Death Curse is the keeper of the Second Demon Gate in Ultimate Ghosts 'n Goblins.
Death Curse flies in circles around Arthur as it attacks with electricity. Its weak point is the head, which has two horns sticking out, a large gaping mouth, and a single giant eye. Its body is made of something like the waves of a magnetic field that grows in the dark. While in this form, it will send lightnings to destroy platforms and make Arthur fall in the pit. From time to time it temporarily takes an invincible shadow form and starts spinning around at high speed and unleashes electric spheres.
Later in the Black Palace, Arthur must face either Death Curse or Arthror again, depending of the path he takes.
