7 times Rey Mysterio was a real-life superhero

#4 The Joker (WrestleMania 25)

Mysterio channels a darker side, dressing as the iconic Batman villain.

Sometimes, to defeat a monster, you must become a monster. And that was clear when Rey took on one of WWE's most villainous men, John 'Bradshaw' Layfield at WrestleMania 25.

In a tribute to the late Heath Ledger, who had died months prior, Mysterio channeled his dark side, dressing as iconic supervillain the Joker, who Ledger played in 2008's 'The Dark Knight'.

With the mad clown's signature Purple and Green aesthetic, Mysterio completed the look with a chalk-white mask and red 'scars'.

It must've helped, as Mysterio defeated the Texan Billionaire in less than 30 seconds, claiming the Intercontinental Championship, with JBL quitting WWE shortly afterward.
