#4 Cody Rhodes

There's no doubt that Cody had already proven himself in WWE as a solid performer. He was a reliable mid-carder but somehow after a while, WWE couldn't figure out what to do with him which led to the introduction of the "Stardust" gimmick. It almost became evident that Cody would never be given that main event push and he'll never climb the ladder to be the face of the company.
Realising that, Cody left the organization only to go to rebuild himself as a main eventer first in indies and then with NJPW that WWE has since made multiple offers to Cody only to get declined again and again. Ever since Cody has left WWE, he has grown immensely in terms of popularity and gained well-deserved respect from all quarters. The biggest regret for WWE? Cody is the face of its most recent competition in the form of All Elite Wrestling (AEW).
