Ok, so basically if Ban and King get possibly
higher due to surviving DK Zeldris' attack, the rating would be like this:
Demon King possessing Meliodas:
Attack Potency: At least
Island level (Easily overpowered
Afternoon Mael), possibly
higher (Overpowered
Full Wings King and damaged
Ban, both of whom were able to withstand a
magic attack from the Demon King who was possessing Zeldris)
Durability: At least
Island level, possibly
higher (Took blows from Post-Purgatory Ban)
Ban:
Attack Potency: At least
Island level (Comparable to Post-Purgatory Base Meliodas. Traded blows with the Demon King who was possessing Meliodas), possibly
higher (Was able to
just barely damage the
Demon King who was possessing Zeldris albeit Merlin stated that he was practically unscathed. Was capable of trading blows with the Demon King possessing Meliodas who was able to damage him),
Varies with Snatch (Snatch is capable of stealing the opponent's speed and adding it to Ban's own)
Durability: At least
Island level, possibly
higher (Took hits from a Demon King who was possessing Meliodas. Withstood a
magic attack from the Demon King who was possessing Zeldris),
Varies with Snatch (Snatch is capable of stealing the opponent's physical power and adding it to Ban's own)
King:
Attack Potency: At least
Island level (Effortlessly overpowered and stomped
Four Commandments Absorbed Mael. Damaged the
Original Demon while remote controlling Chastiefol from far away), possibly
higher (Was able to
just barely damage the
Demon King who was possessing Zeldris albeit Merlin stated that he was practically unscathed)
Durability: At least
Island level, possibly
higher (Withstood a magic attack from the Demon King who was possessing Zeldris)
And Merlin damaged the DK so she could get a possibly higher.
Merlin
Attack Potency: Island level (Knocked out Unsealed Demon Mark
Meliodas and extracted his power in the past. The mere mention of her true identity caused
Fraudrin and
Grayroad to completely lose their composure. Blasted a hole through Grayroad with Exterminate Ray and forcefully prevented her escape with a casual Endless Whirl spell), possibly
higher with Infinity (Can enchant her magic and make it overpower True Form
Chandler’s Exterminate Ray at night. Was able to
barely damage the
Demon King who was possessing Zeldris)
