The Missing Wayne (MLB X DC)

Marinette has amnesia and does remember her past from before she started living with the Dupain-Chengs in Paris. Bruce and Selina are married and are Marinette's biological parents. Marinette's real name is Marina but she could only remember the Mari part of her name. When Marinette had just turned six, she was targeted by kidnappers who were after ransom money from Bruce. The couple managed to defeat the criminals, but they couldn't find their daughter as they had sent her away as insurance that no one could harm them but the plan failed when there was a car crash of the kidnapper killing the man who took her but also causing Marinette to lose her memory and end up getting adopted by the Dupain-Chengs while they were visiting America as they had been the ones who found her in the crash. After fighting an akuma whose power makes you relive your worst memories. She gets hit and starts to remember her past slowly piece by piece. Lila manages to turn everyone but Alya, Luka, Kagame, and Adrien against her and she has to flee back to Gotham to find her real parents with the help of her adoptive parents but she still can't remember their names just where they used to live, in Gotham.

I didn't like how season 4 ended so I'm saying that all this happens before she lost the miraculous and she never loses them, cause she's already so stressed out and I don't want to deal with that, plus it doesn't fit well with the story I have planned anyways.

I don't own DC or Miraculous Ladybug just this story.
