HISTORY
A group of adventurers who made it their business to find out about all the weirdness in the world after surviving a near-fatal air crash. The members of the team were: Kyle Morgan (Ace), their leader, who was an accomplished pilot; Rocky Davis, a former world-class wrestler with a heart of gold; Matthew (Red) Ryan, a hot-headed former CIA agent and mountaineer; and 'Prof' Walter Haley who was an expert diver rather than a scientist. They were often joined on their adventures by June Robbins; she and Prof Haley were 'killed' in an explosion some time after the Challs went into semi-retirement. Since then, the Challengers of the Unknown have taken several different forms as a group.
