The former Sin Cara will now be going by Cinta de Oro. He recently changed his Twitter username to signify the change.
The man who previously used the name Cinta de Oro passed away in 2016. He was one of Sin Cara's idols and coaches growing up. The original Cinta de Oro’s sons gave Sin Cara permission to carry on the legacy of the name and gave him the last mask worn by their father.

WWE currently owns the "Sin Cara" trademark. Cinta de Oro was the second man to use the gimmick after Caristico left the company. The two men feuded over the gimmick in 2011 and Cinta took full ownership of it in 2013.
Sin Cara was released by WWE on Dec. 8, roughly a month after he went public with his release request. On Dec. 14, he showed up at AAA Guerra de Titanes to help out Pagano as he was being attacked by Killer Kross.
