Count Duckula make Duckula harmless, but he turns away from the door when he discovers that the sun is still out and is returned to normal by night. Although he is often egotistical and selfish, Duckula is good-natured, often trying to help people, although he usually succeeds only in making them hate him. He is prone to short-lived obsessions, often forming the plots for episodes, such as attempting to become a blues musician in New Orleans, prospecting for gold, or becoming a cowboy or performer. The character differs considerably from his predecessor on the "Danger Mouse" series. In fact, the only similarities,
Count Duckula often getting maimed by his own crackpot inventions, he is supremely unobservant, and often bumps into Duckula and converses with him for several minutes without realizing to whom he is speaking. Von Goosewing appears to have an assistant named Heinrich (who never appears on screen). Von Goosewing often calls for Heinrich, and often blames his failures on him. In fact, "Heinrich" appears to be just a figment of Von Goosewing's imagination, an imaginary friend. However, the comic book version of the characters by Marvel reveal that Heinrich is actually his former assistant who is always complaining about his paltry wages.
