Joan the Maid is an infantry hero in Age of Empires II. She is available in the Scenario Editor and makes one campaign appearance, in An Unlikely Messiah, the first scenario of her campaign. In later scenarios, she is replaced by her mounted variant. As a hero, she cannot be converted and can regenerate health.
Joan the Maid is the only human unit in the original game that doesn't change color depending of the Player; she is dressed in a brown and black dress no matter what. The Scythian Wild Woman in Age of Empires II: The Conquerors reuses the model, but has a different icon.
