Getter Robo is a beloved old school manga series from the 1970s which was adapted to a 51-episode anime series that ran on Japanese TV in the mid-1970s. Getter Robo is a fundamentally important work in the scope of current Japanese pop culture because it was the first time audiences saw multiple robots combining to form one larger robot. This led to a number of immensely popular iterations of this idea, from Voltron to several groups of Transformers (remember the Constructicons?) That idea came from somewhere, and that somewhere is Getter Robo. Super cool Getter Robo toys!
