Corkus (コルカス Korukasu) was a member of the original Band of the Hawk who was killed during the Eclipse as a sacrifice.
Corkus is depicted as a brown eyed man in his thirties, quite tall and thin. He has smooth black hair that comes down to the base of his neck. Corkus wears a plain purple short under his grey armor along with a pair of brown trousers. He often fought with a short sword but was also seen with a crossbow.
Corkus was depicted as antagonistic towards Guts (oftentimes without provocation) and fiercely loyal to Griffith, though even he admits that Guts is very valuable to the Hawks, as even he started to fear when Guts broke his sword in the battle with Boscogn. His hatred towards Guts is largely one-sided, as Guts doesn't have a major problem with any insults or attempts at assault that may come from Corkus and even seems to value Corkus as a member of the Hawks. Corkus has expressed his hatred of Guts at its fullest when the latter decided to leave the Hawks, stating that he hated the swordsman's face as something that appeared to bear all the burdens of the world.
Corkus usually appeared very cynical and world-weary, but was hinted at being a very idealistic man underneath. Judeau has stated that Corkus once tried to win something for himself, but failed and since then has been reveling in and arguing in favor of any new found glory and privileges that he obtained under Griffith in order to stave off those feelings of loss. Confronted with Guts' decision to leave the Hawks, Corkus does not hesitate to reveal that he aimed and shot his arrows at Guts' back in several battles. Whether this was true or simply Corkus' way of dealing with Guts' departure and pushing him forward is unknown.
- The Apostle that kills Corkus is the same one Guts killed in the very first chapter, Guts probably wanted to take his revenge on her for that specific reason.
- In the anime series he was voiced by Tomohiro Nishimura in Japanese, and by Mark Sebastian in English.
- In the Berserk Film Trilogy, he was voiced by Yoshiro Matsumoto in Japanese, and by Doug Erholtz in English.
