Showcase keeps cranking out characters, with Rip Hunter debuting in Showcase #20 (March 1959). Rip Hunter is a blonde, handsome, t-shirt-wearing, but sometimes shirtless scientist who invests a couple time spheres. With his companions Jeff, Bonnie and Corky they initiate a series of adventures across time. This first adventure lands them in the prehistoric days facing off thieves who stole a time sphere as well as dinosaurs.
