Green Lantern is whisked away into the year 5700AD to help the “Solarians” with some menace in Green Lantern #8 (July 1961). They do this by swapping his 20th century memories out and hypnotizing Hal Jordan into believe he is Pol Manning, famed asteroid explorer of the 58th century. It’s a neat little trick that allows Green Lantern to have two lives with room for all sorts of storylines in the future.
