He is an evil and monstrous counterpart of my Pal Casper, who has a Shadow Black ghostly transparency, and with completely red eyes without pupils, as well as large fangs in place of teeth. He Also Sounds Like a Demon when he Speaks. The Only way to Defeat him is Using the Weaponized Concept of Light, Primarily Through Flashlights or Spotlights which Repels him. Despite Wilmer being the Main Villain, Nightmare Casper is Even More Dangerous than Him.
