I’m sure someone has done this before but please consider a Marichat/Adrienette Tarzan AU where Adrien grows up in the jungle, but instead of being raised by apes, he’s found by black panthers. He finds a snarky brother figure in Plagg, runs around the jungle like a panther, swift and agile and stealthy in the night. He knows he’s different from his brother, but he doesn’t know why. He has seen humans, and though he seems to have the same kind of head and arms and torso and legs as them, he doesn’t look like them, he doesn’t think he’s one of them, not really. The colors of his skin and hair are unlike the other humans hunting in the jungle, with their dark bodies painted and their sharpened spears pointed at Adrien’s animal brothers.
One day he stumbles on the crash site and finds the plane. Plagg somewhat tries to steer him away, but Adrien is drawn to the strange jagged metal. He slinks into the plane and finds a photograph–though he doesn’t really know what a photograph is, he’s innately sharp enough to work out that it’s some kind of painting. He’s elated to find that the humans on it look quite like himself, not like the other hunting humans he’s seen. One of the humans on the photo is a tall man with short silver hair and intelligent eyes, and the other is a woman long flowing hair and a gentle smile. Adrien’s heart pangs at the sight of them, though he doesn’t know why. And then there’s another human, a cub–a baby–sitting on the woman’s lap. This little human has fluffy hair, and bright eyes… It eerily looks like Adrien himself, when as a boy he used to look at the clear, still water of the watering hole before the other animals came in.
With a jolt Adrien realizes what the photograph is, and what the destroyed state of the plane means. He looks at Plagg, so many questions hammering in his chest but nothing getting past his throat. Plagg says nothing, but, in a rare show of affection, rubs the top of his head on Adrien’s shoulder.
Meanwhile, Marinette has been sent into the jungle to cook for a scientific expedition. While Mme. Mendeleiev is mostly a camper, she’s too busy doing science things to eat, much less prepare meals, thus the need for a cook. And while Mme. Mendeleiev is an intense, rather acidic personality, Marinette is given time to walk around the perimeter of the camp and sketch. One day she dares to stray a bit farther than she usually does, and chances upon a ladybug resting on a leaf. She very carefully hunkers down on her belly to inspect it before it flies away. With keen eyes, she commits the scene to memory: the exact shade of red, the number of spots, the way the light fell on the trees, and the green, green eyes in the shadows–
Marinette gasps, freezing in place. For several moments, nothing moves, not even the air nor the little ladybug resting on the leaf. And then the body that owns the green eyes inches forward. Her heart pounding against her ribs and the ground below, Marinette drinks in the sight of the figure before her. Dirtied hands, lean but strong arms, fair but slightly tanned human skin, dazzling golden hair, and the most curious green eyes Marinette has ever seen.
