Underground Sound - Lucha Underground recap for October 3, 2018

Outside the temple, Melissa Santos asks Aerostar what has happened concerning Fenix. Aerostar says he should not have undone what time had already done, but Fenix was his friend. However, when Catrina absorbed Fenix's life force, her evil spirit infected him like a disease, and he wasn't supposed to get it back. He says that Catrina has changed him into something evil. Melissa says she can save him, but Aerostar says he is already gone, and he is sure of that because he has seen the end of everything.

The Rabbit Tribe (Paul London, El Bunny and The White Rabbit) beat Ivelisse, XO Lishus and Joey Ryan after The White Rabbit applies a Mandible Claw to Joey Ryan with a pristine white glove. When he pulls his hand out, blood is on the fingers of the gloves.

Announced for Ultima Lucha Cuatro: Mil Muertes vs. The Mack in a Death Match! El Dragon Azteca Jr. vs. Fenix in a two-out-of-three falls match! Pentagon Dark vs. Marty "The Moth" Martinez for the Lucha Underground Championship!

Son of Havoc beats Killshot with a surprise schoolboy pin. After the match, Killshot hits Son of Havoc with a running boot to the face before wrapping his dog tags around his fist to punch Son of Havoc in the face. Killshot then removes Son of Havoc's mask, and Antonio Cueto shows up to tell him that the mask means as much to Son of Havoc as it does to him. He says their masks not only hide their faces, but symbolize the new warriors that both men have become. Antonio Cueto then puts both men in a Mask vs. Mask match at Ultima Lucha Cuatro.

Marty "The Moth" Martinez shows up with Chelsea Green, now wearing a cape instead of a T-shirt. Marty says this journey started three years ago when an "egotistical, egomaniacal" Sexy Star embarrassed his family, and that he has not forgotten. This is why he sent Chelsea Green - now known as Reklusa - after her. Reklusa pulls Sexy Star's mask out from behind the Lucha Underground Championship on Marty's waist. He then reveals that Reklusa was the one terrorizing Sexy Star for the past year, and that she beat Sexy Star to the point that her mask was all that was left at Marty's command. Marty then says there is one person who humiliated him more than Sexy Star ever could: Pentagon Dark, who broke his arm. He responded by taking the Lucha Underground Championship from Pentagon Dark. He then mentions one other person who is also more beautiful, and looks at ring announcer Melissa Santos - who gives him the Pentagon Dark "cero miedo" hand motion - before addressing his sister Mariposa. He says that Mariposa forced him to focus when he was at his lowest point, and says he owes her. He then says that his first Lucha Underground Championship defense will be against Mariposa, not Pentagon Dark, and invites her to the ring to play just like when they were kids.

During the beginning of the next match, it is announced that Marty "The Moth" Martinez has requested to Antonio Cueto that this match be no-disqualification, and that Antonio Cueto has agreed.

Marty "The Moth" Martinez retains the Lucha Underground Championship against Mariposa in a no-disqualification match with a package piledriver after mocking Pentagon Dark followed by interference by Reklusa. After the match, Marty says it was Mariposa who showed him the focus to beat her, and that it will be the same focus that keeps him Lucha Underground Champion. He then tells Pentagon Dark that he wants to challenge him at Ultima Lucha Cuatro in a Cero Miedo Match, and that when he beats him in his own match, he will dedicate the match to him, then breaks Mariposa's arm with Pentagon Dark's own arm breaker and dedicates it to him as well. Pentagon Dark then shows up with a steel chair, and Marty retreats after ducking a chair shot. Pentagon then asks him if he is challenging him to a Cero Miedo Match before telling him that he accepts and that he promises to break his bones.
