Also, note: Surpeme King (Haou) more specifically in its meaning, could mean "
Tyrant".
As in one who rules by force rather than elected or divine right. A
good example of this would be the Tokugawa shogunite. Basically, its a
ruler who forces squabbling tribes to unite under him, and if you won't
bow down, you get the axe. Or in Juudai's case, Inferno Wing's claws at
your throat.
And in the World of Monsters, especially Dark World, which is ruled by
authority of level and strength, a Tyrant would be a perfect example, as
Juudai himself (Haou), that Dark World was a world ruled not by the law
of man, but rather by the law of the jungle, kill or be killed.
