Collects Superman and Batman: Generations I (1999) #1-4, Superman and Batman: Generations II (2001) #1-4, and Superman and Batman: Generations III (2003) #1-12.
Imagine a world where Superman and Batman aged naturally from their respective debuts in 1938 and 1939! From their first meeting to their confrontations with the Joker, Lex Luthor, and Mr. Mxyzptlk, their personal relationship continually evolves from best friends to bitter partners and finally respected peers. How would their legacies be passed on to future generations of heroes? This collection, from prolific and acclaimed comics writer/artist John Byrne, spans a millennia of alternate DC history and features guest stars from across the Multiverse.
