Here it is, the last for the mini-collection: Pantera, from "Top Cat Begins"
To me, she is Fancy´s first ex-girlfriend (I know that the movie is the prequel of the series)
On my headcannon, they are dating in secret, after the happenings of the prequel, series and movie, because after escaping from his girlfriend from the movie, meets Pantera, in a bar and reverts to his shy persona from the prequel, but it doesn´t last long, when she looks at him and smiles, saying that she actually liked him from the start and their breakup wasn´t planned. And explains that she and her boyfriend broke up, after he discovered her criminal past, and that Fancy was the only one that she liked in her life. And after that meeting, they start to meet in secret, in order to the gang don´t freak out, about one of the members dating one of the villains henchman.
