Jimmy Olsen of Earth-2
Jimmy Olsen (of Earth-2)
The Earth-2 counterpart of Jimmy Olsen. The journalist and friend of his Earth's Superman who is the colleague of Clark Kent and his wife, Lois Kent on the Metropolis Daily Star. Jimmy (or James, as he prefers later in his life), who is dying of an unnamed disease, is saved by his Earth-1 counterpart and the Earth-1 version of Superman.
It is unknown if Jimmy has ever married or fathered any children, and very little is known about his immediate family other than the fact that he has no siblings (SF No. 186/2, Nov/Dec 1977: "Save My Friend, Kill Your World!; SF No. 187/2, Jan/Feb 1978: "A Phoenix of Steel!").
