4) Two-time WWE Hall of Famer Booker T
Booker T is a former six-time world champion and often contributes to WWE's Kickoff Show as an analyst. The Hall of Famer recently brought up the Tribal Chief's dominance as Universal Champion. He even alluded to a potential in-ring return to face Reigns.
Booker T is a decorated champion and was a competitor who had his fair share of great bouts. Based on being out of active in-ring competition for a few years now. Roman Reigns may be an ideal opponent for Booker due to his more methodical and story-based style in the ring.
The legendary status of Booker T gives Reigns another viable challenger for his title.
3) WWE Hall of Famer Rob Van Dam
Rob Van Dam is another Hall of Famer who has teased an in-ring return. As recently as Royal Rumble 2022, the idea was tossed around to bring the Whole Dam Show back, according to RVD. Van Dam is coming off a run with IMPACT Wrestling that ended in 2020, so he is not too far off his active days.
RVD is an interesting challenger to face Roman Reigns. His stature isn't the same as the latter's recent rivals in Brock Lesnar, Goldberg, and John Cena. But that is what makes him an intriguing choice.
RVD's versatility and unpredictability make for a unique challenge that can be compelling.
