The original Bloodline was created in 2021. The original members were Roman Reigns, his manager Paul Heyman, and the Usos Jey, and Jimmy. Roman Reigns used the Usos to help him retain the WWE Universal championship. As the years past Roman won the WWE championship, so Roman Reigns needed more members to do his biting's.
Sami Zayn, also known as the Honorary Uce joinned the Bloodline May 27, 2022. Sami is called the Honorary Uce because he isn’t actually related to them. September 3rd, 2022 Solo Sikoa joined the Bloodline. That version of the Bloodline seemed unstoppable, and they were until April 7th, 2024.
On April 7th Roman lost the WWE Undisputed Universal championship to the American Nightmare Cody Rhodes at WrestleMania 40, on night 2. April 7th was the day the original Bloodline officially ended. A little bit beforehand Jey Uso, and Sami Zayn left, but After April 7th there wasn’t a Bloodline until November 2024
Solo kicked out Paul Heyman, and Jimmy Uso, and formed his own Bloodline. The new Bloodline members were Tama Tonga, Tonga Loa, and Jacob Fatu. Roman Reigns eventually reformed his Bloodline Jey Jimmy, Sami, Paul, and of course himself, when it came time to fight the new Bloodline in WarGames November 30th, 2024. The original Bloodline had to get CM Punk to team with them so they weren’t outnumbered, because the new Bloodline got Big Bronson Reed to team with them.
In 2024 Cody Rhodes won the Royal Rumble a second time to face Roman Reigns for the WWE Undisputed Universal championship. On the February 2nd adtion of Smackdown it seemed that Cody Rhodes gave his spot to the Rock to face his cousin Roman Reigns, for the title. Since nobody liked that they ended up changing things a bit. Since in real life Dwayne Johnson A.K.A. The Rock is a member of TKO the company that now owns the UFC, and the WWE, they made The Rock be a corporate bad guy. At WrestleMania 40 night 1 The Rock teamed with Roman Reigns to fight the American Nightmare Cody Rhodes, and Seth Freaken Rollins to decide if the match between Cody and Roman will be Bloodline Rules, or not. Bloodline Rules is basically a no rules match. The Rock A.K.A. The Final Boss has not made it clear if he is offcialy a member of any Bloodline team, and as of April 7th, 2025, when I am writing this The Final Boss has some kind of partnership with John Cena.
