When a superstar captures every active title, they become a Grand Slam Champion. This occurs by winning either the Raw (formerly WWE) or SmackDown Tag Team Title, the Intercontinental Title, the United States Title, and either the WWE or Universal Title.
At WrestleMania 35, fans were treated to a dream becoming a reality as Kofi Kingston left with the WWE Championship. As a result, he became the 20th overall Grand Slam Champion in WWE history and the 13th under the current format; which started in 2000.
