The Wizard was responsible for a coup in which his Secret Society, consisting of himself, Professor Zoom the Reverse-Flash, the Floronic Man, the Blockbuster, and Star Sapphire, switched bodies with members of the JLA. This happened in "Justice League of America" #166–168, a storyline that was revisited in "Identity Crisis" (2004), where it was revealed that Zatanna wiped the heroes' secret identities from the villains' minds following their defeat.
