Supernatural/Harry Potter Crossover – Family   Leave a comment

Challenge Pairing: Harry/? Whoever, so long as it’s SLASH and fits into the storyline. MPREG is good and welcomed…

Objective: What if John Winchester had a brief affair with an English woman, named Lily Evans, soon to be Potter. Lily gets pregnant with John’s child, and still goes through with marrying James, whom she cheated on. James is aware that the baby is not his, but because he loves Lily, decides to forgive her and accept her son as his own. He still names Harry his heir.

Lily tells John that she is pregnant, but knows that John already has two sons, Dean who is just turning 13, and Sam, who is barely 9. Lily knows that John is a supernatural hunter, and John knows that Lily is a witch – one that is born with magic. John agrees that should anything ever happen to either her or James, then he was to get custody of his third and youngest son. Lily would update him, through owl post and long distance calls, about Harry, yadda yadda yadda.

When Voldemort attacks and kills Lily and James, John leaves Sam and Dean in the care of Bobby Singer and heads to England to check up on Harry. He and Lily had discussed the war and the prophecy hanging over their son’s head, and so he knew that there was a high possibility that Lily would not make it, so the two, as well as James (who of course, hated John but for Harry’s sake dealt with the situation maturely) discussed what was to happen should the time come.

Lily had given John the address and phone number of her sister Petunia, in case Harry was ever placed in her care. There was no telling, with Dumbledore, after all.

John arrived at the Dursleys and decided after lots of thinking, to leave Harry with them. He didn’t know about the abuse that would soon fall upon his youngest child. While John left Harry in the care of the Dursleys, he made sure that Harry knew that John was still around.

Between ages 2 to 11, John called the Dursleys to speak with his son, to make sure Harry was doing all right. He called on Harry’s birthdays, the holidays and in between them all. Because of John’s hunting, it often took a while but he would call. Just because he was a hard-ass and stubborn, John did love all three of his children equally, cherished them even. John felt bad that he had raised Dean and Sam the way he did, and was thankful that Harry was far away from the hard life of hunting the supernatural. However, he forgot that the wizarding world was just has harsh and he had no idea that the Dursleys were anything but safe for Harry. He had wanted Harry to have childhood, unlike Dean and Sam’s, but Harry actually had a childhood worse than them.

From the time Harry could walk, Vernon would physically abuse him. He was starved, beaten, neglected, ignored and forgotten.

Harry is a Magical Hermaphrodite. He had always known at he was different. Harry has had his MH since he was born, but Lily covered it up using her skills with Charms, casting a powerful glamour over him. It wore off eventually, so Harry had to use his wandless magic to reapply it. John knows this about Harry, as Lily told him this just after she had discovered it herself. She, James and John were the only ones who knew about his MH. Now, Harry too, of course.

Harry is able to perform some wandless magic. He uses wandless glamours to hide his Magical Hermaphroditism, and his femininity. Harry has always had a very strong control over his magic – his magic often acted with just a thought from him, and once he discovered he could do things with barely a thought, he began practicing his control. Over time, he was able to do wandless and will magic effortlessly. Glamours, Levitation spells and light spells were the easiest for him to cast wandlessly.

Harry has a photographic memory. He uses this to soak up the muggle school subjects and later, the knowledge of the magical world. Harry’s mind is a lot more organized than most, and because of this, it performs at extraordinarily fast levels. He can speed read, remember past events with crystal clarity and bring up whatever his mind seeks to know – if it stored somewhere within. His mind works a lot like a library. All of what he knows is storied into sections, and he as to reach out into his mind and grasp what he needs. (I can’t really explain it, but hopefully you get what I’m trying to say).

When Harry entered Hogwarts, he is instantly aware that he does not belong within the wizarding world. He hates it there, with is fame and the tale of Voldemort. He makes friends with Ron and Hermione, but it’s only a half-hearted effort. To them, he seems genuine, but really, it’s only a façade. Secretly, Harry is studying his butt off at night and in between the little time he has to himself, so that he can get all the knowledge he needed for his magical education and then leave as soon as possible. He was not planning on being at Hogwarts or in the wizarding world any longer than he had to.

With his photographic memory and his wandless/will magic, he was able to move quickly through the Hogwarts material. By the end of his first year, he knew all the material up to third year. By the end of second-year, he knew all the material up to half-way through fourth. By the end of his third year, he was sixth-year level in knowledge. By the time Harry finishes his fourth year at Hogwarts, he was completely finished with the Hogwarts material and had even a little bit of knowledge into Auror-level spells, potions, etc.

Harry returned to the Dursleys at the end of 4th year, depressed over the death of Cedric Diggory. He had managed to prevent Voldemort’s rebirth, however, thanks to his wandless magic – he was able to use his magic to break the spell holding him to the tombstone, then stun the magic-retarded Pettigrew and then kill the rather pathetic and weak Voldemort, who couldn’t even cast a spell. Two days into his stay at the Dursleys, Vernon starts in on his beatings and starvation again.

Fed up with the Dursleys, Harry leaves. He sneaks away, and goes to Gringotts by way of Knight’s Bus. The goblins hire several of the Ministry officials, who are then bound by a wizard’s oath, and Harry is able to take his OWLs and NEWTs prematurely. He passes with flying colors. **He stays at Gringotts for at least two weeks to take every single test**

Once his tests results come in, the Ministry officials and the goblins come to a unanimous agreement, to have Harry emancipated. This allows Harry to use his wand, where he can’t use his wandless magic.

When everything is settled and ready for him to leave the wizarding world behind, Harry decides that he wants to find his father in America. The problem is that he hasn’t talked to his father before since his second year. The goblins agree to track them down magically. Unable to find John Winchester, the goblins do find a Sam Winchester.

Given the address where his previously unknown older brother (John had not mentioned Sam or Dean to Harry, just as Harry was never mentioned to Sam and Dean) was staying – a motel in Pontiac, Illinois, USA – Harry is given a goblin-made portkey that takes him straight to that address.


This challenge takes place at the very end of Season Three and beginning of Season Four. Dean is in hell, but has just gotten out as Harry arrives at Sam’s motel, who is with Ruby at the time.

Harry — on the brink of 15-years-old

Dean — around 28-years-old (he is 13 years older than Harry)

Sam — 24-years-old (he is 9 years older than Harry).

I want Dean to become the father/older brother figure to Harry, making him ten times more protective of him than he is with Sam. Sam kind of channels Dean’s protectiveness of him when it comes to Harry. Both men are super protective of Harry, who, with his MH, is often in the form of a petite female. Harry’s Magical Hermaphroditism makes Harry their baby brother-sister. He loves his female form more than his male form, and therefore is usually in his female form, but he also spends time in his male form (which is still very feminine and tiny).


—    5’0’’ at the least, and 5’4’’ at the most.

—    Mid-back length jet-black hair.

—    Deep emerald green eyes.

—    Petite, feminine stature, in both male/female form.


—    6’2’’

—    Short brown hair with natural light/blond highlights.

—    Olive green eyes.

—    Muscular build – abs, biceps, broad shoulders, etc.


—    6’5”

—    Shaggy brown hair

—    Hazel brown eyes (more brown than green)

—    Muscular build – abs, biceps, broad shoulders, etc.

0o0 Harry’s name cannot change, especially in his female form. He is to be known as ‘Harry’, though you can have his real name be something like Harrison or Harrietta. So long as his nickname or shortened name is Harry, then everything is good.

0o0 Harry wears women’s clothing, even in his male form. He doesn’t like men’s clothes because it is too baggy – it remindes him of the Dursleys and Dudley’s cast-offs. Women’s clothing is tighter and more form fitting, and he prefers them over men’s. With his feminine body and his long hair (even in his male form), he is easily mistaken as a girl, just a very petite one. Don’t forget that he IS a MH (see Definition Page for the Magical Hermaphrodite definition).



Just an overview of my outline for this idea. Another challenge, waiting for someone – anyone – to write. You’re welcome to it, if you want it.


An example to where I’m going with this story can be found here. Brother, My Brother This is the first/beginning chapter. Whoever adopts this story may or may not use this start-up chapter. I may or may not add more to the FF.Net account, so for now read this as if this is all you have to go on.
