Beldia

Beldia (ベルディア) was a Dullahan, a former knight, and one of the Demon King's Generals.

Appearance
Beldia is a headless undead knight clad in dark grey armor who rides a black headless horse.

Personality
While his negative actions are predominently shown, it's later revealed that he is also hardworking and dedicated; after moving into his base of operations near Axel he would work alongside his grunts repairing the various damages to it caused by Megumin's explosions, showing a tolerance for it at first (dismissing it as nothing but a "test of courage"), but eventually reaching a breaking point and assaulting the town, something he had not planned originally.

Beldia claims himself to be a honorable knight but displays extreme pride of himself. Along with this, he displays a sinister side of evil of him and has no restraints on cursing those to their demise. One notable trait about him is that he can be easily provoked and lash out in rage as he assaulted Axel out of anger towards the person that was bombing his castle. Prior to this though, he has shown a bit of tolerance for those actions done to him before eventually being fed up with it.

Though he claims to be honorable and still retains some chivalrous and honorable aspects of his former life he is in fact a closet pervert, but he is too proud to admit it and refuses to reveal this side of himself to the public. Wiz described him as the "type of man who would look under a woman's skirt", as she recalled a time when Beldia would regularly throw his head to look under Wiz's skirt.

Despite his evil nature, Beldia does not seem to be completely heartless and has shown a more genuine, but insecure side of himself. He patiently waited for Megumin to come to his castle before battling her, but became greatly upset when neither she or anyone else arrived to his castle. He has also shown a warm and compassionate side towards animals.

History
Beldia was once an honorable knight that was unjustly executed. Afterward, his grudge over this matter transformed him into a Dullahan. Later on at some unknown point in time, he joined the Demon King’s army (and indirectly became the reason Wiz became a lich, due to him cursing the latter's companions). The Demon King later sent him to Axel to investigate a mysterious light that had suddenly appeared, which was likely caused by Aqua's appearance in their world.

Abilities
Being one of the Devil King's Generals, Beldia is naturally much stronger than most of the other creatures adventurers regularly face. His durability is such that he could survive both Aqua's Turn Undead and Sacred Turn Undead, spells highly effective against undead creatures, Megumin's Explosion and Aqua's Sacred Create Water, while still having enough energy to keep fighting. Additionally his swordsmanship and fighting skills allowed him to easily battle and even kill several adventurers without suffering a single blow. Beldia was also shown to be exceptionally strong physically, able to hold back Darkness, who own physical strength is exceptionally high.

Premonition of Death: A deadly curse that will kill its target within a week. It is extremely potent, seemingly only curable by those with divine powers.

Undead Knights: Beldia is capable of quickly summoning a group of undead knights; However, he does not have full control of their actions and is only able to give them simple commands.

Expert Swordsmanship: By throwing his head into the air, and suspending it, Beldia is capable of having a birds eye view of the battlefield. He can skillfully evade and counter attack any opponents caught in his sight.
