#1 Shawn Michaels
Shawn Michaels is the first ever Grand Slam Champion in the WWE. The Heartbreak Kid has achieved several outstanding accomplishments in his career. He has delivered some of the greatest matches in the history of professional wrestling and the WWE Universe is forever indebted to him for that.
Shawn Michaels is a former three times WWF World Heavyweight Champion, and a former World Heavyweight Champion as well. He also won the Intercontinental Championship, European Championship, and the Tag Team titles. HBK is also one of the few wrestlers to win the Royal Rumble match more than once in his career.
Michaels was inducted in the WWE Hall of Fame Ceremony in 2011 and is getting re-inducted this year as a part of DX. There will be many more Grand Slam Champions in the WWE, but none can ever match the charisma and aura that Shawn Michaels possessed.
