In the '80s, Bandai tormented the world with the "Go-Bots", a shameless rip-off of the much more popular Transformers series. Maybe they would have had better luck pimping these transformable NES cartridges instead.
Released throughout the decade by the Japanese toy company, these "Kasetto Sentai" (Cartridge Corps) figures were small replicas of actual Famicom (the Japanese NES) cartridges, which were able to transform into the characters of the games they were representing. So the Mario cart became Mario, the Mega Man cart Mega Man , and the Gradius one became a freakin' Vic Viper. So great.
Below you'll see how these figures compared in size to the actual Famicom cart, along with the full range, which also included Bowser, Ghost 'N Goblins and Dig Dug.
