Rare group of subatomic particles which could increase or decrease the size and mass of objects or living beings originally discovered by Dr. Henry Pym.


Dr. Henry Pym originally discovered and isolated a rare group of subatomic particles, which have become known as the "Pym Particles", which could increase or decrease the size and mass of objects or living beings. The Pym Particles work by stunting matter into the Kosmos Dimension when shrinking an subject or accruing extra matter from that dimension when enlarging.

Originally, 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 the Ant-Man Suit to allow him to control his size.

Repeated Exposure

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.
