Blendin Blandin

There is a hidden mystery man who appears in almost every episode. When he does make his appearance, it is only for a moment. It is unknown who he is or what he does, but most fans suspect that he is a time traveler and/or the author of the series of hand book that hand books 2 and 3 are from. He also appears in the theme song opening.

Character History
He was first seen hiding in the bushes when Dipper and Mabel were being attacked by the gnomes. Later, he was seen picking up an object when Old Man McGucket was screaming that he saw The Gobblewonker. This object looked similar to a tape. He was amongst the crowd when Grunkle Stan was unveiling his wax figure. When Old Man McGucket was asking his question, the mystery man appeared to be holding a shoe and he quickly ran off screen. The shoe was identical to Dipper's. His photograph was also seen on Dipper's list of suspects board. While many fans say he is the author of the books, in the theme song his photo appears with Lil Gideon and other villans.Therefore he is most likely evil.

Physical appearance
He is a heavyset, dark skinned man, and is bald. He wears goggles and some sort of uniform.
