The tenth volume in the Atomic Robo series is back in the present day, or at least 2015, with the robot hero out of action and his buddies scattered. His adventures in the Wild West (see Atomic Robo and the Knights of the Golden Circle) left him out of power, without a body, and time-travelling the long way round, while the Tesladyne Organisation has been turned into Task Force ULTRA, a nefarious governmental agency. In this book ULTRA decides that the fight against the giant Japanese monsters known as biomegas is too important to be left to Science Team Super Five, while escapees from Tesladyne’s Venezuelan branch try to revive Atomic Robo before it is too late. As the biggest biomegas to date attack, people are going to have to learn to work together, and Atomic Robo will have to go into space.
