The Nuclear Family is a team of villains first encountered in The Outsiders Vol.1 1.

Dr. Eric Shanner was an old man who was strongly opposed to nuclear energy. In order to convince the world of its dangers, Shanner created the Nuclear Family, a group of sentient robots whose individual powers mimicked the stages of a nuclear explosion. Shanner intended to use the robots to cause a meltdown at Esperanza Canyon Nuclear Power Plant to cause Californian’s to die from radiation poisoning as his own family had.
