Multi-millionaire media mogul, private landowner, and serial manipulator of politics Charles Foster Kane had experimented with having a 'League' of sorts in 1925, which according to record ended disastrously for the three poor 'Science Heroes' he had employed. In 1938, the more elderly Kane, who was suffering from failing health and what modern doctors would have diagnosed as the early stages of depression, along with a deteriorating business empire, decided to form a more formal League, this time modelled specifically on the 1898 Murray League, which the ageing tycoon viewed as the most successful incarnation of the team due to their incredible defeat of the first Martian Invasion. Kane hoped to use his recreation of that League to intervene world events as his publications had once been able to.

Kane sent his star reporter, the daredevil journalist Jane Arden, to assemble the private team. Arden procured the following personalities to join Kane's menagerie:

- Gene Autry, the strikingly handsome balladeer and latter-day gunslinger from Texas had been on a variety of notable adventures during the pre-war decade, most notably to the underground outpost of Murania. Autry had grown frustrated by the time he had been recruited as Kane's Allan Quatermain analogue, as his older brother, Orvon, had become vastly more famous through the countless songs, films and serials he starred in stolen from the life and works of his arguably more talented sibling. Autry agreed to join the League after Kane's offer of a film contract at Mammoth Studios, where the millionaire had a large share.

- Ann Darrow, the young actress who famously became a prisoner of the colossal simian cadaver who terrorized New York City in 1933. Darrow's survival physically, and maturation and courage gained from the incident mentally lent Darrow a Mina Murray quality which appealed to Kane. Much like Murray, the opinionated Darrow had recently divorced husband Jack Driscoll, whom she had been feeling socially restrained by. This more cynical, strong-willed version of Darrow than the one the Ape-monster had captured was certainly no longer a damsel in distress.

- Tom Powers, the former Chicago crime boss, and enemy of the Third American League, Powers had faked his death in 1931 while escaping from the so-called 'Burns Mob' and suffering from debilitating injuries. Powers had promised the family of a deceased friend of his to reform himself, and promptly took upon the identity of 'Thomas Masters', and relocating to New York City to become a Fireman. Arden tracked down Powers and offered him the 'Invisible Man' position in Kane's new League. Although initially reluctant, and confused why such a role would belong to himself, Powers accepted on the grounds Kane's influence would help cover up his criminal past for good. Kane then delivered to Powers a wearable device invented by Kane-sponsored Dr. Stanley Stanfield that would grant him invisibility, barring his shadow.

- Armand Robur, the French Aeronaut, son of the legendary 'Conqueror of the Skies' Jean Robur, notably married Nemo family heiress Hira Dakkar the same year as he served in this League. Robur served fittingly as the Captain Nemo surrogate in Kane's League, with his colossal airship The Terror serving as an equivalent to The Nautilus. As compensation for his service, Kane promised Robur to stir anti-fascist sentiment within his newspapers to subtly convince the American people to come to the aid of the French should war break out in Europe.

- William 'Bill' Dunn, in 1933 this Depression-stricken vagrant briefly became an enormously powerful telepath after participating in the experiments of another Kane-funded scientist, Professor Ernest Smalley. During this period Dunn became mad with power, christening himself 'Superman' and attempting to conquer the Earth. These powers wore off, after a time however, leaving Dunn as he was beforehand, his mind sane again. This changed in 1935, when the drifter found himself afflicted with a duel personality much like Henry Jekyll/Edward Hyde in the 19th century, with his powers returning for a megalomaniacal and darker alternate personality which surfaced in Dunn's stress. Kane found the obvious place for Dunn as his Jekyll/Hyde allegory, but not under his old 'Superman' title, as earlier in 1938, another quite recognisable individual had taken that moniker.

After Kane and Arden had compiled this League, the decrepit tycoon had the group gather at his vast, but incomplete Florida estate of Xanadu, where he gave them instructions toward what would be their first, and consequently only assignment.

After the 'Skull Island' incident Ms. Darrow had been involved with, Kane had become heavily interested in the idea of capturing similar primordial beasts as the brutish creature, which had kidnapped the former Mrs. Driscoll five years earlier. In order to accomplish the procuring of a similar animal as the 'Kong' creature, the Media Mogul instructed Robur to transport the League via The Terror to the Indian Ocean situated British colony of St. Georges Island, where Armand would leave the craft with his subordinates for the safety of the air vessel. At this point, the team would take the steam ship Venture II to the Skull Archipelago (the actual Skull Island had been submerged after a large volcanic eruption in 1934), and make landfall at Farou Island. On Farou the League would search to see whether this island contained creatures similar to it's sunken sibling [Note: Kane was unaware of The Third American League's prior expedition to the island at this point].

Despite some reservations on the behalf of Powers and Robur over the necessity of such an expedition, and trepidation from Darrow, who was naturally reluctant to return to such a location, the expedition went ahead, arriving the League at Farou Island in the August of 1938. The League disembarked from Venture II onto the Sinbad-chronicled isle on via raft to an unoccupied beach, before making their way inland through the dense jungle.

After setting up camp for the night, Dunn began to feel the brain activity of a large number of people originating from somewhere within the island, so the team Powers search ahead with his invisibility for any signs of habitation.

While Powers was gone, Darrow pointed out what appeared to be miscellaneous animal noises in the distance, but she interpreted specifically as the noises of an Ape like creature similar to the one she had encountered five years earlier. The proactive Robur deuced that if the sounds of such a creature as Ann had mentioned could travel over the distance the League could hear it over, it must be at least the size of the beast which had kidnapped the actress, and planned to go out after the sound of the bestial moaning as soon as their Invisible Man returned.

As it occurred however, the sounds became louder and more disturbing, as this creature began to appear in some sort of pain. This prompted the ever-ethical Autry to volunteer to track down and put down the creature, should it be in grievously wounded. Robur was concerned that Autry's absence would limit the group's numbers to greatly, as Powers had still not returned from his scouting mission, but the balladeer convinced the aeronaut that he would search for their missing comrade while out, and left promptly with his hunting rifle.

Robur, Darrow and Dunn remained at the camp in wait of their two allies, the latter two enjoying each other's stories of a similar experience in Depression-era struggles.

At about midnight, a brilliant red flare was let out over the tropical forest. Robur identified this as one belonging to Autry's emergency flare-gun, and immediately ordered Dunn to follow him as he traced the signal. Darrow demanded she go as well, accusing the aeronaut of sexism, but Robur left her to guard the camp as he and the schizophrenic 'Superman' ran on ahead.

Robur and Dunn found Autry in a far-off clearing, where the gunslinger had been detained in a matinee-esque wooden cage. The Midwestern hero had been captured by a joint team of German and Italian military, identifiable by their uniforms. The fascists had locked down their area and set themselves up in a small camp, set around another prisoner of theirs, held in an even larger wooden cage. This second captive was the enormous ape-creature, which had been letting out the colossal moans, and was currently being hooked up to a number of chords and wires, pumping strange fluids and electrical energy into the drugged beast's body.

The sky captain and the telepath were immediately surrounded and captured by the grey-uniformed; MP40 carrying soldiers, and took the logical decision of surrendering to them.

Dunn was convinced that these troops had been the source of the mental activity he had detected, and was able to read lightly into their minds to uncover that his captors had arrived here via U-Boat from the Italian territory of Wadiya in East Africa.

The two German leaders, the future Nazi-League member Dr. Wichserkopf Merkwürdigliebe, and Tank Commander Hugo von der Drache, interrogated Robur and Dunn, before explaining to them their plan for the Ape. According to the two loyal fascists, the Axis had planned to create an army of Dinosaurs and the other extinct creatures that inhabited the Skull Archipelago, but to quadruple their power before hand. This particular poor simian that had been captured by the European madmen was being injected with both a super serum that would greatly increase his size, and a metagene that would allow the animal to channel unnatural amounts of electricity through his body, shocking his enemies to death.

Robur assured his wardens that their plan was insane, but his words only ended himself and his compatriot Dunn before a makeshift firing squad, to ensure to two Kane employees wouldn't give away the insidious plan to the Americans or the French.

Conveniently, the near fatalities of Robur and Dunn were averted when the central tent of the German-Italian encampment was exploded by a bazooka, throwing a group of soldiers across the campsite, and sending the rest of the soldiers into frenzy.

The two Kane-ites made a break for it, Robur reclaiming his weapons and gunning down the Nazis who attempted to block his escape. Dunn assisted his comrade by freeing Autry, and using his telepathy to throw the enemy gunmen off target, hitting each other instead.

The mysterious, projectile firing saviour of the two heroes emerged from the jungle, revealing herself as Darrow, using Robur's handheld artillery from their own camp.

At the same time, a tribe of natives from elsewhere on the island besieged the fascist camp, led by Powers, who had been impersonating their 'Shadow God' with his partial invisibility, and had collected their aid as such.

This nearly assured victory for the Kane League was rudely interrupted when a pack of Velociraptors, drawn by the commotion, ambushed the two sides, tearing poor Darrow, Dunn, and many of the natives, limb from limb.

The disgusted and disturbed survivors; Robur, Autry and Powers, had no time to waste despite their horror, and made a break for the shore, where they intended to signal the Venture II. However, the three men could not outrun the sheer speed of the Raptors, and the Invisible Powers abruptly decided to draw the monsters away from his friends. The former criminal may have been invisible to the dinosaurs, but his scent was enough to attract them. As Powers drew the Raptors off into the deep jungle, the terrified Robur and Autry heard their friend's screams echo across the island.

When the surviving teammates reached the beach, they waited impatiently as the Venture II sent out its sailors to rescue them. The raft finally arrived, but the Raptors arrived at the same time, rushing towards the Men, prepared for the kill. Just as suddenly, the Ape creature from the campsite burst through the trees onto the sand, having spontaneously grown since escaping his capture during the earlier chaos. The Gorilla monster tussled with the Dinosaurs, electrocuting one, which frightened the rest of the pack enough to force them into tactical retreat.

In this time, Robur and Autry had gotten aboard the raft and been rowed halfway to the steamship, but as the disturbed adventurers were escorted to safety, they made eye contact with the Ape creature still on shore, which gazed back at them bitterly, while the beast's body continued to leak of the Nazi derived fluids.

When the thoroughly scarred heroes arrived back at Xanadu in Florida, they learnt that the two Axis leaders from the island had been captured by the natives before the Wadiyan Navy rescued the two.

Kane was unimpressed by the failure of the mission, and dismissed the two Men, with Kane cancelling his promise of to Autry of a film contract. Naturally both Robur and Autry were furious, and left Xanadu absolutely embittered. Robur went on to distract himself from the his trauma by happily marrying Hira Nemo, and Autry became an explorer, venturing to the North Pole, where he found solace and refuge in the kingdom of Queen Olympia, chronicling the life of the so called 'Shaman of the North' in a number of festive songs which he sold to Orvon for a sum that allowed him to retire.

This League may have been an unmitigated disaster, but it may have actually helped the Allied cause in World War II in the long run, as they prevented the Axis Powers from developing their primeval army they had hoped for.

Charles Foster Kane died a lonely man in 1941, causing a media frenzy after the ambiguous uttering of his last word.
