of Rush and El Terrible). The storyline with "Los Ingobernables" built over the following month, with Bárbaro Cavernario replacing El Terrible due to an injury, to the main event of the CMLL 85th Anniversary Show. Rush and Cavernario defeated Taven and Volador Jr. on a "Lucha de Apuesta" ("Bet match"). As part of the storyline, Taven turned on Volador Jr., costing their team the match. After the match both Taven and Volador Jr. had their hair shaved off as a result. Taven, now bald, returned to CMLL for the 2018 International Gran Prix tournament. During the match, Volador Jr. took revenge on Taven for costing them their match and pinned Taven 45 minutes into the match. Taven returned to Mexico and CMLL once more in August 2019, this time as ROH World Heavyweight Champion, for the 2019 International Gran Prix tournament. For the second year in the row Volador Jr. pinned Taven to eliminate him.
