Locus is a key character from Berserk, known as the Moonlight Knight. He is an apostle who serves under Griffith, one of the most prominent figures in the series. Locus is a knight of legendary status, famed for his undefeated record in jousting and battle, and he initially resisted swearing allegiance to any leader. However, after a vision, he pledges his loyalty to Griffith and becomes one of the generals of the reformed Band of the Hawk.

In his apostle form, Locus undergoes a dramatic transformation, merging with his horse to take on a centaur-like appearance. This new form features a silvery metallic sheen with numerous hooked protrusions. His shield is integrated into his left arm, and his lance is transformed into a long, sharp double-ended spear, enhancing his combat abilities. His skill with a lance is unparalleled, and he can strike down multiple enemies in one blow. In battle, Locus is both fast and agile, using the combined speed of his horse and his own strength to devastating effect.

Locus is known for his stoic, honorable nature and strategic mind. He is a highly respected leader among Griffith’s forces, balancing his monstrous apostle abilities with a sense of duty and integrity. Despite his apostolic nature, Locus retains a considerable amount of humanity and is often seen alongside Griffith during formal events or important discussions​
