R. Dorothy Wayneright

"You're a louse, Roger Smith."

- Dorothy's catchphrase R. Dorothy Wayneright, usually known simply as Dorothy, is the deuteragonist and lead heroine of the anime series The Big O. She is an android created by the scientist Miguel Soldano, as commissioned by Timothy Wayneright. She moves in with Roger Smith after he saves her, becoming his personal assistant and often accompanying him on Negotiator missions.

She is voiced by Akiko Yajima in the Japanese version and Lia Sargent in the English version.

Appearance
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, due to her body being mechanical. At Roger's insistence, she wears a black dress with a white collar, and thigh-length black tights with black shoes.

Personality
Being of a mechanical nature, Dorothy is withdrawn, stoic, and cold. She is described as being "perpetually foul tempered" and at times can be extremely sarcastic, despite her insistence that she was programmed without the ability to feel emotions. While she tends to speak in a monotone whisper, there are times in which she has become visibly angry. Dorothy is also very insecure about her robotic nature: for instance, she refuses to board an elevator with a strict weight capacity due to the fact that it reminds her that she is merely a "copy" of the original Dorothy Wayneright. Despite her sarcastic nature, Dorothy is a very straightforward person who can get along with just about anyone, even those she harbours suspicion towards.

Ironically, while she can pass as human under cursory inspection, Dorothy is the least "human" of any android seen throughout the series, as the rest are all shown to be capable of experiencing and expressing emotions. With the revelation that R. Dorothy possesses the original Dorothy Wayneright's mind, it is also implied that Dorothy's reticent behavior comes from the shock of her grandfather's death, which is indeed a very human reaction to have.

Dorothy complies with some of Isaac Asimov's 3 laws of robotics, but not all. For example, she is incapable of knowingly and willingly harming a human target, though if she is tricked into thinking that they are not human (whether by themselves or another), then she is capable of inflicting harm upon said target. Dorothy, while "obedient", also has a penchant for passive aggressiveness and deliberately acts inhuman to get a rise out of her master, whom she often refers to as a nuisance with her catchphrase, "You're a louse, Roger Smith".
