Ranking 11 Harry Potter Fan Theories From the Highly Unlikely to the Most Plausible

It’s been over 15 years since J.K. Rowling first blessed our spirits and souls with Harry Potter and his amazing magical Wizarding World. Much of our childhoods and early adulthood were spent either awaiting the next book installment of Rowling’s epic saga, or anticipating next film release. Though we now have Harry Potter and the Cursed Child to look forward to, the biggest HP fans now spend their days combing back through the novels and films, looking for things we might have missed the first time around. Here are 11 mind-blowing Harry Potter fan theories ranked from the highly unlikely to the most plausible.

11. Dumbledore Is A Time-Traveling Ron Weasley


We realize this sounds INSANE, but just hear us out. Before Harry Potter and the Half-Blood Prince came out, this theory actually made a lot of sense. Some years back, somebody suggested that Ron was actually Dumbledore lost in time. Apparently, the two share an uncanny resemblance, an obsession with sweets, and Dumbledore knew exactly what Ron saw in the Mirror of Erised among other things. Read this super detailed essay to understand the theory more for yourself. Unfortunately (or fortunately), J.K. Rowling recently debunked this theory for good.

10. All Of This Went Down In Harry’s Imagination


In the words of Arrested Developments Lucille Bluth, “I don’t understand the question and I won’t respond to it!” Apparently there is some tragic theory hanging about that suggests Harry hallucinated the entire saga as a way to cope with living with the horrendous Dursleys abusing him as a child. NOPE! We won’t accept it!

9. Professor McGonagall is a Death Eater.


NO!! JUST NO!! While we don’t approve of this theory AT ALL, we’ll at least explain the thinking behind it. Apparently this foolish thinking all stems from the fact that McGonagall was lurking about Privet Drive the day Harry’s parents were murdered without the Order knowing about it. Furthermore, some HP fans find it strange that she was reluctant to celebrate when Voldermort first vanished, and she didn’t actually do anything in the fight against him. (If you believe this we suggest you reread the entire saga ASAP.) Read more on this absurd theory here if you want to continue to grasp at straws.

8. Draco The Werewolf


Ok so this theory is super fun and actually makes a great deal of sense. Remember in Harry Potter and the Half Blood Prince when Draco was walking around all sickly and nervous? We all just assumed that it was because he was preparing to kill Dumbledore. Well the theory is that Draco isn’t a full-on Death Eater because he doesn’t have the Dark Mark. Instead, the thinking is that Fenrir Greyback bit Draco as a child. You can read more on the theory here. However, it really is just a theory. J.K. Rowling said so herself.

7. Nagini Is Voldemort’s Wife


Apparently there is a theory going around that Moldy Voldy has a wife, and she is an Animagus who either prefers slithering about in snake form or she somehow got stuck that way. Though this is a fun theory, it’s highly unlikely. First of all, He Who Must Not Be Named doesn’t do love and affection. (If he was going to be with anyone, it would have been Bellatrix Lestrange.) And second of all, he was one of the most powerful wizards of all time, surely he could have gotten his “wife” out of snake form.

6. Lily Potter Is Hermione’s Cat Crookshanks


This is mildly plausible theory considering the fact that Crookshanks was always after Scabbers aka Wormtail when he was in rat form. There are some who believe that Lily Potter was not only an Animagus, but she also lived that fateful night. We’re not sure about this one. Admittedly, there is something more to Crookshanks than meets the eye, however he is a boy cat. Also, where was he the entire time Harry was with the Dursleys?

5. Draco Is A Good Guy


Ok, so this theory only works if you consider what happens the film version of Harry Potter and the Chamber of Secrets, but here it goes. Towards the beginning of the film Draco is hanging out in Flourish and Blotts and he rips a page out of a random book. Later when Hermione is found petrified, Harry and Ron discover a page that is ripped out of a book that explains the Basilisk. The theory is that Draco knew what his father Lucius was up to, and he slipped Hermione this information. We’re not quite sold on this one, but it could make sense…maybe. Or perhaps Draco was just being douche bag and destroying helpless books.

4. Potter Might Actually Stink


So we might actually have to pull out our vintage “Potter Stinks” buttons if we are to believe this theory. Except for his bath in Harry Potter and the Goblet of Fire, there is never any mention of The Boy Who Lived maintaining his personal hygiene throughout the entire saga. We’re sure this isn’t actually the case…hopefully.

3. Neville Longbottom is the OTHER Chosen One


Listen Linda! This is a super important theory and it makes a great deal of sense. Remember in Harry Potter and the Order of the Phoenix when Dumbledore tells Harry, “Sibyll’s prophecy could have applied to two wizard boys, both born at the end of July that year, both of whom had parents in the Order of the Phoenix, both sets of parents having narrowly escaped Voldemort three times. One, of course, was you. The other was Neville Longbottom.”  THINK ABOUT IT! Neville’s character arc in the series is BANANAS. He goes from this nerdy squib-like kid to defending Hogwarts and beheading Nagini with Godric Gryffindor’s sword. Still not convinced? Read more here.

2. Voldy The Cannibal


Knowing the Dark Lord and all of his nasty predilections, this theory seems highly plausible if you ask us. So here it goes. We all know that Voldemort had seven horcruxes, but other than murdering someone to split your soul, it’s not all that clear how a Horcrux is made. J.K Rowling has even said that she has not discussed creating horcruxes in detail, because the act is just too horrific. What’s more horrendous than cannibalism? If you’re looking for more detail on this particular theory, you can find out more here.

1. The Durselys Only Hated Harry Because He Was A Horcrux


We all love to try and find the best in Muggles, so there has to be some explanation for the Dursley’s heinous behavior towards Harry. Horcurxes make people insane! Remember when Ron had a complete meltdown while wearing Slytherin’s locket? If you had a living breathing Horcrux living with you for a decade, you’d might not be so nice and friendly either.
