Who are the four emperors ?
during reading the latest chapter , law asks luffy to make an alliance with him to beat one of the four emperors.
so who are them ?
I think they are the yonko because the yonko are the most dangerous pirates in the world including the new world so Law wanted to make an alliance weith luffy (or the SH) because he couldn't beat a yonko without helping from a strong enough friend like luffy.
now what is your expectation about the four emperors ?
