Mz. Hyde

Mz. Hyde is a term, a play on the name Mr. Hyde from Robert Louis Stevenson's novella Strange Case of Dr. Jekyll and Mr. Hyde, often used to denote a female character or person who exhibits a marked duality or transformation of personality, typically from a polite or well-mannered demeanor to a more aggressive, sinister, or otherwise undesirable one. The term is used colloquially and in fiction to quickly convey a shift in character, implying a hidden, darker side. The "Mz." prefix is used to denote a woman without specifying her marital status, further emphasizing the ambiguity and potential for hidden identity inherent in the "Hyde" aspect of the name.
