Princess Star Butterfly is the main protagonist of the Disney Channel and Disney XD's [2] animated series Star vs. the Forces of Evil.


Star Butterfly is an intergalactic princess from the Kingdom of Mewni, who has been sent to Earth by her parents to live a normal life, after many years of fighting evil in space. While on Earth, she lives with the Diaz family, and takes Marco Diaz on adventures in other dimensions, and in battles with monsters.


Star is extremely energetic and friendly. She loves having fun, and she usually has an optimistic outlook on life. She loves to help others and 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. She is also stubborn at times, as she often does things her own way and not listening to other people's rules or even take advice. Strangers, in her eyes, are just friends she has not met yet, and she feels bad if she hurts someone's feelings, whether intentionally or not. However, Star can be egocentric, wanting attention and getting frustrated with things that bother her. Thus, she gets jealous very easily. Star has a happy-go-lucky attitude and always puts a smile on everyone's faces. She also works very hard towards her goals, so much that she will sometimes go sleep-deprived.

Physical Appearance

Star is a fair-skinned fourteen-year-old girl with light blue eyes and long blonde hair that goes down to her knees. Her cheeks have posh pink hearts, which sometimes change into things that reflect her emotions, such as hourglasses when she is bored, grey skulls when she is pumped for battle, white skulls when she is depressed, or light bulbs when she has an idea.

During her Mewberty period, Star had purple hearts appear all over her skin, until she eventually turned completely purple and aquired an insect-like appearance. Her hair turned pale lavender twisted into two buns, her eyes were replaced with glowing hearts, and gained four extra arms and butterfly-like wings. After her mewberty phase, she reverted back to normal, but left with a small pair of wings on her back, often hidden by her hair.

Role in the Series

Season One

Star's adventures start off on her fourteenth birthday, where her Mother bestows upon her their family's greatest heirloom, the Royal Magic Wand. Unfortunately due to being reckless and irresponsible, she causes so much chaos and destruction that her parents decide to send away. At first she thought her parents were sending her to St. Olga's Reform School for Wayward Princesses, but to her relief they were sending her to Earth, where she can learn her magic safely. Star was dropped off at her new school in a place called Echo Creek, where she met Marco Diaz, a student at her school and would be living with during her stay on Earth. During their first meeting, Star immediately took a liking to Marco and declared him a friend, but Marco at the time was not so keen about her because of how chaotic she was, especially with her magic. Marco finally lost it when Star accidentally sucked his room into a black hole, that he decided to run away from home, abhorrent of his new roommate. Feeling sorry, Star found Marco outside a shop, and acknowledged the hardship she had put him through. She was planning to find another family to live with, but after a brief battle with Ludo and his monster army, Marco expressed a change of heart toward Star, and a preference for her to remain a resident of his home.

Through the course of the first season, Star and Marco go on many adventures, and Star tries her hardest to adjust to life on Earth which for her proves difficult. She even misunderstands many things during her time on Earth, such as thinking Echo Creek Academy's football team was going into a fight to the death with a rival team called the "Warriors" or mistaking a product known as the "Banagic" as an actual magical object. A few times, Star is encountered by Ludo and his monster army who are out to steal her wand, but never succeed. She also tried to help Marco with some of his personal problems. It would not be until the near end of season one where Star would meet her most greatest enemy of all, Toffee.

When Marco was kidnapped by Toffee, Star set out to rescue him, accompanied by Ludo and Buff Frog. Apparently Toffee was proven to be far too smart for Star that she was forced to surrender her wand to him, only to learn that he wanted her to destroy it. Using a whispering spell, her wand destroyed itself and blew up Ludo's castle along with Toffee and Ludo's former monster army. However, a new tiny unicorn came along to recharge the wand, giving it a new appearance, with half of the star face missing.

Season Two

Star continued to live with the Diazs, practicing her magic under the tutorials of Glossaryck and handling school life. Star remains reckless and irresponsible, but over the course of the season develops more maturity. Star even struggled with her newly restored wand. Even though it remained reliable, it had not been the same since the day it was destroyed. It was now powered by a unicorn corrupted by an evil force, and did not work properly when Star feels negative emotions.

Star's friendship with Marco slowly became very strained, especially when he started dating his long time crush, Jackie-Lynn Thomas. In the episode "Sleepover", a game box called Truth or Punishment revealed that Star had a crush on Marco just as it got crushed by a dump truck. Throughout the second half of season two, Star struggled with her growing feelings for Marco, and tried her hardest to ignore them. Marco would not know about Star's crush on him until "Face the Music", when the songstrel, Ruberiot, wrote a song about Star for her Song Day. His song revealed all of Star's deepest and darkest secrets, including her crush on Marco. After that, Star and Marco's friendship became even more strained and the two of them desperately tried to avoid each other. During an end of the school year party, in "Starcrushed", Marco asked Star straight out if she had a crush on him, and answered no. She just wanted the two of them to be friends, to which Marco agreed with. However, after Star's mother showed up in her room to take her back to Mewni and with news that Toffee had returned, Star confessed to Marco in front of everyone that she does have a crush on him before tearfully leaving Earth.


The Disney Wiki has a collection of images and media related to Star Butterfly.


  • In earlier conceptual versions of the series, Star was originally a grade schooler who did not have magic powers, but believed she did. After some suggestions on making Star older and have real magic powers, Daron changed her into a princess from a different dimension.
  • Star Butterfly's character was influenced by many Anime heroines that Daron Nefcy admired, such as the female leads of Sailor Moon, Magic Knight Rayearth and Revolutionary Girl Utena.[1]
  • Daron Nefcy originally wanted Star to be a fourth grader but executives wanted the character to be a little bit older.[1]
  • In "Cheer Up Star", she is revealed to have coulrophobia (a fear of clowns).
    • Star is the first Disney Heroine to have coulrophobia, with the second being Riley Andersen.
    • But she appears to not be afraid of clowns anymore as she participated in a ritual with Janna to see Bon Bon the birthday clown.
  • In "Diaz Family Vacation", it is revealed that she inherits her passion to fight monsters from her father, who secretly fights monsters himself.
  • In "Royal Pain", Star implies that she and other people from Mewni are not humans when she tells her father "Humans put things in there and flush them down." when he inquired about the toilet.
    • This could also explain in "Mewberty" when she went through her metamorphosis and why she has butterfly wings as of now.
  • She later states in the episode "Mewnipendance Day" that she is a "Mewman", humans who live on Mewni.
  • She dressed up as Ludo for Halloween in "Hungry Larry".
  • Most of the time Star's bangs overlap her eyes and eyebrows, possibly due to how large her eyes are drawn.
