Virion

Virion is an S-Class Mage of the Fairy Tail Guild, wherein he eventually becomes a member of Team Natsu.

Personality
In his first appearance, Virion is shown to be fun-loving and mischievous, with little regard for the law. He has a lot of self-confidence, referring to himself as a "great stowaway". He also has a strong crush on Elise.

In conversation, Virion is very laid-back and casual. He is also kind and patient. When first meeting Elise, he is willing to listen to her story and waiting for her to open up for nearly two days, bearing with her "small talk and weird looks". He is not afraid to give his opinion and has a dislike for those who regard themselves as "holier than thou" or "use force to get whatever they want".

Virion also seems to be willing to help others, regardless of whether he is asked or not, even if he barely knows them. When first joining Fairy Tail, he goes out of his way to help Elise, whom he had just met and barely knew. This quality is further demonstrated when he readily volunteers to help Team Natsu with their investigation.

He also does not like it when people dear to him have to risk their lives. However, Virion is willing to put himself in harm's way for those he cares for.

Virion persistently remains at Elise's side and continues to try to help her in any way he can. He expresses wisdom in pointing out that Elise's friends want to fight for her, and that she should not try to distance herself from her friends because she feels responsible for bringing harm to them. In that respect, Elise believes Virion to be the embodiment of the word "earnest".

Magic and Abilities
White Dragon Slayer Magic (白の滅竜魔法 Haku no Metsuryū Mahō): A form of Dragon Slayer Magic which allows Virion to transform the physiology of his body into that of the White Dragon, allowing him to generate and manipulate light to his every whim. The White Dragon Slayer's element has been described as being holy, with Virion remarking that his opponents suffer the "judgement of the holy white". Virion as a White Dragon Slayer has the ability to consume anything White as stated by Virion himself.
 * White Dragon's Roar (白竜の咆哮 Hakuryū no Hōkō): Virion's signature Dragon's Roar takes the form of a, comparatively, small laser with effects not unlike it; it slices the ground it strikes, creating a linear explosion in its wake. After, through unknown means, devouring a metal arrow that was fired at him, Virion was shown using a different Dragon's Roar, this one consisting of a powerful, larger whirlwind which pierced through several buildings with ease, leaving a clean, round hole in each of them.
 * White Dragon's Holy Breath (白竜のホーリーブレス Hakuryū no Hōrī Buresu): A seemingly stronger, more potent version of his White Dragon's Roar, Virion jumps over his target and releases a large, extremely powerful burst of light from his mouth; such a spell was shown capable of easily reducing the Domus Flau's arena to rubble, creating a large, almost cavernous hole in the ground in the process.
 * White Drive (ホワイト・ドライブ Howaito Doraibu): A technique which, according to Mavis Vermillion, amplifies Virion's Magic abilities, completely cloaking his body with an aura of bright light, allowing him to better employ his Dragon Slayer Magic whilst at the same time seemingly enhancing his physical prowess to a degree, particularly his speed. According to Virion himself, White Drive harnesses "the power that kills Dragons", and it indeed allowed the White Dragon Slayer to momentarily overwhelm Basilio, who had him almost outmatched beforehand. This state either grants Virion the ability to perform new spells or makes them stronger, as the Fairy Tail Mage has been shown employing several skills only while in said Drive.
 * White Dragon's Claw (白竜の爪 Hakuryū no Tsume): A close range spell which is described as being a "holy attack", Virion performs White Dragon's Claw by generating a sphere of light around one of his hands and then firing it at the target. If said blast connects with the body of the target, it tears through clothing and blackens the struck area, leaving a light, complex marking on it (a so-called "Stigma") which, according to Virion, takes away the body's movement, thereby leaving the foe open to the White Dragon Slayer's subsequent attack. It is currently unknown how much said spell limits the target's freedom.
