Wolfpac were faces, Hogan joining turned them heel because nobody liked his stale ass at that time.The Wolfpac were heels when Hogan joined them, and then dissolved in February. There is no logical reason to how any of this happened, but it certainly did. Hogan and Nash turned face, crowds picked them over Goldberg, DDP legitimately turned heel for no reason whatsoever, DDP puts Hogan out of action at SS, Nash takes the title from DDP, Savage returns to take the title from Nash, Hogan beats Macho the next night, Nash immediately turns heel on Hogan, who goes back to the red and yellow. Meanwhile, Goldberg wasn't doing shyt.
Stop saying "them", the crowd chose Nash over everyone but Sting. Hogan was just standing in his spotlight.
DDP was forced to turn heel because everyone wanted to be a cool face
