Atomic Robo and the Knights of the Golden Circle is written by Brian Clevinger and drawn by Scott Wegener.
Semi-spoiler alert: That thing the dinosaur did in the previous book sort of but didn’t quite work, resulting in Atomic Robo traveling back in time.
Most of the “back in time” books of Atomic Robo are actually just stories we haven’t heard yet, about a younger Robo during a younger time, a time post-Edison and Tesla, perhaps of World War II or the Cold War, punching Nazis or threatening Soviets.
This book, however, takes place in the Old West, before Edison and Tesla. Before electricity. Before robots, certainly. And Robo, who certainly didn’t plan ahead for his predicament, has only a limited amount of power, a strong desire to not change the past, and of course, an overdeveloped sense of justice.
Thus he finds himself with two famous westerners in 1884, fighting cyborg cowboys and saving the world. As you do.
There’s quite a bit of tension in this volume, some dry humor, and enough cyborgs to choke a steam engine. Definitely worth picking up.
