Death Fire and Death Fire King are enemies in Castlevania III: Dracula's Curse. Instead of attacking directly, they enter the bodies of creatures long dead and infuse them with new life, taking control over their actions.
These spirits seem to be related to common ghosts, possibly occupying a higher rank and hence one of them being referred to as "King".
Death Fire appears at the end of the Haunted Ship of Fools, where it awaits floating over an altar until the player arrives. It then enters two nearby caskets to take possession of the bodies inside: two Mummies and a Cyclops. Once these monster have been defeated, the entity is expelled from them and shatters into small pieces.
A stronger version called the Death Fire King appears at the end of either the Morbid Mountains or the Rampart and Lookout Tower, depending on the route taken by the player. It attacks in the same way, with the addition of possessing one last powerful creature: Leviathan.
- These enemies are not actually mentioned in the Dracula's Curse bestiary. Their names were taken from the Tokuma Shoten Akumajō Densetsu guide and should not be considered official.
