Romancing SaGa 3
The Professor can be found in her laboratory in the woods near Zweig. The first time the heroes meet her, she will make a dramatic entrance and sing about how wise and beautiful she is. After her show is over she will give the player a quest to retrieve her pets. They can be found outside her laboratory, and are all regular monsters with some sort of decoration. After this quest is done the player can talk to her to get a potion to weaken the rats plaguing Kidlanto.

Later in the game, a cutscene will play showing the heroes getting trampled by a car when entering any city near Zweig. If you talk with the Professor, she will give the player another car, triggering a unique boss fight against Natch Zweiger.
