House of Mystery #164

Three brand-new super-heroes — Zip-Tide, Super-Nova, and Robby Robot — each get their own dramatic panel on this January 1967 DC cover, brought to life by Jim Mooney's energetic linework. At the top, a blond Robby Reed clutches his legendary dial, the boy whose power to transform into a thousand different heroes makes him, as the cover boldly declares, "the most original character in comic book history." Looming over it all is the threat of Dr. Cyclops and his deadly Doomsday Stare, setting up a villain worthy of three heroes' combined might.
