Four brave men living on borrowed time make up the adventurous team known as The Challengers of the Unknown that debuted in DC's Showcase #6 from January 1957 by Jack Kirby and Wally Wood. The fearless four Challengers or "Challs" they were often called were, Red Ryan a daring mountaineer and daredevil stuntman; Ace Morgan the high-flying jet pilot; heavyweight boxer and world wrestling champ Rocky Davis; and Prof Haley rounded out the team as a deep sea diver and scientific genius. A group of complete strangers that somehow survived a deadly plane crash together, that all mysteriously had their wrist watches stop at the exact moment, which lead them to believe they were chosen to dedicate their unique skills to help others in their "second chance" at life! From their Challengers Mountain base loaded with high-tech equipment deep within an extinct volcanic crater in Wyoming, the Challengers defended Earth against outer space alien threats to various super villains like the bizarre Multi-Man or the infamous Legion of the Weird. With at least ten different series over the many years at National with some early fantastic and then just average writers and artists producing the stories, the "Challs" still endure as this team uses every last minute fate granted them to benefit mankind.
