Medusa Queen

'' She is the first Medusa in existence, the mother of every snake in Egypt and one of the Seven Great Beasts in Africa. Due to her status as the first Medusa she can both take on a human appearance and one of the traditional medusa (half-snake lower body). ''

The only exception is Apas due to her extremely pure blood lineage. She is listed as a contender for one of the 4 Gods of the Dark Plane: The Evil Sacred God. Mo Fan theorized that the Medusa Queen is possibly on the same level as Khufu (one of the Gods of the Dark Plane).

Biography
Records state that she was the first human Curse Mage, but during her time, the Curse Element was not accepted by the public yet. People claimed that the Curse Mages would bring misfortunes upon them, so they offered Medusa to the Primordial God of Snakes, Nehebkau an Emperor Level existence. To their surprise, Nehebkau did not kill Medusa, but mated with her instead, giving birth to the Medusae that are stronger than the snake demons and are capable of using some of her curse magic. The Medusae treated Medusa as their leader, and the Primordial God of Snakes became her subordinate instead who was later absorbed by her inside her body, Truly transforming her into Half Snake Half Human Medusa Goddess form. Medusa has a strong hatred of humans, and it combined with her ancient Curse Magic, granting her the scariest eyes in the world, it is known as the strongest Psychic Power, the Medusa’s Stare.

Lineage
Every high-level female snake has inherited the Medusa’s eyes. Their vengeful stare possesses Medusa’s great power. They also posses additional powers and attributes depending on how pure their lineage is:

Apas
For not being mixed with any other demon creature unlike her sisters, she is the only descendant able to fully shift into a human appearance like the Medusa Queen and her eyes are said to be as strong as her mother or even stronger than her.
