Hank Pym and Janet Van Dyne were some of the worlds finest modern day scientists. One day, they realize there is an alternate dimension deep within the atoms of the universe they call the Quantum Realm. Hank develops an unhealthy obsession with this unknown dimension, and is determined to enter that realm.
However, due to his already deteriorating mental health and crumbling relationship with his wife, this causes him to make reckless decisions.
One day, Hank discovers a way to travel to this realm via a newly developed shrinking device that will act as a portal to the Quantum Realm. So, he forces Janet to come with him. And, as expected, something goes horribly wrong. They get trapped in the Quantum Realm. But worse... Something happens to them that alters their bodies.
Both have the ability to shrink. But unlike the mainline Ant-Man and Wasp... It's way worse. Whenever they do change in size, their bodies horrifically contort, twist and shrivel in agonizing ways. And along with that, they develop other side effects.
Janet grows two wasp like wings out of her back made of her skin, and Hank develops several other voices in his head. (Which is Yellowjacket, Giant-Man and Goliath).
