Belinda Zee, also known as Superior Girl, is a Bizarro clone of Kara Zor-El, aka Supergirl. She is the opposite of every way, and hence, just as Kara wants people to like her, Belinda wants everyone to hate Kara. Despite this, she is part of Kara's social circle, and interacts with her and Lena Luthor. In the final issues of Supergirl: Cosmic Adventures in the 8th Grade, Belinda, encouraged by the school principal, embraces her villanous nature, becoming Superior Girl. In this guise, she attacks Supergirl.
