The Overlord anime is filled with exciting characters, from valiant knights to dastardly evil schemers. As Ainz puts his plans into motion, he becomes the target of some of the most evil characters who seek his demise for threatening their control. Assassins, secret syndicates, and even royal blood fill the ranks of evil-doers, though the most evil Overlord characters really are in a league of their own.

Zanac Vaiself is the second-born heir to the throne of Re-Estize. While he thinks himself a noble and adequate successor to the throne over his older brother, he resorts to all sorts of underhanded tactics that he deems as being “best for the kingdom.”

Zanac uses all advantages and tools at his disposal to ensure things fall in his favor, including murder, espionage, and betrayal. While his outward appearance is off-putting and disheveled, Zanac is not a cruel individual and does not wish evil on innocent citizens even if evil must be done. However, there is no line Zanac won't cross to empower his kingdom and his own political position.
