Before the modern multiverse, Batman’s world exploded into giants, aliens, and alternate destinies. Guided by award-winning co-creator Bill Finger and iconic artist Sheldon Moldoff, this era fuses classic heroism with wild Silver Age concepts, capturing the moment the Caped Crusader embraced pure imagination. When imagination meets atomic-age anxiety, Batman goes everywhere—from haunted Bat-Caves to lost seas, distant planets, and even alternate histories where his parents never died. Award-winning Batman co-creator Bill Finger and powerhouse Silver Age art teams blend bold concepts, clean adventure, and quiet emotional beats into some of the most charmingly audacious stories in the character’s history. Shape-shifting aliens, monstrous experiments, strange dimensions, and bizarre "imaginary" scenarios push the Dynamic Duo into constant reinvention. Along the way, readers will encounter the first appearances of Mr. Zero (the prototype for Mr. Freeze), Bat-Mite, and Calendar Man; and a fresh retelling of Batman’s first case.  Collects Batman #117-132; Detective Comics #258-281; Adventure Comics #253; Superman's Girl Friend Lois Lane #6
