#3 & #2. AEW Stars The Young Bucks
Before they found success in AEW, The Young Bucks (Matt and Nick Jackson) made an appearance on WWE TV nearly 13 years ago.
In August 2008, The Young Bucks appeared on The Miz and Morrison's Dirt Sheet show on ECW. Miz and Morrison made Matt and Nick dress up as D-Generation X before beating them up in the ring.
The Young Bucks did not go on to have a career in WWE. However, they found much success elsewhere. They won several championships on the independent circuit before joining AEW in 2019.
In addition to being in-ring competitors, the Jackson brothers are also AEW's executive vice presidents.
A few months ago, The Young Bucks joined forces with Kenny Omega and The Good Brothers to become part of The Elite.
The Young Bucks recently defended their Tag Team Titles in a steel cage match against The Lucha Brothers at All Out. The Jacksons suffered defeat to lose their championships.
