Mephisto (born December 10, 1968) is the ring name of a Mexican luchador enmascarado, or masked professional wrestler and currently works for Consejo Mundial de Lucha Libre (CMLL).

His real name is not a matter of official record as he is an enmascarado, which by lucha libre traditions means that his personal life is kept secret from the general public.

On March 22, 1999, Astro Rey Jr. won the Mexican National Welterweight Championship from Arkangel de la Muerte and defended it several times during his 19-month reign.

The storyline was that El Satánico used his supposed "satanic powers" to turn the tecnico (face) Rencor Latino into one of his "minions", the rudo (heel) known as "Averno" ("Hell") in a televised segment.

After this turn was completed they were joined by Mephisto, formerly Kahoz Jr. and Astro Rey Jr., but unlike Averno, no references to his previous identities were made at the time.

A year later, September 2002 at the CMLL 68th Anniversary Show, the two groups faced off in a steel cage match to determine who had the rights to the "Los Infernales" name.

[8] After the steel cage match the feud between the two groups more or less ending, the splinter faction changed their name to Los Guerreros del Infierno ("The Warriors of the Inferno").

Instead Los Infernales did win a tournament to become the number one contenders for the CMLL World Trios Championship but lost to champions Black Tiger III, Dr. Wagner Jr. and Universo 2000 on August 1, 2003.

[12] Mephisto and Averno defeated Atlantis and Blue Panther for the CMLL World Tag Team Championship in a heated match on April 2, 2005.

[4] Their most prominent defense was on the last Arena México show of 2005 when they defeated El Hijo del Santo and Negro Casas in the main event.

[16] On February 15, 2009, Mephisto unsuccessfully challenged Místico for the CMLL World Welterweight Championship on a New Japan Pro-Wrestling show in Sumo Hall, Tokyo.

On August 16, 2010, it was announced that Mephisto was one of 14 men putting their mask on the line in a Luchas de Apuestas steel cage match, the main event of the CMLL 77th Anniversary Show.

[29] Mephisto participated in the 2014 La Copa Junior VIP tournament in the first qualifying round that took place on the September 26, 2014 Super Viernes show.

[34] In January 2016, Mephisto returned to NJPW to take part in the Fantastica Mania 2016 tour, during which no reference was made to his previous association with Bullet Club.
