Lady Death
The cosmos and a large number of other cosmic entities were born at the same moment as Lady Death. She doesn't actually exist, yet she can take on a physical shape to interact with things that do. She frequently appears as a person or human skeleton in Marvel comics and hardly ever talks because she typically gets her point through just by being there. She resides in the Realm of Death, which also houses the Infinity Well, a source of infinite knowledge.
She is capable of releasing a soul from its body, but she often hands it off to other spirits who symbolize the afterlife. If she decides to overlook a being, they either become immortal or, if they possess the necessary knowledge and prevail in a battle against Death, they earn immunity to actual life loss.
She wields the Power Cosmic, which allows her to control any aspect of the Marvel world, including matter, space, time, energy, reality, and magic. She typically opts not to utilize her power, though. She assumes the guise of a mortal's beloved and comforts them as they pass away.
Death is seen as a Multiversal menace, yet she actually presents no genuine harm to the cosmos because her only purpose is to make sure that most living things die. There is no genuine method to vanquish Lady Death because she is only a notion and hence fundamentally invincible. The Death of Death, a component of the Living Tribunal that decides if copies of her in various realities are required, is the only being capable of slaying one of the most potent gods in the Marvel world.
