Atomic Robo is one of the relatively few comics that has managed to stay good across decades-worth of stories. I highly recommend you read it all. But there is one volume of Atomic Robo that, to me, stands head and shoulders above the rest, because it includes one extra element that no other Robo story has.
One of my favorite things about Atomic Robo, the action-adventure comic about a wisecracking robot built by Nikola Tesla, is the way the series’s premise lends itself to jumping backward and forward in time.
To create a robot adventure scientist, one must first invent the universe.
