Camillo Carmine is a demon and one of the many powerful Overlords of Hell and is the ruler of Hell's weapons industry who is also arguably their leader as well as the one responsible for killing an Exorcist to protect his sons, Ali and Lance. He is the top weapons dealer of Hell.

Camillo is a tall and slender humanoid demon with a lean but muscular body type, light grey skin, and shoulder-length, thick white hair with a dark grey streak in his bangs. His hair is usually kept into a messy low ponytail held by a ballerina-like black ribbon, but with voluminous side-swept bangs as well as stray strands spiked voluminously, but layered on top of many other. His mouth has black lips and noticeable small fangs inside, and he has a marking colored in a darker shade of his grey skin tone resembling a mask that envelopes his eyes, which themselves have white irises, bright red sclera and black slit pupils. His thin arms and big hands are colored white that reaches from his deltoids down, with his hands being rather large in proportion to his body with black pointed claw-like nails. He also has bridged wrists, instead of the alignment of his arms narrowing at the wrists like most humans and demons. Camillo wore a dark-grey blackish turtlenecked bodysuit with an invisible zipper on the left side, which has a body-hugging texture, and up his legs and arms were very long neon white laces akin to a ballerina crossed over up his arms and legs. He often walked on the tips of his toes like a ballerina as well, in his pointé shoes, which are revealed to be made out of angelic steel. He also accessorizes with a set of black hoop earrings. It had been shown he uses his shoes as weapons as times as well, such as when he killed that exorcist.

Camillo appears to be largely professional, though he can lose his temper, especially when Zestia is insulted or his family is in danger. Zestia claims that losing his temper is usually very unlike him, indicating that he is usually calm and level-headed. He loves and cares about his two sons, willing to cross any line to protect them, even if it means killing an Exorcist Angel while knowing there will be disastrous consequences for it. He even cares about his fellow overlord, Zestia, willing to protect her too. He wants to avoid resorting to violence and avoid going to war, but at the same time, he'll do whatever it takes to protect his loved ones. He refuses to help Vaggie join Charlie's war against the Exorcist angels due to the fallout threatening his sons' safety, but he does have a sense of pride when he demonstrates to Vaggie the weakness in the exorcist angel's fighting style as well as motivates Vaggie to "fight for love".

His eyes can glow when feeling strong emotions, particularly in dark environments. He has enhanced kinetic balance, allowing him to walk on the tips of his toes for long periods without faltering. He also has enhanced agility to where he can actually do a full splits against a wall and in the air if he wanted.

The Extermination was finished, and that Hazbin Hotel won. With Rosie’s cannibals and Camillo’s weapons, it all panned out correctly. However, what happened before that kept replaying in his head.

Velvette. Fuck, he couldn’t stand her at times, but he loved her. After all, they were married, in secret of course. For appearances on one note.

Only Ali and Lance, Camillo’s sons knew about the marriage. After all, they were actually Velvette’s sons as well, biologically. They’d been married for a while, and sometimes when Camillo was too busy, they would go to Vee Tower and spend time at Velvette’s job.

It was a good marriage. One day, Camillo was in his office working. Then, somebody walked in without knocking. Camillo looked up, his gaze narrowing slightly, probably to say something about kno before his gaze fell onto Velvette.

"Muñeca…" He spoke in his native language, before he spoke again, keeping professional. "What are you doing here?" He asked, leaning back slightly in his chair, waiting.

This better be interesting…
