I’ve got many thoughts related to the Seraphim but I’m not gonna push those yet without a bit more info. IMO it proves Lunarians are stamina beasts but I need a bit more from Oda
The way those powers are laid out simply don't work, it's stupid why would they ever turn the flame off? Have King tank thunder baguas all day long because flame off.
Oda didn't explain well or didn't thought fully his powers. Should have just made King awakened ancient zoan with his race having powers opposite to fishmen, fire conjuring/bursting fists and flame resistance, some shit like that
No weakness to his on off switch and any matchup vs him becomes just him draining his opponents because he has the tools to do so. King vs Kaido? King tanks his attacks all day long until Kaido's haki weakens.
Maybe have lunarian flames be extinguishable like real fire and they need to re-ignite them which drains their stamina over time? Could have worked too as a weakness.
