Reigning Undisputed WWE Champion Cody Rhodes will defend his title against Solo Sikoa at SummerSlam 2024. It is heavily rumored that Roman Reigns will return to the Stamford-based promotion during or after the match.The Triple H era has featured some wild endings to major Premium Live Events. It is possible that SummerSlam also features a shocking ending due to the potential return of The Rock, who may follow Roman Reigns immediately after the former Tribal Chief shows up to confront Solo Sikoa. The Final Boss is an eight-time WWE Champion, a two-time Intercontinental Champion, and a five-time Tag Team Champion.Solo Sikoa has formed his version of The Bloodline in Roman Reigns' absence and has taken over as The Tribal Chief. When Reigns possibly shows up at The Biggest Party of The Summer to confront his former Enforcer for the latter's actions over the past few months, The Great One could attack The Big Dog and reveal that he is the real Tribal Chief.The Final Boss could then reveal that he secretly made Sikoa the acting Tribal Chief during his absence. The Rock did tell Cody Rhodes before going on a hiatus that the story between them was not over, so he may have wanted Sikoa to keep The American Nightmare in check until his return.The People's Champion could also reveal that he ordered Sikoa to make changes in The Bloodline, as Roman Reigns and Jimmy Uso lost their respective matches at WrestleMania XL and embarrassed the faction.This angle could plant the seeds for the second Bloodline Civil War at Survivor Series: WarGames, The Rock vs. Cody Rhodes, and The Rock vs. Roman Reigns in the future.Roman Reigns could add a new member to his Bloodline after rumored WWE returnSolo Sikoa has been taking shots at Roman Reigns for weeks, and he will likely get a response from his cousin at WWE SummerSlam next month. The rivalry between Reigns and Sikoa will probably lead to another Bloodline Civil War.Meanwhile, the Stamford-based promotion has reportedly signed Tama Tonga's brother, Hikuleo. The 33-year-old may decide to join forces with Reigns after his potential debut. It could be followed by The Usos reuniting with their Tribal Chief.If The Rock also returns to run the new Bloodline, WWE could add Sami Zayn to Roman Reigns' Bloodline to set up a five-on-five WarGames match between the two sides at Survivor Series 2024.
