#3 Seth Rollins (with Jon Moxley)

Both Seth Rollins and Jon Moxley (fka Dean Ambrose) achieved fame early on in their WWE main roster run while being a part of The Shield. By the time 2018 was coming to an end, tensions began forming among The Shield members.
On an episode of RAW, Jon Moxley walked away from his friends after the trio lost a match to Braun Strowman, Dolph Ziggler, and Drew McIntyre. Soon after, Roman Reigns went on a hiatus to battle leukemia. On the same night, Rollins and Ambrose defeated McIntyre and Ziggler to become the RAW Tag Team titles. Ambrose had other plans though, and he turned on Rollins following the victory.

Rollins soon lost a Handicap match to AOP, thus losing the belts. Ambrose went on to leave WWE and signed a contract with AEW. He appeared at the promotion's first event, Double Or Nothing, in May 2019. Currently, Rollins is one of the biggest heels in WWE. Ambrose, on the other hand, is doing quite well for himself in AEW and is currently holding the coveted AEW World title.
