5 wrestlers you didn't know participated in the Royal Rumble match

#1 Mil Mascaras (1997)

The legendary luchador Mil Mascaras competed in one Royal Rumble match...

In 1997, the WWE was in a talent agreement with Lucha Libre AAA World Wide (or simply known as AAA), and for that particular year's Royal Rumble, one of the greatest luchadors of all-time entered the Rumble 11th in Mil Mascaras.

To the WWE fans, they will know Mil as the uncle of former WWE Champion Alberto Del Rio. They may also remember Mil as a part of the 2012 class of the WWE Hall Of Fame.

In the 1997 Rumble, Mil would eliminate two superstars and last for over seven minutes before eliminating himself by diving over the top rope onto AAA rival Pierroth, Jr.
