Harry Potter World Cup: Ron Vs. Sirius

Harry PotterWelcome to MTV's Harry Potter World Cup! We've selected 64 of the best "Harry Potter" characters and matched them up in a series of duels for a chance at magical glory, but it's up to YOU to decide who the greatest "Potter" character of all time is in this pool of wizards and witches. Will the Death Eaters destroy Hogwarts, or will good triumph over evil? In the end, the choice is yours, so keep voting at MTV Movies Blog and make your voice heard!

The Boy Who Lived may be gone, but there are still four people very near and dear to his heart in contention for the Harry Potter World Cup championship. Snape and Hermione are already slugging it out, and now it's time to turn our attention to the only other duel in this round: Harry's best friend versus Harry's godfather. Let the battle begin!

Voting for the Final Four will last until Sunday (July 10) at midnight. The final duel launches promptly at 12:01 AM EST on July 11 and will be announced later that day during our live-stream coverage of the "Harry Potter and the Deathly Hallows Part 2" red carpet in New York City.

(1) Ron Weasley vs. (3) Sirius Black

In one corner stands the last remaining Weasley, a young wizard who matured over the course of seven novels and movies and countless adventures alongside best pal Harry. In the other is Sirius Black, Harry's godfather and James Potter's best friend. There's a lot of history at play here, but it's not their past that matters: it's the present. Both men hold special places in "Potter" fandom's collective heart, but in the end, only one can advance. Should it be Ron, a character who transformed dramatically throughout Jo Rowling's fantasy epic? Or does your vote go to the Prisoner of Azkaban and his unstoppably cool mustache? It surely won't be an easy battle for either of these wizards.
