Nothing is perfect in our lives, neither is the super work in the literature and the cinema world – Harry Potter series. Today we reveal you 15 biggest Harry Potter plot holes in Harry Potter books. Keep reading to find out what they are!

15 Biggest Harry Potter Plot Holes

1. Voldemort’s skill for timing

Lord Voldermort’s timing is weirdly predictable as he always attacked when the school year finished. He assaulted Harry frontally at the end of the first year to the fifth year, and the seventh year, except for the sixth year. We guess that Voldermort concerned more than the disruption for the Hogwarts students. So, why wouldn’t the Dark Lord make more attempt on the stone throughout the school year?

2. Harry & the Thestrals

Only people who witness the death can see a Threstral.

Thestrals which are horse-like and winged beasts were seen only by those who had seen death before. Harry first saw them at the beginning of his 4th year, after the Cedric Diggory was murdered.

Theoretically, he should be able to see these Thestrals then. However, they remain invisible till the next chapter. Another unexplained detail is Harry has already witnessed his parent’s death at the early stage of the series, but this couldn’t make those Thestrals visible.

3. Peter Pettigrew vs. the Maurader’s map

For many years, Peter Pettigrew had been disguised as Ron’s pet rat. Ron had called it Scabbers, slept with it every night and taken it around many times. No matter which Animagus form Peter is, he would be indicated on the Map of the Maurader which has the ability to reveal everyone’s location at Hogwarts.

Fred and George (Ron’s twin brothers) had owned this map for years and sometimes used it to plan some pranks. But none of them had noticed that there was a man named Peter Pettigrew sharing their brother’s bed every night. That’s weird, right!

4. Food scarcity in the 7th books

At the time Harry, Ron, and Hermione were on the run in “Harry Potter and the Deathly Hallows” – the final books, they struggled to find food. Though these guys are all magicians, hunger still a tough problem for them.

Well, it’s impossible to create food by using magic according to the five exceptions of Gamp’s Law of Transfiguration (repeatedly stated in the books). But at least they could transform, increase or summoning it, couldn’t they?

It’s also interesting to note that Hermione once explained to Ron and Harry: “It’s impossible to make good food out of nothing! You can summon it if you know where it is, you can transform it, you can increase the quantity if you’ve already got some.” And you know what Ron said: “Well, don’t bother increasing this, it’s disgusting.” Well, he denied increasing the food just because “it’s disgusting” while all of them are too hungry. Doesn’t sound convincing, right!

5. How Azkaban escapees get their wands back?

When bad witches and wizards are imprisoned in Azkaban, their wands are taken away so that they can’t fight against the prison guardians. Throughout the books, we know that there are no two wands having the same look, and it’s rare for anyone in the magician world to have more than one wand in their entire lifetime.

But the books have never explained where Sirius Black and Bellatrix Lestrange eventually get their wands back after escaping Azkaban. Maybe they stole their wands afterward, or Ollivander secretly made a new one for each of them, but none of these theories are explained in the books.


6. Who was the master of the Elder Wand?

Draco Malfoy achieved the loyalty of the Elder Wand as Dumbledore was gripping it when he disarmed Draco. Therefore, Draco took this wand from his teacher. Yet in some ways, Harry changed a completely different wand to the Elder one and soon became the controller of a wand that he never took.

7. ‘’Missing day’’ plot hole

In Harry Potter and the Philosopher’s Stone, Harry fans have realized a major flaw, called it by the “Missing Day” name. It started when Voldemort had known the whereabouts of Harry’s parents – James and Lily through Wormtail, then killed them in their home on 31st October.

Harry, fortunately, had been brought out of the ruined house by Hagrid. Hagrid insisted that it’d been an easy journey, especially with the support of Sirius’s magical motorcycle. The question here is “why did they spend 24 hours on getting there?”

8. Why did Harry forget the two-way mirror?

At the beginning of Harry Potter and the Order of the Phoenix, Sirius gave Harry a two-way mirror that he and Harry’s dad used to contact each other when they were in school. This mirror, no later, brought into play after Harry successfully used it to contact Aberforth.

Throughout the book, Sirius kept getting in touch with Harry through floo powder. And they did that many times in spite of knowing that this manner wasn’t safe for Sirius (because the fire was being tracked by the Ministry of Magic). In the end, Harry tried and failed to reach out to Sirius through the fire, leading to the death of his uncle.

The question here is how did Harry not try at the two-way mirror after the first option had failed?

9. How could Lupin forget about the full moon?

In the Harry Potter and the Prisoner of Azkaban, Harry, Sirius Black, and Remus Lupin took Peter Pettigrew to Hogwarts to explain everyone the truth about who betrayed Harry’s parent. We all know Lupin will transform into a werewolf and Pettigrew will transform into a rat when the full-moon night comes out. However, it seems that Lupin and Harry forgot about that, and this destroyed their whole plan.

The thing that lacks persuasiveness is how could Lupin forgot about the merciless vow that happens once every month for most of his life. If he remembered this, he could just wait inside the Shrieking Shack until the sun rises and also detain Pettigrew to make sure there is no way for him to escape.

10. The wizard economy makes no sense

Money is one of the five exceptions of Gamp’s Law of Transfiguration, which means no one can use transfiguration to make money or even increase its quality, like food. So you can see that in the world of magic, the concept of money (stock and currency exchange) stills exist, but the way people exchange it is really questionable.

The best example is the price of wands sold by Ollivander. Each wand costs only 7 galleons while the unicorn hair (a common ingredient added to the wand) costs up to 10 galleons. So, Ollivander would take a loss of 3 galleons on almost every single sale. Some wands even have more expensive ingredients like phoenix feathers or dragon heartstring, which means he would lose even more! Perhaps there are some exceptions on special circumstances? I don’t know!

11. Was only the Slytherin bad?

The wizards from Slytherin are always on the bad side?

The Slytherin is supposed to be an “evil” house, including several famed witches and wizards who became the worst of the worst. One of the most typical examples of this is Voldemort, not mentioned that his followers as well as the Malfoy family.

Harry was even told that there wasn’t any a witch who had gone bad that hadn’t been in Slytherin. Later, a Gryffindor witch – Sirius was sent to Azkaban for murdering 12 witches and betraying Harry. This somehow could state that there were some bad eggs coming from the other houses.

12. “Troll in the dungeon!” mistake

In Harry Potter and the Philosopher’s Stone, while running into the Great Hall, professor Quirrell screamed that “Troll in the dungeon!” Immediately, professor Dumbledore orders all the students to come back their dormitories. However, as the headmaster of Hogwarts, how could professor Dumbledore forget that Slytherin House dorm was in the dungeons?

13. Wizard children weren’t taught basic reading, writing and math skills

Before attending Hogwarts, Harry, Ron and other wizards and witches at least were taught basic math and reading skills. While the fact that children from the magical families don’t have to go to schools till they’re eleven years old. But their education seemed to be done once they set foot on Hogwarts. In the next seven years in Hogwarts, these students were never taught advanced music, foreign languages, math or literature.

14. Secret Keeper problem

Choosing the Secret Keeper was the fatal mistake of Lily and James Potter after they were forced to attend the First Wizard War. After being told, the Secret Keeper took his duty as becoming the only living embodiment of that secret. No one else could be revealed the secret, not even the information of the teller.

Lily and James made a mistake and had to pay for their lives. But why don’t they become the Secret Keeper for themselves? Why did they decide to choose the third?

You might argue that it’s impossible for the owner of the house to be his/her own secret keeper. It’s not correct because Bill decided to become the Secret Keeper of Shell Cottage, his and Fleur’s house.

15. Why did Dumbledore send their young students into the Forbidden Forest?

Every year, Dumbledore had announced to all of Hogwarts students that the Forbidden Forest is forbidden because this place is extremely dangerous (with three-headed dogs, basilisks, etc.). This is simply the highest priority of safety that everyone, not only new students but also older ones, must follow.

So, do some naughty 11-year-old kids who just joined Hogwarts really deserve a life-threatening punishment wandering the Forbidden Forest in the middle of the night? You might argue that Hagrid would protect them, but you forget that the kids split up, leaving some with no protection. Anyway, I don’t see the logic of it at all!
