A Nightmare on Elm Street/WMG

Freddy has split personalities

 * Think about it! He was born to a Nun mother and conceived from a psychotic father! A recipe for a spilt personality! And with the kind of life he led, the violent personality started taking over. And soon it had all but consumed him! But the nice personality sometimes shines through like the time in the 7th one where he was telling his daughter how much he loved her and her mother/his wife. But his violent side takes over soon! So he isn't a Complete Monster, just the personality is!

In the 'verse of New Nightmare, Movie!Freddy managed to get a hold of a magic ticket to cross over.

 * For one thing, Wes Craven could have lying to Heather in order cover his own ass for allowing such a thing to happen (after all he created the character).
