This is factually untrue. Orochi is still alive and kicking after two punches from Saitama currently.
Haven't caught up to the manga yet. The last chapter I read was Tatsu flipping the base, so I'll withhold judgment on the merged Orochi. But it still doesn't change the fact that he was below Boros by feats and portrayal. And will more likely than not be below him even in the merged version.
Great post. Didnโt expect you to go all out on opm
