* EnsembleDarkhorse:
** Carmen, Patty's mother for how sweet and [[DotingParent doting]] she is towards her daughter.
** Josefina, Patty's best friend, for her sweet personality.
* HilariousInHindsight: She said proudly "Antonella es única" (Antonella is unique). [[Series/LosUnicos Indeed]].
* MisaimedFandom: The writers of the show wanted to show that beauty doesn't always equal goodness. However, the audience preferred the mean, but pretty [[AlphaBitch Antonella]] from the sweet and well-intentioned, but ugly, Patty.
* OvershadowedByControversy: Thelma Fardín (Josefina) denounced in December 2018 that Juan Darthés (Leandro) sexually abused her back in the day, during a promotional trip for the show in Nicaragua; Darthés denies it. This led to a judicial case in Nicaragua (as the crime is alleged to have taken place there, and not in Argentina) and a huge controversy in the media, including most Argentine actresses starting a campaign compared with the 2017 [=#MeToo=] campaign. Needless to say, hardly anyone who mentions ''Patito Feo'' nowadays will be making reference to anything about the show but that.
* RootingForTheEmpire: Infamously, and noted on the other wiki, children preferred the pretty, yet evil, Las Divinas to Las Populares. Partially ties into MisaimedFandom, as the point was to subvert BeautyEqualsGoodness.
* SignatureSong:
** "Gasolina" from Las Divinas was (and still is) the most popular song.
** "Fiesta" as well, for how catchy it is.
* TheyWastedAPerfectlyGoodPlot: The whole change of bodies would have allowed an interesting sight, to see Brenda Asnicar (Antonella) singing "A Volar" or some other song of the Populares, and Laura Esquivel (Patito) singing "Diosa Unica Bonita" or some other song of the Divinas. But it was never done.
* VocalMinority: As irritating might be her fans, Antonella is not loved by everyone. Back when the show was on, she was all everyone talked about, resulting to some people bushing her for ItsPopularNowItSucks reasons.
