#4. Shinsuke Nakamura - Debuted for WWE at NXT TakeOver: Dallas
Shinsuke Nakamura's WWE signing got nearly as much hype as AJ Styles' did. WWE's decision to sign Shinsuke Nakamura was largely considered the greatest international signing the company had ever made.
Shinsuke Nakamura would be assigned to the NXT brand, where he was instantly recognized and loved by the more hardcore fanbase. His WWE debut would be at NXT TakeOver: Dallas in April 2016 - which was incidentally Sami Zayn's final appearance for the NXT brand.

Shinsuke Nakamura's debut match in WWE is largely considered his best in nearly five years. He found success on the NXT brand in his year-long tenure there, becoming the first two-time NXT Champion.
While his success didn't translate as instantly on the WWE main roster, he has some impressive accolades, including a Royal Rumble win, a WWE Title match at WrestleMania, reigns with the United States Championship, Intercontinental Championship, and the SmackDown Tag Team Championship.
In many WWE fans' eyes, Shinsuke Nakamura didn't live up to his full potential, but the reality is that he was already past his prime when he signed with the company in 2016.
