The Girlaxy/The Solar Sisterhood
open/close all folders
The Girlaxy as a Whole
- Ambiguously Human: It is unknown where exactly the Galaxy Girls originated. With the obvious exception of Mars, they're most likely Human Aliens.
- Anthropomorphic Personification: The girls tend to refer to themselves as if they were themselves the heavenly bodies they represent, such as Sun saying she makes up 99% of The Solar System's mass, and Jupiter taking about how Galileo changed the understanding of the cosmos by discovering her moons.
- Art Major Physics: Yes, it's a team of girls having adventures and saving the day whilst skating/flying in the vacuum of space. You should really just relax.
- Captain Ersatz: Much like how Faust based My Little Pony: Friendship Is Magic on her interpretation of classic My Little Pony, Galaxy Girls is inspired by Strawberry Shortcake
- Improbably Female Cast: The jury's still out on Black Hole though.
- Magical Girl: All of them. From the pre-production materials that Faust has made, all of the girls appear to at least have the ability to freely move through outer space. They also have to fight at least one Big Bad.
- Motifs: Each girl wears roller-skates, probably meant to emphasize their ability to freely move about space.
- One Of These Things Is Not Like The Others: So, wait, where's the character that represents/personifies planet Earth? Well, there is actually such a character, but "Mother Earth" has only been briefly mentioned by Faust in a forum post. That said, Lauren Faust's call-sign on the Galaxy Girls blog is Mother Earth, whatever that means.
- Noodle People: They tend to be tall and have thin limbs.
- Positive Discrimination: Largely averted. Each character has one or more shortcomings that work to counterbalance their amazing abilities, talents, and personalities.
- Rollerblade Good: Especially for space travel!
- Sailor Earth: There are also a few fan-made Earth-characters out there as well.
- Shout-Out: Obviously. The whole thing is based off of various celestial bodies, with each character's design and personality reflecting at least one physical property (The Sun's energy, Pluto's icy demeanor, etc.) or cultural/mythological associations (Venus's association with romantic love, Uranus's insistence that you pronounce her name right, etc.) with their associated celestial body. Here's a quick summary:
- The Milky Way is the spiral-shaped galaxy in which you, I, the Sun and its orbiting bodies, koala bears, between 200 and 400 billion other stars of varying size, and 100 billion additional planets are held together by the gravitational effects of its visible and dark matter. Andromeda is the nearest neighboring spiral-shaped galaxy, a mere 2.5 billion light years away from Earth. Andromeda is thought to be younger than the Milky Way by approximately 4.2 billion years.
- The Sun is based off of... well... the Sun, a star that holds our Solar System in place via it's gravitational pull. This particular star is sometimes referred to as Sol.
- Mercury, Venus and Mars are based off of the smaller, rocky planets that orbit nearest to the Sun, while Jupiter, Saturn, Uranus and Neptune are based off the gaseous giants that orbit further out.
- The Moon is based off of Earth's Moon. Jupiter's pets are named after Io, Callisto, Europa and Ganymede, Jupiter's four largest moons, which are sometimes referred to as the Galilean Moons.
- Pluto, Eris and Ceres are based off of dwarf planets, which are commonly defined as being massive enough to have their shape dictated by their own gravitational pull, but lacking the needed gravitational force to clear their orbits around the Sun of other bodies of comparable size. Pluto and Eris are small, icy worlds beyond the orbit of Neptune, while Ceres is the largest object residing in the Asteroid Belt between Mars and Jupiter.
- Black Hole is based on the spatial phenomenon of the same name, in which a sufficiently massive star collapses in on itself when the force of its own gravitational pull exceeds the outward force of its internal fusion (which commonly happens as the star burns through heavier and heavier elements), the end result being a singularity with such powerful gravitational force that even light entering its event horizon cannot escape.
- Symbol Motif Clothing: Each girl also has a unique symbol (Milky Way's star, Venus's heart, etc.) that they wear as earrings and on the wheels of their skates, which represents some aspect of their personality. The only one that doesn't is Ceres, which is one part a reflection on her personality, one part character development, and one part Lauren Faust having not decided on her symbol yet.
- Vague Age: So far, only Milky Way and Andromeda have had their ages revealed, being 15 and 5, respectively. It's easy to assume the other Galaxy Girls are teenagers as well (though some fans like to assume that Sun and Jupiter are in their 20s due to their taller appearance). This is further complicated when you consider that the bodies they equate themselves to are billions of years old. Perhaps they are just physically and mentally young while chronologically being Really 7 Billion Years Old.
The starry-eyed front-woman of the Galaxy Girls, Milky Way is "what every girl wishes she was but doesn't know she is already: smart, confident, adventurous, and fun". She lives to explore the cosmos and make new experiences and friends, although her craving for adventure has a tendency to get in the way of common sense. Still, she's more than capable of getting out of any jam she gets in. Recently received a redesign making her less of a Noodle Person.
- Bare Your Midriff: Not enough to expose any bellybutton, but still there.
- Challenge Seeker: One of her defining traits. She's not satisfied unless she gets to experience new places and things.
- Color-Coded Characters: A combination of navy and pale blue and light yellow, the colors of a starry night.
- Cool Big Sis: To Andromeda
- Conflict Ball: About her only flaw according to Faust's website is that she's sometimes overly adventurous, which can lead to trouble for her and the other girls.
- Hair of Gold, Heart of Gold: She has platinum-blonde hair, and is plenty willing to make friends and right any wrongs in the galaxy.
- Innocent Blue Eyes: To go with her platinum-blonde hair.
- The Leader: Presumably, she's the de-facto leader of the Galaxy Girls. She would probably fall into the Charismatic, Headstrong, or Levelheaded categories.
- Must Make Amends: It's highly implied that she's always willing and able to help fix whatever problem she's uncovered during the course of her adventures.
- Nice Job Breaking It, Hero!: She accidentally frees the series's Big Bad, Black Hole, in one of Faust's drafts for the pilot of the show.
- Plucky Girl: In Faust's words, "not even the force of gravity can keep her down!"
- The Power of Friendship: She's constantly seeking out new friends if she isn't seeking out new places or experiences.
- Rapunzel Hair: It reaches her knees!
- Symbol Motif Clothing: A star.
- Stealth Pun: Both literally and figuratively starry-eyed.
- Wingding Eyes: Interestingly, she's the only one (along with her sister Andromeda) with a unique shape in the light reflected off her pupils, which are stars as opposed to circles.
Like The Sun itself, Sun is the center of attention. The world revolves around her, and she'll make sure you know it! Energetic, confident, passionate, and HOT, Sun keeps the Solar Sisterhood warm with her heavenly voice.
- Attention Whore: To an extent.
- Bare Your Midriff: Again, her top doesn't reach her hips, but her navel isn't exposed.
- Character Blog: Solar Power
- Color-Coded Characters: Loves yellow and orange!
- Curtains Match the Window: Both are bright orange.
- Dark-Skinned Redhead: Her tanned complexion and orange hair overlaps this with Dark-Skinned Blond.
- Disco Dan: Her design has some elements of this.
- Fun Personified: Just radiates this.
- Fun T-Shirt: Her tank top reads, "HOT".
- Funny Afro: One that looks like the Sun itself.
- Hot-Blooded: Is incredibly passionate about her musical talents, like Pluto, but without the violence!
- Iconic Item: Her microphone.
- Idol Singer: Played straight and subverted. Visually, she has all the stylings of one. Despite that and the fact that she's all about fun, she does have genuine musical talent, with her voice described as "heavenly".
- Large and in Charge: Like Jupiter she's one of the tallest characters. She's also extremely confident, assertive, and believes everything else is orbiting around her singing talents. Oh, uh, she's also the frickin' personification of the Sun!
- Magic Idol Singer: Her singing illuminates the entire Solar System!
- Red Oni, Blue Oni: Forms a pair with the melancholy Moon, who is the other confirmed lyricist in the group.
- Sassy Black Woman: Radiance like that doesn't come out of nowhere, after all.
- Shout-Out: She prides herself on being HOT and the center of attention, much like The Sun is the center of the Solar System and generates intense heat.
- Spiritual Antithesis: Despite she and Celestia sharing association with the Sun, the two are very much opposites. Whereas Sun is all about being the center of attention, Celestia wishes to be thought of as simply another pony rather than put on a pedestal.
- Symbol Motif Clothing: A twelve-pointed sun.
- Who Wears Short Shorts?: HOT pants, to be precise.
- You Are the New Trend: She either tries to set the trends or flows with them.
As befitting of the name, Mercury prides herself on being the fastest in the galaxy, and is said to be able to reach the speed of light with her winged sneaker-skates. She's always working out to maintain her athletic ability, but as a result doesn't spend as much time with her friends as they'd like.
- Bare Your Midriff: Unlike the first two examples, her tank is short enough to display her bellybutton.
- Blessed with Suck: She's as fast as the speed of light! However, this magical skill apparently requires an intense physical regimen to maintain, so Mercury is often away from her friends exercising and training. Although she doesn't seem to intentionally blow them off, the other Galaxy Girls often notice her absence and wish she'd spend more time with them.
- Boyish Short Hair: As someone who prefers athleticism over socialization, she keeps her hair short.
- Color-Coded Characters: She likes light blue and silver.
- Determinator: She won't let anything keep her from being fastest in the galaxy.
- Jerk Jock: A downplayed female example. She's not outright mean — in fact, she's got a positive attitude in general — but her competitive nature means that she'd often rather be training for a track event rather than hanging out with her friends, which they sometimes wish Mercury would do more often.
- Mercury's Wings: Just like her namesake.
- Red Oni, Blue Oni:
- Both Venus and her are competitive athletes to the point of perfectionism in their respective activities. However, Mercury is much more blatant about her competitive drive, relentlessly training for track much of the time at the expense of alienating some people. While Venus is just as dedicated to dance, she's perceptive enough to realize that a constant, open display of this might be a turn-off, and therefore makes sure to approach people with a polite and unassuming manner.
- The contrast between red-oni alpha competitor Mercury and blue-oni beach bum Neptune is much more straightforward.
- Shout-Out: To both the planet Mercury and the mythological Mercury. The planet Mercury, which is the planet situated the closest to the sun, orbits completely around it at a faster rate than any of the other planets do. The ancient Roman deity Mercury was also fast, being a cosmic messenger and light god and all.
- Super Speed: Her talent. She's the fastest thing in the Galaxy Girl-universe and, with her skates equipped, it's possible for her to travel at the speed of light.
- Symbol Motif Clothing: Her Mercury's Wings.
- Tank-Top Tomboy: The right clothes to push it to the limit.
- Tomboy: Most definitely.
- Tomboy and Girly Girl: With Venus.
- You Gotta Have Blue Hair: A dark silver-ish blue, to be precise.
What Mercury is to speed, Venus is to beauty, wowing the Solar Sisterhood with her graceful appearance and dance moves. She's not to be taken lightly, though, as those moves demand a great deal of mental and physical discipline.
- Ballet: She likes all kinds of dancing, but her favorite form of dancing is ballet.
- Beauty, Brains and Brawn: She has all three going for her. Her dance moves demand both an agile, coordinated mind, and immense strength and endurance, all of which she's got.
- Color-Coded Characters: Pink, pink, and more pink. Also fuchsia and lavender.
- Dancing Is Serious Business: This is her passion for dancing mixed with her inner drive for perfection.
- Determinator: She never gives up, at least when it comes to improving her ballet skills.
- Girly Bruiser: Her bios make a point of the great amount of strength and coordination it takes to preform ballet as well as she does, so it's likely she'll develop this once Galaxy Girls gets off the ground.
- Girly Girl: The girliest in the galaxy.
- Love Goddess: Even based on one!
- Magical Girl: Well, they're all technically Magical Girls, but Venus's ballerina get-up and frilly ribbons arguably invokes the stereotypical image of such a character best of all the girls in the group.
- Peek-a-Bangs: Her hairstyle is both unassuming and alluring.
- The Perfectionist: Her desire to master her ballet can get carried away sometimes, which is her main shortcoming.
- Pink Means Feminine: As the most traditionally feminine of the Galaxy Girls, it's only natural that she's decked out in pink from head to toe.
- The Power of Love
- Proper Lady: At least on the outside, she projects this image.
- Rose-Haired Sweetie: She's very nice and polite, with pink hair to boot.
- Shout-Out: The planet Venus is named for the Roman goddess of Beauty, due to the way it resembles a beautiful star in the night sky. Plus, Venus or Aphrodithe was also a godess known for many Disproportionate Retribution, reflected in Venus' Silk Hiding Steel.
- Symbol Motif Clothing: A heart.
- Tomboy and Girly Girl: With Mercury.
- Tutu Fancy: Of course, she usually preforms in zero-gravity, so I guess we can give her a free pass. That said, there is a piece of concept art of her wearing a more practical uniform.
- You Gotta Have Blue Hair: No, you gotta have pink hair!
If there's a beauty in sadness, Moon personifies it. Her emotions ebb, flow, wax, and wane as much as her namesake, but her emotional nature inspire some of the most incredible poetry you can imagine.
- Color-Coded Characters: White and grey like The Moon itself.
- Cursed with Awesome: The same moodiness that drives people away from her also provides the inner conflict needed to generate her awesome poetry and music, which somewhat draws them back.
- Curtains Match the Window: At least with with the more darkly shaded parts of her hair.
- Deliberately Monochrome: To an even greater extent than that of Pluto!
- Drama Queen
- The Eeyore: She almost always looks like she's one second away from weeping.
- Emo Teen: She can be considered as much, as a girl who revels in her unhappiness and writes poetry.
- The Friend Nobody Likes: Her signature moodiness makes it very hard for anybody to spend any great amount of time with her. But on her best days, her awe-inspiring songs and poetry makes it all worth it... Almost!
- Large Ham: Although the Moon is a gifted poet, her talent derives itself from her turbulent emotional state, making her works at times very melodramatic relative to other people.
- Melancholy Moon: She is this trope.
- Mood-Swinger: Said to be this, though melancholy seems to be her default mood.
- Rapunzel Hair: Like Milky, it reaches her knees.
- To The Moon's tidal effects on the Earth in Real Life. The Moon's emotional state ebbs and flows with time as well, making her the most unpredictable of the Galaxy Girls.
- Her choice of dress and fascination with the more morbid side of things also calls to mind turn-of-the-century Spiritualism.
- Her overall willowy design resembles many ladies depicted in Art Nouveau.
- Spiritual Antithesis: She and Luna are both associated with the moon and present a unique combination of shy and bombastic, but Moon is far more on the "shy" side with Luna on the "bombastic" side.
- Symbol Motif Clothing: A crescent moon.
- True Art Is Angsty: In-Universe, her repertoire includes "beautiful bittersweet ballads, splendidly sorrowful sonnets, lovely lamentable lyrics, awesome ominous odes"... you get the picture.
- When She Smiles: Although her most accessible artwork depicts her giving a shy smile, the majority of her renderings from Faust has her sadly frowning instead.
Mars takes "out of this world" to a whole new level, in both appearance and demeanor. Her happy-go-lucky mind and perception of the universe are absolutely nothing like yours and mine. She's also an accomplished artist, her works looking like nothing you've ever seen.
- Bizarre Alien Biology: Aside from being green, those antennae of hers are real.
- Cloud Cuckoolander: Have you seen the way she dresses?!
- Color-Coded Characters: As befitting her oddball personality, she exhibits all of the secondary colors, with green being the most prominent.
- The Ditz: To a limited extent.
- Fun Personified: She has a giddy demeanor, is always laughing and leaping, and her main interest is arts and crafts of any kind.
- Fur and Loathing: Averted; She's not at all vindictive or evil, and considering Faust's own love of animals, it's very unlikely her fuzzy jacket is actual fur. It serves more to highlight her kookiness and individuality.
- Genki Girl: Once inspiration strikes, there's no holding her back.
- Green-Skinned Space Babe: All of the girls are extraordinary, but she's the only one that is genuinely out of this world — that is to say, an extraterrestrial.
- One Of These Things Is Not Like The Others: She's the only honest-to-god alien in the group.
The spiritual hippie chick of the Girlaxy, Jupiter strives to become "one with the universe". As such, she's always organizing cosmic cleanup efforts and rescuing animals. Her favorites, and first ones rescued, are Io the Pup, Callisto the Cat, Europa the Bunny and Ganymede the Ferret.
- Bare Your Midriff: Her wide-sleeved belly-shirt really sells her hippie look.
- Character Blog: Peace Throughout the Universe
- Color-Coded Characters: Brown, pink, light yellow and cranberry.
- Expy: Shares Fluttershy's love of animals and Applejack's work ethic and practicality.
- Facial Markings: She has an Indian bindi on her forehead.
- Friend to All Living Things: She dearly loves animals, especially her many rescued pets.
- Gentle Giant: The "gentle" part definitely qualifies. And in the few group compositions that exist, she's usually one of the tallest characters. Her sprawling hair also makes her more noticeable as well.
- Granola Girl: In addition to her dress and love of animals, she also regularly organizes efforts to clean up broken satellites and other space junk littering the solar system.
- Hair Decorations: Her headband.
- New-Age Retro Hippie: She's described as a hippie on Faust's website. Another aspect of her personality is that she's very spiritual, constantly seeking to become one with the universe.
- Purple Eyes: Deep purple eyes to reflect her spiritualism.
- Rapunzel Hair: Seriously, it's ginormous.
- The most noted features of planet Jupiter are its enormous size and numerous moons, both of which are represented by Galaxy Girl Jupiter's tall frame / voluminous hair and many pets.
- Her lightning bolt symbol may also tie in to Jupiter's stormy surface and to the Roman God Jupiter (also known as Zeus)'s lightning association.
- The bindi on her forehead and the small cranberry-colored circle on each of her pant legs may be references to her planet's Great Red Spot.
- Symbol Motif Clothing: A lightning bolt.
Jupiter's Pets, Io the Pup, Callisto the Cat, Europa the Bunny and Ganymede the Ferret
- Amazing Technicolor Wildlife: Callisto the Cat has pink fur.
- Art Major Physics: Even more egregious than that of the girls themselves! So, the girls are free to do their thing in space without the use of thrusters or helmets, but Jupiter's pets have to have them? But they aren't bothered by direct contact to that harsh vacuum?
- Bunnies for Cuteness: Europa the Bunny
- Cool Helmet: Retro-style bubble helmets complete with antennae. Curiously, Callisto's helm has six antennae positioned like whiskers.
- Cute Kitten: Callisto the Cat
- Happily Adopted: Jupiter rescued all of them.
- Precious Puppy: Io the Pup
- Ridiculously Cute Critters:
- Seldom-Seen Species: Ganymede the Ferret
- To Jupiter's famous four Galilean Moons, obviously. In all the official art that they appear in, they are constantly orbiting Jupiter.
- Furthermore, Io the Pup bears a strong resemblance to Laika, one of the first animals launched into space.
- Retraux: The designs of their bubble helmets and jetpacks are very retro.
In addition to her many rings, Saturn is the chief music mixer in the Solar Sisterhood, busting phat beats on the turntables at her dance club.
- Bare Your Midriff: To show off her belly-ring, of course!
- Color-Coded Characters: She's fond of yellow, purple, and teal.
- Flat Character: Overall, Saturn is the least developed of the 11 main Galaxy Girls. Compared to the other's characteristics and quirks, simply liking music and rings is somewhat underwhelming.
- Genius Bonus: In real life, Saturn is the only planet in the solar system that actually puts out a sound.
- Headphones Equal Isolation: Averted. She operates her own club / skating rink on the actual planet of Saturn, which is seen to be packed with patrons, and she readily assists Milky Way to find a fragment of Black Hole's prison. As much as Saturn likes music, her headphones are also part of her job as a deejay.
- Hip-Hop: Begins to approach the musical genre that influenced her design (perhaps most notably her ridiculously-ostentatious pants!) / presumably informs her own musical tastes. However, this seems to be blended with a generous amount of dance-inspired influences as well.
- Iconic Item: Her headphones.
- Rapunzel Hair: It's done up in a ponytail, but it's still likely it reaches her knees.
- Sassy Black Woman: Not the extent of sun, but it's there.
- Shout-Out: Her many rings are obvious parallels to the planet Saturn's rings.
- Symbol Motif Clothing: A classic "planet with ring" image.
- Tomboyish Ponytail
- Up to Eleven: Her passion/obsession for golden rings. She's got three bracelets on each arm, two large hoop earrings, small nose and belly rings, and either rings or yellow scrunchies in her hair. She's also maintaining the height of two large hula-hoops in much of her official art. It's a miracle she can get anything else done!
- You Gotta Have Blue Hair: Purple, to be exact.
Uranus (pronounced YOOR-en-us, not yoor-A-nus, at her insistence) is a total perfectionist. She's a firm believer in the old adage that the most important learning happens when you're young, and as such is always studying all sorts of academic subjects and riding her twin sister, Neptune, to take her own studies more seriously.
- Bookworm: Whether calculus, quantum physics, or the occasional romance novel, Uranus almost always has her nose in a book.
- Color-Coded Characters: Light and navy blues, green and white. Also notable is that the Uranus and Neptune siblings share different shades of blue hair.
- Education Mama: Played with. She's somewhat distressed about her sister Neptune's lack of enthusiasm about her own studies, and will always correct those that mispronounce her own name!
- Foolish Sibling, Responsible Sibling: Perhaps somewhat averted, in that Neptune gets along fine in spite of her lack of enthusiasm for studying. But Uranus won't stop hounding her about this, primarily because she genuinely cares about her sister's future.
- Heh Heh, You Said "X": The eternal victim of this.
- Meganekko: Oh yeah.
- Never Live It Down: In-Universe, she's mainly known as the butt of cosmic jokes thanks to a common and humiliating mispronunciation of her name (it's YOOR-en-us, guys! YOOR-en-us!), but those that know her better know that she's a practical, scientifically-minded intellectual with a bent towards education and responsibility.
- The Perfectionist: But really only when it comes to her studies.
- Romance Novel: In her downtime, she enjoys reading these.
- Sibling Yin-Yang: With Neptune.
- Symbol Motif Clothing: An apple.
- Teen Genius: She's at the very least acquainted with both calculus and quantum physics thanks to her studies.
- Uranus Is Showing: *Sigh* For the last time, it's YOOR-en-us!
- You Gotta Have Blue Hair: The straightest example in the Girlaxy.
Neptune, naturally, lives for the seas of the universe. Whether hanging ten or just hanging out, she's a laid-back, "go with the flow" kind of person, which puts her at odds with her diligent sister, Uranus.
- Bare Your Midriff: Continues the trend.
- Book Dumb: She's not dumb by any means, but she'd rather relax and play in the water than take the time or effort to sit down and study. It's worked out pretty well so far.
- Color-Coded Characters: All derived from the sea. Specifically, she prefers teal, sea foam blue, and hunter green.
- Cool Board: She's the only one with one!
- Cool Shades
- The Ditz: Just a little.
- Don't Think, Feel: Her talent at surfing and other water sports probably developed simply because she liked doing such things so often.
- Foolish Sibling, Responsible Sibling: She's nominally the foolish one and her bookworm sister is the responsible one. Not that this bugs her or anything.
- Red Oni, Blue Oni: The ultimate blue oni, befitting her laid-back personality and penchant for water sports, although she's not at all chilly. Unlike Mercury or Venus, Neptune isn't participating in her activities to be the best; she just wants to have fun. The same goes for academics, which bugs Uranus to no small degree.
- Surfer Dudette
- Shout-Out: The planet Neptune is named for the Roman god of the Sea due to its deep blue appearance, hence Galaxy Girl Neptune's love of swim and surf.
- Symbol Motif Clothing: A clam-shell.
- Who Wears Short Shorts?: Even if she's not going as far as a Walking Swimsuit Scene, she still dresses lightly for when the waves are a-calling.
- You Gotta Have Blue Hair: Neptune has a shade that's brighter and not as intense as her sister's blue hair.
Pluto and the Dwarf Planets
- Out of Focus: Pluto's band-mates are this, well... as much as an element of a show in its planning stages can be out of focus. Generally, Eris and Ceres are the least developed of the characters mentioned by Faust aside from Black Hole. They have yet to receive published clean line-art, and Ceres's personal symbol hasn't been finalized yet.
- Red Oni, Blue Oni: Eris and Pluto share the red oni within the band, while Ceres has sole possession of the blue oni.
- Rock Trio: Pluto is the lead guitarist, Ceres is the bassist, and Eris is the drummer.
A rule-breaking rebel, Pluto is as cold and hard as the death metal music she plays, and she loves it, even if it might be what got her demoted to Dwarf Planet. Despite her stone cold attitude, Pluto's still a very passionate person, and she'll always stick up for her friends... possibly violently.
- Cute Bruiser: Just don't call her that to her face.
- Character Blog: Dwarf Planet THIS!!!!!
- Color-Coded Characters: Black and white, as well as lavender eyes.
- Dark Is Not Evil: Let's see... Morbid fashion? Check. Brooding demeanor? Uh-huh. So she must be evil, right? Nah, she's just really good at kicking butt.
- Deliberately Monochrome: The only bit of color on her are her pale lavender irises and rose red lips.
- Eerie Pale-Skinned Brunette: She tries to give off this image, but she's not all bad when you get to know her.
- Pluto Is Expendable: ...Look, it had to be mentioned...
- Heavy Metal: SHE LOVES HARD ROCK!! AND PLAYING THE GUITAR!! So much so that she's formed her own band, "Pluto and the Dwarf Planets" with her friends Eris and Ceres!
- Hot-Blooded: In spite of her icy reputation, she's extremely passionate about the things that she cares for.
- Jerk with a Heart of Gold: She's got an attitude, but she's all good beneath all that.
- Might Makes Right: A rare heroic example. Pluto deals with threats and other problems with brute force. Fortunately, she's also extremely loyal to her friends and always willing to back them up when the going gets rough.
- No Indoor Voice
- Perky Goth: She's a lot friendlier than she seems.
- Rapunzel Hair: Once again, it reaches her knees.
- Shout-Out: Pluto's cold, hard demeanor likely comes from Pluto being a ball of ice far away from the Sun. Her love of Death Metal may also tie in with the Roman God Pluto being the god of death.
- Sir Swears-a-Lot: No-one else here needed grawlixes censoring their language!
- Sugar-and-Ice Personality: With a heavy, heavy skewing towards the "ice" side of things. If you cross her, she won't hesitate to give you dirty looks or scare off your younger siblings. But befriend her and you've got an ally for life that will always lend a hand in a brawl.
- Symbol Motif Clothing: A skull.
- Unkempt Beauty: Her hair in particular is just out of control.
The drummer for Pluto and the Dwarf Planets, Eris is a take-charge hothead who is best not crossed.
- All Drummers Are Animals: She's more enraged than most examples, but she definitely has the chaotic nature down.
- Color-Coded Characters: Not officially stated, but Eris seems to love intense neon maroons, purples and greens.
- Color-Coded Eyes: Her green eyes are fitting for the most down-to-earth member of the Dwarf Planets.
- Fiery Redhead: with several little neon streaks to make it look more like a blast of energy.
- Hot-Blooded: Eris's known personality trait. Much like her friend Pluto, she takes her drumming extremely seriously and hates it when other people get in the way of that.
- Punk Punk: What her design is largely going for. More specifically, she contains elements of Diesel Punk and Cyber Punk to a lesser degree.
- Punk Rock: The musical genre and general fashion trend that Eris follows.
- Red Eyes, Take Warning: They add to her intense appearance!
- Shout-Out: In Real Life, the Dwarf Planet Eris is named for the Goddess of Chaos.
- Symbol Motif Clothing: An atom.
- Unkempt Beauty: Though she's likely not to keen on being called a "beauty".
The bassist of Pluto and the Dwarf Planets, Ceres is a non-conformist who eschewed having a personal symbol, but has since decided that blindly rejecting trends can be just as bad as blindly following them. The problem is that she still doesn't know what her symbol should be.
- Alternative Indie: Probably the best way to describe Ceres's own musical tastes and overall fashion sense.
- Ascended Fanon: Maybe someday. On Faust's DeviantArt page for Ceres, she mentions that she'll consider suggestions for Ceres's symbol in the comments section below.
- Color-Coded Characters: Not officially stated, but Ceres prefers more muted earth tones.
- Disobey This Message: Played With. Initially, she didn't have a symbol because she was very non-conformist. But then she decided to adapt one because sometimes bucking a trend can be as bad as getting on board with it. She has yet to decide which symbol to use.
- Hipster: Hence why she's taken so long to adopt a personal symbol.
- Hand Wave: Why doesn't Ceres have a symbol yet? The in-universe explanation is that she hasn't decided on one yet! The real world reason is because Faust hasn't decided on one yet.
- Nerd Glasses: Has a pair of them.
Andromeda is Milky's adorable 5-year-old sister, always eager to hear about her latest adventures.
- Cheerful Child: Just look at her...
- Color-Coded Characters: Not official, but her artwork depicts her wearing pale violets and yellows.
- Curtains Match the Window: Lilac hair and eyes.
- Expy: She's the Spike / Cutie Mark Crusaders parallel, being a younger sibling character who looks up to her older sister. Her cutesy appearance and demeanor also bring to mind The Powerpuff Girls (which Faust also worked on), specifically Bubbles.
- Girlish Pigtails: Her innocent nature is tied up perfectly in two pigtals.
- Hair Decorations: Unlike the other girls, Andromeda has star-shaped hair decs for her pigtails, since she's too young for earrings.
- I'm Your Biggest Fan: She idolizes her older sister and her exploits throughout the universe.
- Kid-Appeal Character: She's clearly meant to be the audience proxy, representing all the little kids who look up to the Galaxy Girls, Milky Way in particular.
- Purple Eyes
- Shout-Out: To the real-life relation of the Andromeda and Milky Way Galaxies. Not only is the Andromeda Galaxy the closest spiral-shaped galaxy to the Milky Way, but it's also younger than the Milky Way, aged 9 billion years as opposed to 13.2 billion years. So it makes sense that Andromeda is Milky's younger sister.
- Wingding Eyes: Shares Milky's starry eyes.
- You Gotta Have Blue Hair: Has pale purple hair.
The Big Bad of the series and primary antagonist of the Galaxy Girls. He/She/It was freed from its planetoid prison after Milky Way touched it while wandering outer space, shattering it into 11 pieces and scattering them to different places in the Solar System. Unless he's/she's/it's contained again, Black Hole will generate a vortex capable of sucking up everything in the Universe! Even without his/her/its ability to erase everything from existence, Black Hole is still said to be one nasty customer.
- Ambiguous Gender: Since we still know very little about him/her/it.
- Apocalypse How: We've got a Class X 4 situation on our hands. Sure, the larger multi-verse will be fine, but this universe will be hurtin'.
- Big Bad: The first and so far only villain the Galaxy Girls face.
- Sealed Evil in a Can: Well, it was until Milky Way's curiosity got the better of her.
- Omnicidal Maniac: Either doesn't care or isn't aware that everybody in the Universe is threatened with destruction thanks to its vortex.
- Out of Focus: Simultaneously averted and played straight. Averted because we know of Black Hole's larger place in the story and his/her/its origins based upon the few story ideas and story boards Miss Faust has released online, something that can't be said for any other character except for Milky Way herself and Saturn. Played straight because we know the fewest details about him/her/it out of all the characters Faust has revealed, including its gender or lack thereof and any details about its appearance or anything of depth about its personality.
- Power of the Void: Enough power to pose a threat to the entire universe.
Super-cute extraterrestrials that love to party at Saturn's place. Appear to be somewhat similar to but distinct from Mars.
- Amazing Technicolor Population: Come in pink, yellow, green, blue, and purple varieties.
- Bizarre Alien Biology: Their only unusual anatomy (aside from being diminutive compared to the Galaxy Girls) are their antennae, which they share with Mars.
- Dance Sensation: They are enraptured by Saturn's talent as a deejay. Saturn is able to take advantage of this by controlling their position on her dance floor until they're in one giant column, allowing Milky to find one of the eleven fragments of Black Hole's prison.
- Dancing Is Serious Business: It doesn't start out that way, but as Saturn's music becomes more frantic, they begin to don slightly-more serious expressions.
- Faceless Masses: Almost, but not quite.
- Innocent Aliens: Their numbers and love of dancing make Milky's search for the first of the shards of Black Hole's prison difficult for a while, but that's all the harm to come from them.
- Little Green Men: And pink, and purple, and so on...
- Ridiculously Cute Critter: I mean, look at them!
