Battletoads is a beat 'em up/platform video game developed by Rare and published by Tradewest. It is the first installment of the "Battletoads" series and was originally released on 1 June 1991 for the Nintendo Entertainment System. It was subsequently ported to the Mega Drive and Game Gear in 1993, to the Amiga and Amiga CD32 in 1994 (despite the former having been developed in 1992), and released with some changes for the Game Boy in 1993 in the form of "Battletoads in Ragnarok's World". In the game, three space humanoid toad warriors form a group known as the Battletoads. Two of the Battletoads, Rash and Zitz, embark on a mission to defeat the evil Dark Queen on her planet and rescue their kidnapped friends: Pimple, the third member of the Battletoads, and Princess Angelica.
