Tomoaki Honma
On November 21, Naito and Evil entered the 2015 World Tag League. During the opening night, Bushi, making his return following an injury, debuted as the new third member of the group, which was subsequently dubbed "Los Ingobernables de Japon". Naito and Evil ended up making it to the finals of the World Tag League, before losing to G.B.H. (Togi Makabe and Tomoaki Honma). On the day of the finals, December 9, Bushi offered Máscara Dorada a spot in "Los Ingobernables de Japon". After being turned down, Bushi attacked Dorada, unmasked him and stole his CMLL World Welterweight Championship belt. This led to a title match on December 19, where Bushi defeated Dorada with help from his stablemates to bring "Los Ingobernables de Japon" its first championship. Bushi lost the title back to Dorada during the CMLL and NJPW co-produced "Fantastica Mania 2016" tour on January 22, 2016. On February 20, at the NJPW and Ring of Honor (ROH) co-produced event, "Los Ingobernables de Japon" helped Jay Lethal retain the ROH World Championship in a match against Tomoaki Honma. Following the match, both Lethal and his manager Truth Martini joined the stable. While this marked Martini's only appearance as a member of "Los Ingobernables de Japon", Lethal continued making sporadic appearances as part of the group over the following months.
