10 WWE Superstars who should return at SmackDown 1000

#6 Rey Mysterio

Before Rey Mysterio made his WWE debut, he'd had a legendary career in WCW, but the grim brand ended up adding an entirely new chapter into it. When he came to SmackDown in 2002, the new expansion was in full swing and that he wasted no time in creating an impression about the WWE Universe.

Mysterio quickly rose into the very top, getting among SmackDown's most well-known wrestlers since he turned into a multi-time tag team champion with the likes of RVD, Eddie Guerrero, and Batista. But in 2006, he won the Royal Rumble game before heading on to WrestleMania 22 and winning the World Heavyweight Championship -- solidifying him as a main event player.

Though he'd be drafted back and on during his later years in the organization, there is no denying that Mysterio's greatest career moments happened on SmackDown. Therefore, he must make his presence felt about the upcoming 1000th incident and also be thinking about he made a surprise appearance in this year's Royal Rumble, a return for' Mr. 619' is not all that improbable.
