I wonder how the Lunarians would compare to Sulong Minks.King is not the average Lunarian,he is a YC1.
I think that they on average are much stronger.
Their physical make up (dura/strength) seems to be incredible, greater than the minks and fishmen overall. Can't forget that the dukes or Jimbei are prime examples of their own race aswell, but they seemingly got nothing on King's dura and strength as it seems, indicating higher natural potential to me.
But the deciding factor would imo be their abilitiy to fly and their control over fire.
Even if weaker lunarians get outmuscled by some Sulong minks for example, they could still stick to flight+long range fire nuke. Afterall that's their natural ability, independent of King's individual status and its a decent and effective strategy.
I for example cannot imagjne a guy like Jack successfuly raiding them, even if most of them might not even be high or stronger mid tiers overall.
As a collective they must have been an incredible fighting force.
One S-class DF power spam and they still are dying like flies tho lol
