On the December 15, 2011 episode of WWE Superstars, Loa came debuted under the name Camacho as the new enforcer of Hunico. Hunico and Camacho first teamed together on the April 26, 2012 episode of Superstars where they beat the Usos. Camacho made his pay-per-view debut at Over the Limit, where he was defeated by Ryback in a singles match. Camacho then began appearing on NXT; he made his NXT debut on the July 4, 2012 episode, first losing to Seth Rollins but emerging victorious later that episode in a six-man tag match while teaming with Hunico and Michael McGillicutty against Rollins, Bo Dallas, and Tyson Kidd. On the next episode of NXT, Camacho defeated Kidd in a singles match following a distraction from McGillicutty. On the pre-show of Money in the Bank, he and Hunico lost to the WWE Tag Team Champions Kofi Kingston and R-Truth in a non-title match. At Raw 1000, Camacho, along with Hunico and four other wrestlers, attempted to ambush Kane to make a statement, but The Undertaker's return resulted in the Brothers of Destruction disposing of all six would-be attackers. With Hunico out injured, Camacho continued to compete on NXT; after a $5,000 bounty was promised to anyone who could put Big E Langston "on the shelf"; Camacho attempted to claim the bounty in late-2012 so that he could "get Hunico out of Mexico", but he was squashed by Langston. On April 4, 2013, Camacho reunited with Hunico at the WrestleMania Axxess live event. On the November 6, 2013 episode of Main Event, he and Hunico made their first televised tag team match since July 2012, losing to The Usos. He and Hunico then started a feud against The Ascension, defeating them in a non-title match, but were then defeated in an NXT Tag Team Championship match.
Once Hunico started portraying Sin Cara again, Camacho started to wrestle solo on NXT. Camacho scored a rare victory over the returning Oliver Grey on the March 13, 2014 television tapings. His last feud in WWE was with Adam Rose on NXT, which began when he attacked one of Rose's followers after a match and ended at NXT TakeOver, when Camacho lost to Rose. On June 12, 2014, Camacho was released from his contract.
Camacho, under the name Tanga Loa, made his return to WWE as a part of The Bloodline at Backlash France on May 4, 2024, assisting Solo Sikoa and his brother Tama Tonga to defeat Kevin Owens and Randy Orton in a tag team street fight. Loa made his WWE in-ring return on the May 31 episode of SmackDown, teaming with his brother Tama to defeat The Street Profits (Angelo Dawkins and Montez Ford). On the August 23 episode of SmackDown, Solo Sikoa had Jacob Fatu relinquish his share of the titles to Loa so that Fatu could be Sikoa's personal enforcer. On the October 25 episode of SmackDown, Loa and Tonga lost the titles to The Motor City Machine Guns (Alex Shelley and Chris Sabin) after interference from Jey Uso, ending their reign at 84 days.
