Overlord Zenon. Known as the God of all Overlords in the multi-verse. His power is feared and envied far and wide. Known to have beaten over a thousand Overlords in the past before retreating into seclusion, he suddenly reappears on the world of Veldime - cursing its inhabitants into demonic forms.
He is, in fact, feeding on their very humanity, allowing him to seal the immense power sleeping within his sheltered daughter's, Rozalin's, form.
The more power he needs to fend off the attacks of ambitious Overlords (like Etna and Laharl!), the faster the humanity of Veldime's people is drained, turning them into vile, selfish creatures in more than just form. All eyes are on Zenon as this powerhouse blazes a new path of destruction through Godlike and Veldime alike.
