In early February the members of the disbanded JSA are missing again. An emergency meeting of the All-Stars is called and the Tarantula is invited for the first time. The meeting is interrupted by an attack by a crazed 'Fairytales' Fenton and after he is dealt with, the All-Stars head over to the grounds of the 1939 New York World's Fair where a mysterious threat is being broadcast in Morse Code. This results in the All-Stars meeting, for the first time in combat, the Brain Wave. Within the Perisphere the group find the comatose bodies of the JSAers and are given an ultimatum – enter into the dream world crafted by the villain and save the heroes from within, or else be killed. Johnny and company enter into the dreamscape but they fail as quickly as did the JSAers. Only the timely intervention of the Green Lantern saves the heroes and destroys the dream machine. After Brain Wave's defeat the group chooses the Perisphere and Trylon as their new HQ.
