During the Ultimate War against Alien Empera, Ultrawoman Marie was a member of Silver Cross Aid, a medical group formed during the war. During Ultraman Ken and Ultraman Belial's confrontation against Alien Empera, Marie gave Ken the Ultimate Sword, which helped him unleash his hidden power and repel Empera by injuring him.

During Belial's Rebellion, Mother of Ultra was seen helping the other Ultras and young Zoffy. She was attacked by Belial, so Ken tried to save her, but was also defeated. However, King Ultraman arrived and sealed Belial in the Space Prison, ending the conflict.

Marie and Ken eventually married, becoming known as Ultra Mother and Ultra Father, respectively, as members of the Intergalactic Defense Force. He later rose through the ranks and became the leader of the Silver Cross Auxiliary. Marie later adopted Ultraman Ace, the son of her husband's deceased friend, and raised a biological son named Taro.

Once, young Taro was scolded by Ultra Father for wanting to be like him. Marie comforted the crying child, telling him that Ken didn't want him to be like his father, but rather wanted him to be his own person who could one day surpass him.
