One such character in the series is the Celestial Spirit King, a transcendent being that rules over the world of celestial beings. Despite making only a few appearances throughoutFairy Tail’sruntime, the Celestial being has played a key role in moving the plot forward, and that too without exploiting the concept of plot armor.

Although little is revealed about this mysterious character, the show has hinted towards the King’s personality and magical prowess a few times, with more details being revealed during the Tartaros arc, where he played a pivotal role in allowing the storyline to progress forward.Fairy Tailrarely sheds lighton the Spirit King due to his revered place within the show, however, connecting pieces from several of the anime’s arcs has disclosed enough information to understand what this godly being entails.

Celestial Spirit King – A Spirit Without a Key

The Celestial Spirit King is undoubtedly one of the strongest characters in all ofFairy Tail, making the Fairy Tail guild members seem quite trivial in comparison. However,Hiro Mashima, the show’s creator, has done a surprisingly good job at barring this character from becoming an overwhelming power creep in the series.

Unlike other spirits from the Celestial Spirit World, the Spirit King does not have a Gate Key – a magic item that channels the user’s power to summon celestial beings, meaning he cannot be summoned at will.

Lacking a Gate Key does not necessarily mean that it’s impossible to summon the Celestial Spirit King, however, doing so requires a grave sacrifice that only a few can qualify for. This allowsFairy Tailto present a balanced narrative of the show, one wheremagical beings don’t run rampantwith their inexplicable power.

Summoning the Celestial Spirit King

Despite not having a celestial key, the Celestial Spirit King can still be summoned, but to achieve such a feat, the wizard must be adept in Celestial SpiritMagic with considerable prowess. There are also a few conditions that need to be met before a wizard can summon forth the Spirit King.

The first condition is that the celestial mage must be able to summon three spirits at once, an undertaking only a few can achieve. Second, a Golden Zodiac Key must be sacrificed, meaning the Gate Key will no longer be functional, and the Zodiac Spirit will forever remain in the Celestial realm. The last condition is that the Zodiac spirit whose key is being sacrificed must havea strong emotional bond with the mage.

The key that is sacrificed for the summoning process then crumbles to dust, becoming completely unusable. This also means that the Zodiac spirit will not be able toleave the celestial spirit realm. However, the series later reveals that the sacrificed key reforges itself after a year, appearing at a random location in Earthland. Considering the consequences of this process, summoning the Celestial Spirit King is considered as a last resort when all hope is lost.

The Celestial Spirit King in Battle

Throughout the series’ runtime of almost a decade, the Celestial Spirit King is only shown in battle once – and that too as a last resort. During the Tartaros arc, Lucy finds herself fighting the dark guild’s strongest mage, Mard Geer. Clearly unable to match his power, Lucy is forced to sacrifice Aquarius’s celestial key, in-turn summoning the Celestial Spirit King. Upon being summoned, theCelestial King hurls from the skyand descends upon the Cube, destroying the floating island with one strike.

The fight reveals a few of the Spirit King’s potent spells, boasting immense power that is capable of destroying complete nations. First, he uses ‘Meteor Blade’, a frontal-assault in which he hurls his blade forward, slicing through terrain hundreds of miles away. As Mard Geer dodges all of his attacks with ease, the Spirit King is forced to use ‘Galaxia Blade’,a spell that dispels dark enchantmentin a large area. Another one of the Spirit King’s hidden powers is the ability to grant a person magical prowess, which is seen when he grants Aquarius’ power to Lucy, allowing her to rise up and fight the dark wizard.

Once he frees the Fairy Tail wizards from the shackles of Alegria, the Spirit King returns to the celestial realm, leaving the guild members to defeat Tartaros themselves.Fairy Tailflawlessly uses the god-like being’s power to move the plot forward, yet putting limitations and restrictions on his unfettered power, therefore ensuring the Celestial Spirit King does not become an overbearing plot armor in the series.
