LADY STYX.

Summarized Overview
To Lady Styx, the teeming sprawl of life and the trillions pulses of souls is disruptive; a structural flaw in the fabric of existence that must be corrected.
The Guardians of Oa achieved a victory that was less a triumph and more an accidental reprieve. When the Oan ritual finally took hold, it did not break her—it turned her inward. She was banished, yes, but never defeated.
In order to build new flesh, Styx transfused her essence into the unformed, fetal body of La Dama. As a result, the entity was revived; trapped within the confines of a mortal body.
Calculating her reemergence, Lady Styx persists as an insidious, shadow lurking within La Dama's mind; a curse that plaques her with horrific visions and nightmares.

Manifestations of the Void (Abilities)
Virogenesis & Necromancy: Her touch initiates the Stygomorph process; necrotic spores that remain dormant, waiting for the host's death to trigger a grotesque rebirth.
Insanity & Telepathy: To hear her whisper, is to realize that the idea of "self" is a lie. In her presence, the victim’s identity is dissolved, lost within her perfect, singular will.
Reality & Matter Manipulation: Universal laws do not apply to Lady Styx. She unmakes them, shifting reality into strange angles the human eye was never meant to perceive.
Possession & Ensoulment: Lady Styx hallows out the soul of the host from within, turning the body into a living tomb where she calculates her next reemergence.
Energy Drainage & Immortality She is an entropic law made manifest. She is not "alive" in any biological sense that the Guardians can measure.
