Challengers of the Unknown #67

Challengers of the Unknown #67 (On Sale: February 4, 1969) has its first Neal Adams cover and it is a nice one.

"The Dream Killers" is by Robert Kanigher and Jack Sparling. Tino reports to the other Challengers that he is being chased in his dreams. They aren't worried until he begins bleeding in his sleep. Prof builds a machine that allows the team to view Tino's dream and allows them to see his pursuers.

While Prof works on another machine that will allow the team to enter Tino's dream, the Challengers learn that other people in the city are also plagued by the same dreams. When Prof's work is complete, the Challengers enter Tino's sleeping mind and discover that an alien brain is responsible for the nightmares. They destroy the brain allowing Tino and the other victims to sleep normally again.

The back-up is "Ace:The Beast in the Bomb" also by Robert Kanigher and Jack Sparling. The Challengers track a renegade scientist to an underground labyrinth of caverns. When they split up to search Ace is knocked out and a bomb is attached to his head. The other Challengers rush him back to the city only to discover that the bomb is linked to his heart. Ace is placed into an ice bath and his heart stops. The bomb is safely removed, and Ace is revived. The Challengers then return to the caverns with the bomb. The scientist accidentally triggers it, killing himself, but the Challengers aren't harmed.
