This is the opposite of Germans Love David Hasselhoff: A character or entertainer who is fairly popular in one region becomes The Scrappy in another market. The most common reason for this is usually Values Dissonance, as things that seem normal or relatable in one culture can be seen as offensive, baffling, or just plain stupid in another. Another reason for it can be that a character is supposed to represent the nation that hates them, and this character is seen as offensively stereotypical. In the worst cases, the hatedom of a single character can result in No Export for You for an entire series (something some people are probably going to be grateful for).
