Star Butterfly

Princess Star Butterfly is the main and titular protagonist of Star vs. the Forces of Evil series.

Star is a teenage princess of the Kingdom of Mewni (located in another dimension) sent to Earth by her parents in order to learn how to use the royal magic wand. In seasons 1-2, she lives with her earthly hosts, the Diaz family.

Appearance
Star is a fifteen-year-old girl with a height of 5' 2". She has fair skin, light blue eyes and long blonde hair that goes down to her knees. Most of the time Star's bangs overlap her eyes and eyebrows, possibly due to how large her eyes are drawn.

Her cheeks normally have posh pearl pink hearts on them. The heart marks on her cheeks sometimes change into other things to reflect her emotions, such as hourglasses when she is bored, grey skulls when she is pumped for battle white skulls when she is depressed, light bulbs when she has an idea, stop signs when in danger, or broken hearts when heartbroken. Considering that her mother's cheeks have magenta diamond-shaped marks and other queens of Mewni have borne similar marks, it is logical that this is a genetic trait.

When going through mewberty, purple hearts appear on Star's skin (including her forehead and ears), although she is able to peel them off. Eventually, she turns completely purple and acquires an insect-like appearance. Her hair turns pale lavender and is twisted into two buns. Her eyes are replaced with glowing hearts, and she gains four extra arms and large purple butterfly-like wings. At the end of her mewberty phase, she reverts back to normal but with a small pair of "mewberty wings".

In her second mewberty form, Star's eyes become yellow four-pointed stars, her skin becomes a lighter shade, and she gains an extra two pairs of arms like before along with large fiery gold wings. Her hair also appears as a lighter shade of blonde in two long bun braids. After she gains full control over the form, her eyes appear as their regular blue, and she doesn't glow.

Star's wardrobe consists of every color of the rainbow. She usually wears a red or magenta hairband with devil horns and lets her hair down, but she sometimes uses her magic wand to change into other hairstyles like pigtails or ponytails (and on one occasion, to change her hairband into other kinds of headgear).

While Star has many different outfits, she mainly wears five recurring outfits:
 * A sea green short sleeved dress with a white collar, white lace on the sleeves and skirt and a cute pink octopus on the front. She also wears pink and orange leggings, dark magenta boots with a rhino design, and a little yellow star-shaped side bag with a face.
 * A teal sleeveless dress with four colorful stripes on the chest, white lace on the bottom, and a white bear face on the left side towards the bottom. She also wears pale light sea green and white stripped leggings, pink boots with white bunny faces and dark pink bottoms, and a silver bracelet with spikes.
 * A sky blue sleeveless short dress with a tied string at the neckline. Around the waist, the dress has a peach-colored belt and a red belt that is slanted towards the right. She also wears a little gray cloud-shaped bag with a face, striped blue leggings that are dark blue at the top and become lighter with each lower stripe, light blue sneakers with white tips, and fuzzy light blue leg warmers.
 * A dark green-blue dress with a mint green trim, with pink striped leggings, a spider necklace, and white boots with yellow stars on the heels, hot pink bottoms, and pale pink tips. Her devil horns headband is magenta instead of red.
 * A turquoise sleeveless dress with frilly light-blue shoulders, purple belt, puffy white trim, and a picture of a narwhal on the bottom left side, blue and purple striped leggings, grayish plum boots with pink tips with faces on them and dark blue soles, a magenta headband, and a silver spiked bracelet on her left wrist. Shares similarities with Star's other recurring dresses.

Personality
Star is very energetic and friendly. She loves having fun and 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. 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. Star has a happy-go-lucky attitude and always tries to put a smile on everyone's faces. She also works very hard towards her goals, so much so that she will sometimes end up greatly sleep-deprived, as shown in "Monster Arm".

Owing to her rather sheltered upbringing, Star's optimism and enthusiasm can border on recklessness, to the point of endangering the people around her with her madcap antics. She has rather simplistic views on concepts such as leadership and responsibility, believing that prioritizing fun above all else matters the most. All this, coupled with her lack of understanding of Earth customs, often puts her and Marco in strange, dangerous situations. While rarely ever angry, she does express annoyance towards people who do not take her seriously or give her the attention she wants. Although she treats her friends kindly and rarely holds grudges against them, she is usually brutal towards her enemies.

In earlier episodes, she also holds a prejudice against monsters, believing they are "born bad", though this opinion softens a little as of "Mewnipendance Day". As the series continues, however, her prejudice softens more or is gone completely, shown by her being friends with Buff Frog and his tadpoles and her disapproval of her mother's own prejudice in Star vs. the Forces of Evil: The Battle for Mewni. By "Starfari", Star has started advocating for fairer treatment of monsters in Mewni.

She sometimes chews on the top of the wand, in something of a tic.[39] She also has a habit of kicking in doors.[40]

In "Sleep Spells", she is revealed to have issues with her mother and ruling over the kingdom one day.

As the series progresses, Star becomes less prone to resorting to magic to fix a situation, and she shows a willingness to become stronger and more serious and not run away from her problems, despite this sometimes resulting in her underestimating her enemies. After Toffee's defeat, she decides to focus on becoming a better princess and starts to act more serious, mature, and responsible as a result.

After discovering she is not a true member of the Butterfly family, Star begins to have doubts about her place in royalty, to the point she feels compelled to return the royal magic wand to Eclipsa at the end of "Conquer".

Abilities

 * Royal magic wand: Star wields the Butterfly family's royal magic wand which grants her multiple magical powers, though she does not fully understand them yet. She can summon many different creations or change anything she wants with the wand just by saying spells and pointing it. Star can also transform her wand into other things, like a mace or umbrella. In "Conquer", she returned the wand to Eclipsa.
 * Hand-to-hand/armed combat: Star also knows how to fight without the wand, either fighting unarmed or using a weapon. As a toddler, she was taught how to break a neck with her bare hands and the art of swordsmanship by the Mewni royal guard.
 * Agility/dexterity: Star demonstrates tremendous agility and physical prowess throughout the series, such as sprints, midair flips, and perfect balance.
 * Mewberty form: In "Mewberty", Star goes through mewberty and develops a "half-butterfly" form that grants her flight and web-shooting powers. As of The Battle for Mewni, Star's mewberty form becomes considerably more powerful after she gains a new wand. In "Sweet Dreams", Star can also travel between dimensions in this form without dimensional scissors. Star gains full control over this form in "Deep Dive". As seen in "Conquer" Star's mewberty form also increases the power of her spells exponentially to the point where her attacks are able to hurt an empowered Meteora.
 * Innate magic: In "My New Wand!", Star learns to "dip down" and access the innate magic within her own body and amplify her wand's magic. According to Baby, Star is the strongest innate magic user since Queen Eclipsa. In "Toffee", Star proves powerful enough to restart magic throughout the universe by using her innate magic to birth a new Millhorse from the last fragment of magical energy in the universe. By season 4, Star has become very proficient in casting magic spells without a wand.
 * Flight: In "Mewberty", Star grows a pair of small wings and can use them to fly temporarily. She is shown using these wings to cross over a sinkhole in "Star on Wheels". After gaining full control over her Mewberty form, she is able to fly freely and practically effortlessly.
 * Creativity: Star has also demonstrated a talent for paper cutting, painting, and drawing. She also makes up her own spells using her imagination.
 * Equestrianism: In "Star Comes to Earth", Star states in narration that she tames wild unicorns as a hobby. In "Raid the Cave", she briefly engages in combat while on horseback.
 * Diplomacy: Star has shown great charisma in her goal to achieve equality between mewmans and monsters. She was able to garner respect and admiration from the monsters and was able to bring momentary peace between mewmans and monsters during "Monster Bash". In "Is Another Mystery" Buff Frog tells her that he and the other monsters will return, once Star becomes the ruler of Mewni.
