"Battletoads is a video game developed by Rare Ltd. Starring three anthropomorphic toads named after skin conditions (Rash, Zitz and Pimple), the game was created to rival the Teenage Mutant Ninja Turtles games.
The first game was developed by Rare for the Nintendo Entertainment System in 1991. It was subsequently ported by Mindscape to the Amiga in 1992, by Sega to the Sega Mega Drive/Genesis and Sega Game Gear both in 1993, by Rare to the Game Boy in 1993 retitled as Battletoads in Ragnarok's World, and by Mindscape to the Amiga CD32 in 1994. Ports for IBM PC and Atari ST were planned by Mindscape but never released. A fully developed Sega Master System version was also kept unreleased by Sega.
It is arguably one of the most graphically advanced video games ever released for the NES, at a time when the video game market was turning to the Sega Mega Drive/Genesis and Super Nintendo Entertainment System. The game became famous for its extreme difficulty and humorous ways of beating enemies, as during finishing attacks, the character's body parts transform into gigantic, exaggerated appendages for devastating attacks and comic effect.
