following day in a rematch. On August 12 Hunico and Epico lost the FCW Florida Tag Team Championship to Johnny Curtis and Derrick Bateman in a three-way match, which also involved the team of Donny Marlow and Brodus Clay. On July 26, 2011, Hunico wrestled in a dark match at the NXT tapings, losing to Justin Gabriel. Main roster debut and unmasking (2011–2013) On the August 12 episode of SmackDown, Arriaga made his WWE debut, taking over the role of Sin Cara from Luis Urive, the former CMLL Místico, who was serving a 30-day suspension for violating WWE's wellness program, and defeated Tyson Kidd. Arriaga reprised his role of Sin Cara the following week, taking part in a battle royal to determine the #1 contender to the World Heavyweight Championship, from which he was the last man eliminated by the winner, Mark Henry. On August 20, Urive took back the role of Sin Cara for a live event. At the following tapings of SmackDown, Arriaga once again appeared under the mask. On the August 30 episode of SmackDown, Sin Cara defeated Daniel Bryan and attacked Bryan after the match, turning heel for the first time. At the tapings of the September 16 episode of SmackDown, the original Sin Cara made his return, confronting Arriaga's impostor version of the character. On the September 19 episode of Raw, the impostor Sin Cara attacked the original character prior to his match with Cody Rhodes, but was forced to flee after a brief brawl. On the September 23 episode of SmackDown, the impostor Sin Cara attacked the original version during his match with Daniel Bryan, took his place in the match and pinned Bryan for the win. The following week, he revealed a new black attire to distinguish himself from the original version, while also explaining that he was going to steal the Sin Cara identity from Urive, just as Urive had stolen the Místico identity from him six years prior. At Hell in a Cell, the impostor Sin Cara, now being referred to as "Sin Cara Negro", was defeated by the original Sin Cara, now referred to as "Sin Cara Azul". The feud continued on the following SmackDown with Negro attacking Azul. The rivalry culminated at the October 16 taping of SmackDown in Mexico City in a Mask vs. Mask match, where Sin Cara Azul was victorious, unmasking Arriaga after the match. On
