Vampire (Nintendo 64)

Vampires are boss characters and regular enemies in Castlevania 64 and Legacy of Darkness. Their special attack is the ability to grab and bite the player characters inducing the status ailment, "Vamp", in which the character loses the ability to use secondary weapons, and if it isn't purified fast enough, the player will ultimately join the ranks of the Undead, becoming a vampire in Dracula's forces (and Game Over). This status can only be cured with Purifying Crystals.
