Pancho Addams is a relative of The Addams Family.
He is Gomez's younger brother, who once courted Morticia. Pancho told Wednesday Jr. and Pugsley Jr. about the tale of Cousin Shy. Gomez had trouble getting along with him when he came over to help with the family's Halloween celebration because he didn't want him usurping his traditions and he also still had some affection towards Morticia.
Eventually, Gomez learned to get along with his brother.
Pancho only appeared in the 1977 reunion special Halloween with the New Addams Family.
