Dejah Thoris is the wife John Carter crosses a hostile planet to reclaim, and her captivity drives the novel's pursuit. When she mistakes Carter for a stranger in disguise, her righteous fury reveals both her pride and the depth of her devotion. Facing Salensus Oll's jealous demands, she refuses to trade her husband's memory for a throne, declaring she would rather be a slave beside such a man than queen of Okar. Her public defiance raises the stakes of Carter's rescue and anchors the story's moral center.
