Let’s be real, “Tom Marvolo Riddle” being re-arranged to “I am Lord Voldemort” was one of the biggest “Oh shit!” moments of our childhoods.

The best plot for me would be...
'Is this true that you shouted at Professor Umbridge?'
'Yes', said Harry
'You called her a liar'
'Yes'
'You told her he who must not be named is back'
'Yes'
Professor McGonagall sat downbehind her desk, frowning at Harry.
Then she said, 'Have a biscuit, Potter'

Biggest plot twist of all: the length of their hair in the 4th film

Greatest plot twist is when Narcissa Malfoy told Voldemort that Harry was dead.

The biggest plot twist was that the cursed child is cannon

I didn’t even know that Dobby belonging to the Malfoy’s was mean to be a plot twist when I first read the book.

The thought of Hermione holding Rita hostage always brings me joy 😁

I reckon both Lupin and Tonks dying was a twist... you'd think 'Oh! they have plot armor, they'd just had a son!' but no. Also Molly killing Bellatrix was pretty shocking, this kind motherly lady just beating the shit out of one of the biggest villains.

I actually was expecting the n°1 plot twist to be that Dumbledore had a plan that Harry would die so Voldemort's looming threat would be over and Snape was SHOCKED.

The Barty Crouch Jr being alive and the villainous mastermind behind all the events of Goblet of Fire was imo the best plot twist from the books.

You’re right, for some reason people don’t really talk about the plot twists in Harry Potter which is interesting because the mystery element of the series is so prevalent in every single book.

What about when we found out that Moaning Myrtle is the girl that died 50 years ago? I remember this hitting me hard

The greatest plot twist in Harry Potter is when Voldemort revealed he can touch him now

The biggest for me is when Dumbledore planned for his death to happen in the hands of Snape.

Ginny being the one who opened the chamber of secrets was a really good one in my opinion. I actually screamed when it was revealed.

Some of my favorite plot twists are the prophecy almost being about Neville which made his role in the fifth book even bigger, Rita Skeeter being an illegal animagus, and Harry being a horcrux. Ron’s rat being the man who betrayed Harry’s parents is also incredible.

I'll never forget first learning that Harry was a Horcrux. That had to be the first moment my heart genuinely sank. To learn that he had a piece of Voldemort's soul inside him would be like learning that your father, who you believed to have been killed, was really the villain you've been fighting the entire time.

And James being a bully is a huge one for me. Snape's unflattering words, even when James saved him, could always be chalked up to his own bias, since people can say bad things about someone else no matter what. So to see him truly be a bully, backing up what Snape told Harry, was devastating.

great list, but there was one that i hoped you'd include: moaning myrtle being the person killed by the basilisk the last time around. i remember being super young reading chamber of secrets and being shocked

The plot twist of how Dumbledore lost his sister was quite a shocker to me

omg saying 'i have the plot twist' every single time in the exact same intonation is driving me NUTS
