his flames dropped king's durability even with King's flames on for long enough for Marco to land an affective blow?
not only that's a REACH but an unfounded phenomenon where marco's flames aren't seen on king yet they somehow have an affect over him by dropping his durability.
Marco's flames work like that too I HAD'NT A CLUE
you're choosing the least patent and a flagrantly unlikely possibility than the likely.. which i believe its much more reasonable and doesn't need much mental gymnastics
idk about how durable he is without the flames but he was down for a decent amount time after Marco kneed him..
he didn't recover immediately after that kick even perespero had his monologue reacting to Marco who's down chilling.. yet king is no where to be seen.. matter the fact the next chapter Marco and Chopper are bullying Queen and King still isn't shown to distract marco when King himself said his hands are full with marco.
