If Voldemort had made the Chosen One Neville, then he would not have survived Voldemort's murder attempt on him as a child. Snape would not have asked for him to protect anyone as he did not care for the Longbottoms, this may have meant he never became a double agent too.
The only reason why it was Harry is that Voldemort thought he was the child the prophecy was talking about. By targeting him and trying to kill him, Voldemort marked him as his equal, while Neville got to live his life without that burden (though that doesn't mean he had an easy life).
Why did Voldemort choose Harry instead of Neville?
Initially, Voldemort twisted Harry into the position by first looking at his lineage. Tom Riddle and Harry Potter were both half-bloods, which meant Harry was more like him than the pureblooded Neville. From there, Voldemort focused specifically on the Potters, who had defied him to no end.
The Prophecy states that the one with the power to vanquish the Dark Lord would be born at the end of July to parents who had defied Voldemort three times. Both Harry and Neville Longbottom fit this description, but Voldemort chose to apply the Prophecy to Harry.
Who else could have been The Chosen One in Harry Potter?
When it comes to Harry Potter's most popular characters, Cedric Diggory is often one of the first to come to mind. His charismatic and chivalrous personality makes him, at face value, one of the top candidates for who could have been the series' Chosen One.
If Voldemort had made the Chosen One Neville, then he would not have survived Voldemort's murder attempt on him as a child. Snape would not have asked for him to protect anyone as he did not care for the Longbottoms, this may have meant he never became a double agent too.
Voldemort intended Draco to die in the attempt to kill Dumbledore so that Lucius would be punished for his failure to retrieve the prophecy from the Ministry of Magic.
Neville is a pure-blood wizard born to Frank and Alice Longbottom, who were prominent Aurors and also members of the Order of the Phoenix during the first war against Lord Voldemort.
While most fans agree that Harry is the unrefuted Chosen One, the final Deathly Hallows film (in particular) sways heavily toward highlighting a heroic Neville, revitalizing the debate regarding which boy is better suited for the iconic title.
Neville isn't the Chosen One because Voldemort 'chose' Harry, by “marking him as his equal”. First of all, Voldemort didn't hear the whole prophecy. He heard only till the part that describes the time of birth, and the parents of the chosen one. He did not hear the part of the dark lord marking him as his equal.
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
How did Lily and James Potter defy Voldemort three times?
James and Lily defied Voldemort 3 times
"If you're counting, which I do, any time you arrested one of his henchmen, any time you escaped him, any time you thwarted him. That's what he's looking for," she said. "And both couples qualified because they were both fighting."
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
For the second time in Voldemort's life, the unforgivable curse rebounded on him, as the Elder Wand wouldn't kill its master. Since Harry and his friends had already destroyed all of Voldemort's Horcruxes, this finally ended Lord Voldemort's life, with Harry finally defeating the Dark Lord.
In his first years at Hogwarts, Neville Longbottom came off as a clumsy student who performed poorly when using magic. However, his bad performance was nothing to do with his magical ability; instead, it had to do with the wrong wand.
Hermione was a prominent example of this as, on the surface, she appeared like someone who would fit right into Ravenclaw. But beyond her interests, her values define her as someone with a take-charge personality and bravery to spare. Unlike Ravenclaws, she didn't apply knowledge in unique ways.
Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom. Due to Neville's death, the final Horcrux Nagini was never destroyed, and as a result Voldemort is never defeated, kills Harry and takes over the Wizarding World.
Also, James Potter was a pure-blood. One possible theory indicates that the author of the Directory considered the Potters and other "pure-blood" families (such as the Princes, the Crabbes, the Goyles, the Moodys, and the Browns) to have some amount of Muggle ancestry.
Probably. All the pure-blood families are related, and on the Black family tree, Draco's great-grandfather's first cousin Callidora Black marries one Harfang Longbottom, who is likely a relation of Neville's.
“He wants to have a stable job at Hogwarts. And Luna is a bit too kooky and out there for him and she wants to go out and travel the world. And their lifestyles just wouldn't mix.
Astoria Malfoy (née Greengrass) (c. 1982 – August 2019) was a British pure-blood witch and a member of the Greengrass family, one of the Sacred Twenty-Eight.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use. He has tons of happy memories... He had an amazing childhood. However, she also said Snape was the only Death Eater who could produce a Patronus.
Because he and his family defected from the Death Eaters they were pardoned for their crimes after Voldemort's final defeat and did not serve a stint in Azkaban. He and Narcissa later had a grandson, Scorpius Malfoy, after Draco married Astoria Greengrass.
Yes. Draco's mother is Sirius first cousin on his mother's side (Narcissa and Sirius are also second cousins on his father's side, as Sirius parents are first cousins).
