The Incredible Shrinking Doom! The Beginning! Hank Pym and Peter Parker are working in Pym's lab when a gangster steps in and tells them to warn Dr. Curt Connors that he and his crew have kidnapped Connors' son, and they want the new drug that Doctor Connors has been working on. Pym doesn't know Parker's identity as Spider-Man, but Hank's identity is public, so they go off to stop the kidnappers and retrieve Connors' son. They can't tell Connors because stress will turn him into the Lizard.
They confront the criminals, but their leader produces the kidnapped boy and explains that he's been infected with a fatal virus and that Ant-Man and Parker (Peter doesn't put on his costume for this fight) will stop, or he will not give the antidote to the boy.
The boy escapes, and Ant-Man demands that he be allowed to rescue him, but the kidnappers tell Ant-Man that they won't let him go unless he and Parker allow themselves to be injected with the drug first. Allowing it, Ant-Man and his dog, Orkie, go off to find the boy, but on the way, he discovers that he cannot grow to his full height again once he's shrunk to just above ant-size. Tied up in the next room, Parker escapes, changes into his Spider-Man garb, defeats the kidnappers and retrieves the drugs. The duo and the boy are cured, but Ant-Man has discovered that he cannot grow to full size.
