Nu Gui

Nu Gui is the daughter of the first Emperor of China, and one secondary antagonists in mexican cartoon, Las Leyendas. She discovered a magic flower whose essence granted her immortality, but also drove her mad. She then poisoned her father and went on to become a powerful witch.

Mocks Baba Yaga for being Quetzalcoatl's servant and attempts to sacrifice Marcella for her own benefit, only to end up a servant herself in the final episode and forced to rely on Marcella to save her.

She is voiced by Sofía Niño de Rivera in original language and Paula Barros in english-dub.

Description
Despite being an evil witch, and part of Baba Yaga's coven, Nu Gui has been portrayed more sympathetically than her "sister", being focused on her "noble goal" which happens to be freeing her fellow witches from Quetzalcoatl's clutches, and not much else. In the Season 1 finale, Nu Gui, forced to aid Quetzalcoatl in Baba Yaga's place, gives Leo the Celestial Point (which fell off of him without him noticing and temporarily wound up in the hands of an elite Horroroso) and begs him to fulfill his part of the prophecy and free her kind.

History
According to her origin, her father; The Emperor Of China, desired immortality and was initially proud that her daughter found it (in the form of a flower emitting a special steam, from which she made a potion), seeing it as "The greatest gift a father could have". What Nu Gui didn't tell her father however was that the flower's immortality was a gift only for the first person who discovered it. For everyone else (like the Emperor for prime example), there was only madness and death. Ambitious even at a young age, Nu Gui killed her father.

For Episode 9 Nu Gui makes a flat-faced attempt to convince Marcella that she's not about to become the sacrifice needed to awaken the Terracotta Army and she's not buying it. As mentioned above, Episode ends with Baba Yaga's hand bursting out of the rubble following her fight with Nu Gui. The season finale reveals that Nu Gui survived as well.

Quetzalcoatl offs her pretty quick after she tries to help the protagonists. Instantly incinerating her with his Eye Beams.
