Lady Death (Marvel)

Lady Death, sometimes referred to simply as Death, is a Marvel comics super-being and personification of death: although she is seldom seen and rarely speaks she has been known to manipulate and interfere with mortals on a few occassions: amongst her would-be-lovers are Thanos and Walker - to Thanos she "mothered" the anomaly known as Rot and the two teamed up to destroy this offspring before it could devour the universe.

Although often content to keep a balance between life and death she is shown as more than happy to take advantage of situations so as to get the upper-hand: Lady Death is also known to empower most death-gods and demons, allowing them to take souls that have died though the exact nature of their dealing is unknown.

Lady Death is technically without gender but prefers to take the form of a female skeleton dressed in robes - though s/he has appeared in other forms, such as when Death faced Dracula as a male warrior when his creations of vampires was seen as a threat to Death's own power.
