Beldia

Beldia is one of the Demon King's Eight Generals in KonoSuba: God's Blessing on This Wonderful World!.

He is an undead Dullahan (a headless knight) who carries his own severed head. Beldia is arrogant, prideful, and looks down on humans, frequently boasting about his status and power. He wields a powerful sword and possesses abilities typical of high-ranking undead, including a Death Curse that can instantly kill those who look directly at his face (though Aqua is completely immune to it due to her goddess status).

He serves as the main antagonist of the early story arc where Kazuma's party first properly takes on a general of the Demon King. Beldia is ultimately defeated by the combined (and very chaotic) efforts of Kazuma, Aqua, Megumin, and Darkness.
