The Challengers of the Unknown were acquaintances who miraculously survived a plane crash unscathed. They concluded that since they were "living on borrowed time", they should band together for hazardous adventures. The four — Kyle "Ace" Morgan, Matthew "Red" Ryan, Leslie "Rocky" Davis, and Walter Mark "Prof" Haley — became the Challengers of the Unknown.
