Count Werner Vertigo first appeared in World's Finest Comics #251 (July 1978) and was created by Gerry Conway, Trevor Von Eeden, and Vince Colletta. Vertigo is the last descendent of the royal family of Vlatava, and suffers from an inner-ear disorder. He discovered that he could modify the device to project waves of nausea on anyone in his vicinity, and first battled Green Arrow in Star City. He later was able to project his "vertigo effect" without need of the device, and gained the ability to fly. After the destruction of his homeland, Vertigo has spent time both as villain (as a member of the Injustice Society and the Suicide Squad) and a hero of sorts with Checkmate.
