Emeraldas is independent and strives to be in charge of her own life without being tied down to anyone or anything. She has a terrifying reputation as a professional killer and is feared by many. Emeraldas however only kills those who are cruel and unjust, believing in a personal code of conduct, much like her friend Captain Harlock. However, in spite of all of this, she is very lonely as she cannot find anyone to stay with her for various reasons including her wish to continue journeying through the sea of stars. Emeraldas however has a lot of pride in herself including her flaws, as shown when she keeps the scar on her face as a reminder to herself to not take her vulnerabilities for granted. Because of this, she refuses to get a Machine Body at every chance she had; although partly it was so that she would not end up like her mother and the intense hate she has for the Machine Empire. Even when bedridden and near death, Emeraldas would rather have an android command her ship than live forever as a soulless machine. She is interested in people who dream especially when hope seems impossible for them. As a La Metalian, Emeraldas is assumed to have a long lifespan that can last at least a millennium. Emeraldas has been well known as a powerful combatant, especially with the sword function of the Gravity Saber, with very few people able to best her. Her aggressive style was well known amongst her many opponents. Even after she contracted a disease that may kill her, her prowess is enough to defeat some of the best in a duel. In addition, she is an excellent shot, both with Gravity Saber's rifle function that she rarely uses as well as her Cosmo Dragoon, using a quick draw technique that is able to kill an opponent instantly. Emeraldas with help with her ship's computer is an excellent navigator. (Source: Toki No Wa Wiki)
