Kingston is one of the highly talented Superstars in the WWE roster right now. He is the only Superstar on this list along with Zack Ryder, who needs to win a World Championship to complete a Grand Slam in the WWE.

1) WWE Intercontinental Championship (4 times)
2) The United States Championship (3 times)

Kofi Kingston is currently a part of the highly successful stable "The New Day" alongside Xavier Woods and Big E.
He is mostly involved in the tag team championship picture and it is unlikely that he will receive a main event push anytime soon. He will have to settle for some more tag team or possibly some mid-card singles Championships.
