5 Superstars whose return WWE run was more successful than their original run

#2 Brock Lesnar (2012-Present)

Lesnar became an undefeatable entity during this run.

Love him or hate him, but you sure as hell can agree that Brock Lesnar is one of the best pure athletes to have ever stepped foot in the WWE ring. On his best days, he is capable of enthralling the fans in a way that no other professional wrestler can even imagine to do. It was because his talent and his aura that he was always poised for massive things even before he made his debut for WWE.

Nicknamed the Next Big Thing, Lesnar took the world by a storm when he won the King of the Ring tournament and defeated The Rock for the Undisputed Title at Summerslam with six months of his debut. Adding glory to this, he won the Royal Rumble in 2003 and won the WWE Title in the main event of WrestleMania that year. After lengthy feuds with The Undertaker and Kurt Angle throughout 2003, Lesnar departed from WWE on a sour note after his loss to Goldberg at WrestleMania XX.

The decision to leave WWE turned out to be the best of Lesnar's career as he became the biggest star in the whole world during his time outside WWE. In his first match for NJPW, he won the IWGP World Heavyweight Title. But it wasn't until he joined UFC in 2008, where he became the UFC Heavyweight Champion, that Lesnar finally achieved the superstardom that he boasts right now.

Reappearing in WWE in 2012, Lesnar developed the new persona of The Beast, where he would decimate superstars like Triple H, CM Punk, John Cena, The Undertaker and many more. His victories over John Cena at Summerslam 2014 and Goldberg at Mania 33 gave him his fourth and fifth World Title win, with the last one being the longest of the modern era. However, the biggest achievement of Lesnar's second run was his win over The Undertaker at Mania XXX, which turned him into the undefeatable entity that he his now.
