The King of Fighters/Nightmare Fuel


 * If Magaki's highly unsettling "true form" doesn't give you nightmares, the way he fights will.
 * Duo Lon's idle pose involves him holding his leading foot in such an extreme twisted inward angle that it suggests that his ankles are broken or at very least he can easily dislocate them at will.
 * Literally in the case of Geese. He has an alternate form called Nightmare Geese that will give you nightmares trying to fight him. In this form he's one of the cheapest SNK Bosses in existence. Subverted in Maximum Impact 2 where he's balanced, but then doubly subverted in 2002UM, which introduces an even cheaper version of Nightmare Geese that you have to fight as the last Expert challenge in Challenge Mode to unlock everything.
