That part is what piss me off the most. Like it's just happening because the author decided it would, not because there's any logic to it in the story itself.
The MC suck so much, he just get fucked nonstop in all of his fights, he just get god mode in that last five panel with infinite healt and spam random generic punch until the other dude is KO. Not a single one of his fight is even slightly fun.
The problem with the MC's fighting style, it's that it isn't really suited for a manga since we don't get to hear the sound and rythme of his drum beating so it mostly look like generic spam.
It would be a banger if animated properly with a good sound direction tho.
Another lame fight with weird pacing and frankly Appolo was guaranteed to win to make the Greek Gods into not complet jokes.
The characters went from testing the waters to using their ultimate techniques super fast and Leonidas really did nothing all fight.
The whole twist with the fat rando is so shit, why undermine the greed that have been built up this whole time just to randomly insert some fat irrelevant rando with a dumb power that make no sense and essentially say 'I do whatever I want no matter what even if I'm literally dead'?
