Trixx is one of the tetartagonists of Miraculous: Tales of Ladybug and Cat Noir, and the kwami that is connected to the Fox Miraculous. Throughout the show's second season, he occasionally helps Alya Césaire transform into the superhero Rena Rouge to assist Ladybug and Cat Noir during certain missions.
He is voiced by William Coryn in the French Version and Cherami Leigh in the English Version.
Trixx is a small fox-like creature with purple eyes, eyelashes on the side of either eye, two dark brown spots on her forehead that look like eyebrows, and fox ears that are white on the inside and have black tips and edges. She is predominantly orange, but the area around her mouth, the tip of her tail, and her chest are white, while her arms and feet are black.
Trixx is shown as being friendly, wise, encouraging and a good judge of character, being able to identity the most positive qualities of her new wielder, Alya. She makes no effort to hide it if she is impressed by something, as shown by her reaction when Alya figured out that her purpose is to help her transform. She is also a good advice-giver, like when he convinced Alya to give her Miraculous back to Ladybug like she promised by reminding her that she is a honest person.
Like all kwamis, Trixx can fly, levitate, phase through solid objects, and carry things that are bigger than him.
Trixx can transform the holder of his Miraculous into a fox-themed superhero by going inside their Miraculous and allows them to use Mirage, a superpower which allows them to create an illusion. However, after has been used once, Trixx will lose his energy and leave the the Miraculous after five minutes, at which point the holder will revert back to their normal self. To transform again, the holder must recharge Trixx by feeding him.
Thousands of years prior to the series, Trixx and the other Kwamis traveled the universe, unable to interact with any creatures, particularly humans. This was until a mage forged the Miraculouses, so Trixx and the others could both interact with mankind and grant them the ability to transform into heroes; Trixx and the Fox Miraculous able to give a person the ability to grant other people superpowers.
Trixx first appears in the episode "Sapotis" when Ladybug temporarily gives the Fox Miraculous to Alya. Trixx is impressed when Alya realizes that his purpose is to help her transform into a superhero, and Alya uses him to transform into Rena Rouge. After helping Ladybug and Cat Noir return her akumatized little sisters to normal, Trixx, seeing that Alya is hesitant to return his Miraculous to Ladybug like she promised, agrees that they would be a great team, reminds her of her positive qualities, particularly her honesty, and this convinces her to honor her promise and give Trixx's Miraculous back to Ladybug, who then takes it back to Master Fu.
