So I just heard about @nobodyfamousposts fics about if Marinette accidentally brought a doll to life with the power of creation. So I am gonna put some head canons)
-Marinette was initially horrified about what she had done, considering she just brought an inanimate object to life. But she slowly warms up to it.
-Little chat doesn’t need to eat, since he is simply a doll and has no need for food or air.
-Chat noir does get to meet the little guy eventually, he finds it adorable that Ladybug made a mini him. Joking if that makes him the papa. “He looks just like me”
-Marinette ends up finding him constantly trying to sneak into her bag to go to school with her. Which she tells him no. He still does it.
-One day Little chat does something to ruin one of Marinette’s projects, and Marinette yells at him. Making him feel horrible.
-Marinette realizes what she had done and quickly tries to apologize.
-Since it is alive it has emotions, and therefore can be akumatized. (Since Robustus proves that if it has feelings it can be akumatized)
-Little chat gets bummed out a while after, always being forced to stay at home to avoid trouble. It feels like Marinette doesn’t even care about him. it makes him sad.
-In the episode he gets akumatized, he needs to be destroyed in order to free him of the akuma.
-Ladybug being mega reluctant to do it. She doesn’t want to hurt him
-But she does it, and immediately casts Miraculous healing.
-Miraculous healing reverts Little chat back to his original state, as a lifeless toy.
-It breaks Ladybug’s heart.
-Chat noir comforting her telling her it isn’t her fault. That this wouldn’t have happened if Hawkmoth wasn’t involved.
-This makes Ladybug hella determined to BRING HAWKMOTH DOWN!
-Hawkmoth realizing he had done f***ed up
