After Matelson used the Víbora character in Lucha Underground, he started to use the character in the independent circuit. He changed the name to Luchasaurus after fans chanted that during his Lucha Underground debut.[11] On November 17 and 18, Matelson wrestled for House of Hardcore under the new gimmick and ring name Luchasaurus, defeating Alex Reynolds on the first night and winning on the second night in a three-way by defeating Matt Riddle and Willie Mack.[12][13]

On May 25, 2019, Matelson debuted for All Elite Wrestling (AEW) at Double or Nothing as a part of the pre-show Casino Battle Royale. He lasted until the final three, before being eliminated by Adam Page.[17] Three days later it was revealed that he had signed with the company full-time as Luchasaurus.[18] He would then go on to form a tag team with Jungle Boy as he managed him at Fyter Fest and teamed up with him at Fight for the Fallen in a Triple Threat tag team match involving The Dark Order and Angelico and Jack Evans in a losing effort. At All Out, Luchasaurus alongside Jungle Boy and Marko Stunt would debut as the stable "Jurassic Express". On the August 18, 2021 episode of Dynamite, Jurassic Express had a match for the AEW World Tag Team Championship against the Young Bucks, but failed. On the January 5, 2022 episode of Dynamite, the Jurassic Express defeated the Lucha Brothers to win their first AEW World Tag Team Championship.[19] The team would then defend the titles against the Young Bucks and reDRagon (Kyle O'Reilly and Bobby Fish) in a triple-threat tag team match at Revolution.

After Jungle Boy and Luchasaurus lost the titles on a special edition Dynamite named Road Rager, Cage turned on Jungle Boy, with Luchasaurus also turning heel when he joined Christian Cage.[20] At the start of his alliance with Cage, Luchasaurus was presented as a “monster heel” and started squashing multiple opponents within minutes, all at Cage’s direction.

At Fyter Fest week 2, Luchasaurus turned on Christian Cage to realign with Jungle Boy, however, this was also a short-lived reunion. At the All Out event, Luchasaurus cemented himself as a heel by attacking Jungle Boy once again and solidifying his alliance with Christian Cage. On June 17 at the premiere episode of Collision, Luchasaurus defeated Wardlow to win the TNT Championship.[21] Luchasaurus would later lose the title to Christian Cage in a three-way match that also involved Darby Allin on the September 23 episode of Collision.

In late February and March 2015, several former NXT trainees previously working within the WWE developmental system alleged misconduct by head trainer Bill DeMott, with Devlin and Brandon Traven publicizing complaints which they claimed they had submitted to WWE management about DeMott back in March 2013, when they were still employed with WWE.[26][27] Meanwhile, other ex-trainees like Briley Pierce and Derrick Bateman also made allegations in 2015,[26][27][28][29] while previous allegations made in 2013 by Chad Baxter and Chase Donovan were also noted.[30] They accused DeMott of making trainees perform dangerous drills,[26] physically assaulting and bullying trainees,[26][27] using homophobic and racial slurs amongst other derogatory terms,[27][30] and condoning sexual harassment.[28] WWE released statements regarding some of the claims that came to light in 2013 and 2015, saying that investigations were done and no wrongdoing was found.[26][30] On March 6, 2015, DeMott denied the allegations, but resigned from WWE "to avoid any embarrassment or damage" to the company.[28]
