After the huge success of the Attitude Era, the WWE found itself in position similar to that of the early 90s. With the Rock leaving for Hollywood and Austin taking his ball, it was time for a new crop of talent to take centre stage. During this time, new faces such as Batista, John Cena and Randy Orton each made the step up from developmental, while seasoned pros such as Eddie Guerrero, JBL and Chris Benoit also were given their chance to shine. But of all these stars, there was one man whose rise took the world by storm; the NCAA Division 1 Champion, and all-round freak of human nature, Brock Lesnar Many may cite Cena or Vince McMahon as the architect of the phrase ruthless aggression, but it was Lesnar who truly personified those words. https://www.youtube.com/watch?v=MTc2dkF98Ls Having debuted the night after WrestleMania X-8, the behemoth destroyed all those who faced him, and was crowned WWE Champion after defeating the Rock just five months after his first TV appearance. A further two world titles arrived, but most significantly it was the quality of his feuds that really caught the eye. His programme with Kurt Angle remains one of the greatest in pro wrestling history, and his Hell in a Cell clash with the Undertaker was another absolute classic. While those two opponents were other huge stars of the Ruthless Aggression era, nobody defined that generation quite like the beast incarnate, Brock Lesnar.
