This band of young heroes first appeared on a morale boosting mission to the United States in 1942. They were inadvertently involved in one of the All-Stars' cases when Axis Amerika attempted to steal plutonium from Albert Einstein and his colleagues in St. Louis. (Young All-Stars #22-26)
Each member hailed from a country allied with the U.S. during World War II:
Fireball (Sonya Chuikov) was from Russia. She was born to a pair of Soviet scientists in 1922. In 1908, they had investigated the mysterious Tunguska fireball that struck central Siberia, and apparently their exposure to its aftermath had a mutagenic effect on Sonya. Soon after she was born, her wrists burst into a cool, non-burning flame. the flame could heat up and cover her entire body at times when she became angry or upset. As she grew, she learned to control the fire, being able to hurl firebolts and fly for short distances. Josef Stalin made her a ward of the state, and she was drawn into the War when her village was attacked by Nazi planes. Her family was killed and she almost died herself, from wounds she received while destroying some of the planes.
Kuei (real name unrevealed) was a Chinese hero born in 1922, in Shanghai. He learned English at university and then became a soldier. When his entire regiment was slaughtered by enemy troops, he was injured so severely that he threw himself into a nearby river to escape the pain by drowning himself. As he was dying, he saw a Japanese soldier peering down from the edge of the water, and he instinctively reached out to save himself. He grasped the soldier with the hand of a demon, and killed him. He had become a "kuei," which was, according to Chinese legend, the soul of someone who drowned or tried to commit suicide and cannot attain a further incarnation. Such a person would instead walk the Earth as a powerful and dangerous spirit.
Phantasmo (Jean-Marc de Villars) was a Frenchman descended from an earth elemental and a human man. He could pass through solid objects and was immune to objects like common metals, which come from the earth. Though he has not appeared since 1942, his postwar activities have been hinted at (Teen Titans Spotlight #11). NOTE: This character was Thomas' homage to writers Randy and Jean-Marc Lofficier. "De Villars" is the name of a Catholic priest, the author of Comte de Gabalis.
The Squire (Percy Sheldrake) was the English apprentice of the Shining Knight. After the War, Sheldrake took the code name of The Knight, and his son Cyril became the second Squire. In the 1950s, he was among the founders of the Dome. (Infinity, Inc. #34) Percy was ultimately killed by his arch-enemy, Springheeled Jack. Cyril succeeded him afterward, as the Knight II, but it's been mentioned that he too spent some time in a coma, perhaps from the same attack. The Knight shares a camaraderie with Batman; he is referred to as the "English Batman" and his helmet is modeled after Batman's cowl. The new Squire (III) is Beryl Hutchinson, a young girl talented with all forms of communication. (JLA #26)
Kuei's monstrous appearance led American police to attack him as he deplaned at their first War Bond Rally. Luckily, the Young All-Stars were on hand to calm things down. The young heores were unable to stop Axis Amerika's Kamikaze and Sea Wolf from kidnapping three scientists (including Werner Heisenberg) from Le Conte University.
Meanwhile, Fireball accompanied Iron Munro to New York City's Columbia University, where they were attacked by Übermensch and Gudra. She was left for dead but returned to the All-Star Squadron's Perisphere for help. She and the Atom set out to rescue Munro and some scientists from a hidden laboratory in Kansas. There, the scientists had been put by Baron Blitzkrieg into a strange apparatus that would harness their intellects and detonate a plutonium device. With much effort, the Young All-Stars and Allies managed to drive off Axis Amerika, free the scientists, and avert disaster.
The War Bond Drive was cancelled after those events, and the Allies returned to her homelands.
The Squire was the only hero to be featured in any capacity after this story.
