Damocles

He is father of Tohru and Emperor of Demise.

Appearance
In his human form, Tohru's father takes a form of a short old man covered with a dark red cloak (black in some occasions), he has long grey hair and a long grey beard, he also has grim-looking eyes.

In his true/dragon form, which is only revealed in the anime, he is a large dragon, almost similar to Tohru but with a lot of different features, he is a bit bigger, almost a bit bigger than Tohru herself, and bulkier as well, his scales are red with a pale brown color underbelly, he has 6 horns, 2 long whiskers, red eyes, a long white mane, and sharper wings, his most notable feature is the fact that his overall design is a mix between a Japanese dragon, and a European dragon

Personality
Tohru's father is callous and stern, hating humans and viewing them as inferior and evil - a belief he tried to impart on Tohru. However, unlike other Chaos Dragons, he is respectful of the non-interference laws preventing dragons from killing humans of Earth, although when angered, he attacks Kobayashi and threatens to leave her at the brink of death. Despite this, he cares for his daughter and is concerned for her safety, warning her that the peaceful human life she claims to want is impossible, and that her presence risks bringing the Chaos Dragon vs. Harmony Dragon war that is ravaging the Other World to Earth.

Tohru
Though he is very caring of his daughter, he was immediately appalled and angered upon seeing her daughter defect to the other world and affiliating herself with a human. At one point, he took Tohru back into her world, only for her to come back to the other world and confront her and Kobayashi at her defiance.

Powers and Abilities
His is, arguably, the strongest dragon in the series so far, nearly rivalring Tohru in terms of strength and magic power, not even flinching after taking hits from her. He eradicates a vase nearby Kobayashi in the manga (in the anime, her glasses are snapped in half instead).
