BATMAN (1940) #537

Man-Bat is in the Arctic about to prey upon members of a research expedition while being pursued by three deadly killers with orders to destroy him–assassins who are, in turn, hunted by the Batman. Man-Bat’s frozen body is discovered in a block of ice at the North Pole. A group of scientists inadvertently revives him and he goes on rampage while attempting to recreate the formula for his cure.
