Superboy arrives in the future for the wedding of Saturn Girl and Lightning Lad only to find a world totally different from the one he is used to visiting. The future is now an armed camp and the Legionnaires insist it has always been that way. With Superboy unable to convince his teammates that something is wrong, the wedding proceeds as planned, only to have the bride and groom kidnapped by the Lunarites. Convinced that the altering of history is the real issue, Superboy leads a group of legionnaires back in time, while the rest of the group attempts to rescue their teammates. Can Superboys team correct the flow of time and save all the future? Includes a 2-page pin up of the entire Legion by Mike Grell and an 8-page feature containing information on each of the legionnaires by Paul Levitz, illustrated by James Sherman and Jack Abel.
