Zelda Phiona Spellman is a character featured in the Archie comic book Sabrina the Teenage Witch.

Starting in the late 1990s, Zelda (and Hilda)'s appearances and personalities were revamped to make her more contemporary (as well as match the live-action sitcom's take on the character).

As a stark contrast to early comic portrayals, she plays a more prominent role than Hilda and insists that Sabrina only use her magic for good.

Zelda grew up during the 14th century in Europe, with at least five other siblings: Vesta, being the oldest; Edward, Hilda and Sophia, the youngest.

Their overbearing mother, Grandma Lydia, spent 200 years of violin lessons on Hilda, while Zelda won trophies, "Winner of the Other Realm Science Fair", "Outstanding Student of the Decade" and "Best of the Best".

When it became apparent that she would lose her job as associate professor unless she obtained a more recent degree, she completed a doctoral thesis in two weeks and earned a fourth PhD from Adams College.

In the early 1990s, before Sabrina came to live with Hilda and Zelda, they had manservants, spent late nights on the town, weekends in Tuscany, took part in Formula One racing, and originally had a disco on the second floor of their house.

During this time, Zelda became jealous of Hilda's relationship with the college president Wayne Banning (though not romantically).

Zelda was similar to her then-current comics portrayal, with a typical "witch" appearance and attire, as well as her good-natured personality.

She is depicted as a teenager (instead of the usual middle-aged adult), despite being the same age as in other media (hundreds of years old).

It is mentioned in passing that she and Hilda have temporally been changed into teenagers by head witch Enchantra as punishment for minor crimes, but the situation is never fully explained.

Unlike in live action series, In Uncle Quigley is the authority figure and head of the household.

Sabrina's Secret Life (set two years later), Hilda and Zelda are out of school and able to run the household (and Uncle Quigley is no longer in the cast).

Zelda is the more rigid of the two sisters, sometimes clashing with Hilda and Sabrina, however her filial affection overrules all other feelings.
