#3 Brock Lesnar
Brock Lesnar was a name that many in the wrestling world were familiar with and when he returned in 2012, the world was shocked. Brock Lesnar was definitely a much bigger star in 2012 than he was in the year 2004, when he departed, primarily because of his stint in the world of UFC.
Lesnar proved, by hanging with some of the best in the world of MMA, that he was a legitimate fighter and this was an aspect that was used by WWE to book him in some memorable feuds across the duration of the entire decade. But Lesnar was also part of arguably the most newsworthy headline from the decade- ending The Undertaker's undefeated streak at WrestleMania.
I know that a lot of WWE fans will be up in arms when they see Brock Lesnar mentioned in this list, ahead of names like AJ Styles and Becky Lynch. But the fact of the matter is that Brock Lesnar has always been in a prominent spot, through the course of the decade and almost always in the title picture as well.
His feud with Goldberg was pretty memorable too! Whatever Brock Lesnar has done has always made the news and how!
