Superman & Batman: Generations is the umbrella title of three Elseworlds comic book limited series published by DC Comics in the United States, written and illustrated by John Byrne. A major concept of the series is the avoidance of so-called comic book time; it places Superman, Batman, and the other members of the DC Universe in a single timeline, showing the characters aging and being replaced by their progeny. The Elseworlds story Batman & Captain America, co-published with Marvel Comics and written/drawn by John Byrne, was released in 1996. The story features Batman and Robin teaming up with Captain America and Bucky to fight the Joker and the Red Skull in 1945. The epilogue of the tale features Dick Grayson as Batman and Bruce Wayne Jr. as Robin. The duo find the frozen Captain America in the 1960s while searching for the Joker Jr. It is from this epilogue that the Generations concept was spun-off and developed.
