Pearl Douglas is a fictional character from the X film series, played by Mia Goth. Pearl first appears as the main antagonist in X (2022) and returns as the villainous protagonist and title character in its prequel, Pearl (2022). She is mentioned in the third film, MaXXXine (2024), and appears in flashback sequences. In X, Goth was cast as both Pearl and the final girl, Maxine. Director Ti West explained that this was to display the similarities between the two characters and admitted that a dual role for them was intended from the beginning, as he looked at them as "different characters but the same person". Goth commented that she gained many interpretations of Pearl's character throughout production, and felt sympathetic towards Pearl in X. The actress noted she preferred to think of her character as neither a villain nor a victim.
