The Kryptonian Code: The “Lost-Modern” Age

In 1985, DC Comics decided to combine the “Infinite” number of continuities they created, purchased, or inherided through a 12-issue mini-series called “Crisis on Infinite Earths”. We all know that. At the same time, they decided to ret-con Superman. Y’know, make him fresh for new readers. Dump the entire Silver Age continuity. They handed the reins to John Byrne.
