Beel Bub

"The beautiful bloody fireworks of gray matter and entrails bursting out. Truly a sight to see, indeed."

- Beel Bub commenting on the slaughter

Beel Bub is a anthropomorphic fly demon that serves under the Demon Lord as an airborne shock troop leader commanding army of Aerial Assault Flies.

Appearance
He is a giant anthropomorphic fly. He has dark skin and long limbs, along with giant red facette eyes. However he does wear black pants and brown shoes. On his knees and belt, he also has spikes.

Personality
Beel Bub is cruel, merciless, and kills with no remorse. He sees himself and his flies as superior to humans. He has extreme speed and agility. He also has a twisted sense of sadistic humor. He is cautious (not as much as Seiya though) and analytical, as shown when he quickly assesses the situation of an arrow being shot at him despite being way out of range for a surface-to-air attack.

History
Beel Bub is first seen slaughtering Roseguard soldiers mercilessly with his fly soldiers in an attempt to lure the hero out. Under the Demon Lord's orders he attacks Olga castle with his army of more than 300 demon flies, he calls the Aerial Assault Flies. He gathers near a giant tree and his swarm of flies look like dark clouds. He tells the humans to bow down and then manages to avoid all of their arrows. His flies then pick up a lot of soldiers into the air. Beel Bub tells them to start the reverse fireworks, with which he means the bloody explosions of the soldiers falling to their deaths. He laughs, but still looks frantically for the hero, Seiya. He doesn't destroy the castle entirely since he only wants to draw the hero out. Beel Bub then retreats to his lair for the meantime.

Later the knight Rosalie attempts to fight him, but gets quickly lifted up. Beel Bub decides to fly as high as he can and then drop her from that height. Ristarte catches up to him, which alerts Beel Bub that Seiya is also around. Since he might get shot with an arrow, he flies higher until he is above the clouds. There he wants to drop Rosalie but is streaked by an arrow of Seiya. Ristarte manages to catch Rosalie and then Beel Bub storms towards him. He has studied human magic and calculated that they would never be able to harm him at this height. He dodges all of Seiya's arrows. But Seiya learned a skill, which transforms arrows into magic birds. Beel Bub couldn't possibly predict that and is shocked. The birds pierce through his chest and kill him.

Powers and Abilities
While his physical and magical stats are by no means low, his true strength lies with his speed, even claiming that his speed is 'on another level'. Another one of his most potent abilities is his skill of flight. While the skill of flight is something more monsters possess, none do it as efficiently and deadly as Beel Bub. He is physically strong enough to carry armored humans high in the sky with no trouble at all.
