Mercuphobia (メルクフォビア Merukufobia), also known as The Water God Dragon (水神竜 Suijinryū), is one of the Five God Dragons that inhabit the continent of Giltena. After being defeated by Natsu empowered by the flames of Ignia, his Magic Power became obsolete insisting he'll remain in his human form as a regular human.
Mercuphobia’s appearance is similar to that of a sea serpent, with a scaly underside, large wings, and a long, pointed nose. He bears a tribal-like design on his face while maintaining his two horns. Mercuphobia is enormous even for a dragon; being stated to be larger in size than the fire dragon, Igneel and being shown to dwarf the aforementioned dragon's son Ignia.
In his human form, Mercuphobia appears as a young man with shoulder-length hair, two long horns, and a facial tattoo over his right eye. He dons a dark coat over a long shirt, accompanied by loose pants tucked into pirate boots. His accessories include a necklace with three circular ornaments and black gloves that only partially cover his palm.
Mercuphobia is a calm dragon worshipped as a god by the people of Elmina, although he can easily become hostile towards those he views as enemies. Conversely, he is quite welcoming towards the town’s visitors or those who have earned his trust, visible by his hospitality towards Team Natsu upon their arrival. Mercuphobia takes responsibility for the care and well-being of the citizens of Elmina, presiding over them as a benevolent ruler while also driving away any threats to himself or the town. He is particularly dedicated to his assistant, Caramille, who he states is his “reason for living.” Despite his kind-hearted nature, Mercuphobia acknowledges his cruelty and violence as the Water Dragon, admitting that he previously thought of humans as comparable to ants. Because of this, he regards himself himself neither good or evil, although he openly supports coexistence with humanity.
Due to his growing frustrations about his powers’ threat to Elmina, Mercuphobia constantly worries for the citizens’ safety and considers himself a danger to them. As such, he has become unafraid of death, even resorting to have Elefseria’s assassins to kill him in an attempt to sacrifice himself for their sake.
Mercuphobia existed as far back as the Dragon King Festival, having killed numerous humans, some of which included Elefseria’s family. He along with the other Five God Dragons fled to Giltena in order to escape Acnologia and became known later became known among that moniker of "gods". After some time, he rescued Caramille, a human who had been shipwrecked in his sea. From there, Mercuphobia became a peaceful dragon who supported coexistence with humanity, ultimately coming to lead the people of Elmina Town, who worshipped him as a god. He later requested Carmille to locate the White Wizard to remove his powers before they end up out of control, but the White Wizard only removed the control of them, allowing the White Wizard to manipulate his power at their behest.
100 Years Quest arc
Mercuphobia witnesses Team Natsu entering Elmina as Caramille informs him that they are residents of the southern continent. Hearing the confrontation between Diabolos and Team Natsu, Mercuphobia descends into the ocean, parting the seas and demanding that the two parties leave Elmina. However, the dragon eaters are suddenly teleported away by Black Ash, much to the Water Dragon’s surprise. He then inquires of the Fairy Tail mages’ objective, to which he learns that they have been sent by Elefseria, although with no intention of unnecessary violence. Mercuphobia acknowledges their peaceful approach and invites the group to his palace, instructing Kashima to treat them as his guests.
At his palace, Mercuphobia undoes Lucy’s transformation magic on Wendy, who had been turned to a jellyfish, and briefly introduces the group to Caramille. Amused by her ill-mannered response, Mercuphobia requests that she leave before explaining his history with her to the mages. He also describes his past as the Water Dragon, admitting to having killed Elefseria’s family, although he assures the group that he now supports coexistence with humanity. Mercuphobia then proceeds to showcase his numerous underwater facilities, managing to convince Team Natsu of his good will and merit through his dedication to the people of Elmina. However, he also confides in them his uncontrollable level of magic power, which he explains are the reason for town’s unnatural submersion at high tide. Believing that he poses a threat to the citizens’ safety, Mercuphobia requests that the mages kill him to prevent a potential calamity, although not before he is able to correct a critical error.
Revealing that his powers have been stolen away by a person called the White Wizard, Mercuphobia admits his fears of his magic being misused and firmly resolves to reclaim his powers. However, they are interrupted by the arrival of the Diabolos mages, who overhear Mercuphobia’s confession and decide to steal his powers from the White Wizard themselves. Angered, the Water Dragon sends a wave towards the trio, but is quickly defeated by Skullion. Unable to fight, Mercuphobia watches the Fairy Tail mages fend off the dragon eaters. However, he later shields Caramille from Kyria’s attack, and is heavily wounded as a result. After Team Natsu leaves to pursue the Diabolos mages, Mercuphobia is tended to by Caramille in his palace. He later awakens, but suddenly grabs his assistant’s neck forcefully, yelling for her to flee.
As a result of the White Wizard maximizing his magic power, Mercuphobia reverts to his dragon form and proceeds to rampage through Elmina. In an attempt to stop him from harming the citizens, Mercuphobia is attacked by Team Natsu with a barrage of dragon slayer magic, but he remains unscathed and lifts the sea above Elmina. Mercuphobia sends a destructive water-based attack down on the harbor, and counters the Mages by neutralizing Natsu’s magic and dispelling Gray’s ice. The former manages to jump onto the Water Dragon, although Mercuphobia continues to negate Natsu’s magic with ease. He creates a vortex from the sea overhead, which envelopes the dragon slayer; however, Ignia, the Fire God Dragon, lifts Natsu out of the vortex, refusing to hand him to Mercuphobia.
Still under the influence of the White Wizard, Mercuphobia is unable to comprehend Ignia’s inquiries about his state of mind. As the latter utilizes his power to burn the harbor, Mercuphobia brings rainfall down on Elmina in order to extinguish his fire. After Ignia departs from the battle, Mercuphobia is suddenly ambushed by Natsu, who has been strengthened from consuming the flames of the Fire God Dragon. Mercuphobia is thrown headfirst into the town structures by the dragon slayer, completely overwhelmed by his newfound power.
