Answer: In the beginning he is just Robert Englund, but as the film goes on, the characters start becoming who they were in Nightmare 1, so he begins to become Freddy, and goes away so he doesn't harm anyone. The demon that looks like Freddy isn't Freddy, just a demon who takes the shape of the character Freddy.
