Charlotte Fregula

Charlotte Fregula, or Echidna, is a legendary Archenemy from Greek mythology.

Appearance
Charlotte has the upper body of a beautiful woman with long hair and ample breasts and the lower body of an enormous snake. Her hair and scales are the colour of dried grass or milk tea, and glitter with the colours of the rainbow. She wears a thin cloth wrapped around her waist and several golden ornaments.

Personality
Charlotte has a twisted love for her children. She felt sorrow over their deaths and loathes the gods and heroes who killed them, to the point that she plots to attack the gods themselves. However, she also ranked her children in a hierarchy, considering the like of Hydra "adorable" while dismissing others like Orthrus. She doesn't care for humanity or her fellow Archenemies, to the point that she plans to trigger the Calamity (which would wipe them out) to have the opportunity to attack the gods.

Background
According to legend, Charlotte would expose her humanoid upper half from her cave to lure in men and ate them once they were within range. She also mated with many inhuman monsters to give birth to Archenemies more powerful and violent than herself, such as the Cerberus and Hydra. In truth, she did not physically give birth to her children, instead using her power to create a biology lab that she then used to create her children.
