“Agatha: Coven of Chaos” added Aubrey Plaza to its roster, and people are speculating that she may be playing one of the most powerful characters in Marvel Comics.

This is just a rumor, but Giant Freakin Robot reports that the actress will portray Death — the personification of the concept of death. Plaza did tell GQ she had a “pivotal role.”

The Marvel Cinematic Universe has recently explored other cosmic beings, with Eternity in “Thor: Love and Thunder,” so Death would be a good continuation of that trend.

Death is one of the most powerful cosmic beings in Marvel Comics. While she's often seen as the enemy of life, she functions as a silent observer and maintains the cosmic balance.

Death is the twin of Eternity and exists alongside other powerful entities, such as Lord Chaos and Master Order. She is most associated with Thanos since he fell in love with her.

She owns every lost soul and has the ability to bring a being back to life. She appears to those about to die, often taking the form of a loved one or a soothing appearance.

Assuming the rumors are true, it will be interesting to see how Death factors into “Agatha: Coven of Chaos” and if Marvel will somehow bring back Thanos.
