- Astonishingly Appropriate Appearance: Each summon bears at least a minor resemblance to what they're supposed to be.
- Immortality: This is a default power.
- Narnia Time: One day in the Celestial Spirit World is equal to three months in the human world.
- Nigh Invulnerable: They can be hurt with conventional attacks, but they'll recover with little to no permanent scars. The only way to really hurt them is to make them stay in the human world longer than they are capable of, at which point they fade away and die. And Leo and Capricorn manage to overcome that obstacle as well.
- Not Themselves: During the Eclipse Celestial Spirit Arc, something starts affecting the Gold Key Spirits that causes them to rebel.
- The Pirates Who Don't Do Anything: In the beginning of the story, the Zodiac spirits Lucy has collected so far aren't particularly useful in battle and are used moreso for mundane things (getting a new hairdo, getting hit on, etc...). No wonder Lucy wants to collect more keys!
- Stellar Name: All come from constellations.
- Super-Powered Evil Side: In the filler arc after the magic games.
- Theme Naming: All spirits are named after their respective constellations; however, most if not all lesser spirits are actually just one of a species, and get their own names.

Celestial Spirit King
Celestial Spirit King
Voiced by: Norio Wakamoto (JP), Cole Brown (EN)
The ruler of the Celestial Spirit World and its residents, as well as the strongest of the Celestial Spirits. He can only be summoned by a Celestial Spirit Mage who sacrifices a Gold Key of a Spirit whom the summoner has a strong bond with.
- Anti-Magic: "Galaxia Blade", his most powerful ability, uses the pure light of the stars to break even the darkest curse.
- Arch-Enemy: To Mard Geer.
- Authority Equals Asskicking: King of the Celestial Spirits and the most powerful of them all.
- Badass Arm-Fold: Kept his arms folded in a rather cool manner throughout his first appearance.
- Badass Cape: Complete with Dramatic Wind.
- Badass Grandpa: He has the appearance of an older man, but is extremely powerful, as shown by the destruction he causes when he finally fights.
- Badass Mustache: A magnificently huge one.
- Battle Aura: Can unleash a destructive one when angered.
- Berserk Button: Make Lucy suffer and he'll destroy your entire guild headquarters without prejudice!
- BFS: Wields an extremely powerful longsword decorated with star imagery. Considering how huge he is, that just makes it even bigger.
- The Bus Came Back: After being gone for a long time, he finally reappears in the Tartatos arc to save Lucy and destroy Cube.
- Cool Old Guy: Has the appearance of an old man, but not only does he look cool and intimidating, he's extremely strong.
- Cool Helmet: Wears a really nice-looking and intimidating horned helmet that shows his face and is also decorated with fins and a upside-down star.
- Cool Sword: His BFS is richly decorated with star imagery and is powerful enough to cut one of the most powerful Dark Guilds' travelling headquarters into several pieces.
- Did You Just Flip Off Cthulhu?: Lucy, did you just defy the Celestial Spirit King? And he listened?
- Dynamic Entry: Makes an epic grand entrance when Lucy manages to summon him following Aquarius's sacrifice. He makes his appearance by slicing the Tartaros's headquarters, Plutogrim, into pieces.
- Expy: Of Odin. As in "the summon from the Final Fantasy series". If someone who has seen the Dynamic Entry above tells you they didn't think of Zantetsuken, they lie.
- Godzilla Threshold: Summoning him requires the sacrifice of one golden key. Meaning, that they can never summon them again. Therefore, summoning him is considered as a very last resort
- Infinity+1 Sword: In a way, as a Celestial Spirit Mage can only summon him if they can summon three spirits at a time, which itself requires large magic reserves and has presumably never been done before until Lucy does.
- Large and in Charge: King of the Celestial Spirits and a huge giant that towers over everybody.
- Large Ham: Not only that, but half the fandom fell over in their chairs when they heard who was doing his voice.
- Power at a Price: It is possible to summon him. The toll though? One must destroy a Celestial Key with a Spirit they have a strong connection to, thus meaning they can never summon them again.
- The Power of Friendship: What finally convinces him to allow Leo back into the Celestial Spirit World. In a way he embodies this since breaking a Golden Key to summon him only works if the mage has a strong bond with the corresponding Spirit.
- Reasonable Authority Figure: He's the king of the Celestial Spirits and a benevolent leader. Seeing Lucy's conviction, he relents and pardons Leo, allowing him to return to the Spirit World.
- Red Eyes, Take Warning: A benevolent example.
- Spellblade: Can use his sword to create powerful magical attacks.
- Sword Beam: Can bring forth huge beams from slashing his sword, which is ridiculously destructive.
- Time Master: Time stops when he appears in the human world, except for those he addresses.
- This Is Unforgivable!: He was not happy with the sight of Lucy crying her heart out after having to summon him.
- Attack of the 50-Foot Whatever: He's even more monstrously huge in this form.
- Baleful Polymorph: His most dangerous ability by far involves turning his targets into harmless, immobile constellations.
- The Caligula: An absolute tyrant in this form. He's the real reason the Zodiac Spirits (sans Ophiuchus) wanted 'freedom.' He's become such a tyrant that he threatens to destroy the entire Celestial Spirit World, and they wanted to jump off the ship before it sinks, so to speak.
- Celestial Body: His body looks like a starry night sky.
- Eldritch Abomination: A huge humanoid monster with few an oddly shaped head and a mouth that's only present some of the time. It can transform people into inanimate constellations and open multiple black holes on its body.
- Greater-Scope Villain: Of the Eclipse Celestial Spirit arc.
- Omnicidal Maniac: Ophiuchus says he's going to inevitably destroy the Celestial Spirit World and everything in it, herself included. And she's okay with that.
- Xanatos Gambit:: He planted the whole "free from the master" plot into the other Eclipse Gold Keys just in order to progress his plot faster. It didn't matter if they completed the ritual or not, all succeeding in doing it would've just made them suffer in agony before they were turned back into constellations for him to absorb. They were doomed either way and the heroes closing their gates gave him exactly what he needed as well.
Gold Keys of the ZodiacThere are twelve different types of golden Zodiac keys, only one of each existing in the world. They can be used to summon one of the twelve spirits of the Zodiac. Incidentally, all the gold keys introduced in the series come into Lucy's possession.note

The Ram. She is a meek spirit who can use Wool Magic conjure fluffy pink clouds of wool in battle. Her master was the abusive Karen Lilica until Angel killed Karen and took her key as the spoils of battle. After Angel is defeated, Aries comes into Lucy's possession.
- Apologetic Attacker: She apologizes to her opponents before wool-bombing them (which doesn't even hurt them anyway).
- Apologizes a Lot: "I'm sorry" is her Catch Phrase.
- Badass Adorable: She really doesn't want to fight, but when she does she apologizes.
- Broken Bird: Her first two owners are extremely abusive to her. Karen wasn't above using her as a living shield, and even threatened to beat her. Angel, meanwhile, pits her against her dear friend Leo, knowing it would be hard on them both. Thankfully, she recovers nicely once she contracts Lucy.
- Catch Phrase: "Sumimasen" ("I'm sorry")
- Collared by Fashion: A big poofy one, but one nonetheless.
- D-Cup Distress: Her problem is that she gains too much unwanted attention.

- Impossibly-Low Neckline: She tries her best to keep it covered.
- Minidress of Power/Stripperiffic: Ironically, her outfit is very revealing.
- Mundane Made Awesome: Wool Magic.
- Rose-Haired Sweetie: She's far from cheerful, but she's still sweet and docile.
- Sensei-chan: In the second OVA.
- She's Got Legs: Thanks to her short dress.
- Ship Tease: Gets quite a bit with Leo/Loke.
- Shrinking Violet: Unfortunately, years of being abused by two horrible masters has made her scared of interacting with others.
- You Gotta Have Pink Hair: Her hair is pink.
- Zettai Ryouiki: Grade B.
- A-Cup Angst: Compared to her regular self. Juvia pointing out that the old Aries had a large chest naturally gets under her skin.
- Ambiguously Brown: Explicitly says she has a tan.
- Badass Driver: A street racer.
- Catch Phrase: "Can you dig it?"
- Chained by Fashion: Suddenly has chains in this form.

The Golden Bull. He possesses Herculean strength, but is constantly distracted by Lucy's breasts. He is one of the spirits owned by Lucy at the start of the story.
- A Load of Bull: He's a minotaur.
- An Axe to Grind: His weapon of choice, which he can use to block bullets.
- The Big Guy: Of the Zodiac Spirits. His main asset that he provides to his summoner is when the situation requires a physically mighty individual.
- Butt Monkey: Has won only one fight to date, and that was against a relatively low-power enemy. He does do decently against the Tartarus mooks though.
- Buxom Is Better: A huge believer of this trope.
- Chivalrous Pervert: His contract with Lucy essentially stipulates that as long as she stays hot, he'll gladly protect her sexy, sexy body. So, to that end, on one occasion he summons himself to block an attack that Lucy couldn't have otherwise dealt with.
- Distracted by the Sexy: His biggest downfall half the time.
- Incredibly Lame Pun: Is fond of these, usually involving cow-related things.
- Lovable Sex Maniac: He constantly compliments Lucy on her body.
- Overshadowed by Awesome: You can see from his appearance that he's pretty damn strong (a hulking bull-man wielding a huge axe), and the one time Lucy used him against some regular humans (thieves), he kicked their ass easily. So he's not really the weakling you would sometimes think he is - it's just that most opponents he get to face are nothing like regular humans.
- Red Baron: The Golden Bull.
- Took a Level in Badass: After the Time Skip, when Lucy learns how to use Combination Attacks between her spirits. Suddenly, Taurus is not so harmless.
- Underwear of Power: The only thing he wears is a pair of trunks.
- Verbal Tic: He regularly inserts "moo"-related puns into practically everything he says.
- Walking Shirtless Scene: As mentioned, he never wears any clothes but Underwear of Power.
- The Worf Effect: He is a physically powerful spirit, but usually loses.
- Badass in a Nice Suit: Sports this.
- Casual Danger Dialogue: Can fight while reading a book.
- Cool Mask: An iron bull mask
- Sophisticated as Hell: Much more refined in this form.
- Terrified of Germs: His Weaksauce Weakness, he had Elfman on the ropes in their battle. But once some of Elfman's sweat got on him, he started freaking out. Elfman defeats him by pinning him down and letting his sweat drip on him.
- Took a Level in Badass: Much more formidable in this form that he gave Natsu and Elfman trouble in their fights.

The Twins. They have Copy Magic to mimic the appearance of anyone and read their minds. They are Angel's signature spirits and follow her orders without question until Lucy proves to be a more caring master.
- Ditto Fighter: Copies the appearance and abilities of a person whose magic power is at the same level or lower than their summoner's.
- Early-Bird Cameo: They appeared on chapter cover pages well before their first real appearance.
- Heel–Face Turn: Due to their telepathy, they felt the love Lucy has for Celestial Spirits, which prompted them to fall to their knees and cry, as well as refuse to hurt Lucy.
- Necessary Drawback: They can only copy someone whose magic power is at the level of their summoner, meaning Lucy can't get Gemini to fight for her as monstrously powerful people like Erza or Laxus.
- Red Baron: The Twins.
- Telepathy: They can read the minds of anyone they copy, but forget once they lose that transformation.
- Tender Tears: Reading Lucy's mind deeply enough caused these and started their Heel–Face Turn.
- Troll: They love posing as Lucy nude and in front of everyone.
- Verbal Tic: "Piri piri"
- Voluntary Shapeshifting: They can copy up to two people at once. For every new transformation they acquire, they lose their oldest one.
- Wonder Twin Powers: They're two people. Both of them are required to use their magic.
- And Call Him "George"!: They are not good pet owners.
- Baleful Polymorph: Inflict this on their opponents.
- Brother–Sister Team: In their humanoid form, one can see their genders now.
- Creepy Twins: They appear much more humanoid in this form, and yet they have the most... bizarrely cheerful expressions.

- Hair Antennae: They both have two hair strands standing at the top of their heads, reminiscent of the antennae they had in their 'normal' forms.

- You Gotta Have Blue Hair: Matches the skin color of their 'normal' forms.

The Giant Crab. He is a hairstylist who wields a pair of scissors that can cut through virtually anything. Lucy inherits his key from her mother, and owns him by the time the story begins.
- Absurdly Sharp Blade: His scissors can slice through metal.
- Cool Shades : He's always seen wearing green-tinted sunglasses.
- Dual Wielding: Attacks by using his scissors to make opponents bald.
- Hair Reboot: Can do this with his magic, such as helping Wendy regrow her hair after she receives a Close-Call Haircut in the Tartaros arc.
- Mundane Utility: Lucy uses him as a hairdresser.
- Not Completely Useless: He gets to shine for one fight against Flare, who has Prehensile Hair.
- Red Baron: The Giant Crab.
- Shear Menace: Dual Wielding scissors.
- Verbal Tic: "-ebi"note
- In the dub, it's "baby", which makes a bit more sense, given that he's a hairdresser.
- Ambiguously Gay: Falls in love with Gray's dancing.
- Afro Asskicker: Suddenly sporting an afro.
- Cool Shades: Similar to the ones in his 'normal' form except they're black.
- Dance Battler: Challenges Gray to a dance off.

- Jive Turkey: Borders on Totally Radical at times.
Voiced by: Daisuke Kishio (JP), Eric Vale (EN)
A womanizing young man who is hardly ever seen outside the company of several young women. He tries to avoid Lucy at first because he is actually the celestial spirit Leo who was banished from the spirit world after causing the death of his previous master, but he has since been allowed to return thanks to Lucy, and now acts as one of her most trusted spirit partners. He draws magic from an enchanted ring called Regulus.
- Asskicking Equals Authority: As he's the most powerful Celestial Spirit we've seen (aside from the Celestial Spirit King, of course), it should come as no surprise that he's the leader of the Twelve Zodiac Spirits.
- The Atoner: Spent three years anticipating his own eventual demise to compensate for indirectly causing the death of his former owner before Lucy intervenes.
- Badass in a Nice Suit: In his spirit form.
- Big Damn Heroes: Has demonstrated the ability to break through his gate without Lucy having to summon him.
- Bishōnen: Top-ranked as Sorcerer Weekly's "Wizards You Want to Have As a Boyfriend" for a reason.
- Cat Boy: They can be kind of difficult to see, but he does have lion ears in his spirit form.
- Chick Magnet: He's often seen with girls drooling over him.
- Chivalrous Pervert: He may be a shameless flirt, but he's a legitimately nice guy.
- Cool Shades: Almost always seen wearing them.
- Determinator: Survived for three years in the human world with his own strength. To add perspective, Lucy initially believes that even one year was out of the question, and just one week outside the Celestial Spirit World is considered torture to his fellow Zodiac spirit, Aries. Even if he was The Atoner during those three years, that still takes a lot of willpower.
- Death Seeker: Lucy talks him out of it.
- Giving Someone the Pointer Finger: Gives it to Caprico during his You Shall Not Pass moment.
- Grand Theft Me: Gets his body momentarily snatched by Zoldeo in the Sirius Island arc. He's saved by Capricorn.
- It's All My Fault: Blames himself for the death of his previous owner, Karen Lillica, when it was her own arrogance that caused her fate. He was just standing up for himself and Aries.
- The Jail Bait Wait: While Lucy and Yuka were discussing about Wendy and Chelia, he comments "3 more years and they'll be in my scope" with a smirk on his face.
- King of Beasts The lion spirit and leader of the zodiac.
- Light 'em Up: Has this as his main power. Makes sense, since the Zodiac Leo is linked with the Sun.
- Loveable Sex Maniac: He's even introduced as "Fairy Tail's biggest ladies man"!
- Meaningful Name: "Regulus" is the brightest star in the Leo constellation.
- My God, What Have I Done?: All Leo wanted was for Karen to release his and Aries' contracts and made that point by refusing to be desummoned or obey her. He never wanted her to die as a result, even if it was because of her own actions.
- Not Quite the Right Thing: While well-intentioned, his decision to stay in the human world until Karen relinquishes her contracts with him and Aries results in her trying to go on a job with Leo unwilling to help her and her being unable to summon another spirit, leading to her death, Leo being banished from the Spirit World, and Aries' key ending up in Angel's hands.
- O.O.C. Is Serious Business: His breaking up with his many girlfriends and finally talking to Lucy all indicate that he didn't have long to live - until Lucy intervened.
- The Power of Love: He claims this to be the reason he can summon himself to help Lucy even when she doesn't call him.
- Red Baron: "The Lion".
- Ring of Power: Regulus. He also uses regular Ring Magic before becoming one of Lucy's spirits.
- Ship Tease: With Lucy and Aries.
- Shonen Hair: In his spirit form, while in his human form, he has normally short hair.
- Significant Anagram: The name Loke contains the letters "l" "e" and "o".
- Slasher Smile: Sports a rather terrifying one when possessed by Zoldeo.
- Spell My Name with an "S": Loki, Loke, Locke, among others.
- You Shall Not Pass: Pulls this on Capricorn in the Sirius Island arc.
- Arc Villain: Of the Eclipse Celestial Spirits Arc albeit Not Himself. Subverted later on, once we see The Reveal about Ophiuchus and the Celestial Spirit King...
- Casting a Shadow: Uses darkness, in sharp contrast to his 'normal' form.
- Combat Pragmatist: His 'dark flames' can cancel out Natsu's own flames. He takes advantage of this by copying Natsu's own moves, knowing that his attacks will be the ones that end up landing true because of this.
- Hoist by His Own Petard: Natsu later realizes that using his dark magic like this - i.e. making them materialize as 'dark flames' - means that he can eat them, earning a power-up.
- Disk One Final Boss: He thinks he's the mastermind behind the whole Eclipse plot but turns out he was being played himself before the true mastermind, the Eclipse Spirit King, reveals himself after he's defeated.
- Dark Is Evil: Uses Darkness-based Magic instead of his usual Light-based one.
- Drunk on the Dark Side: He won't shut up about 'darkness' while fighting Natsu. See Large Ham below.
- Evil Is Hammy: He really starts Chewing the Scenery while fighting Natsu.
- Evil Sounds Deep: In this form, Leo's voice is much deeper than in his 'normal' form.
- He-Man Woman Hater: In stark contrast with his usual Chivalrous Pervert persona.
- Kick the Dog: Flat out says that he doesn't care about Lucy's feelings towards 'Loke,' invoking That Man Is Dead just to taunt Natsu.
- Long-Haired Pretty Boy: His hair is much longer in this form.
- Slasher Smile: Delivers one to Natsu while Chewing the Scenery.
- Tin Tyrant: Wears an imposing golden suit of armor, instead of being a Badass in a Nice Suit.
- Unwitting Pawn: Heavily implied to have been this to Eclipse!Ophiuchus, who was serving the true Arc Villain of the Eclipse Celestial Spirit Arc all along.

The Maiden. She is a sadomasochistic spirit dressed as a maid who can use Earth Magic, specifically Diver, to burrow underground and manipulate earth. Originally owned by Duke Everlue, she makes a new contract with Lucy after the duke is arrested.
- Absolute Cleavage: In her Gonk form.
- Action Girl: Despite her odd tendencies, she's one of Lucy's top combat ready spirits and able to fight opponents like Bryo, the Bounty Hunter trio, and even Natsu.
- Catch Phrase: "Are you going to punish me?" / "Is it time for punishment?"
- Chained by Fashion: Just on her wrists.
- Cloud Cuckoo Lander: A rather quiet one, though.
- Covert Pervert: Though after a few arcs it's not so covert. Finally averted when she willingly shook her ass when the request wasn't even directed towards her, and she did it with a smile on her face.
- Disproportionate Retribution: Pretty much all the time she asks Lucy for punishment over anything. Even when she does things right.
- Fan Disservice: At least under ownership of Everlue.
- A Form You Are Comfortable With: She appears in whatever form she thinks will please her master most. In the case of Duke Everlue, it was a fat, really disgusting Old Maid. In the case of lucy, it's a more traditional Meido.
- Gonk: Under Duke Everlue, who thinks she looks attractive like that. With Lucy? Not so much.
- Heel–Face Turn: Though more My Master, Right or Wrong. She was under command of Duke Everlue and had to obey his orders. Once he was imprisoned, that voided her contract and she sought to be under the command of Lucy.
- Meido She wears a maid outfit in most of her appearances, but wears a swimsuit during the naval battle.
- House Fey: Worked as a maid before she joined Lucy.
- Marilyn Maneuver/Panty Shot: Happened while protecting Lucy from this trope. The anime didn't approve.

- Poor Communication Kills: In the Grand Magic Games arc, Team Natsu has three months to train until the tournament begins when Virgo invites them to spend a day in the Celestial Spirit World to party. It's only after the day is over that they learn one day in the spirit world equals three months in the human world.
- Red Baron: "The Maiden".
- Rose-Haired Sweetie: She's not at all cheery and sweet, but she's still polite and docile.
- Shipper on Deck: Ships Natsu/Lucy.
- This is a Drill: In the Brought Down to Normal Highschool AU.
- Too Kinky to Torture: She asks to be punished all the time. Heck the one time they did punish her, it's clear she's really enjoying it. Let's not forget there was a time when Lucy summoned her and she's summoned tied, Lucy freaked out and asked her who did that to her... Turns out she did it herself, it's her hobby when she has free time.
- Voluntary Shapeshifting: She adapts her looks to her owner's taste.
- You Gotta Have Pink Hair: She has pink hair.
- Zettai Ryouiki: Grade A.
- Absolute Cleavage: Just look at her picture.
- Ax-Crazy: Much more prone to violence in this form.
- Dominatrix: Fittingly enough.
- Having a Blast: Can now make her holes explode on command. She's practically a walking minefield.
- Interplay of Sex and Violence: She seems to enjoy inflicting pain on, and otherwise punishing, other people a little too much...
- Irony: She likes to dole out pain, but doesn't like to receive it. Go fig.
- Poke the Poodle: Attacks Lucy with watermelon and mayo when tickling her doesn't work.
- Putting on the Reich: Wears a more military outfit in this form.
- Villain Ball: She actually end up trapping Lucy in a spike pit and she just barely avoiding falling in with just a simple push to drop her futher.

- Whip It Good: To add with her dominatrix theme, she uses a whip as a weapon and more then enjoy hurting Lucy with it.
- You Gotta Have Pink Hair: She has pink hair in this form as well.

- Kick Chick: How she matches Yukino, a fellow user of this trope, in battle.
- Mask of Power: Compared to her normal form, this one covers the top half of her face.
- Red Eyes, Take Warning: In contrast to her original form's brown eyes, and she's definitely more Jerkassish.
- Sensual Spandex: As part of her Evil Costume Switch, and it's black to boot.

- Took a Level in Jerkass: Has no problem trying to kill Yukino, even taking joy in the idea of watching her fall to her death.
- You Gotta Have Blue Hair: Green, to be exact.

The Scorpion. He can use Sand Magic produce sandstorms from the tail-shaped cannon on his back. He is also Aquarius' boyfriend. He was initially owned by Angel until he decides Lucy would make a much better master.
- BFG: His main weapon, which is also his tail, shoots out sand.
- Catch Phrase: He seems very fond of the phrase "We are!" in the anime. In the manga he only says it when he's summoned, but in the anime he starts out every single sentence with this.
- The English dub replaces this with "Wicked!"
- Collared by Fashion: Wears a flower-shaped collar that is red and trimmed with gold around his neck.
- Dishing Out Dirt: He shoots huge streams of sand out of his tail.
- Early-Bird Cameo: He was mentioned quite often by Aquarius before his actual appearance, but never by name, instead just being referred to as "her boyfriend".
- Gratuitous English: "We are!" and "Yeah!"
- Heel–Face Turn: Like most spirits Lucy contracts that weren't hers at the start of the show.
- Morality Pet: To Aquarius.
- Multicolored Hair: Red and white.
- Official Couple: With Aquarius.
- Red Baron: "The Scorpion".
- Verbal Tic: He always says "We" instead of "I".
- Walking Shirtless Scene: He wears no shirt except for the collar around his neck.
- Calvinball: Essentially what his card game ends up devolving into since there's no specific rules to the game. Cana picks up on that and manages to win.
- Card Battle Game: Forces Cana into one despite her not knowing the rules on how to play.

- I Am the Trope: "I am the rules!"
- Multicolored Hair: Same as his 'normal' form.

The Archer. He is a master bowman in a horse costume who never misses his target. His key is given to Lucy by the natives of Galuna Island as a reward for rescuing them. His Eclipse form is a true centaur.
- Expressive Mask: The head part of his costume changes its expressions according to the situation.
- Genius Ditz/Literal-Minded: Possibly a combination of the two of these, or at least an innocent version of the first. When asked if he can produce fire (arrows) for Natsu, he stated that he can not. Only later does he realize that the issue at hand was if fire could be produced. Granted, it's partly a case of Poor Communication Kills, but it seems like a weird thing to distinguish.
- Is more justified, when you think of it as "Can you make fire at ALL", or "Can you make that ONE THING on fire."
- Improbable Aiming Skills: Sagittarius can aim his bow down and fire his projectiles at incredible speed, managing to block a bullet from Drake by intercepting it in midair with one of his arrows; a noteworthy feat, considering how, aside from reacting and aiming at the incoming threat, he had to pull his weapon's string in a split second to achieve this.
- Red Baron: "The Archer".
- Verbal Tic: "Moshi, moshi!" (Hello, hello)
- In the Funimation dub, he just says a multitude of weird-sounding greetings, goodbyes, and conjunctions. ("Yes sir-ee!" "See you later, alligator.")
- Affably Evil: Speaks like an old samurai
- Brick Joke: Before his normal form was revealed, Happy thought he look more like a proper centaur. Ironically his Eclipse form is just how he imagined him.
- Eyes Always Shut: His default expression.
- Fair-Play Villain: An honorable sort and fights Erza with no tricks, just direct skill of their abilities. When he loses, he takes it gracefully.
- I Gave My Word: When he challenges Erza to a three-match tournament and loses.
- Our Centaurs Are Different: He turns into a proper centaur in this form rather then a guy in a horse costume.
- Red Baron: "The Centaur".

- Bare Your Midriff: His suit while possessed by Zoldio.
- Beard of Evil: Initally played straight.
- Brutal Honesty: In the anime only, he seems reluctant to say something to Lucy, but she tells him not to worry about being honest. Unfortunately for her, he had quite a few issues with her weight when he was carrying her in his arms.
- Cool Shades: Was Sinister Shades before his turn.
- Evil Counterpart: To Leo at first.
- Grand Theft Me: Became the victim of this after Zoldio, his owner who was supposed to give his key to Lucy, went nuts and took over Capricorn's body, forcing him to stay in the human world for 17 years. Note that just three years are enough to nearly kill Leo, and a week would have been brutal torture for Aries, so it's hard to imagine the kind of pain he might have been in by the time he was freed.
- I Will Protect Her: His original intention all along was to be with and protect Lucy, because that was what her mother Layla had wished. Finally being able to do so was easily a CMOH for the series.
- The Mentor: Becomes one for Lucy after coming under her possession, helping her to learn more about her magic. In the anime, he also takes her being a Heartfilia very seriously, right down to cheerfully insisting she follow her heritage and become a proper lady.
- Red Baron: The Goat.
- The Stoic: Not when he's possessed by Zoldeo, though.
- Summon Magic: An interesting inversion of his nature as a celestial spirit; he's a spirit that is summoned by a person, and can in turn summon other people. Apparently he keeps them in some sort of pocket dimension until he needs them. Only time will tell if this is his actual power or if it was another side effect of Zoldeo possessing him.
- Undying Loyalty: To Layla Heartfilia, and then to her daughter Lucy. In fact, when Leo asks him if he will give his loyalty Lucy, he refuses, saying that he cannot give her something which has always belonged to her.
- Verbal Tic: He refers to himself as "Meh", which is the Japanese onomatopoeia for a goat's bleat.
- In the English manga, he opens many of his sentences with "Bah!", which is used to similar effect.
- Affably Evil: Is still nothing put polite in this form.
- Fair-Play Villain: Another honorable guy, he doesn't like violence and instead challenges Levy to a Quiz Game (albeit one that drop them into saws if either of them lose) with no tricks involved. He only ends up losing because he didn't think Levy would answer an embarrassing question about her love life that won her the game.
- Graceful Loser: He declares Levy to be the "Quiz Show Queen" after she defeats him and before she closes his gate.
- Hypocrite: He chides Levy for letting her impatience get the best of her, but when the quiz show host asks both contestants how they're feeling while they're hanging on for dear life, he impatiently demands that they get on with the final question.
- Petting Zoo People: He's actually a small taking goat rather then a humanoid one in this form.
- Quiz Show: The entire reason his "fight" with Levy is a quiz show is because he like quiz shows.

The Water Bearer. She is a powerful spirit who uses Water Magic through an urn filled with a limitless supply of water. She is one of the first spirits owned by Lucy, but hates her master's guts and often "accidentally" catches her master in her attacks along with her intended targets.
- Action Girl: Usually whenever Aquarius shows up, someone's about to get hurt. Badly.
- Anger Born of Worry: When Lucy exhausts herself summoning Aquarius while she already has Loke and Virgo's gates open, her first words are "You dumbass..."
- Bad Boss: She actually made Brandish call her "Master", and turned her so obedient that she would crawl and bark like a dog whenever Aquarius asked. After being reunited, Brandish, already as one the Spriggan 12 and that could shrink an island, still calls her master!
- The Bus Came Back: She comes back to save Lucy in Chapter 467, before being Put on a Bus once more.
- Cry Cute: While encouraging Lucy to snap her key, she claims that she's always hated her, and won't miss her. Once Lucy actually does the deed, however, she finds herself tearing up at their imminent parting.
- Disproportionate Retribution: Spanking Lucy for losing her keys the second time despite the fact that she was forced to drop them when Juvia trapped her in a water lock as she was trying to defend herself.
- Elemental Baggage: One of the few aversions in the series. Lucy can't summon her without an existing body of water, though what qualifies as a body of water seems to very based on needs of the plot.
- Expy: Of Mashima's oneshot Fairy Tale, Undine who is the mother of Lucy's Expy of the same oneshot, Elle.
- Freudian Excuse: Her attitude towards Lucy was largely because in the past she would frequently summon her because she didn't have any friends and always viewed her as a crybaby even long after she grew out of it. Nearly borders on Disproportionate Retribution in a few cases if not for the fact she does show she cares, just has a really hard time showing it.
- Heroic Sacrifice: Tells Lucy to summon the Spirit King by breaking her Key. Although this doesn't mean Aquarius is going to die, Lucy will never be able to summon her again. Remember, there is only ONE gold key for each spirit
- Hypocritical Humor: Her calling Brandish a rebellious little bitch is actually hilarious considering that Aquarius herself most of the time either ignores the orders given by Lucy, her own master, will even attack Lucy if she somehow annoys her or even abandon her in the middle of a fight. Her calling Brandish this is a case of the pottle calling the kettle black.
- Inconvenient Summons: Tends to act like any summons is this.
- Jerk with a Heart of Gold: She's ill-tempered, rude and doesn't care that her attacks hurt Lucy and her allies. However, moments before Lucy breaks her Key to summon the Spirit King on her suggestion, Aquarius admits that deep down she really cared for Lucy.
- The Load: As fierce a fighter she is, there are moments where she just flat out abandons Lucy when she's really needed, such as the battle with Angel in the Nirvana arc (leaving when Scorpio was summoned and revealing he's her boyfriend), and during the underwater battle in the Grand Magic Games arc (counters one attack before splitting). In both cases, Lucy winds up in real danger as a result.
- Making a Splash: Just look at her name.
- Mama Bear: During the Tartaros arc, when Lucy opens three gates and is at the mercy of Jackal, she becomes fiercely protective of her. Clutching her closely and letting no one come near her despite being stabbed in the shoulder and knowing she's no match for the demons of tartaros.
- Nice Job Breaking It, Hero!: When Brandish was a kid, Aquarius treated her nearly like a dog. Brandish, as one of the Spriggan 12, treats Marin the same way. Marin, unlike Brandish, eventually had enough and tried to choke her to death.
- Odd Friendship: With Juvia.
- Official Couple: With Scorpio.
- Oh, Crap!: When she realizes Hughes can wrest control of water from her. Again when Torafuzar easily swims through it to attack her.
- O.O.C. Is Serious Business: She'll usually abandon Lucy at the quickest opportunity, but during the Tartaros arc, when Lucy's life is in clear danger without any of her guild mates to help her, the worst she does to Lucy is call her an idiot for overexerting her magic power to summon her, and she is fiercely protective of her against her opponents.
- Pet the Dog: In the anime only, she cries out for Lucy's safety in the Edolas arc when her master is attacked and she herself is powerless.
- Also, she was among the rest of Lucy's spirits who agreed with her that Leo shouldn't sacrifice his life for a reason they believe not to be right.
- She also tells Lucy to summon the Spirit King by breaking her Key.
- At the start of the anime only Eclipse Celestial Spirit Arc. She's temperamental as always when Lucy tries to grant her a wish for her hard work and typically her wish is to see Lucy embarrassed. First by making Yukino and her act out a play, then as usual attacking her with water which leaves Lucy hung on a tree "like laundry". She does however get her down and dry her off afterwards and they spend the night watching the stars together.
- Put on a Bus: After a brief reappearance in Chapter 467, she states that her Key was reappeared somewhere in the world, but she can't say where. Lucy vows to find it after the war with Albareth.
- Rapunzel Hair: Her long, light blue hair reaches up to her waist.
- Red Baron: The Water Bearer.
- Running Gag: Abandons Lucy in the middle of a battle to go on a date with her boyfriend.
- Tsundere: She acts hot-tempered and bitchy to everyone, especially Lucy, her dere side only shows up around her boyfriend. Later, right before Lucy breaks her Key, Aquarius claims she always hated Lucy for being such a naive, crybaby little brat, but admits to herself that she did care about Lucy and never being able to see her again makes her feel sad.
- Undying Loyalty: To Layla Heartfilia. The main reason she was always so hostile to Lucy was because she wasn't Layla despite the fact that Lucy's her daughter.
- Unexpected Character: Despite her key being broken, she somehow reappears at the end of 467 to stop Brandish from suffocating Lucy to death.
- Unfriendly Fire: Not just because she's a Jerkass around Lucy; her power is inherently just so destructive. In fact, this is used to Lucy's advantage when Aquarius is being controlled by Sherry.
- You Gotta Have Blue Hair: She has light blue hair.
- Affably Evil: She might be an antagonist, but she is a quite cheerful and nice girl that even invited Wendy and Carla to eat ice cream. It is quite a shame she couldn´t stay like that.
- Bratty Half-Pint: Changed into a little girl in this form.
- Cute and Psycho: Evil, yet incredibly adorable.
- Friendly Enemy: Eventually develops this with Wendy.
- Go-Karting with Bowser: Has no problems playing with Wendy and Carla in an amusement park when they come after her, even sharing ice cream with them during a mid-fight break. Of course, her problem is that she can't quite see the difference between "playing" and "fighting".
- Irony: She sounds a tad nicer in this form, though still one hundred percent with breaking away from their owners.
- Making a Splash: A given only she has much better control of water in this form rather then the tidal wave throwing she usually does. To the point she can send out smaller streams of water and even make a water dragon to chase her targets.
- Mythology Gag: Not only is she turned into a child in this form, but one of her main attacks is creating a water dragon. She fights against Wendy, who was originally planned to be the Water Dragon Slayer.
The mother is voiced by: Kanami Satō (JP), Stephanie Young (EN)
The son is voiced by: Shohei Kajikawa (JP), Justin Pate (EN)
The Paired Fish. The two attack their target in pairs. They seem like fish at first, but their true form is a mother and her child. They are owned by Yukino Agria.
- Absolute Cleavage: The mother, combined with Cleavage Window.
- Action Mom: The mother.
- Ambiguously Brown: The son in human form.
- Badass Family: A mother and son team
- Bishōnen: The son fish in human form.
- Dark-Skinned Blonde: The son, again.
- Kick Chick: The mother.
- Irony: While they are "fishes", they are weaker in water.
- Let's Get Dangerous!: When summoned in their human forms, they know it's time to fight hard.
- Making a Splash: Both being fish helps.
- Prongs of Poseidon: The son in human form.
- Red Baron: The Paired Fish.
- Tag Team Twins: They're two giant fish that both fight and transform together. In human forms, they're actually mother and son.
- Voluntary Shapeshifting: They can shift between a fish-like and humanoid form at will.
- Walking Shirtless Scene: The son.
- Weaksauce Weakness: Ironically enough, they can't fight in water, and revert back to being small fish.
- You Gotta Have Blue Hair: The mother has dark blue hair in her human form.
- Anti-Magic: The son has this ability as he's able to cancel out Natsu's fire attacks.
- Big Eater: The mother can seemingly eat any attack! Even fire!
- Consummate Liar: The son does this alot, claiming he'll do an action then responding "just kidding" and doing the opposite.
- Fish People: A lot more played straight in this form. The son now looks like a merman and the mother is a flying shark.
- Flying Seafood Special: The mother has the ability to fly in the air.
- Momma's Boy: The son though he acts like he doesn't need her most of the time.
- Outgambitted: They think they managed to steal the keys that close their gates away from the heroes, however it turned out to be a fake as the real keys were hidden during an earlier scuffle.
- No Sell: Ironically water now has no effect on them.
- Sand is Water: Sort of, the mother can generate water and swim through rock surfaces.
- Threatening Shark: The mother is now a huge shark.
- Sizeshifter: The mother has the ability to change her size.
- Verbal Tic: The son's constant "Zruh"
The Serpent Bearer. This massive, mechanical snake-like spirit is regarded as a thirteenth Zodiac spirit. It is owned by Yukino as her most powerful spirit.
- Attack of the 50-Foot Whatever: A giant black snake with metal body parts? It counts.
- Non-Indicative Name: In a manner of speaking. In astrology, Ophiuchus is the name of the man who holds the Serpent, whose name is Serpens. Being that he's the Serpent Bearer, it's a little odd that he's portrayed as being the serpent in question. The Eclipse Spirits arc answers that question by revealing her Eclipse form is very much human.
- Red Baron: "The Serpent Bearer".
- The Sixth Ranger: The thirteenth of the twelve Zodiac spirits.
- 13 Is Unlucky: Yukino describes it as an unlucky spirit and it's the thirteen of the Zodiac keys.
- The Worf Effect: Presumably is more powerful than the other 12 spirits and likely second only to the Celestial Spirit King himself, but gets cut down by Kagura before it can show its true power.

- Altum Videtur: "Omnia... Magna... Stella... Rex Prae..."Translation
- Attack Its Weak Point: Subverted. Yes, getting punched there by Natsu did hurt, but it was more of a Wounded Gazelle Gambit to get Natsu to start warping Astral Spiritys to aid Lucy and Yukino, resulting in their gates being closed, which was exactly what she wanted.
- Attack Drone: Summons some form of robotic Attack Drones right when she says she's going to 'get serious.'
- Bishonen Line: Just contrast her humanoid (and frankly, very attractive) Eclipse form with her downright monstrous, gigantic 'true' form. She kicked Natsu and Wendy's ass in this form, but her true form was subject to a One-Hit Kill by Kagura.
- Blind Obedience: She states flat-out that she doesn't care if the Eclipse Celestial Spirit King kills her, as long as it is what he truly desires.
- The Chessmaster: Holy crap is she a Manipulative Bitch! She was playing everyone, from her fellow Celestial Spirits to the heroes, from the very beginning of the Filler Arc, in order to serve her true master, the Eclipse Celestial Spirit King. See Xanatos Gambit.
- Cute and Psycho: To contrast her main form, which is a huge snake that is taken seriously by everyone.
- Cute Little Fangs: Going along with her Cute and Psycho and to remind us her true form is a giant snake.
- Dark Action Girl: She mopped the floor with Natsu and Wendy.
- Deadly Doctor: She represents the medical aspect of snakes.
- Depraved Dentist: At one point.
- Does This Remind You of Anything?: What she says right before shoving a gigantic tongue depressor into Natsu's mouth... yeah, let's keep this PG-13.
- The Dragon: Appears to serve this role to Dark Leo, but it's subverted. She's The Dragon, alright. Just not to Leo.
- Eldritch Abomination: What she later proves to be. Her Eclipse Form isn't just a Deadly Doctor; it's the entire realm of Astral Spirytus, and she can control it accordingly. See also One-Winged Angel.
- Expy: Snakes? Hospital Hottie? Greenish-blonde hair? Master of playing both sides of a conflict? Medusa, anyone?
- Just Toying with Them: Her first bout with Natsu's group was simply her stalling for time to allow Leo to go set up the ritual.
- Healing Factor: Arcadios chops her giant snake's Multi Purpose Tongue off. It grows back not even a second later.
- The Heavy: While the Eclipse Spirit King is the true antagonist of the arc, he lacks any real focus until the end. It is Ophiuchus who drives the main conflict by manipulating both the heroes and the other Eclipse spirits through Leo, and while she is defeated, ultimately it all went according to her plans.
- Hospital Hottie: Justified that the constellation is revered by medical professionals.
- Leaning on the Fourth Wall: Takes out a chart to explain her constellation and why she is a nurse.
- Let's Get Dangerous!/Obfuscating Insanity: When she goes One-Winged Angel, she drops all pretexts of being Cute and Psycho and becomes downright freaking terrifying.
- Make Me Wanna Shout: With a magic stethoscope.
- Male Gaze: Thanks to her Minidress of Power, the anime takes no small amount of time focusing on her butt.
- The Man Behind the Man: To Leo, for the Celestial Spirit King.
- Minidress of Power: One that looks like a doctor's labcoat, but is short enough to show that She's Got Legs.
- Musical Assassin: In her true form, she uses an ocarina as her main weapon, which can allow her to control anything or anyone in her line of sight.
- One-Winged Angel: It's not just that gigantic, thorn-covered snake. She is literally Astral Spirytus. As in, the realm.
- Power Makes Your Hair Grow: When she merges with the giant snake, her hair becomes noticeably longer.
- Reptiles Are Abhorrent: And frankly, fucking scary in her case.
- Scaled Up: Once Leo tries the ritual again, she suddenly appears in a merged version of her snake form.
- Samus Is a Girl: Turns out to be female in her Eclipse form. Color us shocked...
- Shout-Out: When did a Celestial Spirit visit the land of 'Hyrule'?
- Verbal Tic: 'Denasu.' It's an act.
- Xanatos Gambit: Masterfully executed. She knew the heroes were going to try to force the Zodiac Spirits' gate closed. She actually needed this, because forcing their gate closed sends them right back to the Celestial Spirit World, with the Celestial Spirit King. If Liberum had been allowed to succeed as Leo wanted, the Celestial Spirit King would have been virtually unchallenged to continue his reign of terror. Either way, he won, and Ophiuchus kept both the heroes and the other spirits in the dark the whole time.
Silver KeysSpirits who are summoned using common silver keys are not typically summoned for combat purposes, but are rather done for casual reasons.
Voiced by: Saori Goto (JP), Majken Bullard (Season 1; EN), Monica Rial (Season 2 onwards; EN)
The Canis Minor. Nikora is a common breed of celestial spirit, and the minimal amount of magic power it takes to summon it makes it an ideal pet. Lucy owns her own Nikora, which she names Plue.
- Call a Smeerp a "Rabbit": He looks like a pretty funny dog to us (then again, the constellation of Canis Minor doesn't look much like a dog, either).
- Fake Cross Over/Mythology Gag: From Rave Master, Hiro Mashima's other work.
- Spell My Name with an "S": Nikora/Nicola
- Team Pet: Moreso than Happy, who is at least The Smart Guy.
- The Unintelligible: Natsu can understand him perfectly, for some reason.

The Clock. He is a talking grandfather clock who Lucy tends to summon to use as shelter from hazardous environments.
- Big Damn Heroes: Saves Lucy from the collapsing Nirvana and from being sucked through the Anima, and Wendy from one of Hades's attacks. Does it yet again when saving Arcadios from lava. He even manages to save Natsu, Lucy and happy from being send to another dimension by Jacob Lessio of the Spriggan Twelve. This is basically Horologium's hat.
- Chekhov's Gunman: His ability to conceal people inside his body comes in handy.
- Nigh Invulnerable: Moreso than the other spirits, since he is specifically a defensive spirit that can hide others inside of his body. He has been shown to protect people from inter-dimensional magic, falling rocks, a One-Hit KO spell, lava, and cold weather.
- Red Baron: "The Clock".
- Verbal Tic: "...he/she says." Justified in that the inside of his body is totally soundproof, and he must relay the words of whatever people inside him say to everyone else.
- The English dub takes this a step further: he not only says what people say, but how they say it, such as "...he/she yells furiously" or "...he/she asks tearfully," just to make good with the lip-locking.
Voiced by: Megumi Nakajima (JP), Kristin Sutton (EN)
The Lyre. She is typically summoned for her phenomenal singing voice.
- Blush Sticker: Her cheeks always have round pink blush marks.
- Cat Smile: Has this as her default expression.
- The Empath: Her songs reflect what those around her feel at the given moment.
- Genius Ditz: She's surprisingly smart given her rather eccentric behavior, though she's mostly used as an Exposition Dump.
- Genki Girl: A very happy and energetic spirit.
- Harp of Femininity: She is named after the celestial harp.
- Red Baron: "The Lyre".
Voiced by: Masafumi Kimura (JP), Bill Flynn (EN)
The Southern Cross. This cross-shaped spirit has an encyclopedic knowledge of celestial spirits and their owners, which he searches for by sleeping.
- Cool Old Guy: Always helpful to Lucy.
- Eyes Always Shut: Unless he screams.
- Jump Scare: In-Universe; anyone besides Lucy gets scared silly when Crux finds something.
- Red Baron: "The Southern Cross".
- The Scream: When he finds what he's looking for, he awakens with a startling scream.
- Senior Sleep Cycle: Only Lucy can tell when he's looking for information or is actually asleep.
- Snot Bubble: The only way to tell if he is asleep or thinking is to look for the snot bubble.
The Chisel. It is one of Angel's contracted spirits that acts more like a weapon than a sentient being, able to switch modes between a sword and cannon.
- BFG/BFS: Caelum is both and can switch to one at the user's will.
- Frickin' Laser Beams: In it's cannon form, Caelum can launch powerful blasts of green energy, one of which was shown to incapacitate both Loke and Aries and send them back to the Celestial Spirit World in one shot.
- Red Baron: "The Chisel".
- What Happened to the Mouse?: In the manga Aries, Scorpio and Gemini are all revealed to have joined Lucy after Angel was imprisoned. But Caelum's fate is unknown. In the anime it returned in the Key of the Starry Sky Arc under Katja's control though it's not revealed how she got its key. Supposedly it's just one of many types like Nikola is.
The Compass. It is a penguin with a compass on its head.
- Corner of Woe: It and Lucy try to be useful for Team Natsu in the "Sky Labyrinth" challenge of the Grand Magic Games. Then Erza tells them she already has her own compass.
- Red Baron: "The Compass".
- Throw the Dog a Bone: The anime thoroughly expands the challenge by adding an area that screws with Erza's compass, giving Pyxis the chance to show why it's more useful than any ordinary compass with its superior sense of direction.
- What Kind of Lame Power Is Heart, Anyway?: It can tell any direction. Just like any regular compass can.
The Bear Cub. One of of the few combat silver keys. Only appears in the anime.
