This is one wrestler that even some CHIKARA fans are surprised to learn wrestled in their favourite promotion. The current Sin Cara, once known as Hunico in WWE, is actually a decoarated former CHIKARA star. Before he signed with WWE, Hunico wrestled under a mask as Incognito and debuted at the 2007 Torneo Ciberneticoas part of a team of masked wrestlers. While that team lost to the Kings of Wrestling, Hunico would go on to be incredibly successful for the promotion, especially for someone who wasn't a regular member of the roster. He teamed with Lince Dorado and El Pantera to form Los Luchadores de Mexico(The Wrestlers From Mexico) and they would go on to win the 2008 King of Trios tournament, making him one of two WWE stars to hold that distinction. That same year, Hunico defeated Helios in the finals of the Rey de Voladores tournament (King of High Fliers), again an honour only one other WWE superstar currently holds. https://www.youtube.com/watch?v=HiGi4VdSsPY#t=116
