Giant Robo is, as the linked article states, both one of the oldest of Japan’s comic franchises and the source of one of the best original animation series in the last 30 years. As such there’s some familiar issues that any franchise faces, starting with multiple continuities that often drastically reshape the premise into something very different from other versions. That’s why I’m specifying the OVA series: “The Animation”.
The reason for this specific incarnation’s enduring appeal is that this story is one of the most boldly Superversive stories to come out of Japan. Just take a good look at the trailer below:
That’s all you need to know, right there. The details that really deliver on the story’s promise aren’t in the trailer, but you will see that every element gets used–and used well–to tell a tale that uplifts the audience, inspires them to face great fears with courage, and press on even when you think you’re done for. That boy, Daisaku, is your protagonist and he gets put through the ringer over the course of this short series, but he does make it happen at the end–albeit with help (and a Pellenor Fields moment that is ridiculous, awesome, and (by that point) makes logical sense).
And it is thoroughly entertaining at all levels. The music is fantastic, the aesthetics are brilliant, and the production team did your Avengers or Justice League style of “heroes band together to stop a world-wide doom” story better than Marvel or DC have to date, in any medium. Daisaku’s the plunky youth you want to cheer for, Big Fire’s villains range from love-to-hate to completely despicable, and the other Experts of Justice may be rough around the edges but they are still heroes.
And, as for the necessity of virtue, the plot centers around two virtue-related matters: the origin of the Shizuma Drive, and the truth about the disaster that nearly derailed its introduction. Big errors got made, and everything about this story is a logical consequence of those errors, but there is no fixing it without fixing those errors- and that final bit shows this story’s value as a Superversive work.
The commercial availability of this animation isn’t what it once was, but you can get it at Amazon in a boxed set on DVD at a reasonable (for commercial anime) price. It’s not a long series: just under 6 hours, total. Agent Carter‘s first season ran longer. Recommended highly!
