Battle Arena Otaku Fight! Fight!: Sailor Moon vs. Kamen Rider, Sebastian Michaelis (Black Butler) vs. Rick Hunter (Robotech)

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!

Will it be the lunar heroine or the bug? That's the choice you'll be making as Sailor Moon and Kamen Rider face off in this first matchup. Really, it all comes down to what you like more: happy-go-lucky heroines with sparkles and light and magic and a mysterious dude in a tuxedo. Or, are you leaning towards big science action heroes, cool bikes, and grotesque enemies that need to be chopped into oblivion?

Well, the choice is obvious when you think about it. (Seriously, we have no idea which way this one is going to go).

Then we've got another face-off involving what we like to think of as the "giant freakin' robot" problem: to wit, one of our challengers is or has a mech and the other doesn't. In the universe's grand game of "mech, butler, something else," "mech" usually wins time and again. But we can't imagine you'll see Sebastian sweating it too much. Maybe that's why he'll have the edge this time around against Robotech's Rick Hunter: that simple and easy unflappability in the face of seemingly overwhelming odds.

Or maybe he'll get stomped down by the mech like all the rest.

But that's up to you, our voting audience. So, what are you waiting for? You decide!
