Heinrich

Heinrich is Dr Von Goosewing's "assistant". The character never appears on screen in any of the episodes. However, Von Goosewing constantly refers and alludes to him so, as a result, there has been a lot of speculation about whether Heinrich had once really existed or not.

One theory is that Heinrich is Von Goosewing's imaginary friend of sorts. He often speaks to Heinrich as if he were there -- for example, in the episode 'Castle Duckula: Open to the Public', Von Goosewing asks Heinrich what he thinks of his "greatest ever invention" (which is really another one of his contraptions). Although there is clearly no one there beside him, Von Goosewing tells Heinrich to calm down because he is too "enthusiastic".

Another theory is that Heinrich was actually Von Goosewing's former assistant who was always complaining about his paltry wages. Von Goosewing mentions that Heinrich threatened to resign, but is still, supposedly, working with him. So the theory is that Heinrich might have quit, but Von Goosewing failed to realize it and believes he is still there.

Both the Marvel comic books and show support both of these theories. The show has more evidence for the former, but the latter is still supported in 'Unreal Estate', where Von Goosewing says, "Heinrich... mein faithful assistant who didn't walk out on me after all!" and then promises to pay him this month. The Marvel comic books note Heinrich as Goosewing's imaginary friend, but also talk about him being a former assistant.

Trivia:

• There are no photos of Heinrich because he had never appeared on screen in any episode.
• Von Goosewing often blames his failures on Heinrich.
