Same Mask Different Identity, Same Identity Different Mask

"Be what you are"
(Julius Charles Hare and Agustus William Hare, Guesses at Truth)

Over the years, many comic book heroes and villains have changed their secret identity - either since the hero (or villain, for that matter) abandoned his secret life and took up a new guise, the hero (or villain) was killed or had retired and a new heir took up his old guise, or by a massive re-writing of the world's history (The Crisis of Infinite Earths, Zero Hour, Age of Apocalypse, Onslaught, etc.). In this article I have attempted to collect them all. Obviously, this task is impossible, and this collection is far from complete. I would appreciate any submission, corrections or comments you may have - just drop me an e-mail.
