The Godfist of Remnant

Jaune Arc was never seen as a fighter by his family. And so, they never instructed him. However, his life changes when he meets a mysterious man with seven bullet-shaped scars on his chest, who trains him in the ways of the martial arts. After four years of his tutelage, Jaune comes to Beacon, wielding powers and techniques unlike any Huntsman. (Major canon divergence, OP Jaune)
