"Crisis from Yesterday"
The Lord of Time, with the help of the Eternity Brain, has brought several "heroes" from the past to defeat the Justice League and Justice Society. These individuals have been granted "super" powers with which to accomplish their task. Tragically he realizes too late that his plan may well mean the end of all time and space.
