Dora's personality is somewhat unknown because her dialogue is her repeatedly saying "Dadadada". Despite this, she can be seen as a calm and collected individual, not causing conflict, and somewhat introverted. Four can understand her for some reason which is yet to be explained. In contrasts to David speaking fluent English but having limited speech, Dora has a much more extensive and eloquent vocabulary, implying that Dora has a much more sophisticated personality than David. She is a female.
