On July 25, 2011, CMLL released a poster for an event, which revealed that after a two-year break, Leyenda de Azul would return on July 29. While CMLL was still on bad terms with Blue Demon, Jr., the tournament was instead endorsed by his adopted brother and Blue Demon's biological son, El Hijo de Blue Demon, who also presented Mr. Niebla with the trophy after his win.
