Oden
The Scabbards
Hyogoro, the dude in this very chapter wiping the floor with everyone.
Yeah, Orochi’s goons are just average fodder, but they’re meant to be traitorous disgraces of samurai. The ones who are considered real samurai have more than lived up to the hype. Imagine a pirate crew with Oden as Captain, the Red Scabbards and Hyo as his main crewmates and then the three thousand samurai on Luffy’s side as his fodder. Would be pretty beastly.
