The Doomwalker then turned his attention towards The Tribal Chief as Scarlett Bordeaux placed an hourglass in front of The Bloodline.Kross' cryptic message to Reigns, however, has meant nothing so far. The duo are yet to face off in a match and has been kept apart by the creative team. Karrion has been very vocal about facing The Tribal Chief and believes that the latter is Bruno Sammartino of the modern generation."I feel like everyone should want to be in the ring with Roman Reigns. For me, I hope nobody minds that I'm comparing him but to me, he's our modern-day Bruno [Sammartino]. What he's doing right now, in my opinion, is historic for our company's history. This art of storytelling, it's an amazing thing, and it's going very, very well. People are having fun, they're enjoying what they're watching. It's something different every week, but like, I could go on and on. That is the guy that I'd want to be in the ring with," Kross said. [H/T - Fightful]Both Karrion and Reigns are currently a part of the SmackDown roster. The Tribal Chief will defend the Undisputed WWE Universal Championship against Cody Rhodes at WrestleMania 39. The former NXT Champion, meanwhile, will be looking to win a Fatal Five-Way match next week to become the number-one contender for the Intercontinental Championship.
