#1 Booker T
WWE Hall of Famer Booker T returned to the ring recently, to wrestle in his own promotion, Reality of Wrestling. The former WWE commentator has time and again spoken of his desire to tag with his brother Stevie Ray in WWE. He openly challenged The Revival, and even told WWE to add him to the men's Royal Rumble earlier this year.
Booker T is still in tremendous shape and by the looks of it, can still wrestle a match in WWE (see for yourself in the video below!)
The 54-year-old has mostly been a commentator or panellist on WWE PPVs, while also being an analyst on WWE FOX's Backstage show. Super ShowDown could very well be the place where Booker T returns, perhaps bringing along his brother, to challenge a tag team in WWE.
His last match in WWE was way back in 2012.
Alternatively, Booker T could be a part of commentary at the PPV, alongside the likes of Corey Graves, Michael Cole, and Jerry The King Lawler.
