People believe that Gaster is family with Sans because besides Papyrus,Gaster is the only other character implied to be a skeleton and without mentioning that Sans has blasters called "Gaster blasters"and Toby fox said that the skelebros had another redacted relative.So It's understable why people depict gaster as his relative.The real question is why Gaster is ALWAYS depicted as the skelebros father instead of brother,grand father etc...Why people are so obsessed with this trope
