Dr. Henry Pym originally discovered and isolated a rare group of subatomic particles, which have become known as the "Pym Particles", which could alter the size and mass of objects or living beings. The Pym Particles allow the user to bypass the Square-cube law of physics.
Originally, Pym Particles were only used to decrease the size and mass of organic and inorganic materials. With some alterations, Pym was able to increase the size and mass of subjects as well. The Pym Particles work by shunting matter into the Kosmos Dimension when shrinking a subject or accruing extra matter from that dimension when enlarging. See Conservation of energy for details.
In their original formula, these Pym Particles existed in a liquid elixir form which would shrink objects or living being to which it was applied. Later, Pym was able to synthesize Pym Particles into a gaseous form for quick shrinking results with inhalation. He created Ant-Man's Suit to allow him to control his size.
Repeated, long-term exposure to Pym Particles can actually result in the subject's body naturally producing its own Pym Particles. Pym, Janet van Dyne, and Cassie Lang's bodies all biologically produce Pym Particles because of this phenomenon.
Pym Particles do exert a large amount of physical and mental strain on the subject's body. Pym personally has had many mental breakdowns because of Pym Particles usage.
History of Uses
Pym enhanced Janet van Dyne in a biochemical process involving his Pym Particles that allowed her to shrink to insectoid proportions and implanted Bio-Synthetic Wings. Furthermore, Pym outfitted her with Wasp's Suit which had wrist devices that allowed her to discharge blasts of compressed air that she called her "wasp's stings".
Porcupine battled Pym and grabbed a number of Pym Particle's capsules from his belt, thinking it's they are growing capsules, the Porcupine took them all. However, the Porcupine realized he's made a grave error when he began to shrink in size. Pym could stop the process and soon loses him when he shrunk to microscopic size.
The Fantastic Four were plagued by a series of incidents where they suddenly shrink to miniature size and suddenly return to normal, they called on Pym for help. He gave Reed Richards a sample of his shrinking gas and leaves to see what he can figure out in his own lab. Reed uses the Particles to shrink down to travel to the Microverse and Pym follows shortly thereafter.
On Planet X, Kurrgo convinced the Fantastic Four to save his race or perish along with them. Reed Richards used the Xanth equipment to manufacture large amounts of Pym Particle in the form of reducing gas. This enabled the entire population to fit inside one ship and escape the destruction of their planet. Reed gave Kurrgo the enlarging gas to be used to allow them to return to normal size when they reached their new destination. However, Kurrgo's hunger for power got the better of him thinking that once on the new planet, he could be the only one to return to normal size, enabling him to become absolute ruler, Kurrgo attempted to keep the giant capsule to himself. But he was not able to carry the capsule to the ship in time, and was left behind as the planet began to undergo massive earthquakes; ironically, Reed Richards later revealed to his teammates that he was not able to create any enlarging gas and that the second capsule had been empty. He figured that since size was all relative, being tiny on their new planet wouldn't matter.
S.H.I.E.L.D. brought in Hank Pym to uses a large batch of Pym Particles against Godzilla. However the monster grabs Dum Dum Dugan before they can take effect. The Godzilla Squad then engaged on a wild goose chase to try and capture the now shrinking Godzilla. He is finally caught by Dr. Hawkins who uses a net on the beast once it has become the size of a regular reptile. 
Rita DeMara stole the original Yellowjacket's Suit from the Avengers Mansion, and modified it for her own use. She clashed with Wasp. The Wasp easily captured the new Yellowjacket when DeMara became hysterical upon using her helmet's cybernetic size-control devices to shrink herself to a tiny size. At that time, DeMara could not adjust psychologically to being so small, although she later learned to do so.
Scott Lang stole Ant-Man's Suit. Garbed as Ant-Man, Lang broke into Cross and discovered Dr. Sondheim was held prisoner by Darren Cross, president of C.T.E., who needed Sondheim to correct his own heart condition. Rescuing Sondheim and defeating Cross, Lang was relieved when Sondheim was able to save the life of his daughter.Lang intended to return the Ant-Man costume to its owner and turn himself in, but Pym offered to let him keep them, provided Lang put them to lawful use.
Biochemist Dr. Bill Foster worked in the Plans and Research Division for Tony Stark's Baltimore factory. He was hired to be the lab assistant of Dr. Pym. Pym was stuck at the height of ten feet for a time and Dr. Foster helped him find a cure to change his size back to normal. At some point acquired the formula to "Pym Particles" which gave him the ability to grow in size like his former employer, taking the name Black Goliath.
Frank Castle has used Pym Particles on few occasions as part of his arsenal by shrinking to escape H.A.M.M.E.R. agents He later infiltrated a stronghold of The Hood by hiding on a pizza, regrowing inside the head of a henchman.
The Big House was a maximum security prison. The Prison, houses superhuman criminals shrunken by Dr. Hank Pym's Pym Particles. Later it was expanded into Lang Memorial Penitentiary, sometimes joking referred to sat the "Ant Farm".
When the Dark Avengers were trapped in an alternate realty that universe Hank Pym shrunk Ai Apaec with Pym Particles. When they escape Toxic Doxie stepped on a still-shrunken Ai Apaec, possibly killing him.
Beast teaches the students their first class of biology. Using Toad as a test subject, Beast and the students shrink down to microscopic size and travel through Toad's body. Beast presents them with the X-Gene, and they travel across the brain and the stomach. The class ends and they get out of Toad's body through one of his eyes.
Taskmaster and Deadpool travel to Southern Nevada to try and score some weaponry-shrinking Pym Particles from a S.H.I.E.L.D. installation in the desert. Deadpool misheard Taskmaster and believed they were called "Pimp Articles."
Due to repeated exposure to Pym Particles from her father's suit Cassie Lang was able to alter he size. She did not learn of this until an argument erupted about Young Avengers membership, and Cassie began to grow at an alarming rate to everyone's surprise, including Cassie's.
Eric O'Grady and Chris McCarthy were S.H.I.E.L.D. Agents tasked with guarding Dr. Pym's lab. When Pym went to leave the lab, Eric and Chris panicked and hey attacked Pym, knocking him unconscious. Inside the lab, they found the most recent version of Ant-Man's Suit, which Chris put on and promptly activated, shrinking down. Chris was killed, and Eric took Ant-Man's Suit off his body. Agent Mitch Carson was tasked with hunting down the person who had stolen the suit and given a less advanced prototype to aid him in his search.
Wasp's body was transformed into a living Pym Particle explosion. In the infinite void of Underspace, her new form can continue to expand the same way the universe expands, while the Infinite Avengers Mansion acted in a way to keep her form stable without dissipating. The ten billion Jocasta's Pym created performed similarly to the ten billion neurons in the human body - reinforcing Janet's brain wave pattern.
When Augustine Cross forced Dr. Sondheim to revive his father via a heart transplant from Cassie Lang, the surgery had the unexpected side-effect of granting Darren Cross the size altering abilities associated with the Pym Particles. However, Darren was unfamiliar with their use resulting in the powers being an obstacle rather than a boon.
Franklin Nelson was diagnosed with Ewing's Sarcoma, a type of cancer which formed in his hip. As chemotherapy was extremely expensive and painful, with the help of Hank Pym and his Pym Particles, Foggy began treating his tumor more directly.
Todd Ziller was a volunteer in the new Super-Soldier process. They could not recreate the serum so used existing transformative substances. The final result included Gamma enhancements, Mutant Growth Hormone, Pym Particles and the Connors Formula. The resulting application of the serum in Ziller's body turned him into a giant reptile similar to Godzilla, for which he was given the alias of "American Kaiju."
- Size Addition: Through acquisition of mass from the Kosmos Dimension, Pym Particles allow their users to grow to massive sizes, including hundreds of feet in height. This leads to a great increase in strength and durability. However, the larger someone grows, the more strength that is required to hold up the person's heavy body up. This can put enormous strain on the person's body.
- Size Reduction: Through mass extensions into an extradimensional space, Pym Particles users can shrink down to very small sizes. Because they don't lose any mass, users retains their level of strength while at normal height.
- Enter Other Planes of Existence: Pym Particles allow users to shrink to sub-microscopic stature. When 99.99 + % of a user's mass is extra-dimensionally shunted, he or she will be sent into a "subatomic universe" or "microverse," one of countless alternate universes accessible to Earth only by the mass-shunting process. The reverse can also be done and the Overspace can be entered if a user grow large enough.
|On Earth-199999, Dr. Hank Pym discovered and isolated a rare group of subatomic particles which he dubbed "Pym Particles". These particles allows for subjects to reduce the distance between their atoms thereby decreasing their size and increasing their density. He created Ant-Man's Suit that allowed him to regulate the particles use allowing him to shrink in size. Along with Janet van Dyne, his wife, in Wasp's Suit, Pym executed several covert missions for S.H.I.E.L.D. During one mission, Janet sacrificed herself to prevent a missile aimed for the United States from reaching its target resulting in her being trapped inside the subatomic void called the Quantum Realm. After this Pym abandoned the project and hid Ant-Man's Suit. However, after several years, Pym's former protégé Dr. Darren Cross was finally able to recreate the formula for Pym Particles and used them to create a weaponized suit called the Yellowjacket. This discovery forced Pym to come out of retirement and recruit a new Ant-Man Scott Lang in a mission to steal back his technology from Cross.||Ant-Man (film)Pym Particles are color coordinated so blue makes anything grow while red makes anything shrink.|
|On Earth-12041, Pym Particles are color coordinated so blue makes anything shrink while red makes anything grow.||Marvel's Avengers Assemble Season 1 23|
|On Earth-8096, like on Earth-616, Dr. Hank Pym discovered the Pym Particle. He used Ant-Man's Suit to harness the special particles to grow like a giant or shrink like an ant. He also injected Janet van Dyne with the particles that shrunk her to the size of a wasp and gave her stingers naming herself The Wasp. The Big House, Ultron guards, and the supervillain prisoners are the examples of the effects of Pym Particles which they were shrunk into a size of an ant while the building is shrunk into a size of a doll house. When Ant-Man's Suit was stolen by Scott Lang he used Pym Particles to steal money with Pym Discs but they were unsuccessful. After settling the issue and getting his daughter back Hank allowed him to continue being Ant-Man.||Avengers: Earth's Mightiest Heroes (Animated Series)|
|On Earth-12101, Deadpool stole Pym Particles from Henry Pym's lab before killing him, and used them to destroy the Avengers' headquarters and kill all the Avengers present, who were having a meeting on how to deal with him. Luke Cage and Thor survived however, but Deadpool revealed that he had planted miniaturized bombs in Cage's coffee to bypass his unbreakable skin, which he then detonated. When fighting Thor, he used Pym's technology to enlarge Mjolnir, which was in the process of returning to Thor, causing the now massive Asgardian hammer to crush its owner.||Deadpool Kills the Marvel Universe #2|
|On Earth-135263, one of Reed's Microverse experiments with Pym Particles caused the Fantastic Four to shrink, putting them at risk when H.E.R.B.I.E. mistook them for vermin and tried to exterminate them. The Fantastic Four were restored to normal size with Ant-Man's help.||Fantastic Four: World's Greatest Heroes Season 1 6|
