I suggest cu chulainn and emiya Archer or the great kid Gilgamesh or his caster version but I also think that Heracles would be perfect for the battle of the century against the hulk
The story will mostly follow the event in MCU but with a mix of xmen and comic element in it, so the difficulty level will be much higher. Anyway, thanks for the comment, I appreciate it.
IsekaiFan:This is in my opinion but author, you're making a good novel, so just make whatever you like and don't need to follow everything others say, is just a servant recomendation make everything just as you like to be
