Gabby Gabby

Gabby Gabby is one of the characters in the 2019 Pixar film, Toy Story 4. She is an antique doll with a broken voice box, whose primary goal was to have it replaced by Woody's, so she could be loved by Harmony. As of now, she is owned by a little girl who was lost in the carnival.

Though initially the antagonist, Gabby Gabby has underlying reasoning for her actions, rather than for malicious intent. Trapped in an antique store with nothing but mute "dummies", she gets lonely and her honest desire for friends is what drives her motivations.[1] She is polite and well-spoken to visitors, even engaging in conversations with them, as shown when she discusses with Forky about Woody's past. However, due to her creepy and bitter demeanor, many other characters such as Woody and Bo Peep would pass her off as being "crazy".

Gabby Gabby is a Chatty Cathy doll with strawberry blonde hair in pigtails, blue-grey eyes, and freckles on her face. She wears yellow attire, including yellow hair bows, yellow Mary Jane shoes, and a yellow sundress.

Unlike Lotso and Stinky Pete, Gabby Gabby isn't a ruthless tyrant despite being the main antagonist.
While Gabby Gabby is shown to have reformed at the end, Lotso does not reform at all and it is unknown if Stinky Pete does.
Like Stinky Pete, Gabby Gabby was initially never owned by a child, waiting years before being owned. However, Gabby Gabby merely had a defective voice box, unlike Stinky Pete, who wasn't sold due to the rising popularity of space toys (which he grew disdainful towards).
Similar to Lotso, Gabby Gabby also has henchmen. The only difference is that Lotso's gang turned on their leader after learning of his true intentions while the Bensons do not as they just obey Gabby Gabby without complaints or questioning.
