Superman II
From superman.nu: Supermanica
The bio-copy of Superman I, a version of Superman from one of many Parallel-Worlds.
Superman II perishes after visiting Riggor, "a 'leper colony' planet," and contacting "a super virus" which dissolves "his body into primitive protoplasm." Because the scientists of the National Research Institute possess records of the original's "cytoplasmic structure," they are able to create yet another new duplicate out of "artificial protoplasm," known as Superman III.
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, Abe Lincoln, and George Custer (Act No.399/1, Apr 1971: "Superman, You're Dead ...Dead ...Dead!").
