There are many ways forfantasybooks to make an impression, and the ones that feature compelling villains or surprising plot twists tend to leave their mark. Some novels within the genre even manage to combine these strengths, featuring villain-related plot twists that leave readers speechless. Not every villain twist is pulled off effectively, buta handful of fantasy books manage to cement themselves as unforgettable with these kinds of reveals.
TheHarry Potterseries is known for upending reader expectations when it comes to its secondary villains, and it’s far from the only fantasy story to flip the script on seemingly innocent characters or vice versa. Some revelations go even further than that, confirming a villain has shocking connections or powers that change the direction of the story. The best twists feel earned, as they’re set up throughout the narrative. Somehow, they still manage to be surprising though, causing them to stick with readers long after they happen.

8Mistborn: The Final Empire By Brandon Sanderson
Twist: Rashek Is The Lord Ruler, Not Alendi
Brandon Sanderson’sMistbornbooksfeature a number of impressive twists and turns, but the villain reveal at the end of the first book is probably the most memorable. Sanderson includes journal entries throughoutThe Final Empire.These allow readers to immerse themselves in the story as Vin and the crew unpack the writings of Alendi, the man originally believed to be the Hero of Ages. For most of the firstMistbornbook,we’re led to believe that Alendi and the Lord Ruler are the same person. However, Vin’s showdown with the Lord Ruler turns this notion on its head.
10 Genius Mistborn Theories I Really Hope Are True
Brandon Sanderson’s Mistborn series is ripe for theory-crafting. With Era 3 underway, here are some possibilities for the saga and the wider Cosmere.
Vin is able to defeat the Lord Ruler when she realizes that he isn’t actually Alendi; instead, he’s a background character Alendi talks about in his journal entries.The revelation that the Lord Ruler is a Terrisman named Rashek makes sense of his powerful abilities— and it explains Alendi’s failure to save the world. The fact that it’s followed by an even bigger twist — that the Lord Ruler is fending off a greater evil — makes this one of the most unforgettable endings to a fantasy book yet.

7Harry Potter & The Sorcerer’s Stone By J.K. Rowling
Twist: Quirrell Is After The Stone, Not Snape
TheHarry Potterbooksare set up like mysteries, so each of them features a surprising twist at the end. This starts inHarry Potter & the Sorcerer’s Stone,which brilliantly uses Snape as a red herring throughout its run. Once the Golden Trio learns that the Sorcerer’s Stone is being hidden within Hogwarts, they jump to the conclusion that Snape is trying to steal it. To be fair,the evidence against Snape seems solid. The book inserts many clues that Snape is the one who’s after the stone, only to reveal he’s actually trying to save it.
Harry realizes this at the end ofSorcerer’s Stone,when Quirrell is waiting for him after the potion trial. Looking back at the evidence against Snape, readers will pick up on a common theme:Quirrell is also present for many of these scenes, which set up this book’s ending twist perfectly.Harry Potter & the Sorcerer’s Stoneisn’t the only installment to feature a jaw-dropping twist regarding its villain. However, it’s the first one to do so, making it even more surprising than the sequels' big reveals, since readers aren’t expecting it.

6The Lightning Thief By Rick Riordan
Twist: Luke Is Working For Kronos
The Lightning Thiefsets up Kronos asPercy Jackson & the Olympians’Big Bad, but the book’s minor villain reveal is far more heartbreaking. Percy discovers that his friend, Luke Castellan, is working with Kronos to get revenge on the gods. And Luke’s betrayal is teased earlier than this, when the flying shoes he gifts Percy nearly drag Grover down into Tartarus.Riordan cleverly works this detail into the firstPercy Jackson & the Olympiansbook’sclimax, setting up Luke’s turn before Percy actually confronts him.
Such villain twists are always more satisfying when authors lay the groundwork for them, and Riordan does so impressively inThe Lightning Thief.

5The Last Magician By Lisa Maxwell
Twist: Nibsy & Professor Lachlan Are The Same Person
Lisa Maxwell’sLast Magicianseries is one of the most underrated YA fantasy stories out there, and it makes theperfect replacement forSix of Crows.The first book,The Last Magician,also features a bombshell plot twist at the end: that Nibsy Lorcan, who Esta meets in the book’s past timeline, is the same person as Professor Lachlan, her father figure who sends her back in time. This makes it doubly heart-wrenching when Nibsy betrays Dolph, Esta, and the rest of his crew in order to steal the Ars Arcana for his own sinister ends.
10 Underrated Fantasy Book Series That Should Be On Everyone’s Radar
Not every fantasy book series can be The Lord of the Rings or A Song of Ice and Fire, but there are 10 underrated fantasy sagas worth reading anyway.
As with many great fantasy book twists,the clues for this revelation are scattered throughoutThe Last Magicianfor those looking out for them. But with Esta traveling to 1902 with biased expectations — ones planted by Professor Lachlan himself — it’s not hard to believe that Harte or another character is the group’s traitor. Nibsy is easy to overlook until it’s too late, which is what makes this villain twist so genius. And it has lasting repercussions for the remainder of the series, proving itself a meaningful turn for Esta’s story.

4The Golden Compass/Northern Lights By Philip Pullman
Twist: Mrs. Coulter Is Lyra’s Mother
The Golden Compass— known asNorthern Lightsoutside the United States — hardly tries to sell Mrs. Coulter as one of the good guys. However, while it’s apparent almost immediately that she’s a villain,the firstHis Dark Materialsbook still manages to land a surprise in regard to her character. The revelation that she’s Lyra’s mother comes as a shock, and it successfully raises the emotional stakes of the story. Lyra’s narrative is already tragic inHis Dark Materials,but the fact that she’s often fighting her own family makes matters even worse.
This devastating twist fits well with Lyra’s coming-of-age narrative, which forces her to forgo her innocence and see the darker truths of her world. That she’s related to the likes of Mrs. Coulter is one of these harsh realities she must face, though her mother does somewhat redeem herself later in the series. Even so, it’s still surprising to learn Mrs. Coulter’s true connection to Lyra, especially after she treats her so horribly.

3Shadow And Bone By Leigh Bardugo
Twist: The Darkling Is The Black Heretic
One might think it’s obvious that a character called the Darkling is a villain, butLeigh Bardugo’sShadow and Bonemanages to make this revelation surprising regardless. When Alina first meets the Darkling inShadow and Bone,she believes he’s on the side of Ravka. He insists he wants to destroy the Shadow Fold, but it’s later revealed that he’s the one who created it. The twist that the Darkling and the Black Heretic are the same person makes a lot of sense, but it still manages to be a shock.
Although the Darkling beingShadow and Bone’s villain isn’t necessarily a surprising twist, the specifics surrounding his character are.

After all, few readers expectthe Darkling to be immortalwhile working their way throughShadow and Bone.This makes his involvement in the Fold’s creation seem less likely, even if all the clues about his true nature are there from the beginning. Although the Darkling beingShadow and Bone’s villain isn’t necessarily a surprising twist, the specifics surrounding his character are. That ensures this revelation a memorable one — as does the fact that it hits Alina so hard after she begins to develop a bond with him.
