Bob
A spirit of intellect bonded with a human skull, Bob has been assisting wizards as a living encyclopedia of magic for centuries.
Where is he from?
Bob is a character in Jim Butcher's ongoing urban fantasy series The Dresden Files.
Like Harry Dresden, Bob appeared in 2007 in the single-season SciFi tv series The Dresden Files. Here, he was depicted as being able to manifest a sort-of ghost body played by Terrence Mann. While I'm sure this was added to punch up the visual storytelling, it removed a lot of the humor from the character. Bascially, Bob and the rest of Harry Dresden's universe is bese seen in the Dresden Files novels.
