- Book One · 32 pages
When new variations of Kryptonite are discovered, Superman asks for Batman's help to test to determine what effect each variation will have on him. The first test is with purple Kryptonite, which affects Superman's sense of linear time, causing him to perceive events in a different order than they occur.
