In 1993, a Game Boy version of Battletoads was released, titled "Battletoads in Ragnarok's World". This version was missing several levels and featured single-player support only. The subtitle was given to separate the port from the previous Battletoads game for Game Boy, which was a completely different game altogether.

Okay 'toads! Let's get EVEN! When the evil Dark Queen kidnaps both your best buddy and the best looking girl this side of the Mazallion Star Cluster -what are you gonna do about it? Are you gonna cry? Hide? Call the Starcops? No way! Because you're a BATTLETOAD and BATTLETOADS don't cry, hide, or call for help. BATTLETOADS get real MAD-and then they get EVEN!

So, strap on your Blaster, power-up the Toadster and get on downt o the Dark Queen's planet - but, watch out 'toad - this lady's bad, and she's got a whole mess of really nasty surprises lined up for you - like the Psyko Pigs, the Mutant Ratpack, Robo-Manus and the Saturn Toadtrap, to name but a few. You're gonna need all your fighting skills to defeat her - the Battletoad Butt, the Big Bad Boot and the Nuclear Knuckles. Hey, and don't forget to take along the Jet Turbo, the Space Board and the Speed Bike. Because you're gonna need 'em all, 'toad, if you're gonna rescue your friends and get the frog outta there with your green skin intact!
