Bizarro Back Issues: Astro Boy Against Lord Satan! (1962)
If you've read one Astro Boy story, then the odds are pretty good that it's 1964's "The Greatest Robot On Earth." It's considered to be a high point not only for Astro Boy, but for Osamu Tezuka's career, a massive, sweeping story full of Earth-shattering fight scenes and a villain who, despite his horrible acts, isn't entirely evil. It was even revived as the basis for 2003's Pluto, one of the greatest comics of all time, where Naoki Urasawa retold the story as a murder mystery from an entirely new perspective. It is, by any measure, one of the all time greats.
But let's be real here: Why would anyone ever talk about that comic when the very next volume has a story where Astro Boy fights Lord Satan in an amusement park full of robot deathtraps?
