Hilda Spellman is a character featured in the Archie comic book Sabrina the Teenage Witch. Hilda is a full witch (as opposed to half or fully mortal) who lives in the fictional town of Greendale (in the 1990s live-action sitcom, Hilda lives in fictional Westbridge, Massachusetts). Hilda lives with her niece Sabrina Spellman, sister Zelda Spellman, and the family cat Salem, a former warlock turned into a cat as punishment for his attempt at world domination.
Hilda debuted as "Hilda the Witch" in Archie's Mad House #19 (June 1962) as an ugly witch with dark hair and green skin. She was featured throughout the series in solo stories, as well as the "host" of the comic book (in a role similar to the Crypt-Keeper from the Tales from the Crypt comic book series). During her early appearances in Archie's Mad House, she was not connected to the Sabrina stories. However, a prototype of the "Aunt Hilda" character named "Greta the Fairy Witch Mother" (who debuted in Archie's Mad House #28 and was similar in physical appearance to Hilda the Witch) appeared in early Sabrina stories. Eventually, Hilda the Witch and Greta the Fairy Witch Mother evolved into the Aunt Hilda character in Archie's Mad House #37 (although the Greta character reappeared one last time in Archie's Mad House #45).
Upon becoming Aunt Hilda, the character was depicted as a tall and thin Caucasian woman with red hair. She tended to be short-tempered and more prone to acting like an evil witch. She was the more prominent of Sabrina's two aunts, appearing in more stories than Zelda. In one story, she was stated to be seven hundred years old. Hilda's wardrobe was that of a traditional/stereotypical witch.
Starting in the late 1990s, Hilda's (and Zelda)'s appearances and personalities were revamped to make her more contemporary (as well as match the live-action sitcom's take on the character). In modern stories, Hilda has her trademark orange hair, but appears to be only physically a few years older than Sabrina and dresses in modern fashions.
