#2. The Stinger never entered the Royal Rumble
Royal Rumble never saw The Icon competing against 29 other men. In his brief WWE tenure, Sting has contested only four matches.
After years of eluding Vince McMohan, Sting's in-ring career in WWE finally began after the 2015 Rumble and ended before the 2016 edition. Thus, there was no chance he could enter the event.
Corey Graves deleted his Tweet! More details HERE.
Though he is still competing as a wrestler in AEW, it is debatable if he would rejoin WWE to compete in the Battle Royale.
#1. Scott Hall/Razor Ramon has never competed in the 30-man match
It is undoubtedly a shocker that Scott Hall has never competed in the 30-man battle royale. He had two different stints in WWE as Razor Ramon and Scott Hall. However, he never participated in the Rumble match under either gimmick.
He, however, has participated in the show four times, each time in a title match. Though his ally Kevin Nash returned for a Rumble appearance in 2011, Hall is yet to make an appearance. Considering his age and retirement, he may not do so in the future.
