Mr. Freeze

A Silver Age menace born from the pages of Detective Comics in 1968, this Mr. Freeze — crafted by the legendary Gardner Fox and artist Chic Stone — emerged during one of comics' most imaginative eras and has kept chilling company ever since, sharing panels with the likes of Robin, Bruce Wayne, and Dick Grayson across nearly four decades of DC storytelling. His catalog presence spans Detective Comics, Batgirl, and The Batman Chronicles Gallery, with one collector-significant key issue marking his place in the hobby. Nearly 38 years of publication is a testament to just how enduring a cold-blooded villain can be in the Batman corner of the DC universe — and for fans who love tracing a character's Silver Age roots, this is one worth tracking down.
