Giant Robo (ジャイアントロボ, Jaianto Robo) is a manga by Mitsuteru Yokoyama, in which the huge robot of the same name as the title appears. Tokusatsu, Anime, etc. based on this manga were produced.


Since Toei requested a plot for Tokusatsu TV series from Yokoyama, he wrote this manga. Yokoyama made the setting "Giant Robo follows only a hero" for differentiation with his Tetsujin 28 which everyone can control.
