This week's edition of WWE RAW not only featured John Cena's last appearance on the red brand, but it also saw the return of two top superstars, Brock Lesnar and Roman Reigns, as the final members of both teams for the Men's WarGames Match. However, it seems a betrayal angle might unfold at the upcoming premium live event.Team Vision was scheduled to face off against CM Punk's squad in the main event of WWE RAW. However, instead of the planned face-off, the event erupted into a chaotic brawl among the superstars. Things didn't stop there, as The Beast Incarnate made a shocking return and attacked CM Punk.While fans were still processing the surprise, Roman Reigns' music hit as he walked down to the ring. He then took down Brock Lesnar, much to Paul Heyman's surprise. That said, in a massive turn of events, the 60-year-old Hall of Famer might backstab Bron Breakker and Bronson Reed at Survivor Series and choose Lesnar's side over The Vision.Many believe the storyline is for The Beast Incarnate to take the place of Seth Rollins as the leader of the heel faction. However, WWE might decide to pull a swerve on fans by having The Oracle betray The Vision at the upcoming annual event and reunite with Lesnar as his right-hand man.The Beast Incarnate is a major merchandise draw for the company and doesn't need to be part of a group to reclaim his place at the top of the men's division. If this happens, it could lead to Breakker and Reed turning face as part of a blockbuster storyline.However, this angle is speculative at this point, and viewers are eagerly waiting to see what the creative team has in store for them in San Diego.WWE could book a Triple Threat Match for the World Heavyweight Championship at WrestleMania 42If the above scenario plays out, Brock Lesnar might enter into a compelling program with CM Punk on WWE RAW. They could then blow the roof off with their feud to set the stage for a stellar match at WrestleMania 42 for the World Heavyweight Championship.Interestingly, since Roman Reigns likely has an interest in dethroning Punk, in a jaw-dropping twist, he might feature in the potential rivalry between the World Heavyweight Champion and The Beast Incarnate.If this happens, their rivalry could garner a lot of fans' interest, potentially setting the stage for a Triple Threat Match at 'Mania for the world title. However, this angle is also speculative.
