Big sister's experience deciding what to wear for her little brother, but it's Mary and Billy
They've been called up for a reconnaissance mission in undercover, but everyone knows Captain Marvel SUCKS at it because he always shows up with a huge trench coat, sunglasses, a mysterious hat and his bright red suit would still be pocking up somewhere
But they really need Marvel to do it, and he's like "don't worry! This time I can really pull it off, okay? I promise"
But Mary is there, Mary listens and she smiles like a little devil
"The problem is that Cap is terrible at dressing up, he's such a workaholic that he doesn't even know how to dress without the hero vibes anymore. But that's okay! Mister Batman, can we have some money? I promise I'll make Cap look unrecognizable for this mission! There's just nothing really suitable in his wardrobe."
And Batman just says, "Okay, I'll send you enough money. Please, Miss Marvel, don't let him come in his suit again…"
And then they plan to have Marvel show up at the watchtower before the mission, because they need to make sure he's actually dressed for it. And well, it ends up with Guy Gardner setting off the alarms because of an intruder, but when they go see him, it's Marvel who's looking like the most dad-like guy ever.
flannel shirt, high shorts, tacky belt, a FAN PACK!!! and sneakers
But like, he looks so normal. Seriously. His hair is different, he even has some makeup on to fake frown lines and dark circles on his face. He looks very human, very civil, and he's so dad-coded. Captain Marvel is already dad-coded, but like, a super dad. This dad in front of them is just a tired and proud father with tired eyes but a smile that shows how happy he is in this role.
Mary comes next, she is also dressed as a teenager, and she is smiling so brightly that the stars are jealous.
She is very proud and thanks them so much for letting her do this. She always wanted to pick out Cap's clothes because he is terrible at it and she loved playing dress up with him for a while.
The undecover goes well, it's in a mall and no one even blinks at the dad!cap and daughter, both super casual and happy and normal
Later, Batman finds a video from a security camera, and it's 4 in the morning in a clothing store, Mary and Marvel are there and it really looks like they're playing dress up. Mary picks out things for him, he tries them on and goes to show them to her, he makes some jokes, parades, laughs a lot and everything
Bruce finds this father and daughter moment (because they really don't know they're brother and sister) really cute and it inspires him to ask his daughters to go shopping with him soon
Well, he deletes the videos for the heroes' safety, but he has a backup because he wants to show it to other league mates too. Plus, information.
And Mary is so happy, she wishes she could dress Billy too, not just Marvel. Because, my God, Billy Batson, YOU'RE NOT GOING TO SCHOOL WITH ME IN THOSE SONIC SHOES, SONIC T-SHIRT, BATMAN SHORTS AND WONDER WOMAN JACKET, GET OUT OF HERE
