Gray Fullbuster

Gray Fullbuster (グレイ・フルバスター, Gurei Furubasutā) is an ice wizard who is fierce rivals with Natsu because of their opposing personalities and magical elements.[ch. 10] Orphaned by the Etherious Deliora (デリオラ, Deriora) at age eight, Gray is tutored by Ur to use Ice Make (氷の造形魔法, アイスメイク, Aisu Meiku), which instantly produces ice in the form of any weapon or object he imagines;[ch. 21] during his training to withstand cold temperatures, he also gains the habit of subconsciously stripping his clothes, something that Mashima based on a personal habit of his own.[8] He joins Fairy Tail after Ur sacrifices herself to save his life when he recklessly attempts to kill Deliora. Later in the series, Gray inherits Ice Demon Slayer Magic (氷の滅悪魔法, Kōri no Metsuaku Mahō) from his reanimated father, Silver, becoming a Demon Slayer (滅悪魔導士, デビルスレイヤー, Debiru Sureiyā, lit. "Devil Slayer") to carry out Silver's will to destroy E.N.D. The corruptive influence of his demonic powers compels Gray to irrationally fight Natsu upon discovering his identity as E.N.D.,[ch. 449, 450] but he ultimately uses his powers to help strip Natsu of his identity as an Etherious so he may live normally as a human.[ch. 538]
