Último Gladiador  Gerardo Campos Poza (born March 28, 1978), better known under his ring name Último Gladiador (Spanish for "Last Gladiator") is a Mexican "Luchador" "enmascarado", or masked professional wrestler. Campos currently works for the Mexican professional wrestling promotion Lucha Libre AAA Worldwide under the ring name Demon Rocker as a part of the group "Los Inferno Rockers". Campos has previously wrestled under the name El Potro as well as being the first wrestler to play the masked Mega character for International Wrestling Revolution Group. Campos trained for his professional under Black Man and Rocky Santana as well as receiving additional training by his uncle Pantera later on. He made his debut on June 11, 1997 as a "rúdo" (bad guy) character called "El Potro" ("The Colt") teaming with Bombero Infernal and Sumo Fuji against the team of Magnum Tokyo, Fantasy and Niebelina on an International Wrestling Revolution Group (IWRG) show. After wrestling as El Potro for two months he became the "enmascarado" (masked) character Mega, part of a group called "Los Megas" that would have also included Ultra Mega and Super Mega. He wrestled as Mega for about a year pairing with the original Super Mega (later Ultimo Vampiro IV), winning the hair of Judo Suwa at the final match of a ruleta de la muerte promoted in Arena Naucalpan. That match was well received by audience and lucha magazines. When he left IWRG the promotion gave the Mega character to Cesar Caballero. After leaving IWRG he worked as El Potro for a few months before reinventing himself as Último Gladiador ("the last gladiator) as he began working for the local promotion Alianza Universal De Lucha Libre (AULL) based out of "Arena Lopez Mateos Tlalnepantla" in Tlalnepantla, Morelos, Mexico. As Último Gladiador Campos incorporated ring outfits that mirrored elements of the Roman Gladiators as well as face paint. During the seven years he wrestled in AULL he won two "Lucha de Apuesta", or bet matches, against Popetikus, both times earning the right to shave Popetikus' hair off after the match. It was also during this time that his style of mixing Hardcore wrestling with high flying moves that earned him the nickname "El Máximo Idolo Suicida de Tlalnepantla" ("The Most Suicidal Idol of Tlalnepantla").
