Nightmarification Process

Were you looking for the original process?

The Nightmarification Process is Springtrap's modified version of the original Nightmare Initiative. Just like the original, it turns animatronics into Nightmare forms.. BUT, Their aggression levels are also increased to 255, and their greater cognitive thinking is hindered using Slaving Protocols that keep their AI at no greater than 5. If they have a pre-existing power, such as the ability to SAVE, their AI is in a fixed state at unknown levels. It would be obvious that Transcendence enhances their AI as well.

The new Nightmare Machine actually uses a substance called Nightmare Fuel. Considering what it's made out of, it is very unlikely that the original Nightmare Initiative used this fuel.
