First appearance: (as Pym) TALES TO ASTONISH #27, (as Ant-Man) TALES TO ASTONISH #35, (as Giant-Man) TALES TO ASTONISH #49, (as Goliath) AVENGERS #28, (as Yellowjacket) AVENGERS #59
Height: 6 ft.
Weight: 185 lbs.
Strength level: As Yellowjacket and Ant-Man he had the normal human strength of a man of his age, height, and build who engages in intensive regular exercise. He retained this level of strength even when, as Ant-Man or Yellowjacket, he shrank to insect-size. At giant size as Giant-Man or Goliath, Pym's strength varied according to the height he achieved: at 10 feet tall, Pym could lift (press) 1000 pounds, at 25 feet tall he could lift (press) 10 tons, and at 100 feet tall, Pym could lift (press) 50 tons. The higher Pym grew past 25 feet, the more of his strength he had to use simply to support his own enormous mass.
Known superhuman powers: As Ant-Man and Yellowjacket, Henry Pym possessed the power to reduce himself to the size of an ant, approximately one-half inch in height, by means of the subatomic particles known as the Pym Particles. The nature, source, and mechanics of the Pym Particles remain unrevealed. Originally, when Pym inhaled a gas or drank a potion containing the Pym Particles, the Particles would interact with the electrical impulses of his brain, creating an organism-wide "reducing field." Thus activated, the field reduced his entire body at a uniform rate to the smaller size he desired. Although he usually chose to reduce himself to one half inch in height, he could reduce his size to any size between that and his normal size. Usually, Pym did not compress his mass into his smaller size. Instead his mass was, somehow extended into an extra physical dimension that is opened by the activating of the Pym Particles, from which the mass could later be reclaimed.
To return to normal size, Pym inhaled another gas or drank another potion, either of which contained another type of Pym Particles. These particles interacted with his brain to create an organism-wide "enlarging field," which is energized by mental command. Thus Pym could grow back to his normal height and reclaim all of the mass that was extended extradimensionally.
Strangely, because Pym's mass was extended extradimensionally when he was at ant-size, he retained his full human-size strength at that size, although his weight was reduced in proportion to his insect-like size.
Pym sometimes used the Pym Particles to shrink to sub-microscopic stature. When 99.99 + % of his mass was extradimensionally shunted, he was sent into a "subatomic universe" or "microverse," one of countless alternate universes accessible to Earth only by the mass-shunting process.
Pym also discovered Pym Particles which interacted with his brain to enable him to grow to gigantic height as Giant-Man and Goliath. The growth process required the rapid acquisition of bodily mass, presumably from an extradimensional source. This extradimensional mass fortified all of his cellular tissue, including his bones and muscles, enabling him to support his increased weight, and giving him superhuman strength.
Continuous exposure to Pym Particles over an extended period of time enabled Pym to generate his reducing and expanding fields spontaneously, without exposure to a new quantity of Pym Particles. Hence, Pym could increase or decrease his size simply by will power.
Growth to gigantic size imposed great strains on Pym's body over the years, however, leading to the limitations on his growth abilities described under History.
It is unclear whether or not Pym still retains his superhuman powers. Possibly he has tost them since he has not used them in so long.
Abilities: Dr. Henry Pym is one of the world's foremost biochemists and also possesses considerable expertise in subatomic physics and robotics.
Paraphernalia: As Ant-Man Pym wore a "cybernetic helmet" which permitted him to achieve rudimentary telepathic communication with ants and other higher insects and to control their minds. As Yellowjacket Pym carried miniaturized versions of the helmet's devices in his cowl, enabling him to perform the same feats.
As Yellowjacket Pym carried electric "stingers'' in his gloves which emitted electrical bolts of variable current. His costume also had artificial wings which enabled him to fly.
As Goliath, Pym can shrink an entire laboratory or an array of firearms to the size a microchip when not in use. The various compartments on his uniform straps contain a wide variety of miniaturized equipment.
