#4. Shawn Michaels and two others have appeared in 12 Royal Rumbles
Shawn Michaels is one of the greatest of all time and has won Royal Rumble twice. During his illustrious WWE career, he entered the match on 12 different occasions. His last entrance was in 2010. Michaels faced The Undertaker at WM 26 and was forced to retire after losing to The Deadman.
The Heartbreak Kid is one of only eight people to win multiple Rumbles, with his last win being in 1996. He was the runner-up twice, finishing second in both 1994 and 2007.
In addition to Michaels, both Big Show and Rey Mysterio have also competed in 12 Rumbles. The Big Show last competed in 2017 but never won. He was runner-up in both 2000 and 2004.
On the flip side of being huge, Rey Mysterio has also appeared in 12 Rumbles. He competed last year and won in 2006. Since he's the only active member of these three, he will add another appearance to his resume this year.
