Mynoghra

Mynoghra, previously known as "Cleopatra," is Nyarlathotep's second-in-command in the Army of Chaos. She is an antagonist in Seeds of Evil.

Physical Appearance
As of the modern day, Mynoghra has a striking resemblance to the Egyptian queen Cleopatra, who in actuality is the same individual.

Personality
Due to having experienced death twice (the first time by Lightsen, the other by Tsukuyomi, though the latter was hesitant due to being in love with her), Mynoghra is seen to be emotionless, even fearless.

Superhuman Strength
Mynoghra is almost as strong as Scathach, being able to topple entire armies and lifting objects of nigh-infinite weight and mass.

Superhuman Durability
Mynoghra is able to withstand very powerful forces, such as impacts, crushing weights, high pressure, concussions, and so on.

Immense Beauty
Mynoghra is inhumanly beautiful, being able to charm even the moon god Tsukuyomi. She retains her current form in order to allure victims only for Nyarlathotep to enslave them later.

Shapeshifting
Mynoghra has the ability to shapeshift like her cousin, but due to having inhuman beauty, she chooses not to.

Cleopatra and Tsukuyomi
During the early age of humans, Mynoghra assumed the persona of the Egyptian queen Cleopatra, and ruled the country with a benevolent heart. When the gods arrived to bring the "human" queen gifts, Tsukuyomi, Amaterasu's brother, fell in love with her. When he challenged Cleopatra to a swordfight, the latter had proven her swordsmanship to be superior. They start a relationship, which was forbidden in the Law of the Gods. Years later, Cleopatra becomes pregnant with Tsukuyomi's child. Having caught wind of the news from space, Nyarlathotep sets a course for Earth with the intent of retrieving his cousin. Simultaneously, the gods ambush and capture Cleopatra and sentenced her to death for fraternizing with a god. Tsukuyomi, as punishment, was forced to execute his lover, killing her and their unborn child, leaving him with severe psychological trauma.

Trivia
