Was Freddy Krueger Burned?

His skin is scarred and burned as a result of being burned alive by the parents of Springwood, and he has no hair at all on his head as it presumably all burned off. In the original film, only Freddy's face was burned, while the scars have spread to the rest of his body from the second film onwards.

Why did Freddy get burned?

According to the original film, it was because someone didn't sign the search warrant in the appropriate place. The parents of the children tracked him down and found him in the boiler room where he took his victims. The parents poured gas into the room and set him on fire, which caused his melted-like facial features.

Was Freddy Krueger a child molestor in the original?

In the original script, Freddy was a child molester.

According to IMDb, the villain was changed to a child killer because producers wanted to avoid comparisons to a story in California about a series of child molestations at the time of filming.
