"Dracula" isn't a unique monster type but a powerful example of a vampire, an undead humanoid with pale skin, red eyes, and feral features who gained his curse after death, as found in the D&D 5e SRD. Players can find a stat block for this legendary figure in the D&D 5e SRD which details his ability to polymorph into a bat, wolf, or mist and has resistances to nonmagical damage unless it's from the sun, alongside skills like spider climb and the ability to enter a home uninvited.
