Torin Baelfyre

Torin Baelfyre (トゥリン・バエルファイア, Tourin Baerufaia) is the name of an extraordinarily powerful user of Dragon Slayer Magic who is now one of the only remaining living relics of the historical who sided with the humans during the war, as well as the younger brother of Torik Baelfyre who is imprisoned as he is classified as being too dangerous to be let loose. As a Dragon Slayer that fought against the dragons during the war, Torin is known for having slayed countless dragons, and as a result of his countless battles was eventually transformed into a dragon in human form from bathing in blood of all of his slain enemies, and causing him to potentially gain immortality, or at least a lifespan that superseded humans by centuries. During his time fighting against the dragons in the war Torin gained the title of Torin of the Absolute End (絶対終了のトゥリン, Zettai Shūryō no Tourin) for his ruthlessness in slaying the winged creatures and for his signature dragon slaying element.

After the war had reached its conclusion and the need for Dragon Slayers diminished Torin set out to parts unknown, but wanting to stay connected to the modern societies is known to have changed his physical appearance every few decades so as to remain hidden in plain sight. As of now his current whereabouts are currently unknown.

Trivia

 * Torin's appearance is based off of several different characters; first is Haku from the Naruto series by  Masashi Kishimoto for his masked appearance, second is Judar from the series Magi: The Labyrinth of Magic by Shinobu Ohtaka for is actual appearance; and lastly (for the moment) his appearance from 400+ years ago is of the manifested form of Tōshirō Hitsugaya's zanpakutō Hyōrinmaru from the series Bleach by Tite Kubo.
