I’ve been having a lot of #Emotions about trans Ladybug and Chat Noir lately so take some head canons.
Miraculous transformations take the wielder’s wants into consideration, and change to best reflect the ideal vision that person has of themselves.
Marinette’s Ladybug suit is equipped with clever bits of padding in the chest and hips, giving her a more shapely appearance. It also comes with a magical self-tucking mechanism that she tries not to think too hard about but definitely appreciates once that skintight suit conforms to every inch of her body. Additionally, her hair is glossier, her eyelashes are longer, and her voice sounds just a bit higher than usual when she’s transformed.
Like Ladybug, Adrien’s Chat Noir suit is also padded, only his is in the shoulders and (later on, after seriously bribing Plagg) a bit below the belt. Beyond that he’s got hidden wedges in his boots to give him a height boost and a god-tier binder. His hair and voice also undergo a slight change, becoming shaggier and deeper respectively.
I think for about the first year of their partnership Ladybug and Chat Noir aren’t out as trans to each other- either because they are nervous about how the other might react or because for the first time in their lives they are in a position where they don’t have to be out. They can just do their thing and save the day without an extra label floating over their heads.
Of course after they spend more time together, growing closer as partners and friends, they start to pick up little hints that maybe just maybe they arent alone in this whole trans superhero thing. Those clues pile up until one day Chat accidentally lets slip one of his many trans-related puns, effectively letting the cat out of the bag. Panicked, he tries to play it off as nothing, but Ladybug has already put two and two together and is already BEAMING.“Thank goodness,” she laughs, clapping Chat on the shoulder. “For a minute there I thought I was the only one!”
Ladybug then proceeds to gush about how great their suits are and how glad she is to hear they’ve got one more thing in common and Chat is just hit over the head with this massive wave of relief, because he has never ever had someone react so well to his coming out and he can literally feel himself fall more in love with his Lady by the minute.
Cue them both being supportive af, helping each other through the unique challenges they have to face. Chat is there to lift Ladybug’s spirits when her HRT causes mood drops; Ladybug makes sure Chat doesn’t overexert himself in the weeks after his top surgery; They both joke and laugh and bond over their shared identity in a way that they just cant with their cis friends and everything is good and happy.
Eventually the reveal happens, and eventually Adrien and Marinette start dating, and eventually Ladybug and Chat Noir publicly come out as trans, becoming role models for non-cis kids all over the world. Then they grow up, get married, and adopt 3 cats 7 hamsters and 4 children and live happily ever after the end <3
