King Moai

King Moai is the king of Arlia after he won the war against the Kingdom of Arlia. He is a cruel and ruthless dictator who imprisoned Atla and all the good Arlians, and held battles between his guards for entertainment, in which the loser would be fed to the giant Arlian Yetti who resided in his palace's pit. Once his guards were killed by the Saiyans' overwhelming power, Moai panicked and upon Yetti's demise, his cowardice came out in full as he desperately hid behind his own throne and begged for mercy.
