Hades

Appearance
Hades is very tall, with broad shoulders and a long, sharp nose. He has sky-blue skin and ivory-white hair with blue highlights. He usually wears his hair short, but in the Mortal Realm he lets it grow long. His eyes are black, and his irises often change color depending on his mood (usually red). When he becomes angry, the whites of his eyes turn dark red. He has a muscular physique, and several white scars crisscross his upper body. Persephone also notes that he has dimples.

In the Underworld, Hades usually dresses formally, in black suits, trousers, and a white button-down shirt with a sable tie. For warmth, he typically wears a black overcoat. For sleep, he might wear anything from an Underworld Con '96 hoodie with black sweatpants to just his underwear.

In the Mortal Realm, Hades wears long Greek robes of dark blue and gray.

In her human form, she has brown skin, amber eyes (which turn red when she's alert), and long, creamy-white hair. She wears a short chiton with blue fabric draped over her arm and crystal brooches on her shoulders and sandals, and a pointed black crown.

In his true form, Hades's eyes, pupils, and eyebrows change from black to a bright, light blue. His skin also turns a much darker blue, and "stars" appear. In his Titan form, he retains his true appearance, but his hair becomes long and dark blue, and his hands transform into claws.

Personality
Hades' reputation paints him as a dark ruler, so feared by mortals that they refuse to call him by name, referring to him only by his aliases. In reality, Hades is polite, sensitive, and often melancholic, as he did not choose the Underworld for himself. Nyx tells him that she "never saw a child with so many worries," a personality trait that, coupled with the trauma of being devoured by Cronus, led him to become an adult with low self-esteem. Despite his brother Zeus' assurance that becoming King of the Underworld would not affect his relationships, after taking control of the realm, Hades frequently isolated himself from others, leading to misunderstandings about him. Currently, Hades remains isolated, with few true friends and convinced that he deserves the toxic relationship in which he is trapped.
Hades is kind and understanding to those he cares about and behaves like a gentleman compared to the rude and lecherous behavior of his brothers. However, his dark reputation is not just a rumor. He does not hesitate to inflict cruel punishments on those who offend him and views the shades under his care as a constant source of unpaid labor. Like most gods, Hades feels little sympathy for mortals.
He has a toxic relationship with Minthe.

Minthe is a river nymph with scarlet skin, straight, dark red hair, and long, pointed ears. She is tall, slender, and curvaceous, usually wearing black or dark red clothing.
