Westside Mafia; faux retirement and CWS (2016–2017)
On January 14, 2017, Concepción and the Westside Mafia addressed the crowd in an event where he announced a premature retirement citing lingering injuries and in the process vacating the WWL World Heavyweight Championship. However, later that night he made an appearance in Championship Wrestling School, a developmental promotion that had recently received the support of a returning Negrín, pursuing vengeance against BJ and attacking other heels. Prior to this, the promotion had already hinted his presence by publishing a darkened silhouette of him on January 13, 2017, promoting him as a surprise that would face Negrín and his La Sociedad stable. This appearance was followed by a hiatus. On March 18, 2017, Concepción reappeared in the CWS under a mask as part the Zona Urbana event, antagonizing Negrín and La Sociedad.
Return to WWL and the "blessing of El Nazareno" (2017–present)
The character of El Nazareno was born after fans used the term as a non-swearing insult in WWL's social media to criticize his jump to CWS, going viral and inspiring a number of memes superimposing his face in religious icons. Concepción adapted this nickname by adopting cross-themes gear and making use of angelic music while making promos and employing the catchphrase El Nazareno los bendice. In anticipation to his return, WWL began playing Ismael Rivera's eponymous religious salsa song in segments with the Westside Mafia, with some of its lyrics becoming additional catchphrases, in particular those making reference to "tak care of your friends" and "extend your hand to the fallen". On July 15, 2017, 450 defeated Joseph Cruz "J.C." Navarro in a first contenders match, stole the WWL World Heavyweight Championship belt and rebranded himself the Mecha Wolf 450, also turning on the Westside Mafia. After Concepción relocated to Florida, he began making appearances in the independent circuit of the region. He also debuted a parallel character, Dark/Evil Nazareno, which allowed him to perform as a heel under the same character. On January 10, 2018, this dark persona interfered on behalf of Angel Fashion in a Pro Wrestling 2.0 match against 450, leading to the creation of a stable known as The Holy Fashion along Carlos Cupeles. On February 9, 2018, Concepción made his debut for Cleveland Knights Championship Wrestling, helping Fashion win the "Chase for the Case" six-man ladder match. At CKCW, the remaining two members of Tercera Generación became part of The Holy Fashion. The group began a list of "Hall of #Blessed" wrestlers, which compiled those laid out by the group. "Sensacional" Roger Díaz and Justin Dynamite were the inaugural members. After weeks of stalking 450, Fashion faced him at Pro Wrestling 2.0 on February 13, 2018, where Nazareno and Cupeles joined the latter to make the former the "latest inductee" into the Hall of #Blessed by jumping him.
