Battle Arena Otaku Fight! Fight!: Voltron vs. Yui, Pikachu vs. Negi Springfield

This is MTV Geek's Battle Arena Otaku Fight! Fight! A tournament-style, knock-down, drag-out, free-for-all, battle royale featuring your favorite anime, manga and Japanese pop-culture characters! Each arena match-up will be posted and voted on by you, the MTV Geek reader, and each winner will advance closer and closer to becoming the supreme reigning champion of the Battle Arena Otaku! Who will take the top spot? Sailor Moon? Godzilla? Hello Kitty? There's only way to find out…FIGHT! FIGHT!

A giant musical talent versus a giant freakin' robot; a young mage-in-training versus a trained monster! Fight!

Showing the universe what it means to rock for justice (I didn't have to strain for that one at all), Voltron's been a defender of the universe for a quarter of a century, even getting a new video game last year to go on his long list of accomplishments (see also: being made of lions, fighting with a laser sword, lions again). His diminutive opponent is teen Yui Hirasawa, star of K-On! the manga and anime and frontwoman of the band Ho-kago Tea Time—she may not be the world's best student, but she's a terrific guitarist and singer. Who should win: the hero of the universe or the guitar hero(ine)?

Then we've got two characters training to be the best: Negi Springfield of Negima! (what is it with our competitors with exclamation points in their series titles?) against the little yellow Pokemon, Pikachu. The young Negi (he's only ten at the start of the series) is both student and teacher as he trains at a Japanese school other students in defense against demons while Pikachu is tiny and forever cute (but in Pokemon years is probably something like 60).

Does the little spark plug have what it takes to take down the magic kid? What about the big robot and the little rocker? You decide!
