User blog comment:Emptylord/Custom Champion - Muzen'Khan the Wings of the Abyss/@comment-3974211-20140917161934

All void champions, to date, are driven by a hunger (of sorts). Or, they can be seen to devour at any rate - Cho'Gath, Kog'Maw (at least in lore), Kha'Zix (striving to be the best) and Vel'Koz (devouring information with his eyes - nothing survives being studied by Vel'Koz!). Muzen'Khan currently lacks that element. Technically he can hold an enemy in his mouth, but I'm not sure that's sufficient. During development, Willbachbakal proposed that Muzen could hunger for magic - and he was given the passive to see nearby spellcasters. I'm interested in pursuing this more.
