Who is Thorn?

Rose Canton, a meek botanist with a split personality, transforms into the fierce, thorn-wielding vigilante Thorn — her dangerous alter ego who wages war on crime, unaware of the violence her other self commits.

Born in the pages of Superman's Girl Friend, Lois Lane in 1970, Thorn is a Silver Age DC creation from the sharp minds of Robert Kanigher and Werner Roth — a character with enough staying power to still be turning up in comics more than five decades later. Across a remarkable 55-year publishing history, she's kept extraordinary company, sharing adventures with the likes of Superman, Batman, Clark Kent, and Bruce Wayne, and leaving her mark across titles like Detective Comics and Adventures of Superman. With a key collector's issue to her name and appearances spanning from the Bronze Age through the modern era, Thorn is one of those wonderfully persistent figures who rewards the curious reader willing to dig into DC's deeper catalogue.
