Mariemaia Khushrenada is the daughter of Treize Khushrenada, the Duke of OZ and Leia Barton, daughter of Dekim Barton and sister of Trowa Barton. She grew up to be the leader of the Barton Foundation and the supposed head of a new world order.
Mariemaia was born to her parents and was supposed to have died young, but was groomed by her grandfather, Dekim Barton, who's used Mariemaia by making his granddaughter think that she is following the will of her father: Treize Khushrenada, the Duke of Oz. If Operation Meteor went as planned, the young girl would be ruler of Earth, as stated by her uncle, though, in fact, she would be a puppet ruler. But with The Gundam Pilots' betrayal, the conquest had to wait until the Earth thought of peace.
Mariemaia kidnapped Vice-Foreign Minister Relena Darlian, so there would be no opposition to the Barton family's rule over the Earth. The occupation of Earth was quick with no resistance and victory seemed assured, when a number of insurgents, including the Gundam pilots tried to stand up. Mariemaia felt that their efforts would soon be exhausted, until the populace stands up and Wing Zero destroys the shelter. Dekim urges her to take up her rightful place as ruler of Earth, but Relena slaps sense into her, literally, as Relena reasons with her about her true purposes and responsibilities in her life. When Dekim tries to kill Relena with his pistol, Mariemaia interposes herself between the two, and takes the bullet for Relena (thus saving her life), as she's become mortally wounded, much to Relena's shock and surprise. Dekim then gets executed by one of his subordinates for his own high treason. Lady Une soon has her rushed to medical attention. Soon afterwards she makes a full recovery, and is adopted by and placed in Une's custody.
Mariemaia is often thought to be a naive girl whose intentions are to follow 'her father's wishes' though she is clearly being used as a tool to represent the Barton Family. She is used because her youth would prolong the Barton hold over Earth. Dekim seems to see her as a tool than his own blood. Mariemaia seems to have strong intentions to follow the will of her father to prove that she has a connection with him though she is an illegitimate child and hasn't known him for very long. Her relationship with her late mother is unknown as Leia was not mentioned much in the whole series by Mariemaia but given a picture that her uncle once showed to to Trowa, it was presumably an affectionate one. Furthermore, since Leia died just two years after Mariemaia was born, it could be that she simply doesn't remember anything of significance about her mother because she was so young at the time.
- Mariemaia is based on Mineva Lao Zabi.
- At the end of Mobile Suit Gundam Wing: Endless Waltz, Mariemaia is shown in a wheelchair with Lady Une visiting her father's grave.
