Velvet

Velvet, also known as Baby Doll, is the villainous protagonist of the film Velvet. She is an unhinged doll demon with a penchant for kidnapping sinners, bringing them to the Circus of Hell to be tortured for the amusement of both her and her followers, then murdering her victims for sadistic pleasure, or using potions to turn them into sentient dolls and using them as her personal playthings.

Personality
Velvet is a hyperactive, talkative, and childish serial killer who was famous for being one of the most deranged and unpredictable demons. She had a penchant for kidnapping sinners and torturing them for her amusement, typically as a part of a circus she runs called the Circus of Hell. After she has her fun tormenting and mutilating her victims, she either have them sent to The Sweet Spot to be baked into confectionary treats for herself to eat, or transforms them into sentient dolls with potions so that she can use them as her own personal toys, which is widely considered by the denizens of Hell to be a fate even worse than double death.

Velvet has a complete addiction and obsession with social media; she is constantly seen on her phone, takes selfies of herself and others on a whim (sometimes even posing with the corpses of her victims), and has a habit of livestreaming the torture and murder of her victims to her followers. She is very narcissistic and self-obsessed, only ever seeming to care about getting as many followers and likes as possible, and completely disregards the lives she has killed and ruined as long as it means getting more attention and publicity.

As a killer, she is exceptionally merciless, unfeeling, and extremely sadistic; she has no qualms with forcing her victims to watch as their own friends or family members were killed, and displays no outward remorse for her crimes whatsoever, going as far as to mock her victims' family members by calling and telling them about how she killed their loved ones in detail for the sake of recording their reactions.

Her methods of murdering are also exceptionally brutal, including vivisecting her victims, cutting their organs out, and skinning them alive. After killing them, she often has her victims' corpses converted into attractions for the Circus of Hell, such as making a jack-in-the-box out of their stretched out bodies, or tying her victims' bodies to strings and using them as marionettes.

She possesses a lively, bubbly sense of humor, and constantly cracks various jokes in any situation, but more often while tormenting her victims and causing general mayhem, as such, she is shown to be carefree, energetic, and rather air-headed.

Regardless of her cuteness, Velvet is still a very real and dangerous threat to others, and can easily be cruel and devious.
