Superman III (1971)
The final duplicate of Superman I and Superman II, composed of an "artificial, unstable protoplasm."
Superman III dies saving his alternate version of Earth, one of many Parallel-Worlds, "from a catastrophic explosion caused by a new from of energy!"
Superman learns of these events when he is accidentally transported by historians to the Twenty-Fourth Century of this parallel Earth along with parallel versions of George Washington, Abraham Lincoln, and George Custer (Act No. 399/1, Apr 1971: "Superman, You're Dead ...Dead ...Dead!").
