Random Fanfiction Idea: Harry Potter & Danny Phantom

It's just past midnight, a 9-year-old Harry Potter, abused by Uncle Vernon, accidentally apparates to the northern middle of the USA, in Amity Park, Minnesota. Upon arrival, Danny's parents, Maddie and Jack Fenton hear an alarm going off from one of the various gadgets they keep in their pockets. It's 6:30pm CST. They rush from the dinner table, telling 15-year-old Jazz to watch 13-year-old Danny for a bit, get in the car and put on the sensors. It picks up a faint dot on the radar, they zoom towards it, stopping before some thick woods. Following the beeping device, they find Harry, huddled in on himself and asleep. When Jack reaches to touch him, Harry's magic flares. The beeping goes wild and then dies down again. Both adults knocked on their butts. Maddie goes to Harry and is surprised to find no back-lash this time. She and Jack bring home this strange boy, not knowing what he is, but curious to find out and help him recover.

Story goes on with Harry adopted by the Fentons and Danny growing up with him for 2 years, (at 14, Danny gets transformed alongside Harry, only tells Sam, and Tucker) then two letters arrive in the post one day for Harry, both asking him to go to a magical school. One to a far away school called Hogwarts, the other only an hour drive away called the Tolbek House of Magic. Despite the further one stating things like relatives having gone there, Harry's only experience with 'relatives' hasn't gone well, so he writes back declining it. Maddie and Jack are beside themselves in curiosity and excitement, insisting they go in person to this Tolbek school and explore it first-hand.

In Hogwarts side; Dumbledore upset, Voldemort comes back during first year, goes on rampage looking for Potter, no trace in the entire UK, leaves the UK in search following a potion using a hair, the death eaters without need to stay join him. Brings him to Minnesota and then potion wears off. No more ingredients.

Harry's made friends and learned a lot, Danny would fly over and visit often. They would discuss the various ghost adventures Danny had, sometimes train abilities together or help each other with a problem going on.

Jazz is going off to college, a few states away, far away from her crazy parents and crazy town. Voldemort finds some clues as to Harry's where-abouts, heads to Amity Park. During this summer break, Harry practices wandless magic, a more commonly used magic in the USA and continues joining Danny on random adventures.

Voldemort finally finds Harry, determined to stop the prophesy from coming true, he attacks in the night, Jack and Maddie nearly die, saved by their sons' powers. Jazz is already at her college in the dorms. This is where they learn their sons are half human, half ghost. Voldemort freaks out, the death eaters are all captured and unconsious, Voldemort is sent to the ghost-zone. Harry turns the death eaters over to the local magical authorities, who port-key them back to the UK ministry for trial and incarceration at Azkaban.

End? -Voldemort could come back as a vengeful ghost, being that he's still connected to the world by his soul fragments.
