Based on a Mitsuteru Yokoyama manga, but not lucky enough to get adapted by Yasuhiro Imagawa, the four-part Babel II (that's Babel The Second) OVA has all the ass-pulling superpowers and sudden giant robot appearances you get from Giant Robo, but without the thematic or character-driven gravitas. Which means that while it is compellingly weird, it's a bit of a trifle. It was still fun to review, though!
