Nightmare Fuel: The Great Mouse Detective
Ratigan during the final confrontation in the clock tower. His clothes are torn, he's given up all pretenses at civility, and at several moments is scurrying about like a real rat. And it is terrifying.
And it's pretty scary when he lunges towards Basil when Basil is trying to get Olivia to Flaversham. It almost seems like he's lunging at the audience rather than Basil!
