Passage: On August 21, 2001 Virus participated in his first major CMLL tournament, the Torneo Gran Alternativa ("Great Alternative Tournament") where he was teamed up with Blue Panther. In the first round they defeated the team of Alan Stone and Mr. Niebla but lost to Olímpico and Sicodelico Jr., who would go on to win the entire tournament. After having been a Rudo (a Heel, or bad guy) his entire career Virus was turned Tecnico (Face or good guy) in 2002. In 2003 he took part in a series of matches between CMLL tecnicos, himself, Ricky Marvin and Volador, Jr., and a group called "the Havana Brothers" based out of southern California that consisted of Rocky Romero, Ricky Reyes and T.J. Perkins). The well received series of matches between the six led CMLL to create the CMLL World Super Lightweight Championship. Rocky Romero became the first champion but lost the title to Virus on November 14, 2003. Virus held the title for 392 days before losing it back to Rocky Romero. In 2005 Virus was turned Rudo once more and generally used to help young, high-flying tecnicos get more experience. Over the summer of 2006 Virus represented CMLL in All Japan Pro Wrestling's Junior Heavyweight League tournament. He ended up winning only one match, defeating MAZADA but lost to Katsuhiko Nakajima and Katsushi Takemura, failing to advance in the tournament. On October 2, 2007 Virus won CMLL's recurring Reyes del Aire ("Kings of the Air") tournament outlasting 11 other competitors in a torneo cibernetico, lastly eliminating Valiente to win the match.
