#4 Rey Mysterio
Who is that jumping out the sky? Yes, it is Rey Mysterio and he is confirmed to be in the Royal Rumble match. As of late, the masked legend has been in a feud with Andrade over the United States championship.
It looks like both of them have concluded their feud this coming Monday on RAW in a ladder match. The Lucha legend could be in his last Royal Rumble match simply due to his age and injury history.
It has been rumored over the last month that Rey Mysterio may call it a day after WrestleMania and finally hang up his boots. If this is the last time we ever see the former World Champion we will always remember the 2006 Royal Rumble where he dedicated his victory and eventual title win to his friend and rival, the late Eddie Guerrero.
While his son may begin competing and Mysterio would likely sign a WWE Legends deal with the company, it will be odd to not see the Master of the 619 wrestling anymore.
