Loke

Loke "Leo the Lion" is a member of Fairy Tail who was revealed to be a Celestial Spirit, one of the Zodiac Spirits.

Appearance
Before Loke revealed himself to be a Celestial Spirit, he wore his strawberry blonde hair short and his attire consisted of a green jacket with a fluffy white collar, a light red Hawaiian-like shirt and black trousers. When Loke resumes his job as a Celestial Spirit, he sports thicker and larger hair with several earrings in each ear. His attire is also more formal: a black suit with a lightly colored shirt and a zebra-striped tie. (Red in the anime). While he was on Tenrou Island, Loke wears his hair style as it was during his time in Fairy Tail, though he changes it back during his fight with Caprico. Loke also sported light blue sunglasses, which he wore in both his time in Fairy Tail and as a Celestial Spirit. Loke's Fairy Tail member stamp is located on his back. He is known to be hot and attractive.

Personality
Loke is very flirtatious with attractive women, being top ranked as the "Mage you want to have as your boyfriend", according to Weekly Sorcerer magazine. When he tried flirting with Erza Scarlet, he nearly got himself killed. Early during his time in Fairy Tail, a troupe of girlfriends were consistently around him.

Whilst being amorous, he does not take kindly to those who abuse or take advantage of women. He is very loyal to his friends; for example, he stayed in the human world for a long period of time, despite how harmful it is to Celestial Spirits, in order to free his friend Aries from Karen's tyrannical treatment.

History
Loke (Leo the Lion) was contracted to the Celestial Spirit Mage Karen Lilica. Karen was an abusive master to Aries, often mistreating or directly hurting her. One time, she even used her as a shield against attacks. Just as she was about to sentence Aries to seven days' imprisonment in the Human World, which is thought to be fatal to Celestial Spirits, Leo appeared in her place. Due to her wicked and abusive nature, Loke demanded that the pacts with him and Aries be removed and that he would stay in the humans' world until she did so, easily resisting Karen's attempts of forced closure of his gate.

By staying in the human world, Loke prevented Karen from summoning any other spirits for combat, thus taking away her ability to perform jobs. Karen made several attempts to persuade, beg, trick, and coerce Leo into returning to the Spirit World, all of which he refused, much to Karen's anger.

After three months, Leo became able to endure the pain of being in the Human World. Believing that Karen had been punished enough, he decided he could forgive her and if Karen abused Aries again, he would defend his friend. However, he learned soon that Karen, in desperation, had attempted to complete a job without her spirits and had been killed by another Celestial Spirit mage. For violating his contract with Karen and causing her death, he was forbidden to return to the Celestial Spirit World. Soon after, Leo disguised himself as a human named Loke, and joined the Fairy Tail Guild as a Mage.

Macao arc
Loke is first introduced with some women. When Natsu ends up brewing up a fight, he comments that it's noisy, and tells his women he'd join the fight, which makes Lucy say he corrupted his iMage. When Gray Fullbuster asks to borrow Lucy's underwear, Loke comments that they have no grace and takes Lucy to a different area. He is about to use his Magic to end the fight like everyone else, but he is stopped by the guild master Makarov. Makarov also reads off charges against Loke for flirting with Council Member Elder Rage's granddaughter; a talent agency charged them for damages as well.

Lullaby arc
He is seen at the beginning with Gray, and also flirts with Lucy yet again. However, he realizes that she is a Celestial Spirit Mage and runs away, Mirajane stating that he must of had a bad experience with one in the past. He runs back to the guild to inform Natsu Dragneel and Gray that Erza is back. Mirajane also says that Loke had tried flirting with Erza and had nearly got himself killed. He's seen standing away from Erza, sheepishly murmuring that he might go home.

Phantom Lord arc
When Makarov announces war upon Phantom Lord due to the attacks on Levy McGarden, Jet and Droy, Loke is at the front of the fray when they smash into Phantom Lord's guild, and attacks alongside Cana Alberona.

Due to the shock of Makarov losing his Magical power, and thus, their dramatic decrease in strength, they are forced to return to the guild. However, Natsu was able to retrieve Lucy and as she is brought to tears by something he said, Loke watches from afar with a worried expression. Without warning, the behemoth six-legged Phantom Lord guild appears and fires its extremely powerful Jupiter cannon at the guild. Erza, using her Herculean Armour, just manages to stop the attack, giving them a fifteen minute window to destroy the cannon before it is reloaded. Natsu volunteers to destroy it as Cana affirms that she and Loke will hold the front-line against Jose Porla's shades.

When the Jupiter cannon and then the Abyss Break is stopped, Loke rushes to Lucy's hiding place to find Lucy missing and Reedus Jonah defeated. He had a feeling this would happen and tearfully blames himself.

At the end, with Phantom Lord finally defeated, Loke searches for and finds Lucy's keys, and gives them to Gray, asking if he could return them. He seems oddly nervous and when Gray asks if he wanted to come to Lucy's house, he refuses, saying that he had had a bad experience with Celestial Spirit Mages.

Loke arc
The gang first meets Loke upon completing a mission in Balsam Town. They wander over to find out that Loke had a mission in the area (before running away from Lucy). When Lucy goes outside with Plue and Happy because the others were engaged in a serious pillow fight, she is assaulted by bandits; however, she is saved by Loke. Loke then states that his job was to capture them. As thanks for saving her and to chat, they go to a local bar together, with Loke still being afraid of her. Lucy, thinking that their conversation is completed, gets up to leave, but Loke stops her and then hugs her, announcing that he will die soon. Realizing that he didn't want to get her involved, he then states that he was joking and that it was just one of his pick-up lines.

This makes Lucy so upset that she slaps him and storms off. The next day, Loke's girlfriends are at the guild, upset that he had broken up with them and are looking for him, confronting Lucy when Mirajane calls out to Lucy for help, which results in them thinking that Lucy is the reason Loke left them. Lucy is suspicious of what he said the night before, and summons Crux to do a search on him, finding out about Loke's history and former owner Karen Lilica. Gray then bursts into Lucy's room, saying that Loke had quit the guild and disappeared. Lucy decides to go look as well, thinking she might know where he is.

Lucy goes to the area Loke is at (Karen's grave). She reveals she knows Loke is the Celestial Spirit, Leo the Lion. Lucy asks why Loke is still in the desperate human world. Loke says he's stuck and has been for three years, but is now losing his ability to stay in Earthland much longer. Loke reveals he cannot go back lonely because he killed his master, Karen Lilica. After telling Lucy his past, Loke finally starts to lose his grip and tells Lucy goodbye and asks her to tell Fairy Tail that he's sorry. She tries to save him by opening his gate so he can live back in the spirit world. Loke begs her to stop and says that he deserves to die, as it is the rules. Lucy Sneaker, however, shouts that she would change the rules and tries to forcefully put Loke back by using her spirit energy. Noticing this, the Celestial Spirit King appears himself.

He explains that although Loke did not directly kill Karen Walker, it was still his actions that caused her death. In an attempt to convince the Spirit King, Lucy summons all of her current Gold and Silver Keys, stating that saving your friends is not a sin. It amazes Loke that she could summon this much at once, since it requires a huge amount of energy, although they quickly disappear. The Celestial Spirit King, seeing Lucy's resolve to save her friend, allows Loke to return to the spirit world since he realizes Loke only disobeyed Karen for the sake of Aries. Loke says farewell, and as thanks for saving him, gives her his key.

Tower of Heaven arc
Events take place in Tower of Heaven Arc in the manga but Loke Arc in the anime.

Loke reappears at the guild's makeshift bar, surprising Natsu, Happy and Gray with the revelation that he is a Celestial Spirit who looks human, much like Virgo. When asked what spirit he is, Lucy reveals that Loke is Leo the Lion, much to Happy's delight to the point that he drooled on his shoulder. Getting a bit too flirtatious with Lucy, she nearly closes his gate, but he stops, saying that he has something to give them first: tickets to a resort hotel.

Fighting Festival arc
Before Lucy is finished off by Bickslow's strongest attack, Baryon Formation, Loke rushes in without being called and saves her before she's hit by the attack. Loke appears to have a totally different look, with his hair extended into a lion's mane and his outfit of black clothes; Loke states he has come to fulfill his promise with Lucy.

Bickslow mentions that he always had a feeling Loke was a Celestial Spirit; Loke responds that hurting his owner is something he can never forgive. Bickslow laughs and reminds Loke that he's never once beaten him in a fight. Loke orders Lucy to stay back, however, Lucy refuses and states that Celestial Spirits aren't shields and that she would fight together with Loke. Happy whispers that "they're a cute couple", making Lucy shout at him.

Eventually, Lucy entangles Bickslow with her whip and Loke finishes him off with his Regulus Impact attack, knocking Bickslow out in one hit; he then makes a light saying "I Love Lucy" for Lucy to which Happy whispers "He llllikes you". After Lucy falls down, feeling the affects of summoning two Ecliptic Zodiac keys, Loke returns her keys and says that he will always be there when she needs him. He later makes a brief appearance at the guild with Lucy as everyone celebrates and recovers.

Oración Seis arc
Loke makes his appearance after Lucy summons him in a desperate attempt to defeat Angel. However, Angel counters this by summoning his friend Aries. Lucy, not wanting them to fight, tries to close his door, but Loke refuses because it's his duty to serve his master, saying that he has to fight Aries. Aries agrees, and says she has to fight her master's enemy.

Angel is surprised they're fighting, and says that with Loke as the opponent, Aries won't stand a chance. Angel summons Caelum, a Celestial Spirit that takes the form of a cannon, and shoots both Aries and Loke through the stomach. Loke tells Lucy he's sorry as both he and Aries fade away to the Celestial realm to heal.

Edolas arc
When Lucy tries to summon Leo to do battle with some soldiers, Virgo appears instead, because Loke was out on a date. After this, during the battle with the Edolas Royal Army, Lucy summons him again, and they begin fighting after he apologies for being late. While they are fighting back with all their strength, they are almost defeated when Lucy falls to the ground, and Gray and Loke are flung away by the Legion reinforcements. When the Fairy Tail members from Edolas come to help, Loke is clearly happy to see the two Lucy's (his eyes were heart shaped, and he had an open mouth, and a drool smile).

S-Class Trial arc
Loke appears with his old hairstyle and tells Lucy that he must suspend his agreement of being her spirit during the trial, as he'll be Gray's partner. He assures Lucy that he is sustaining his presence with his own Magic, so her own Magic will be unaffected, save that the suspended contract means she will be unable to summon him. When Elfman asks him how he's still considered a Fairy Tail member, Loke reveals he still has his Fairy Tail mark on his back, and he'll fight to make Gray an S-Class Mage. When the ship they were on arrives at Tenrou Island, both and he and Gray are stuck on the ship due to Freed's runes, but are released along with the other contenders five minutes later. Later, they enter a battle route leading to Mest and Wendy. Amazingly, they manage to defeat both of them easily. While moving on, Gray ponders on Mest's strength and asks Loke who his partner was last year; to both their frustration, Loke realizes that they cannot recall any memories about Mest and it appears hazy to both of them. Loke and Gray are interrupted from their thoughts after seeing the people who passed the first round of the trial. They later converge with those who passed the first part of the exam, along with Makarov, who informs them of the 2nd part of the exam - to find the resting place of Fairy Tail's first Guildmaster on Tenrou Island. He and Gray are later seen following Cana and Lucy discreetly, with the latter appearing to have some sort of epiphany concerning the location of Mavis Vermillion's grave. They opt to have the two girls lead them to their target, with Gray telling Loke that the second part of the exam was also about 'greed'.

Later, the two of them are seen gazing up into the sky as the signal flare that Erza fired illuminates the atmosphere above Tenrou Island, as a sign to get ready for battle. Gray stops Loke from telling Lucy and Cana that they "intentionally followed them", and the two suggest for the four of them to head back to the emergency meeting spot, to which Cana and Lucy hesitantly comply. Along the way, they see numerous bubbles in the air, which Grimoire Heart members promptly come out of to confront the group. The four then easily dispatch most of the members in their vicinity. The remaining members suddenly vanish, and Caprico reveals himself, saying that he alone would suffice in taking them down. Loke shows surprise at seeing him. As the fight begins, Loke almost immediately takes a kick to the head by Caprico.

After realizing that there are 6 other purgatory members on the island besides Caprico, Loke tells them to head off and face the other 6 members. He also explains that the reason he should fight alone against him is because of his Magic, which weakens humans. When he transforms back to his original form, he reveals Caprico's identity as the Celestial Spirit Capricorn the Goat, which surprises Cana and Gray, and makes Lucy somewhat sad. After he tells Lucy to leave, he enters his battle with Capricorn, while asking how long it's been since his disappearance. Although he manages to get a powerful attack in, Capricorn manages to surprise him with an ability he didn't originally had since he is no longer the summoned, but the summoner. Loke receives a major wound from Capricorn's summoned subordinate, San Jao Shin.

Capricorn reveals that he knew that Loke asked for a one on one fight in order to protect Lucy, his summoner. Loke recalls Lucy's parting words, and Caprico is reminded of Layla Heartfilia's last words to him. When Caprico becomes enraged, Loke realizes that Caprico has become aware of the fact that Lucy is the daughter to Layla Heartfilia. Caprico tries to kill Lucy with his human subordinates, but Loke stops him. Loke states, that according to Crux, Caprico had made a contract with Layla 20 years before now, leading him to believe that Caprico should now belong to Lucy. "Caprico" then reveals that he is actually a Human spirit in Caprico's body, who used Human Subordination Magic on a Celestial Spirit and by that, broke Taboo, which fused him in Caprico. After that, he reveals that he intends to use same on Loke, because Caprico's body was seriously injured; he succesfully does fuse. However, before hand, Loke gave his Regulus power to Capricorn so he could help him. Together, the Celestial Spirits defeat Zoldeo and return to their world to heal.
