However, just like that shy kid from your school who went on to become a porn actor, later books seem to hint that there might be something more to Neville than meets the eye ...
The Awesome Fan Theory:
Basically, that Harry Potter dude was just a distraction. The "chosen one" was Neville all along.
See, the plot of all seven books revolves around the idea that Harry's life fulfills this prophecy:
"The one with the power to vanquish the Dark Lord [Voldemort] approaches ... born to those who have thrice defied him, born as the seventh month dies ... and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not ... ".
"Also, he'll have a goddamn sword."
The thing is, all that stuff applies to Neville, too. His parents had thrice defied Voldemort, and he was born on July 30, one day before Harry. So what power does Neville know that Voldemort doesn't? According to the theory, that could be either "the power of love" (as in Harry's case) or "herbology."
Or both, considering the way he looks at those plants.
