Yeah I wish they didn't call him "The King of Hades" since I feel that a title like that would be fitting for Master E.N.D. Maybe Prince of Hades....or Prince of Darkness, since it would indicate that there is an individual higher than him. Marde Guille seems like he will be tough so I have high hopes for him. Don't disappoint like Kyouka. Also I agree, he does look like Zeref and Cobra.
