Battle Arena Otaku Fight! Fight!: Speed Racer vs. Kamen Rider, Kikaider vs. 8-Man

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!

In one corner, we've got a demon on wheels with a tricked-out car and a pit crew featuring a toddler and a monkey; in the other, a mutant-cyborg hybrid on two wheels out to stop a terrorist organization based on evil super science. In the battle between tricked out race cars and mutated motor bikes, we all win.

Speed's never been out of the spotlight for too long, most notably with his return to U.S. comics last year, and before that the love-it-or-hate-it Wachowski brothers movie (you can count me in the love it camp), so you might already be primed to cast your vote for one Mr. Speed Racer right off the bat. But don't count out Kamen Rider, his eponymous live-action series having enchanted kids in Japan for over four decades, which a 40th anniversary Kamen Rider all-stars movie making its debut last year along with a new TV series.

If artificial heroes are strictly your thing, we've got a contest between Shotaro Ishinomori's Kikaider and Kazumasa Hirai's 8 Man, both characters that haven't really had a huge presence for a while but have 40 and 50 year legacies in Japan thanks to appearances in manga, anime, and live-action productions over the years. Perhaps a little less prominent than our other two contenders this week, they're no less big a deal when it comes to these takes on human-mechanical hybrids, both spawned, after a fashion, by Tezuka's Astro Boy. With no recent appearances in film or on TV, now's your chance to give one of these characters a chance to shine for the first time in a while.

Voting closes April 9 at 11:59:59pm
