Mistress Death
From Multiversal Omnipedia
Mistress Death is the female (and primary) personification of the death-principle, and sister to Eternity. She rules silently (in general) over her realm of the dead, and is neutral and impassive in most affairs. Mistress Death's most significant acquaintance was the Titanian Thanos, who loved her and sought to be her mate for quite some time.
The one occasion where Death took a proactive role was during the Contest of Champions, when the Grandmaster attempted to contest with her for the soul of the Collector.
