Stanley "Stan" Gleeful, an antagonist of Reverse Falls, is the relative (great uncle or gruncle) of Dipper Gleeful and Mabel Gleeful. Some say that Stan doesn't have powers, but it is not confirmed yet. Stan may or may not have a wife. If Stan does have a wife, it is likely Reverse Lazy Susan.
Appearance EditStanley wears a pink Hawaiian shirt and a farmer's hat. Some illustrations include him in a light blue suit with a turquoise crystal.
Like the twins, Stan is also mean and deceitful. While he is deceitful in Gravity Falls, Stan in Reverse Falls will act nice in public; in reality, like his great niece and nephew, is sadistic and enjoys killing. He watches over the twins torture and kill their victims and doesn't stop them.
Dipper and Mabel Gleeful Edit
His relationship with his great niece and nephew appear to be really good. He doesn't stop Dipper and Mabel from killing; he rather enjoys it, he enjoys torturing Will with the twins, and he is their partner in crime in the Tent of Telepathy. He is cruel like the twins and watches over them when they kill and smile.
He does love them and is proud of their evilness.
Stanford Gleeful Edit
Stanley's relationship with his twin brother seems to be better than the Stan Pines twins.
