A man of action and a man of science, Dr. Henry Pym invented an amazing growth serum and a cybernetic helmet, and with them he became — the Astonishing Ant-Man! Pym soon teamed with Janet Van Dyne, the winsome Wasp, and the two tiny titans went on to battle an array of mini- and maxi-sized menaces from the Scarlet Beetle to the Black Knight! But adventures in the microscopic world weren’t enough for one of the Marvel Age’s first super heroes. Soon, Ant-Man became the biggest Avenger there ever was — Giant-Man! And his foundational adventures are all here in this debut Epic Collection!
