Challengers of the Unknown #52

In "Two Are Dead—Two to Go!", the Challengers of the Unknown face their deadliest trial yet as they confront the monstrous Brutals—once ogres, now restored to their original tribesmen form—while a hidden enemy watches through Brainex’s monitor. With the stakes rising and time itself under threat, the team is pushed to the brink as two of their own fall in battle, leaving Rocky and the Professor to unravel the mystery behind the attack. Written by F. E. Herron and illustrated with dynamic precision by Bob Brown—whose inks define the stark tension of the story—this 1966 DC classic features a cover by Bob Brown that captures the moment of peril.
