Beel Bub

Beel Bub is a fly demon that was a leader of an army of fly monsters.

Appearance
He is a tall and lanky humanoid with many fly-like features.

Personality
Beel Bub is cruel, merciless, and kills with no remorse. He will kill his hostage as soon as they are no longer useful. 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. Having failed to lure him out, he returned to his nest. Later, Rosalie Roseguard shows up at his hideout, whom he takes hostage to once again try and lure the hero out to fight him. He flies high with her since his speed would give him an even greater advantage in the air, but he falls to a surprise attack by Seiya involving arrows that turned into birds once they missed and struck Beel Bub in the back.

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 with 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.

Trivia

 * His name is a reference to Beelzebub, a Philistine god often nicknamed "The Lord of flies".
