#4 Major surprises, debuts, and returns
Surprises, debuts, and returns are the best part of a Royal Rumble PPV. After all, who can forget AJ Styles' brilliant arrival at the 2016 edition of Royal Rumble? In 2018, WWE made a blunder in this department.
Rey Mysterio and The Hurricane were the only significant returns. Having Dolph Ziggler come in at number 30 enraged many fans. The number 30s have been disappointing for the past few years, especially in 2017. Roman Reigns was booed out of the building when he made a "surprise" appearance as number 30.
Reportedly, WWE has something unique and surprising for this year's Royal Rumble. WWE is focused on not spoiling it. What if Kenny Omega signed for WWE and made an appearance at the 2019 edition of Royal Rumble? The possibilities are limitless, and we are hoping WWE won't mess up this time.
