Over two decades have passed since the release of the first Harry Potter book, yet fans continue to uncover fascinating details about the series’ characters and lore. In 2007, J.K. Rowling stunned the global fanbase by confirming that Albus Dumbledore, the beloved headmaster, was gay. Since then, she has persistently shared intriguing tidbits about the wizarding world.
A new theory, gaining momentum, delves into the true significance behind Harry’s lightning bolt-shaped scar (though Rowling has yet to comment on it).
In a recent tweet, Today Years Old suggested that the scar is connected to the Avada Kedavra curse—also known as the Killing Curse—which Voldemort used in his failed attempt to end Harry’s life when the young wizard was just an infant.
The account shared a screenshot from the Harry Potter Wiki entry detailing the Killing Curse, including the specific hand motion required to cast it. The tweet highlights how this motion bears a striking resemblance to the lightning bolt scar etched on Harry’s forehead throughout the films.

Harry’s scar materialized the instant the Dark Lord cast the curse on him and his parents, establishing a clear connection between Avada Kedavra and the mark (and the scar itself linked Harry to Voldemort). However, whether the scar’s shape directly mirrors the hand movement remains a topic of discussion.
This new insight has left some Harry Potter fans astonished, questioning how they overlooked the similarity for so long. Meanwhile, others have dismissed the theory outright, arguing that the resemblance is merely coincidental—or even denying any likeness between the two shapes altogether.
If past events are any indication, it’s only a matter of time before Rowling steps in to clarify the truth behind this intriguing theory.
