Man, the Unicorn Miraculous is such a fascinating topic! In the 'Miraculous: Tales of Ladybug & Cat Noir' universe, it's wielded by Chloé Bourgeois during the 'Miraculous World' special. Honestly, it was a wild character arc—she starts off as this bratty antagonist, but seeing her step up with the Unicorn Miraculous was kinda satisfying. The design is gorgeous too, all pastel and sparkly, totally fitting her dramatic personality.
What’s cool is how the Unicorn Miraculous represents 'illumination,' which is ironic because Chloé’s journey is all about self-discovery. She’s not perfect by any means, but that’s what makes her compelling. Also, the way she uses the power to create light-based illusions is just chef’s kiss. It’s a shame we didn’t see more of it—I’d love a spin-off exploring her as a proper hero.
