Zrala Xetafena Maitolia (alias Sara Catarina Clipper) is an alien from the planet Sixam. She is a former citizen of the Sixamian Grand Empire and student of the Sixamian Imperial Academy for Space Exploration. She became stranded on Earth alongside fellow alien and friend Xandria Kliper after engine failure aboard their spacecraft caused them to crash, resulting in the tragic loss of all hands besides Zrala and Xandria. They decided to live amongst the Sims rather than hide for six months waiting for rescue. Fortunately for them, they had brought disguises in order to better conceal themselves from Simlish society. When Xandria chose the identity of Alexandria Clipper, Zrala adopted the alias of Sara Clipper, choosing to have the same last name as Xandria in order for them to pose as twin sisters.
Zrala is one of the two main characters of Diary of a Young Alien.
