Humilde Jr. was part of the first generation of wrestlers from Mr Tempest Professional Wrestling School. His first experience in the ring was on September 21, 2013 in San Luis Río Colorado. He honed his skills with Principe Negro, but he also was guided by Proximo and Genio Del Aire. Before taking his father's mantle, he competed under the name of Exxce for a few appearances. His actual debut was in the traditional New Year's Event in Arena Nacionalista. He took over the name of Humilde Jr. in Arena Coliseo on April 6, 2014. He had a feud against his own father Humilde.
By late 2018, he was repackged as part of the rudo the tag team Los Fray Diablos, which has been incarnated by several wrestlers over the years in Mexicali. He accepted to don the Fray Diablo mask to demonstrate he could earn opportunities by his own talent and not for just being the son of a prominent luchador in Mexicali.
Along with his then tag team partner were introduced as brothers from Guadalajara, Jalisco with a worked storyline. They were a great tag team until their separation. Fray Diablo Jr. endured under this gimmick and was well received by the fans. Eventually, Fray Diablo Jr. revealed to be Humilde's son.
On April 29, 2023 he decided to go back as Humilde Jr. Some of the reasons are because there are new projects and his father's retirement is near and he wants to honor him.
