#1 Cody Rhodes
When talking about stars who have gone to do better outside of the WWE, then it impossible not to talk about Cody Rhodes.
The former Intercontinental and tag-team champion has become one of the biggest stars on the indie circuit since his departure from the company in 2016, and his co-produced All In event has to go down as a landmark event for indie wrestling in the US.
Cody has had exceptional matches all over the world since he left the WWE, and has shown that there is a life for wrestlers outside of the McMahon empire.
Rhodes has shown an acute business sense and an incredible knowledge of the industry since leaving the WWE and has made himself into one of the biggest must-see acts in wrestling. His work in the likes of NJPW and ROH has been nothing short of outstanding and given his current level of success, it seems unlikely that he will be returning to a WWE ring anytime soon.
