When Attuma Strikes!
Hank Pym is in his lab building a giant robot ant for research when he snaps at Janet van Dyne for dropping some equipment. Jan decides she’s had enough of Pym’s temperament and decides to leave him for good and go on holiday. When Hank finds her note he’s so shocked that he involuntarily grows to giant size, breaks through the roof of his lab and get electrocuted by some cables. The electrocution knocks him out and he returns to normal size. Elsewhere Jan’s plane flies over a strange fountain of bubbles in the ocean and the pilot notices an island that wasn’t there before. The island is in fact a cover for Attuma’s enormous undersea vessel and upon seeing the plane the barbarian decides to capture the passengers for studying human weaknesses to aid his conquest of the surface world. The plane is trapped in the bubbles that become denser than steel and force it to land. A giant Robotron informs the passengers they won’t be hurt if they follow orders and commands Janet van Dyne to enter it. The pilot intercedes and demands to speak to whoever is in charge however both he and his co-pilot are attacked with a paralysing ray. At the same time Janet, who in anger had left her costume and Wasp’s Sting behind, finds a few remaining crumbs of a shrinking pill. The crumbs aren’t potent enough to turn her into The Wasp but she manages to cybernetically communicate with some ants and commands them to find Giant Man.
Back in his lab, Hank has recovered consciousness and receives Jan’s distress message from the flying ant and swiftly changes to Ant Man. He then boards his miniature Converti-Car and follows the messenger to Attuma’s ship. On reaching the ship Pym grows to his maximum 50 feet height and dispatches two guards. Giant Man finds Janet inside and tosses her The Wasp’s gear but she’s unable to move due to a paralysing ray which Giant Man then destroys. Attuma proposes a bargain and tells Giant Man if he helps defeat the surface world he can become one of Attuma’s warlords. Pym refuses and is about to be ambushed from behind when The Wasp stings the approaching guard. Giant Man decides to use shock tactics and suddenly shrinks down to ant size. This confuses and terrifies Attuma’s hordes who think they’re dealing with a demon. Simultaneously The Wasp attacks her former captors with a number of stings before being shot by another paralysing ray. As the heroine falls, Pym shoots back to giant size and catches her. Frightened, Attuma and his men run out of the room, seal the door behind them and start flooding the chamber. Both Avengers shrink down to insect size and manage to survive in an air bubble until the chamber is drained. Then instantly Pym again becomes Giant Man and seeing this, Attuma believes all surface dwellers to be invincible and begs for mercy. The Warlord promises never to return to the surface and heads back to the depths with his army. Janet tells Hank the other passengers have already been freed and the two leave together in the Converti-Car.
The Horde of Humanoids!
