Gerico, like many characters that Guts fights, is a rather large man clad in plated armor that covers his entire body. His helmet is designed to obscure everything except for his eyes, which is probably to mask the fact that his face is actually quite wrinkled. He has a rather large nose proportioned above thick lips while he lacks any facial hair whatsoever, which may suggest that he's bald.
Because he never officially speaks, there is no clear way to determine his personality. He may be as brutish as most enemies and desire only to win, shown in his fighting style against Guts however he almost appears to display somewhat of a dimwitted persona, suggesting he may be of a lower IQ level and only good for raw power. He does, however, show exceeded mastery of his weapon (the flail, or as it is otherwise known The Ball-And-Chain) which probably comes from extended training.
Black Swordsman Arc
- Gerico is one of many larger characters that Guts faces in his lifetime. This is a typical trend that occurs, making the already masculine Guts seem inferior in size to titan-sized characters however, with like almost all larger human characters, Guts is able to handle him without any problems.
- In the tradition of intimidating characters, another character (named or nameless) refers to testaments of their fighting ability or power. In Gerico's case, it was Minister Dahl who proclaimed his power to only be second to that of Captain Zondark.
