Unconscious, Hulk is transferred by Psyklop to an underground lab where the ancient villain shrinks the Hulk with one of his devices to better study him. But Psyklop is interrupted by the Avengers: Captain America, Iron Man, Falcon, Thor, and Goliath!
Busy fighting the Avengers, Psyklop forgets about the Hulk who shrinks to sub-atomic size, reaching the microverse!
Hulk lands on a strange planet called K'ai, its dwellers are human-like but with green skin like the Hulk's. They greet Hulk as a hero after he defeats giant pig-dogs known as Warthos.
Hulk is taken to their queen Jarella, and wow, isn't she beautiful to Ol' Greenskin!
Jarella's wizards, Torla, Holi and Moli cast a spell that allows the Hulk to understand their language. As a side effect, Bruce Banner takes control over the Hulk's form.
Hulk and Jarella fall in love immediately. She even thinks she's found her "green" prince and prepares for the wedding. But that's not good for Lord Visis, her cousin who wants to marry Jarella to become king.
Lord Visis sends his men against the Hulk, but he defeats them easily, and denounces Lord Visis' treason publicly.
The multitude now acclaims the Hulk as their upcoming king!
Suddenly, Psyklop's giant hand appears, grabbing the Hulk, who feels incapable to fight back, and lets himself be pulled.
Jarella cries the departure of her beloved as Hulk is returned to Earth, to Psyklop's lab, where the green monster regains control over his own body. Hulk defeats the villain easily, and leaves.
Having failed his mission, the Dark Gods punish Psyklop.
