An angry Bruce Wayne with a limp intellectual Batman. The Martian Manhunter, and a police detective called John Jones. Wacky Plastic Man and the less ethical "Eel O'Brien". Movin' forward Flash and layabout Wally West. Etc. For Superman, this meant a reliable but nervous Clark Kent and a progressively more Kryptonian superhero. So it was a sound idea to base his new costume on the Byrne era's Krypton Man, back when Kal-El was being manipulated by the Kryptonian artifact known as the Eradicator. More satisfying still is that he day must be saved by the alter egos, including the all too human half of Superman. For it's in his VALUES that we recognize him as a true hero.
The storyline is called Reflections of the Past and can be found in the middle of the JLA Vol.5 collection, or in the currently out-of-print JLA: Divided We Fall (marked as vol.8 of the original trade series). Check it out. Some good stuff still after Morrison left the book.
