Guts is on his own level lmao.
I have only seen Berserk movies but his character archetype is much more complex then Zoro's. He lost something, and his failure follows him everywhere in the form of that scar on his neck and his goal is life is to get over that. While Zoro is a great written character, his archetype is very simple, he is simply the guy with ambition to get stronger strengthened by his child hood and great moral compass,
Oda simply isn't capable of writing a character as complex as guts but Pre TS Zoro is the best work Oda has done. Zoro is on the very top by One Piece standards but Guts' standard is much higher than what One Piece can offer.
@Admiral Lee Hung those movies are really making me wanna start reading Berserk.
