Dorothy is quite durable and much stronger than any human, able to punch down a brick wall with one blow or leap several dozen feet into the air. She has amazing balance, as seen during her moments of contemplation while standing precariously on the edge of Roger's balcony. R. Dorothy can run or bicycle at superhuman speed and does not require oxygen to operate. She shows superhuman coordination, performing effortless gymnastics and is able to steer a car with her foot while standing on the hood. That she takes regular meals with Roger indicates she can consume food and beverages, although she admits in episode 11 "Daemonseed" not being able to taste. Dorothy also seems to have an unexplained connection to Big O itself. In eps. 20 and 21, when Dorothy is nearly destroyed by Alan Gabriel, Big O apparently senses this and shuts down in order to facilitate her rescue by Roger. In the final Act, she activates Big O's Final Stage weapon by plugging herself directly into the megadeus. She shows self-awareness and capacity for learning; throughout the series she exhibits talents at performance singing and virtuoso piano. It's suggested that the show's closing song "And Forever" is R. Dorothy performing with a male vocalist, who may or may not be Roger. (In episode 8 "The Missing Cat" she can be heard humming it.)
