That's why he's likeable lmao. it was funny asf. i'm really tired of seeing the big antagonist being untouchable or 24h looking good and lit like Kaido, Katakuri or Doflamingo, Blackbeard is the casual carefree pirate guy in the series. he gets curbstomped, then succeeds at a certain goal. pretty much like Luffy
remember not every antagonist can share each other's traits. Doflamingo was obviously better in terms of being that manipulative villain that tricked the three powers, but Blackbeard is
not meant to be the same. he represents a more casual antagonist, he has that mix between courage and cowardice. OP allows you to enjoy different types of antagonists, unlike other bland mangas.
