and Japan. During his time on the independent circuit L.A. Park developed a long-running and very intense feud with El Hijo del Santo and Blue Demon Jr., interjecting himself in a storyline that played off the original rivalry between El Santo and Blue Demon creating a feud that headlined various shows all over Mexico and involves three of the most famous masks of the 1980s and 1990s. In 2004, Tapia made a number of appearances for Total Nonstop Action Wrestling (TNA), as both L.A. Park and La Parka. He wrestled in a Gauntlet for the Gold for the TNA X Division Championship at one of TNA's weekly PPVs and then appeared in yet another X Division gauntlet match at TNA's inaugural monthly PPV Victory Road, losing on both occasions. On May 7, 2005, L.A. Park debuted for Detroit's Independent Wrestling Revolution (IWR) brand Revolucha, teaming with American Kickboxer in a losing effort to El Hijo del Santo and Konnan. Park continued his rivalry with El Hijo del Santo culminating on October 29, 2005 at Revolucha 2: Dia de los Muertos in a Lucha en la Jaula match (a steel cage match). Both Park and Santo had their masks ripped apart and were bleeding profusely during the match. In February 2006, L.A. Park began a bitter feud with then IWR Champion Conrad Kennedy III (CK3). L.A. Park finally defeated CK3 on August 27, 2006 at Brawl at the Hall 6 and defended the IWR Heavyweight Championship on October 14, 2007 at Revolucha 4. After leaving CMLL in 2008 L.A. Park worked regularly for the newly started Perros del Mal Producciones, reviving his old rivalry with Perro Aguayo Jr. Working on the Perros del Mal shows also allowed Tapia to help his son make his start in the wrestling business. Originally Tapia's son wrestled as "Black Spirit" without acknowledging the relationship between L.A. Park and Black Spirit. In early 2010 Tapia officially acknowledge that Black Spirit was his son announcing that he would wrestle as El Hijo de L.A. Park ("The Son of L.A. Park") from then. In 2011, Tapia was part of Lucha Libre USA as LA Park. Xtreme Latin American Wrestling (2004, 2009–2010) L.A. Park won the Xtreme Latin American Wrestling (X-LAW) Heavyweight Championship in Friday, April 9, 2004. The bout was a decision match for the vacant title against Rey Misterio in a X-LAW show co-promoted with Baja Stars
