Gloriosa

Elder Nyon (ニョン婆様) is the former Empress for the Kuja tribe before Hancock took over. Hancock refers to her as the former-former-former empress Gloriosa (グロリオーサ).

Personality
Elder Nyon seems to be designed on the concept of a wise old woman, as made apparent but her concerns for Amazon Lily itself and expressing knowledge her fellow Kuja did not even know. She also asks the Kuja pirates for books and has a crystal ball, both things would link further to this image. However, since she believed some of Hancock's lies about considering the World Governments terms for war this proved she was still gullible towards people's words. Although she is not immune to many of Hancock's emotional manipulation to make people follow her, Nyon can snap out of them much faster than many others, male or female.

Though not the empress of Amazon Lily anymore, she believes she can go anywhere still (which Hancock proved otherwise), but chooses to live on the outskirts of the island because of being considered a traitor. Though during their conversation about the up coming war Hancock accuses her of worrying about her own life, she simply states that she is already too old to be concerned about her own life, but expresses concern for the sake of others on the island.

She also says "Nyo" a lot.

Gorgon Sisters
Hancock, Sandersonia and Marigold were found by Elder Nyon when they escaped from their masters. Elder Nyon considers them as owing her a debt they can never repay, which Hancock promptly dismisses at every oppotunity and puts Nyon in her place.

Abilities and Powers
She is knowledgeable enough to know what a man is, unlike her fellow Kuja and identified Luffy as a man. She is also able to resist Hancock's power. While old and aged, Nyon is also apparently still strong bodied as she not only survived being thrown out of a building but landed on her feet unharmed.

Past
When she was younger, during her period ruling as the Kuja empress, Nyon left Amazon Lily and went to sea after being struck by love sickness, a thing that had many Kuja empresses before her. Somehow she managed to survive the ordeal, but the act of leaving the island did not go unnoticed.

Her own people considered her a traitor for her action, but she learned many things about the outside world, including of the opposite sex. During her journey, she happened to discover Boa Hancock and her sisters Sandersonia and Marigold, Kuja who had previously dissapeared and escaped after four years of slavery under the Tenryuubito. Seeing these girls who were her countrymen, Nyon adopted them and kept them with her until she finally returned to Amazon Lily. By the time she returned, she was given a pardon by the empress who took her place but was tainted by her abandonment. Nyon chose to live on the outskirts of the Kuja village where she would no longer bother in the affairs of the people she once ruled.

Present
When Luffy was being washed in the stream on Amazon Lily, Nyon found her fellow Kuja baffled by an apparent Body Mushroom that wouldn't come off. She revealed to the others that Luffy was a man.

Soon after Boa Hancock and the Kuja Pirates returned to their island. Upon their return, Nyon went to ask if any books had been found in their raids. Instead of a book, she was handed a newspaper. Soon afterwards, Nyon visited Hancock to warn her about the consenquences of her actions, only to be thrown out.

Later observing the fight between Luffy and the younger Boa sisters, she remained in the stadium after Hancock orders the evacuation of the arena to hide the mark on Sandersonia's back, which was only covered by Luffy. As Luffy, without hesitation, accepted Hancock's offer of returning the Amazonians who saved him over leaving the island, Elder Nyon notes how a man with such Haki of such caliber would willingly bow his head to save those who helped him. She later enters Kuja Castle to reveal the truth of both Luffy's actions on Saboady and the Boa siblings' past as a slave.
