Blackhawk 1957 #205 - back issue - $4.00

Superboy gives fire prevention tips.

The Blackhawks search a swamp for escaped convicts, but a strange gas turns Hendrickson, Olaf, and Stanislaus into beasts. Blackhawk is captured by a scientist who has invented a transformation gas. The gas affects evolution and has caused the previous transformations.

Mopey's get-away driver is too law-abiding.

Professor Millard's gas turns Blackhawk into a futuristic man with telepathic powers. While Professor Millard makes preparations to turn himself into a super-genius, Blackhawk uses his mental powers to gather the rest of the Blackhawks together. This leads to a showdown between the super-minds of Blackhawk and the Professor.

The Blackhawks bomb a beach full of ammo dumps and vehicles, but are stunned when reconnaissance photos the next day show all the supplies back in place. They have to make a sea raid to find out what happened.
