This was another reprint of an earlier Doom Patrol story ( #95), though I did not know it at the time. This was indeed a direct sequel to the first AVM Man story, though our heroes suddenly had all of their powers exchanged with each other. Cliff became the Chief, the Chief became Robotman, and Rita and Larry swapped powers (later there would be an actual Negative Woman).
Naturally this causes all kinds of havoc, though eventually our heroes get some more control over their new powers. I always wondered why the Chief never used his robot suit again though.
