When Brock first entered the WWE (WWF at that time) he came in as a heel. The transition was remarkable and it reflected the success as to how Brock was packaged. His walk into facedom took an unexpected turn, a match with the Rock the biggest face in the company and the passing of the torch from the Great One to the Next Big Thing.
As funny as the Rock was and is, at that time his character had begun to get stale and slowly the fans turned on him and began to chant for Brock at every turn. This was in big part to Paul Heyman in the way he marketed Brock on screen and Brock himself. It was Brocks workrate that helped "get him over" with the fans and it helped to slowly transition his character from heel to face. In this promo we see how Heyman worked with Brock and how much of a monster Brock was protrayed as.

This finally culminated in the match for the WWE championship against the Rock. Although Rock was the face in this match he started to get booed and Brock the heel was getting cheers. This accelerated Brocks change from Heel to face and helped him become a profitable commodity to the WWE/WWF. The next post I will look at what changed and what happened to Brock that transitioned him from fan favorite to hated wrestler. I'll give you a hint Goldberg.
