Need to know if this fic idea already exists. If it doesn't, SOMEONE PLEASE WRITE THIS.
Ok, so I just read "Harry Potter and the Asterous Wandmaker" by Aprotny on AO3, and it gave me ideas.
The basic premise is that Mary Grayson was a friend of Lily Potter who agreed to look after Richard for a few days while Harry was sick, as Richard was a newborn and they didn't want to risk him getting ill as well, but then they die and the Greysons end up adopting Richard for real and raising him until Canon DC events occur. Shenanigans ensue that lead to Harry moving in with Bruce at 15 and Voldie is killed early.
My thought was, what if it was this, but with Maddie. So Maddy takes on Daniel, and a miscommunication occurs that leads to her believing Harry died with his parents. Due to her being a squib, she only tangentially knows about the wizarding world, and this is what fuels her desire to study ectobiology. She KNOWS they're real. She just has to prove it.
The only other person who knew about Danny was Peter, and due to some small sliver of loyalty, he never told anyone about him. Harry finds out in the Forbidden Forest when he's walking to his death as his parents tell him they can watch over Danny's life together or something, and sets off to America once he'd recovered after the battle.
Harry could be Master of Death and help Danny out with his ghost battles
Harry could set off all the ecto-alarms in the house, causing the boys to gaslight the Drs. Fenton into thinking that it's going off due to them being British born or due to magic
Danny could be a squib, which is what helped him survive the accident
Harry could arrive pre portal/ just after it happened
If Harry is 18, he might fight for custody of Danny, due to the house being unsafe for him to live there
Opportunity for billionaire vs billionaire showdown when Harry finds out what Vlad is doing to Danny
Danny could tell everyone Dani is a Potter and get her an official identity through the goblins, this could be how Harry finds out about Plasmius being Masters
For a bonus, if you want to add in the DC universe, John Constantine could be a squib relation thriving the Black family, or a relation through the Evans family. The older brother that Petunia pretended she didn't have
I just really don't have time to write this but it won't leave my head.
