WonderWitch

• Type: Brand of magical products, primarily Love Potions
• Owners: Fred Weasley and George Weasley
• Maker: Fred Weasley and George Weasley

WonderWitch is a brand name for a line of products created and sold by Fred and George Weasley at their shop, Weasleys' Wizard Wheezes. The product line is specifically marketed towards young witches and is known for its flamboyant and glamorous packaging, which is typically bright pink. The primary products under the WonderWitch banner are powerful Love Potions, which were advertised in the shop as being “guaranteed-to-work”. The display for these items was prominent within the store, indicating their popularity.

The core function of the WonderWitch products is to induce powerful feelings of infatuation in the person who consumes them. As explained by Horace Slughorn regarding Love Potions in general, they do not create genuine love, which is impossible to manufacture, but rather a strong obsession that can be mistaken for it. The effects of the potions are temporary and require repeated doses to maintain the infatuation. The intensity and duration of the potion sold by the Weasley twins are not specified, but they were potent enough to be considered a “runaway success” and to cause significant, albeit temporary, obsession in a victim, as seen with Ron Weasley. It is likely that an antidote was also available for purchase, consistent with the twins' business practices.

The WonderWitch product line was developed by Fred Weasley and George Weasley sometime after they left Hogwarts School of Witchcraft and Wizardry in 1996. The brand was launched as a key feature of their joke shop, Weasleys' Wizard Wheezes, located at Number 93, Diagon Alley, upon its grand opening in the summer of 1996. The products, especially the Love Potions, became immensely popular among the students of Hogwarts, much to the disapproval of figures like Molly Weasley and Hermione Granger, who viewed the items as dangerous and unethical. Despite this, the commercial success of the WonderWitch line contributed significantly to the twins' burgeoning business empire.

The WonderWitch brand is introduced in Harry Potter and the Half-Blood Prince, showcasing the Weasley twins' entrepreneurial talent and providing a source of levity and commerce amidst the growing fear of Lord Voldemort's return. The products play a direct and crucial role in the plot when Romilda Vane, hoping to make Harry Potter fall in love with her, spikes a box of Chocolate Cauldrons with a WonderWitch Love Potion. Harry does not eat them, but Ron Weasley accidentally consumes the chocolates and becomes violently infatuated with Romilda. This forces Harry to take Ron to Professor Slughorn for an antidote. The meeting in Slughorn's office directly leads to Ron being accidentally poisoned by a bottle of oaked-matured mead intended as a gift for Albus Dumbledore, a critical event that deepens Harry's suspicions of Draco Malfoy.

• The name “WonderWitch” is a clear parody of real-world cosmetic and “wonder product” brand names. It also fits the alliterative branding pattern used by Fred and George Weasley for many of their creations (e.g., Skiving Snackboxes, Weasleys' Wizard Wheezes).
• In the film adaptation of Harry Potter and the Half-Blood Prince, the WonderWitch Love Potions are shown in elaborate, heart-shaped, pink-and-purple packaging, prominently displayed in the Weasleys' shop. (film)
