Character(s): Sage Solara, Vega, Leona, Tessa, Gemma, and Adora
From: Star Darlings
Representation: Indian (Sage), Asian (Vega), Black (Leona, Tessa, Gemma, and Adora)
Their Importance: Star Darlings was a rather obscure and short-lasting Disney franchise starting as a book series before becoming a web cartoon. It focused on Sage Solara, Leona, Libby Rose, Vega, Scarlet Maroon, Cassie, Piper Dream Soule, Astra Torch, Clover Molensa, Tessa, Gemma, and Adora, 12 teenage girls from the planet Starland, and their missions to grant wishes on Earth. Most people don't notice, but many of them are POC. Sage, who is the main character (at least in the cartoon), is Indian (as revealed in one of the books, her mom is named Indira), which is very rare, as even other POC main characters are usually from other places. Sage is bright and hopeful, always looking forward to spreading as much good luck and granting as many wishes as possible. Leona is an aspiring pop star and the lead singer of her own band. Vega is practical and tends to think about things before doing them, and is revealed to be Asian from her Earth disguise. Tessa is an aspiring cook, and her younger sister Gemma is a supportive sister with dreams of also being a great wish granter. Adora is a combination of a nerd and girly girl, being into both science and fashion.
Issues: While in the books, each girl gets an equal time to shine, the cartoon only focuses on Sage, Leona, and Vega (as well as Scarlet and Libby) while all the other girls, including S=Tessa, Gemma, and Adora, are practically left behind except for them getting one 2 minute short each and the finale episode. They don't even get real focus in the pilot.
