Who would win in a fight between Loki, Katniss Everdeen, Veronica Mars, Beatrice “Tris” Prior and Khan? (The answer is Loki. Duh, he’s a god.)

But this is a popularity contest, and the votes are all coming from social media. Now who would win? We’ll soon find out.

MTV is announcing an all-new category for the 2014 Movie Awards: Favorite character. The throw-down also marks the third campaign to exclusively use hashtag counts on Twitter, Facebook, Instagram and Vine to determine the winner.

For the past two years, MTV used social media to determine another new category, Best Hero. That’s now part of the MTV Movie Awards’ stable of regular categories (and this year it's between John Cale in White House Down, Thor, Superman, Bilbo Baggins and Iron Man).

MTV moved the Best Hero category into its online voting structure after a mighty leap in social popularity — from 810,334 hashtag votes in its inaugural 2012 to 3,320,338 votes last year. “Social correspondents” Our 2nd Life – think of them as a boy band for social media instead of music – will announce the new category later Tuesday, when voting gets under way.

(By the way, superfans, those hashtags are: #votekatniss, #votetris, #voteveronicamars, #voteloki and #votekhan.)

MTV took some heat during the “Twilight” years, as the franchise’s rabid fanbase stuffed the ballot box to be sure Kristen Stewart and Robert Pattinson kept circulating onstage. Things have evened out since, though MTV will still count as many votes as fans are willing to throw up on their feeds.

“We kind of like the horse-race that it creates,” Colin Helms, SVP of Connected Content for MTV, told Mashable. “As you get closer to the show, the velocity picks up.”

Fans are also enticed to add photos and videos of themselves with their art, costumes, personal messages or whatever else they’re inspired to do. Though each original hashtag still only counts as one vote, the best stuff will be featured on www.MovieAwards.MTV.com.

“We’re scraping any images posted with the hashtag, so you’ll not only see who’s leading, but also see any content that’s being created around that character,” Helms said.

Conan O’Brien hosts the 2014 MTV Movie Awards on April 13, from the Nokia Theatre in Los Angeles, starting at 9 p.m. ET.
