Guillermo, expertly played by Harvey Guillén, is Nandor's familiar who just wants to be turned into a vampire like his master. After 10 years of being his faithful servant, Nandor gifts Guillermo with a glitter-painting, which is more than Guillermo usually gets. Guillermo typically has to clean up after Nandor, Lazlo, and Nadja's shenanigans, including burying a sh*t ton of bodies in their backyard. Without him, the group would fall apart and he's STILL treated like dirt. Everyone can relate to Guillermo in some way or another, whether a friend has taken you for granted or a boss hasn't shown you appreciation. It isn't until he leaves Nandor for another vampire that he gains any power in the group.
