#5 Brock Lesnar (2000s, 2010s, 2020s)
Brock Lesnar, just like Shelton Benjamin, walked into the company in 2000 under a developmental contract. He was assigned to Ohio Valley Wrestling where he first met Paul Heyman. Along with former college roommate Benjamin, Lesnar started his career as a tag team wrestler and was seen as a breakout star.
He later joined forces with Heyman, who managed him from his debut on the night after WrestleMania x-8 in 2002 until Heyman left him and joined Big Show in November of that year. Heyman's original hype man style helped him reach the heights where he is today, especially with the duo back together since Brock's WWE return in 2012.

Lesnar became the WWE Champion within his first 5 months on the main roster, and held the championship on 4 different occasions before his untimely departure from the company only 2 years after his debut on RAW. Even though the Superstar left the company to try his hands at different sports, he ended up returning to his roots and benefiting more than any other Superstar.
One of Lesnar’s biggest achievements came in 2014 when he broke The Undertaker’s 21-match WrestleMania undefeated streak at WrestleMania XXX.
The Mayor of Suplex City has never won a mid-card title in his entire career, nor has he ever scored a Tag Team Championship while on the main roster. However, he is a 3-time Universal Champion and a 5-time WWE Champion. Lesnar will be walking into the new decade as a member of the RAW brand and the current WWE Champion.
