Justice League of America #197 Newsstand Vol. 22

"Crisis in Limbo!"

As Earth-Two begins to lose all of their heroes (save the ones in limbo in the suspended-animation chambers), the Earth-One Secret Society members wonder why it happened there. They slowly realize they were duped by Ultra, who knew what would really happen. As they attack him, the master villain sends them back to Earth-One, and stranded there, their only chance is to get back to limbo and free the 10 heroes. Released, the heroes then defeat all of the Society members and Ultra is sent into limbo with everything returning as it was.
