Pym Particles (Earth-6531)

"Moscow proves there's important work to be done in the field that only the Particle can handle. And I told you before, the only way S.H.I.E.L.D. gets a Pym Particle is with a Pym operating it."

- - Doctor Hank Pym to Howard Stark

Pym Particles are subatomic particles discovered by Doctor Hank Pym capable of shrinking a human to the size of an insect, while severely enhancing their strength.

History
Discovered by Doctor Hank Pym in 1961, the Pym Particles are of extra dimensional proportions, with Pym quickly discovering he would be able to increase or decease the mass of objects, and even organisms, to a subatomic dimension he named the Quantum Realm. Alongside his wife, Janet van Dyne, the couple would use this discovery as field agents for S.H.I.E.L.D. - he as Ant-Man and she as the Wasp.
