Yup... that was definitely an Ace punch. There was a reason he earned the nickname fire fist. Thankfully Marco was prepared for it after the pole punching incident, and his punch meets fiery phoenix flames that absorb most of the damage for him.

Dammit Ace... Marco's trying to mope here. First Thatch, then everybody else... does this mean Whitebeard and Thatch are going to wind up punching him in the face soon? God he really hopes so... and what kind of a sorry state of the world it is when he's hoping that?

"Calm yourself oh fiery one." Because trolling was Marco's default, and when his brain was too fucked up to even comprehend what was even going on anymore, that's what he did.
