For the election of the official mascot of the games, an online vote was held from August 5 to 25, 2021 among the 5 options presented: «Fiu», a seven-colored tyrant; «Pewü», an araucaria pine nut; «Chitama», an Atacama running lizard; «Juanchi», a Humboldt penguin; and «Santi», a winged puma.

[21] In the days after the opening of the Pan American Games, counterfeit versions of the Fiu plush emerged,[22] as well as the figure of the mascot was used by the Santiago Metro to deliver safety tips.

[23] In the town of Pomaire, belonging to the Melipilla Province, famous for its clay crafts, a version of the traditional pig painted with the colors of the mascot of Santiago 2023 was created, being baptized as "Chanchifiu".

[7] In recognition of his prominence during the development of the event, the president of Panam Sports, Neven Ilic, awarded the last gold medal of the Pan American Games to Fiu during the closing ceremony on November 5.

[24] A day later, the executive director of Santiago 2023, Harold Mayne-Nicholls, announced that Fiu will carry out a national tour in order to visit schools or other institutions that require its presence.
