Giantess Niffty

Appearance: Niffty is a small and slender, cyclops demon with pointed limbs, white skin, and one large eye. Her eye sports a light yellow iris, thick eyelashes, a hot-pink sclera with a yellow gradient, and a large pie eye-cut pupil. When feeling homicidal, her pupil shrinks and her eye gains black veins.

Her short chin-length red-pink hair is kept into a slightly messy and choppy 1950s bob cut with a curl on each side, and a single light yellow streak located at the top. Her mouth has sharp light pale yellow teeth inside and black lips, and small hot-pink dots on each of the corners.

Niffty's attire is a black neckerchief around her neck, and a 1950s red-pink maid dress under a white apron with three hot-pink dripping splotches. She also wears long black gloves which covers most of her hands and arms, along with matching-colored tights.

Pilot In the pilot, her skin was light yellow and her hair appeared scruffier, with the single streak instead being a shade of amber. Her lips were also maroon.

Her attire, while still 1950s-themed, instead consisted of a burgundy neckerchief, a short-sleeve white blouse with three hot-pink dripping splotches and a 50s-fashionable red-pink swing poodle skirt which featured a dark burgundy poodle with yellow dots. Her gloves and tights were instead the same color as the poodle print on her skirt.

Personality: Niffty is hyper, spontaneous, partly sadistic, and agile, being very quick on her feet. She is easily entertained, easily distracted, and easily excitable. She dislikes when there is a mess in any room, and has a fixation on men in general.[note 1]

However, she appears to only like "bad boys", including a brief obsession with Sir Pentious. This ends in her kicking him in frustration after he apologizes and decides to seek redemption at the Hotel. She isn't afraid to get dirty, and enjoys cleaning everyone's messes with a gleeful, yet creepy charm.[8]

She becomes very focused on things she is ordered to do, such as in "The Show Must Go On" when she was told to stab angels and obsessively stabbed every angel she could, including Adam, whom she managed to kill. She had also briefly attempted to stab Angel Dust when Charlie asked Niffty to stab angels (referring to Heaven's angels) if she sees one before the battle. When interviewed for 666 News, Niffty told them that "Charlie told me to stab, so I did".

She is shown to enjoy violence, as she was very ecstatic to be thrown into a warzone as part of Vaggi's trust training, and afterwards stated she enjoyed when Sir Pentious was being hit with a severed arm. Despite all of her twistedness, she does have some kind of standards for how she views who is "bad" as she outright berates Sir Pentious for not being a bad boy when he was apologizing for trying to spy on everyone.

She appears to have masochistic tendencies, shown when she liked the pain from falling off a stage within the Hotel and then repeatedly jumping off. She is also implied to be sadistic, stating her desire to "punish" people in a BDSM dungeon. She even outright states that she kills mother bugs in front of their baby bugs as a form of lesson. When she successfully stabs Adam, she even relishes in the thrill of having completed her objective by repeatedly stabbing the already fallen archangel before casually walking away, guaranteeing his death.

She is also shown to suffer from what is assumed to be severe camera shyness, as whenever a camera begins filming her, she goes into a state of hypnotic trance where she doesn't move, blink, or speak, instead just staring at the camera until recording is done. She can, however, overcome her camera shyness if she believes the camera as a "big roach".

Niffty has an extreme hyper-fixation on cleanliness, constantly cleaning the Hotel and possesses a keen obsession with ridding any bugs and pests she sees to the point she would bring out a knife just to kill them. Even when taken outside of the Hotel, she constantly attempts to clean any mess, even in the sex club Cherri Bomb takes her and the other staff and residents to for drinks, where she attempts to steal cleaning supplies from a storage closet. She also does not take well to being insulted, such as when Angel Dust calls her a mess for her obsessive cleaning and attempted theft of aforementioned cleaning supplies, she breaks down crying until Angel calms her down.

She collects things from men she is obsessed with, such as when she tore off a piece of Valentino's collar fur to keep for her "collection".

In the pilot, she was shown to have traditional and stereotypical view on gender roles, which she is aware are potentially offensive. This also may have been seen in her fight against Velvette, where she taunts her with "You hit like a girl".

Despite her own traits, in her own song Clean It Up!, Niffty says that she actually believes in Charlie's redemption project, and despite considering sinners as assholes and complete "trash", she genuinely believes in the dream and loves working at the Hotel, thinking of Charlie as a rather nice boss.
