Sebas Tian

Sebas Tian is the head butler of the Great Tomb of Nazarick in the anime Overlord. Created by the Supreme Being Touch Me, he oversees the male servants and leads the Pleiades combat squad (though the group is mostly maids).

He appears as an elegant elderly man in a traditional black butler uniform, with white hair, a white beard, and sharp eyes that belie his gentle demeanor. In reality, he's a powerful dragonoid (a dragon-like heteromorphic race) and one of Nazarick's strongest warriors, specializing in unarmed martial arts combat.

Unlike many Nazarick inhabitants, Sebas has a strong sense of justice and morality, influenced by his creator. He believes in protecting the weak and despises wickedness, though he remains fiercely loyal to Ainz Ooal Gown and will eliminate any threats to Nazarick without hesitation. He often serves as a scout or infiltrator in the human world due to his human-like appearance.
