In 1980 Peña decided to change wrestling personas, giving the Espectro Jr. outfit and name to his cousin Jose Elías Pinceno, who has wrestled as Espectro Jr. since then. Instead of working as Espectro Jr., Peña came up with a totally original character of his own called Kahoz (sometimes spelled Kahos or Khaoz), a sinister masked "rudo" character who invoked various dark spirits as part of his pre-match ritual. Many have likened the Kahoz character to one of Lucha Libre original showmen, Murciélago Velázquez. Kahoz would often carry a bag of live pigeons to the ring with him, releasing them at his opponent and then making it seem like he ripped the head of one of the pigeons and smeared the fake blood all over himself or his opponent. To Peña the Kahoz character was not about winning championships, but about the psychology of the character and actually scaring the audience, so while he did not win any titles as Kahoz it was considered a huge success and he main evented shows all over Mexico. While Peña had the mind for wrestling his body could not handle the heavy main event schedule that he wrestled as Kahoz and by 1985 he gave up the gimmick to work as "Espectro de Ultratumba" ("The Ghost from Beyond the grave"), giving the Kahoz gimmick to Astro Rey instead. Astro Rey's Kahoz was nowhere nearly as important nor as successful as Peña as Astro Rey lacked the charisma and theatrics of the original. Peña only worked as Espectro de Ultratumba for a short period of time, giving the gimmick to his cousin in 1986. Peña tried working as "Dalia Negra" but his body could not take the strain, forcing Peña to retire in 1986. Peña would briefly wrestle as "the Rose" in 1994 but only worked a handful of matches. Peña's final match at the 2001 "Guerra de Titans" where he wrestled, and lost to Cibernético. Peña had been active backstage for years before his retirement, always offering suggestions of wrestling gimmicks, storylines and booking, so when he retired Peña was hired by Empresa Mexicana de Lucha Libre (EMLL), Mexico's oldest professional wrestling promotion, to work in their public relations department. Over the next couple of years Peña began booking shows for EMLL and started writing storylines for the company.
