- Cody Rhodes - He had a significant run in WWE before leaving and later became one of the key figures in AEW.
- Brandi Rhodes - Cody's wife, who also had a wrestling career in WWE.
- Kenny Omega - While primarily associated with New Japan Pro-Wrestling and AEW, he had a brief stint in WWE's developmental territory.
- Chris Jericho - A veteran of both companies, Jericho has had an extensive and storied career in WWE.
