Hecadoth

is Pillar General 8 of Behemoth's 34 Pillar Division. He is the first Demon from the the aforementioned Division to fight against Oga.

Appearance
Hecadoth is a tall, well-toned man who stands at least a head taller than Oga. He also wears typical Pillar General clothes, albeit more formally, and has the unique fin-like ears that all members of Behemoth's 34 Pillar Division possess. And as such, he has also a distinctive tattoo on his face, common for Pillar Generals.

When first imprisoned, he was shown wearing plain clothes and his face was somewhat unshaven. Upon his release, his face became clean and he wore his regular clothes again, though after he was defeated by Oga and imprisoned for the second time, his appearance reverted back to its former, shabby self.

Personality
According to Graphel, Hecadoth is the kind of person who likes looking down on his opponents. Hecadoth appears bloodthirsty, cruel, and even sadistic; these traits were obvious from his first appearance in the series. He is also aggressive and rather cocky.

History
Though not much is known about his past, he was promoted to Pillar General at some point in his life.

Prince En Arc
He begins his attack on Oga and the others by imprisoning Kunieda with the intention to use her blood to forge a demon contract; it is understood that the already powerful demons increase their power in the human world considerably if they find a contractor. It seems that the contract itself is not necessarily consensual. However, Hecadoth looks down on Hilda and Oga and, instead of proceeding to seal the contract, he allows them to have a shot at him. The two succeed in surprising him with Oga's Zebel Blast, while Hilda releases Kunieda. Hecadoth, who had planned for that, uses the opportunity to impale Hilda with his spear, putting her out of combat. He then proceeds to face Oga, and is only prevented from killing him by Saotome's intervention, whereby he is sent back to the demon world. His spear fails to kill Hilda thanks to Kunieda's first aid and Dr. Rachmaninorr's timely intervention, but it puts the demon maid out of action for some time, since it has the property of diffusing demonic powers around the wound.

Later, Hecadoth meets Hilda again, but this time she is at the top of her powers and unhindered, and attacks him fiercely. Before he can retaliate, Oga arrives from his training with Saotome and takes up the fight from Hilda. He defeats Hecadoth easily and the demon is the first victim of the Zebel Emblem.

Akumano Academy Arc
Later during Oga's raid at the Akumano Academy, Hecadoth is seen in prison with Graphel. He commented on how Oga told him that he will destroy Behemoth's squad but he never thought him to be so stupid as to attack all of them by himself.

Powers & Abilities
Hecadoth is a Pillar in Behemoth's 34 Pillar Division, depicting that he is stronger than a normal human and an ordinary demon. He was able to easily overpower Oga and defeat weakened Hilda in their first encounter. Though he was easily defeated by Oga after his training.
