Vote up the theories that are just so magical they might be onto something.

There’s nothing like a batch of Harry Potter fan theories straight out of the piping hot cauldron of the internet to make the day seem brighter. The Potter books and films are seemingly made for fan theories, with new ones popping up daily. Rowling’s (or should we call her Rita?) vibrant world is dissected all the time despite the fact that the first book, Harry Potter and the Sorcerer’s Stone, was published in 1997. Even Rowling enjoys Harry Potter universe theories. She particularly likes the one about Dumbledore being Death in the Deathly Hallows story of the Peverell brothers. She said, “It fits.”

But does the fan theory that Ginny slipped Harry a magical love roofie fit? Because for the longest time, it seemed like she was the only one carrying a torch, and Harry couldn’t have cared less. How about this one: Dumbledore is actually Ron? And George Weasley is Willy Wonka? Yep, there are some pretty wild, yet fun, Harry Potter theories out there.

There are quite a few strongly-held Harry Potter fan theories that make sense. Like how Draco Malfoy is a werewolf. He’s got that tortured thing going on. Is this the Dark Lord’s doing? Did Voldy have Fenrir take a chunk out of Malfoy because he failed to deliver the prophecy, and this was something that happened to Death Eater’s children when they messed up?

And with the addition of the upcoming Fantastic Beasts series, new theories have popped up. Is Credence Barebone Voldemort's dad? Is Percival Graves actually Gellert Grindelwald? Did Newt Scamander give Hagrid Aragog? So many theories sprouting up and will only grow as the five-film series rolls on. 

Which Harry Potter fan theory makes the most sense? Point your wand at the ones you think are most likely to be true and levitate them up to the top (with your votes, that is).

    Neville Longbottom Uses The Wrong Wand

    Neville Longbottom Uses The Wrong Wand
    • Photo:

    Because he chose his father's wand, Neville didn’t let the wand choose him. This explains the constant misfires, but it worked well enough because it was his dad’s. When Neville’s wand is broken at the Battle of the Department of Mysteries, he gets a new one at Ollivander’s. This time, the wand chose him and helped him become the leader of Dumbledore’s Army in his seventh year.

    Did Hagrid Get Aragog From Newt Scamander?

    Did Hagrid Get Aragog From Newt Scamander?

    MuggleNet may have unearthed something pretty cool with this one. Aragog, the Acromantula, explains how he came to be with Hagrid in Harry Potter and the Chamber of Secrets: "I came to Hagrid from a distant land, in the pockets of a traveler." 

    Scamander ended up at Hogwarts after his travels across five continents to study, collect, and protect fantastic beasts. So it’s altogether possible that a younger Hagrid met a middle-aged Scamander at Hogwarts in the ‘40s.

    There's another connection (besides caring for misunderstood beasts of the world) between the two. Hagrid and Scamander were both expelled from Hogwarts, only to return as professors later.

    Trelawney Was Right About Harry’s Birth Date

    Trelawney Was Right About Harry’s Birth Date

    Even though Harry was born in July, Trelawney tells Harry he was born in midwinter.

    That’s because a part of Voldemort’s soul was inside Harry, and Tom Riddle was born on December 31, smack in the middle of the winter season.

    Crookshanks Used To Belong To Lily Potter

    Crookshanks Used To Belong To Lily Potter

    This one comes from Yedu Krishnan who says that when Hermione buys the cat at Magical Menagerie, the owner says they’ve had the cat for “quite some time.” Harry often wondered if their cat survived the attack by Voldemort when he was a baby.

    So when Crookshanks recognizes Scabbers/Wormtail and Sirius in their animagus forms, it’s a strong clue that Crookshanks was Harry’s family cat.

    The Dursleys Strengthened Harry By Being Awful

    Is Harry who he is because of the harsh treatment he received from the Dursleys?

    Tumblr user Great Hero Battle Fight suggests the following theory:

    Almost every single character trait exhibited by Harry can be linked back to his time at the Dursleys: He’s a good seeker because he was malnourished enough to be small and fast, and had gained excellent reflexes from constantly dodging their swings at him. He wants to protect and help others, because no-one helped him. He hates bullies, like Malfoy, because he was bullied. He doesn’t try at school, because he was never encouraged at home, and in fact, was probably punished if he did better than Dudley.

    Even Harry’s lack of curiosity about his family, his past, leading to Hermione or Ron to explain everything is linked back to the number one rule at the Dursleys’, ‘Don’t ask questions.’

    Voldemort, Harry, And Snape Are The Three Brothers And Dumbledore Is Death

    This fan theory states that the three characters are the three brothers from the "Tale of Three Brothers" story in Deathly Hallows and that Dumbledore is Death. The story goes that the brothers meet Death on the road. Death offers them their deepest desires in exchange for their souls. The first wishes for a powerful weapon and is given the Elder Wand. The second asks Death to bring back his wife and receives the Resurrection Stone. The third brother cleverly asks for a way to hide from Death and is given the Cloak of Invisibility. Voldemort dies for power, Severus dies for love, and Harry speaks to his old friend, Dumbledore/Death, in the afterlife. 
     
    Rowling loves the Dumbledore theory, tweeting, “Dumbledore as death. It's a beautiful theory and it fits.” 
     
    Further, Dumbledore represents all three brothers. When he was young, he sought power. He lost his sister and might have longed to see her again. And he wasn’t afraid to die, greeting it “like an old friend.”
