Nightmare Freddy is cold-hearted and malicious; a warped, twisted version of the original Freddy's persona. Like the other nightmares, Nightmare Freddy has no qualms about tormenting his victims with his metallic hands and enjoys mocking them when given the opportunity, as seen in Ultimate Custom Night. As with other nightmares, his put-downs tend to be rather sardonic in nature. He speaks using a low-pitched, monotonous, gravelly, robotic voice. He is also somewhat poetic in his speech. The Freddles however, are shown to be more mischievous and shy, in contrast to their master-of-sorts.
