Fudo della Montagna (フドウ, Fudō) serves as one of the five Nanto Goshasei (Nanto Five-Star Generals) under the Last Nanto General, Yuria. He embodies the Star of Benevolence (仁星 Jinsei) and wields the Nanto Hōō Ken (南斗鳳凰拳, "South Star Phoenix Fist"). His imposing presence features a massive, muscular build, bald head, and distinctive facial scars.

Originally a ruthless warlord who terrorized villages, Fudo's path transformed upon encountering Yuria. Her profound compassion and kindness moved him, leading him to renounce violence and pledge lifelong loyalty to her. He became her steadfast protector, driven by a desire to atone for his past.

As a Nanto Goshasei, Fudo fights critical battles for Yuria's cause. He confronts Raoh, the eldest Hokuto brother, but suffers defeat. Despite this loss, his fierce devotion to Yuria remains unshaken. His combat style merges brute strength with precise technique, using his immense physique for powerful strikes aimed at pressure points.

Fudo's character arc traces his evolution from merciless conqueror to a symbol of unwavering loyalty. His interactions consistently reflect his commitment to Yuria's safety and ideals. He appears in the *Shin Kyūseishu Densetsu* film series, including *Legend of Yuria*, where his role as her guardian is explored.
