#2. Brock Lesnar's Return in 2012
How Brock Lesnar ruined another wrestler's career - Watch Now!
Brock Lesnar returned to WWE on April 2, 2012, on Raw, as a heel, by confronting and delivering an F-5 to John Cena which set up the feud between the two. It was his second run with the company and WWE wanted to establish him as a brutal maniac who would basically kill his opponent to win a match and they achieved it in his match against John Cena at Extreme Rules 2012 when he almost murdered him. He lost the match, but he was dominating for the most part of it. Since then, he has been in and out of the company due to his part-time status. But whenever he returns, we know that we are in for a madcap feud.
He even ended the famous streak of The Undertaker that was described by Sports Illustrated as being "the most shocking result since the Montreal Screwjob" and established himself as the face of the company. In this stint apart from ending the streak, Lesnar won the WWE World Heavyweight Championship, Universal Championship and had some of the most unforgettable feuds with John Cena, The Undertaker, Triple H, Roman Reigns and Randy Orton. He even became the longest reigning WWE Champion with 504 days. Now, he is one of the moat popular stars in the world from the current roster.
