Princess Star Butterfly is the main protagonist of Star vs. the Forces of Evil. She is a teenage princess of the Kingdom of Mewnifrom another dimension sent to Earth by her royal parents after an altercation with a couple of monsters. She currently lives with her Earthly hosts, the Diaz family. She is voiced by Eden Sher.
Star is at a medium height. She has long blonde hair down to her knees, and posh pearl pink hearts as cheeks. She wears a red hairband with devil horns and a sea green dress with a white collar, white lace on the sleeves and bottom, and a cute light purple squid design on the front. She also wears pink and orange stockings, dark magenta boots with a rhino design, and a little yellow star-shaped side bag with a face.
Star is energetic and friendly. She loves having fun, and she usually has an optimistic outlook on life. Also, she loves to help others. Whenever she sees that someone is upset, she does her best to cheer them up. She is a bit reckless, as she enjoys fighting monsters and doing wild things. Strangers, in her eyes, are just friends she hasn't met yet, and she feels bad if she hurts someone's feelings, whether intentionally or not. Star Butterfly has a happy-go-lucky attitude and always puts smiles on everyone's faces.
