Tales to Astonish #54 (1964)

Watching the Huntley-Brinkley Report, Giant-Man learns that the nation of Santo Rico has just elected El Toro as their new president. The report notes that, even though the nation of Santo Rico is a democratic nation, the communist-backed El Toro won by a landslide. Giant-Man is interrupted by the Wasp, who demands that they plan a vacation, to which Giant-Man declines because he's far too busy. Wasp provokes a brief tussle between the two, so that Giant-Man will get so mixed-up that the next time she suggests a vacation he'll agree before he knows what he's doing. Soon afterwards, the two heroes are bombarded by a surprise visit by their fan club. After hosting them for a brief period, they get a phone call from Washington, D.C. asking them for assistance, and Giant-Man shoos his fan club out of his lab. They elude their insistent fans by shrinking down to ant size to leave the premises. In Washington a few hours later, government representatives ask them to go to Santo Rico to find proof that El Toro rigged the election. Accepting the mission, the two heroes travel to Santo Rico in their civilian guises of Henry Pym and Janet Van Dyne. Arriving there, Pym trusts Janet with the size-changing capsules. Noticing the armed troops everywhere, the pair realize that the country now looks like a real police state. As they arrive at their hotel, they are noticed by a member of the secret police who thinks they look suspicious and reports them to El Toro who, figuring them to be American spies, orders them to be seized. When the soldiers come to arrest the two heroes, they grab Janet first, but not before she can toss Henry a growth capsule. After racing around a nearby building, Henry drops his outer clothing and swallows the capsule to become Giant-Man who then tries to rescue Janet. However, his attempt is thwarted when he is rammed from behind and knocked down by El Toro himself. Struggling to his feet, Giant-Man vows to rescue Janet, but finds himself an easy target when El Toro orders his death and he is stuck at giant size. Smashing through the city to get away from guards, Giant-Man escapes by following railroad tracks to open country, but when an oncoming train forces him to jump aboard in order to avoid being hit, Giant-Man finds it taking him back to the capital city. Fortunately, by this time night is falling, giving Giant-Man hope that he can find a hiding place. Later, using the darkness as cover, Giant-Man retrieves his cybernetic communicator and uses it to create a network of ants who are all commanded to locate the Wasp. When one finally finds her on a ship anchored off the coast, "Ant-Man" is alerted and, just before dawn breaks, Giant-Man uses speed boats as water skis in order to reach the ship and rescue Janet. Regaining the size capsules and freeing the Wasp, the two heroes shrink to ant-size and hitch a ride on Janet's guards as they go to El Toro to report her escape. Arriving in El Toro's office, Giant-Man and Wasp let their presence be known, and El Toro attacks them. Giant-Man easily defeats El Toro who ends up hanging helplessly from a flagpole above the city square while the Wasp finds documents proving that the election was rigged by communist backers. Giant-Man tosses the papers down to the crowd of onlookers who are enraged to learn that El Toro cheated them because he won the election using votes that had been bought and paid for by the Reds. The crowd denounces El Toro as a tyrant and a traitor, and depose him, vowing to hold a new election. Two days later, after returning to America, Giant-Man and the Wasp are congratulated for freeing Santo Rico from communist tyranny. Later, Giant-Man states that he's had enough traveling around to last him for years, but the Wasp is still trying to decide where they should go for their vacation.
