2B's appearance as an android appears to be that of a young woman with a pale complexion and she has a slim figure. She appears to have a mole on the right part of her chin. She has short, silvery white hair and is revealed to have grayish-blue eyes but is covered with her blindfold. 2B is a blade of quiet determination and she has a partner, 9S, that looks quite like her but is just the opposite gender.
