The original Sin Cara is wrestling for the AAA wrestling promotion in Mexico while the WWE is still using the Sin Cara gimmick with a different wrestler in the WWE. According to PWInsider.com on Feb. 25, Sin Cara said the WWE is threatening to sue AAA but he is fighting them.
If this was just about Sin Cara wrestling the gimmick in AAA in Mexico, it would be one thing but AAA will be shown on the El Rey Network in the United States starting this year.
Sin Cara made his debut in AAA for the television taping last week but remained a dark shadowy figure instead of the full fledged Sin Cara character. When asked, he said the WWE's legal threats was why he did so.
The problem here is that Sin Cara claims he owns the look and gimmick of Sin Cara, not the WWE. He said the WWE just gave him the new name but when it comes to the character, he owns all rights to it. The WWE disagrees and continues to use the gimmick with Hunico under the mask.
The two will end up in a legal battle because Sin Cara said he won't back down and will be able to use the gimmick in full by May. The reason it will take three months is unknown. Maybe there is a chance the WWE unmasks their Sin Cara by that time and the original agreed to hold off on using the gimmick until then.
