Fox Miraculous is a necklace that, whenever Trixx inhabits it, transforms the wearer into a fox-themed superhero. Master Fu seems to be keeping it for now, as seen in " Ladybug & Cat Noir", and its abilities are unknown. At New York Comic Con 2017 the holder of the Fox Miraculous was revealed.
The Fox Miraculous appears to be a necklace with a small golden chain with a white-tipped orange fox tail charm attached to it.
The Fox Miraculous' special weapon is a
reed flute, as illustrated in the Miraculous book.
List of owners
The Great Guardian. He is currently storing the Fox Miraculous in his chest.
Foxes are a symbol of cunning, wisdom, and passion.
In the theme song, the Fox Miraculous briefly appears in Master Fu's chest, although it is obscured by the raised middle section of the chest box with the Ladybug Miraculous and Cat Miraculous.
In " Volpina", Lila purchases a necklace with a similar design to support her lie to Adrien that she is a Miraculous holder, and it becomes her akumatized object.
In the Miraculous book, one of the codes on the Fox Miraculous page translates to Volpina, but it's unknown if it's the name of the Fox Miraculous holder depicted or a reference.
When Lila is akumatized, becoming a copy of Volpina, she gains the power of illusion, but it's unknown if this is the real Fox Miraculous' power.
At the Anime Expo 2016 panel for the show, it was stated that the wielder of the Fox Miraculous (not an akumatized villian based off of them) "will be potentially a recurring character."
This was confirmed again at the panel at San Diego Comic Con 2016, along with that the Fox Miraculous and its wielder will appear in Season 2.
 At the New York Comic Con 2017, the Fox Miraculous holder was revealed.
