Gray Fullbuster

Gray Fullbuster (グレイ・フルバスター Gurei Furubasutā) is a member of the Fairy Tail guild. He is an 18 year-old ice mage, practicing ice alchemy, the art of molding ice. Due to his training history, he is most comfortable in little clothing and often forgets to wear clothes or quickly takes it off, thus often being accused as an exhibitionist. He and Natsu have a friendly rivalry, and can often be seen fighting one another. Lucy believes the nature of his magic is the reason that he and Natsu constantly bicker. His member stamp is below his collarbone.

History
Much of Gray's history is revealed during the Garuna Island arc. Gray teams with Happy, Lucy and Natsu on an S-Class Mission after being sent to retrieve the trio by the Master. Despite finding the trio and engaging Natsu in a fight to bring them back to the guild house, he quickly succumbs to his curiosity and pursues the mission. The primary antagonist during this arc is Reitei Leon, who is revealed to be Gray's former peer and a student of Gray's teacher, Ur, a powerful ice mage and one who Sieglein claims would be a Ten Great Holy Mage if she were still alive. Ur took in Gray as her student and child after finding him in a destroyed town. Gray's parents and entire town was leveled by the demon Deliora. As result, Gray accepts the training in order to eventually avenge his parents. During this training, Gray picks up his unusual habit of undressing in public.

However, due to Gray's obstinacy, he chooses to prematurely challenge Deliora, leading to Ur's self-sacrifice in order to encase Deliora and protect Gray and Leon. Gray seems to have inherited this similar selfless personality, shown during his two attempts to use Iced Shell (a move which turns the caster into ice) on Leon and Deliora to protect his team.

Abilities
Gray's adeptness and strength as an ice mage is quickly shown in the story. During the Lullaby of Death arc, he teams with Natsu and Erza to defeat the demon awakened from the evil spirit from the Lullaby of Death. Members of the League praise his quickness at molding ice. Later in the story, he defeats Jubia, one of the Elemental Four of Phantom Lord. This victory may have been partly influenced by Jubia's liking to Gray. Jubia comments on Gray's skill, shocked that he was able to freeze both her boiling water and the rain. After Phantom Lord's defeat, Jubia secretly spies on Gray, bringing a packed lunch for Gray while he and the guild are rebuilding the headquarters.

When Loki's identity had been revealed, Gray and his friends went to a holiday trip, shockingly, Jubia secretly spied on him. She even admire Gray's courage to take off his pants and underwear in the sea. She then took her approach to Gray, while chatting, she was attacked by a unknown person who is tall and huge. Gray was angry that the person attack Jubia without any known reason, it seems that they are looking for Erza.
