Lisa Lionheart was designed to provide a more positive role model for young girls, placing it into direct competition with the Malibu Stacy line of dolls. Fearful of what could happen to Malibu Stacy if Lisa Lionheart is a success, the managers(the men responsible for having instilled sexist wording for the doll) tried to stop Lisa's Pro-Feminist campaign against them. They attempt to threaten her with lawsuit, but Stacy Lovell, the creator of the Malibu Stacy franchise who had been removed for from the company for ideas that weren't cost effective and for funneling profits to the Vietcong, threatens to counter-sue them. The managers meet Lisa and promise to let her renovate Malibu Stacy into the nineties as a fashion forward and positive role model for little girls if she stops her production of her own doll. However, she sees past the managers attempts and refuses. She knows that anything they have Stacy say and do will always be sexist. Lisa's opinions are supported by original creator herself, Stacy Lovell who called out the men for removing her from her beloved position as owner and is also fed up with the way they have been making the doll she created into being a dumb and sexist twat. The managers then must try to come up with a way to sink Lisa Lionheart.
After seeing the news with Kent Brockman on it praising the Lisa Lionheart doll with his own daughter playing with another one, the desperate creators try one last ploy to sink Lisa Lionheart. When the Lisa doll was first released, all the young girls -- as well as Malibu Stacy collector Waylon Smithers, who yelled: "I want it, I want it, I want it!" -- were after it. However, before they could reach the Lisa Lionheart display, they were literally intercepted in the store by a cart of talking Malibu Stacy dolls with new hats, leading to the complete failure of Lisa Lionheart. However, Nina was the only one to buy one and Lisa is able to hope that one. Behind Lisa's back, Lovell had invested $46,000.00 into produced the Lisa Lionheart dolls, suggesting they were overpriced to cover production costs.
She has blonde hair in a ponytail and red lips. She's usually been seen wearing a lighter blue T-shirt, black jeans with a red belt, and black slip-on shoes with a pair of socks.
The Lisa Lionheart doll appears in the video game The Simpsons: Hit and Run as a collector card in level 3.
