or storylines while others were simply paired up for the tournament. For the Torneo Nacional de Parejas Increíbles tournaments, CMLL often teamed up a técnico (those that portray the "good guys" in wrestling, also known as faces) and a rudo (the "bad guy" or heels) who are involved in a pre-existing storyline feud at the time of the tournament so that the tournament itself can be used as a storytelling device to help tell the story of escalating confrontations between two feuding wrestlers. The tournament format followed CMLL's traditional tournament formats, with two qualifying blocks of eight teams that competed during the first and second week of the tournament and a final match between the two block winners.

Atlantis teamed with Euforia to win the 2014 tournament. While some of the teams were put together because of ongoing storylines others were teamed up based on previous feuds.
