August is a major antagonist in the manga/anime series Fairy Tail. He is the General of the Spriggan 12 and is said to be the strongest male Spriggan 12 member (with Irene Belserion being the strongest female).
He is also the son of Zeref Dragneel and Mavis Vermilion and the nephew of Natsu Dragneel but his relationship with his family is kept hidden and is never revealed outside to anyone. He appears in the Alvarez Empire arc as a supporting antagonist.
He is voiced by Yoshito Yasuhara as an adult and Natsumi Fujiwara as a child in the Japanese version of the anime, and Bruce DuBose as an adult and Brittany Lauda as a child in the English version of the anime.
August is a white-haired elderly man with a long beard who wears a torn robe with a large collar piece behind his head. He carries around a staff with a purple gem on top of it.
In his battle form, his appearance changes quite drastically with his hair appearing to be more grown out and his robe being removed from his top, revealing his muscular physique and symbols around his torso area.
August is loyal to his master and a good leader to his other 11 partners, even at times willing to talk with others. Although he’s also willing to sacrifice them when they are defeated and has displayed evil tendencies such as wanting to kill Cana in front of her father Gildarts.
August often comes off being strict and stern, rarely showing any sign of emotions. Despite this, Brandish states that August is the one that is the easiest to talk to and is willing to at least negotiate with his enemies, despite his loyalty to Zeref. However, he is shown to have a quick temper as when Mest attempted to kill him by manipulating Brandish, he immediately lashed out into his battle form and began to attack his opponents.
