Most likely yes, I agree.
They would have those base abilities that every Lunarian inherit but they would surely not be as powerful as King imo. Especially since Haki also plays a role.
An army of giant-lunarian hybrid soldiers who are obedient to the WG does sound menacing, easily the strongest out of the numerous "armies" we've seen so far (SMILES, homies, Giants etc,.).
I doubt they are individually high tiers, atleast I can't imagine how an army of obedient high tiers would look like... especially considering that the Shichibukai themselves were a mix of strong high tiers & stronger characters, so an army of even weak high tiers would probably blow them out of the park.
Like the quantity & quality of them should compensate most likely; as in the lesser the number of Seraphims, the stronger they are individually. If they are made in large numbers, then I doubt they are that strong individually.
Yeah I know what you mean, but imo those base lunarian traits are already very powerful and by default pretty much make you a high tier, even if they are mass produced.
The Pacifistas were already in a sense that, what you are arguing for and with the lunarian lineage factor mixed in, they should be noticeably stronger. I mean just imagine lunarian Pacifistas: Doubtful that even P1 can scrap with one of those tbh.
Obviously a big IF, cause I don't know their exact abilities, but if they are gigantic, super strong dudes with fire spam moves and especially that lunarian super durability, that also can fly.. Very big oof.
And they somehow should be strong enough - if not for fake hype - to really replace the shichibukai.
Alone for Mihawk you honestly would already need a batallion of high tiers, if they are really meant to match up to him.
Probably the same with Weevil and here we got Boa going apeshit aswell. Then you got post ts Law, awakened Doffy, brain Kuma with Ursus shock and teleportation.
A guy like Primebeard or as seen at hand of BB in this chap, would probably not even be replaceable at all, as they can nuke anything below top tier at rofldiff anyway.
I hope you get where I'm coming from. Imo you can hardly blow those guys out of the park, even tho I obv. know what you mean.
