1. Goldberg (2000)
When it comes to using Goldberg properly, WCW had a very simple formula; but like so many other things during their final few years of existence, the company managed to screw it up. The formula was this: Goldberg came to the ring with one of the coolest entrances of all time, and destroyed opponents in three or four minutes, polishing them off with a vicious spear and then his awesome finisher, the jackhammer. WCW followed this formula to a tee 173 times, to great success. Then oddly, they strayed, and decided Kevin Nash pinning Goldberg after getting assistance from a taser-wielding Scott Hall was the proper way to go. Spoilers: it wasn't. At The Great American Bash in June of 2000, WCW decided to stray even further from this formula and make Goldberg a heel. This raised the extremely difficult question of "How do you make someone who doesn't talk and cleanly defeats opponent after opponent in mere seconds a heel?" The answer to that question was "You Can't." WCW tried to turn Goldberg face a couple of months later, but by that time the company was on its last legs and soon went out of business. Let Goldberg be a (very obvious) lesson to all future wrestling promoters: if you have a popular, undefeated babyface, keep him winning until the money runs dry. Certainly, don't have him lose AND THEN turn heel.
