Sarabi was married to Mufasa and was Queen Consort of the Pride Lands.
One morning, she gave birth to their son Simba, who was next in line for the throne. When she was informed by Scar of Mufasa's and Simba's deaths months later, she was devastated as Scar took the throne.
During Scar's Reign, Sarabi was the only one to constantly refuse orders and try to talk sense into Scar, suggesting to leave Pride Rock. Sarabi was overjoyed when her son returned fully grown and defeated Scar, thereby assuming his rightful place as King of Pride Rock.
Soon after, Nala becomes Simba's bride, and took Sarabi's place as the Queen of the Pride Lands, and she became the grandmother of Simba and Nala's cubs, Kiara and Kion.
