The Challengers of the Unknown are a team of professional adventurers who regularly cheat death on their missions of discovery and exploration. Members include scientist Walter "Prof" Haley, pilot Kyle "Ace" Morgan, daredevil Matthew "Red" Ryan, wrestler Lester "Rocky" Davis, scientist June Robbins, and mystic Corinna Stark, all operating out of Challengers Mountain in the Rockies. A second generation of the team, made up of racecar driver Clay Brody, pilot Marlon Corbet, entrepreneur Kenn Kawa, physicist Brenda Ruskin, along with business manager Sarah Hargate and funder Edward Sands formed later, meeting surviving members of the original team. The Challengers were created by Jack Kirby, first appearing in Showcase #6 (1957).
