#3 Samoa Joe

Like Bobby Roode, Samoa Joe was another Superstar who became a huge name in the pro wrestling industry after joining TNA in 2005. He was a Grand Slam and Triple Crown champion in TNA, and after a decade of wrestling for them, he joined NXT in 2015.
But Joe, too, was a part of the WWE, having been in WWE's developmental territory Ultimate Pro Wrestling, where he had feuds with a certain John Cena.

Joe, unlike Roode, had just one appearance on WWE television, on Jakked, where he faced Essa Rios. Following that appearance, he wrestled in ROH, TNA, and Pro Wrestling Noah, to name a few.
After returning to WWE, Joe won the NXT Championship twice, and is the current United States Champion, and is considered by many as one of the best heels in the business, currently.
