On March 20, 2010, he debuted in the International Wrestling Association (IWA), winning his contest in the first round of a tournament to determine the first contender of the cruiserweight-based Xtreme Combat Division.

On December 15, 2012, the heels lost their masks in a bet between both teams, revealing their identity as Ortiz, Cupeles, Real Michael, Two Face, Joseph Cruz “J.C.” Navarro and Oscar Anderson.

[7] On May 11, 2017, WWL aired a segment where Mendoza overheard a conversation between Mr. 450 and Konnan, members of an invading faction known as La Junta de Control (lit.

Both debutants were unable to attend WWL's next card due to pre-existing arrangements to participate in Cleveland Knights Championship Wrestling's (CKCW) Vanished Empire event, where he faced Matt Justice.

Instead, the promotion ran an angle were the leader of the Puro Macho stable and La Junta's COO, Manny Ferno, visited his grandfather's gym and attacked his brother, Christian Ortiz, who was training to become a wrestler.

On June 24, 2017, Mendoza made his in-ring debut by defeating Puro Macho member "J.C." Navarro, but the group once again attacked his brother and broke one of his arms as part of the storyline.

Mendoza and Pérez, now collectively known as La Tercera Generación, defeated the unified Global Force Wrestling/Impact Wrestling World Tag Team Champions Ángel Ortiz and Mike Draztic in the first confrontation between groups.

[11] 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, in the process turning on the faces.

[11] After months of hiatus caused by hurricane Maria, WWL returned with Juicio Final in April 2018, where Mendoza teamed with Vargas in a loss to La Hermandad.

By May 2018, Tercera Generación had become involved in a series for the World Tag Team Championship against Primos Meléndez and titlists Westside Mafia, coming up short in their opportunities.

In Destino Final 2018, Mendoza suffered a fibula fracture during a three-way match (which included both his teammate and new champion BJ) for the WWL World Heavyweight Championship.

[18] Despite being reduced to a secondary role and being hounded by an unknown masked assailant, Mendoza scored successful defenses over Roger (twice, in regular and iron man matches) and Justin Dynamite.

In the final event held under the WWL brand after the promotion rebranded to Liga Wrestling, El Fin, Mendoza won a three-way match over Fashion and BJ to win his second World Heavyweight Championship.

Instead, Ortiz participated in CKCW's anniversary show where "Sensacional" Roger Díaz retained the heavyweight championship of local independent promotion CWA in a fatal four-way match.

In the interim, he made an appearance for NEW (an independent promotion organized by WWL co-worker Nelmarie "Roxxy" Tirado) defeating one of his students, the posh masked wrestler known as El Gentil.

While the larger companies remained in a hiatus, Ortiz made an appearance in the season closer of CWA, where he attacked Díaz and in subsequent skits between both a challenge was issued.

Mendoza's final abroad appearance of the year took place on December 6, 2019, at CKCW's Obliteration, where La Marea faced Star Roger and BJ.

Ortiz is a third generation wrestler, with his grandfather being Salvadoran legend Salvador Pérez "El Vikingo", who wrestled in Puerto Rico while competing with WWC (then Capitol Sports Promotions) during the 1980s and 1990s.

Ortiz, a medalist in the Liga Atlética Interuniversitaria de Puerto Rico as an amateur wrestler, began training there interested in following the family's trade.
