The Fighting Yank #21

In the steamy jungles of the Belgian Congo, a luxury passenger plane carrying Bruce Carter III and his companion Joan crashes into a hidden underground cavern—only to discover it's the secret lair of the sinister Dr. J.J. Dulfer and his band of rogue scientists. Bound and helpless, Bruce must transform into the Fighting Yank to battle Dulfer's horrifying creations: gorillas enhanced with human gland extracts, engineered to obey their master's every command. As the Yank fights to free his fellow passengers and escape the cavern's deadly traps, Dulfer himself closes in with a plan to reclaim what he's lost—and finish what he started.

When Bruce Carter III—the Fighting Yank—visits Moldman's Waxworks museum to investigate a mysterious crime wave, he discovers a ruthless gambler's plot to drive the elderly owner mad and seize the property for a casino. As murders attributed to the wax figures multiply, the Yank must uncover the truth behind the disappearing dummies and stop the scheme before it's too late. With a nervous curator under arrest and danger closing in, only the Fighting Yank can expose the criminals masquerading as the museum's most sinister exhibits.

When a scientific expedition backed by Bruce Carter III uncovers a massive gold urn in the Yucatan jungle, the expedition's leader Professor Marston reveals his true colors—willing to kill for the treasure hidden in the mountain. As Bruce transforms into the Fighting Yank to stop the murderous archaeologist, the mechanical mole burrows into a shocking discovery: a hidden valley containing a lost Mayan civilization, complete with warriors, temples, and ancient secrets. Now the Yank must navigate treacherous Mayan guardians, deadly traps, and Marston's ruthless ambitions to protect his companions and uncover what lies within the House of Chac-Mol.
