Overview
Main characters
Star Butterfly
Princess Star Butterfly is thought to be a magical princess from the dimension of Mewni. On her 14th birthday, she is given the family heirloom - the royal magic wand - but after she causes a big accident, she is sent to the Earth dimension as a foreign exchange student. She then lives with the Diaz family. She enjoys exploring and being away from her parents and their pressure to make her into a perfect princess.Nefcy had originally designed Star as a fourth-grader obsessed with Sailor Moon and wanting to become a magical girl despite not having any powers. The design was initially just her with heart cheeks, and the devil horns came later. By the time she pitched the idea to Disney, she had made the character older, and an executive suggested she would have actual magical powers, leading to the current foreign exchange student concept. Nefcy says Star is very much like her and that she has a lot of flaws and aspects of being a real girl. Star is Eden Sher's first voice acting role. Sher describes Star as Disney's first-ever butt-kicking princess and identifies with her a lot: "She's always wrong. She's always messing up. But at the same time, this character has such a good heart. Star is fiercely loyal when it comes to her friends and never backs down from a fight. There's so much going on there. And that's what makes this character so much fun to voice."
Disney sitcom actress Olivia Holt dressed up as Star during the live-action promotions of the series weeks before its Disney XD premiere. Star wears a sea green dress with a pink octopus on the front and magenta and orange striped leggings as well as purple boots with a rhino design. She also has a small yellow Star shaped bag with a face on it and wears a magenta devil horn headband on her head. Star has long blonde hair that goes down to her knees.
Marco Diaz
Marco Ubaldo Diaz is Star's best human friend, later becoming her boyfriend. Prior to meeting Star, he was known as a safe kid. He is of mixed Caucasian and Hispanic descent, and typically wears a red hoodie, having said that he owns a dozen of them. He helps Star during their fights against the villains using mostly martial arts moves from training in a karate dojo. He's had a crush on classmate Jackie Lynn Thomas since kindergarten; in "Bon Bon the Birthday Clown", they start dating, but end their relationship later on in "Sophomore Slump".In "St. Olga's Reform School for Wayward Princesses," he dresses up as a princess in order to retrieve Pony Head, but ends up starting a women's rights movement, of which he is known as Princess Marco Turdina. His success results in him getting regular royalty checks of 650 dollars, the cash being used as a running gag in multiple episodes in Season 2. In "Running with Scissors", Marco psychologically ages 16 years in Hekapoo's time-dilated dimension, wherein two years pass for every minute on Earth. Subsequently, in the season 3 episode "Marco Jr.", it was confirmed that both Marco himself and his friends and family view him as being "26 to 35" years old. As his "Turdina" persona, he has developed a love for makeup.
Nefcy originally conceived of Marco to be a child obsessed with Dragon Ball Z and karate. After Star's character was changed to be a foreign exchange student, she felt Marco's character needed to balance out Star's, so he became more of a straight man yet is still quirky. Some of Marco's character was based on Nefcy's husband. She likes that McArthur portrays him away from being nerdy or unlikeable and that Marco is smart and thoughtful. McArthur said that he felt really connected to the character, as he has a martial arts background, and when he was younger he had two best friends that were girls.
Supporting characters
Moon Butterfly
Queen Moon Butterfly and Katie Driver ) was the Queen of Mewni and Star Butterfly's mother. As a teenager, she succeeded to the throne and leadership of the Magic High Commission when Toffee killed her mother, Comet Butterfly, during his attack on Mewni. She made a deal with Eclipsa to learn dark magic, but used it to sever Toffee's finger instead upon realizing that the price of its use was too high. Her experience made her overprotective of Star at times while ruling with a calm, steady, and thoughtful hand. Moon is shown to be a resourceful and capable fighter in her own right, with powerful magical abilities, experienced horsemanship, keen senses and extensive knowledge of the geography and history of Mewni.After eventually learning that she and Star are of Pie Folk descent and accidentally wounded by Eclipsa when forced to harm Meteora, Moon ends up in the magic dimension and loses her memories. Despite Star's attempt to save her, she retains her amnesia upon being sent back to Mewni by the dimension's guardian, Firstborn. Moon returned to Mewni as Pie Folk, who then exploited her amnesia to bake their pies before Star saves her mother. Moon regained her memories shortly after and ultimately decided to live in the forest, due to her mistrust of Eclipsa, with River and the other Mewmen who had lost their homes under Eclipsa's rule. It is later revealed that Moon ordered Rhombulus to free Globgor and created Mina's army of Solarian warriors to take back the crown. While Mina intends them to exterminate all "monsters", including Eclipsa and her supporters, Moon wishes merely to take the throne and send Eclipsa, Globgor and Meteora into exile. She later regrets it when Mina rebels against her in order to carry out her own plan.
