Ricky Mandel

Mathey debuted on Lucha Underground in a dark match on October 15, 2014 in a losing effort to Hernandez as a jobber. He would however, qualify for the Aztec Warfare match for the Lucha Underground Championship, but was unsuccessful. During the first two seasons of Lucha Underground, Mandel also wrestled under a mask as Trece, one-third of the Disciples of Death Trios team, along with Barrio Negro, and Sinestro de la Muerte, though Mandel was not acknowledged to be the man under the mask. On the April 20, 2016 episode of Lucha Underground, the character of Trece, along with Barrio Negro, was killed off, when Sinestro de la Muerte turned on his partners, and ripped their hearts out. Ricky Mandel has since returned as a Johnny Mundo devotee, changing his ringname to Ricky Mundo.
