Dorothy stands just under 5 feet (150 cm) tall, has red hair, chalk-white skin and much more body weight than her slender appearance reveals (about 130 kg or approximately 287 lbs.). Her dress is a size three and forehead houses an illuminated CD ROM drive, which is loaded from a drawer made to resemble a hair ribbon. While capable of normal human facial expression, in film-noir tradition she typically maintains a pouty contour and a mildly sarcastic personality, described by Angel as being "perpetually foul-tempered". Her dry wit is best reflected by her catchphrase "You're a louse, Roger Smith," her teasing response to Roger's sometimes unreasonable demands. She and Roger maintain playful retorts throughout the series, with Dorothy often going out of her way to irritate Roger or otherwise rattle his cage. Regardless, she has shown hints of romantic feelings towards Smith. Offsetting her straightforward attitude is her general likability; she gets along rather well with virtually everyone, even those with whom she harbors suspicion. From her conversation and behaviour, it is evident that Dorothy has the capacity for human emotions. She has shown genuine fear on a number of occasions, and reveals jealousy toward Angel's relationship with Roger and satisfaction from its failure to become romantic. An annoying habit (at least to Roger) is that she plays the piano loudly when he oversleeps, mostly due to his late nights on the job.
