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.
She was born to her parents but was suppose to have died young but was groomed by her grandfather, Dekim Barton, who 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 (Though a mere tool to rule the Earth himself.), as said by her uncle. But with The Gundam Pilot's betrayal, the conquest had to wait until the Earth thought of peace.
