Either Sommers or Kilingham is meant to be Shamrock’s replacement, indicating that one of them is at least relative to his strength. Probably Sommers since Kilingham was the one needed to kidnap the children
If Shamrock is a high top tier then Sommers might be mid top tier ngl. And I doubt Kilingham who is a mythical zoan HK is a scrub either
I’m sure Oda can make them top tiers since we haven’t seen their abilities in action yet, but from a stakes or characterization standpoint, I’m still not convinced they’re fit to be main arc villains. Compare them to the Gorosei, Doffy, Kaido, etc.. there’s just not enough buildup.
I’m hoping they get taken down, and Shamrock teleports in to save them. I want Luffy to meet him so bad.
