rather than giving king some power it would be better if he only got conqueror haki but nothing else.
It would intimidate all his enemy to be scared but he can't do anything to to them kind of like in OPM
Thanks for the suggestion, but I already have a plan on how to make the MC OP. However, I want to mention that he can't always scare people with his face and aura alone. There are many pirates who don't fear death.
Thanks for the chapter and it would be nice if King soon got something from the system that increases his physical strength permanently and maybe some fighting style that takes advantage of his extreme luck, overwhelming aura and system enhanced physical strength.
It would also be interesting to see what would happen if you give King the "Raki Raki no mi", since in case his extreme luck works like that fruit, if the power of the fruit adds to the King luck then his luck would be of more than 8000 xD.
