Greg's Uncle Charlie is described by Greg as being able to get him anything he wants for Christmas or his birthday. Ironically, the few times throughout the series that Uncle Charlie brought Greg gifts, he is only disappointed by what he brings. A few examples are a Barbie Beach Doll, a picture of him, and Wonder Woman Underoos. In book 4, it's said that he has a recliner which "he practically lives in." In the visual novel, he is named Freddie.
