History: When World War I ended the original Union Jack was officially retired from active service by the British Government. Lord Montgomery Falsworth eventually married, had two children, Brian and Jacqueline, and came to lead the life of a peaceful country squire.

In 1938 Lord Falsworth was outraged at British Prime Minister Neville Chamberlin's policy of appeasement towards Adolph Hitler's German regime. Falsworth's son Brian, however, was an isolationist and pacifist and disagreed with Lord Falsworth's views. The arguments between the two grew more heated as time passed, until finally Brian left home because of them. Shortly afterwards, the Germans released photographs showing Brian Falsworth and his best friend Roger Aubrey with Hitler himself; both Brian and Aubrey publicly supported appeasement of Hitler's regime while they were in Germany.

Lord Falsworth was appalled and saddened by this development. War between Britain and Germany broke out, and his wife, Lady Falsworth, died in the Blitz of 1941, when a German bomb fell on a London hospital where she was doing volunteer work.

Early in World War II Brian Falsworth and Roger Aubrey tried to leave Germany. The Nazi government was unwilling to risk the possibility that Falsworth and Aubrey would reverse their anti-war positions, and a Gestapo chief in Hamburg, Germany tore up their passports. Falsworth lost his temper and attacked the Gestapo chief, only to be imprisoned. Aubrey then became violent and was likewise made a prisoner, but he was finally turned over to the Institute of Nazi Science, where he was brainwashed and subjected to experiments that transformed him into Dyna-Mite, a man less than a foot tall.

Brian Falsworth was imprisoned in Hamburg in the same cell as the German biochemist Eric Schmitt, who had concocted a variant of the Super-Soldier formula that was used to turn Steve Rogers into Captain America. Dying, Schmitt asked Falsworth to keep the sample of the formula he had concealed on his person from falling into Nazi hands. Falsworth took the disguised flask, drank its contents, and was immediately physically enhanced by the formula. Falsworth escaped the prison and became a costumed fighter of Nazis within Germany itself known as the Mighty Destroyer.

In England in 1942, Lord Falsworth and his daughter Jacqueline befriended the Invaders, a team of costumed champions serving the Allied cause much as Freedom's Five had done during World War I. Lord Falsworth again donned the costume of Union Jack in order to help the Invaders battle the returned Baron Blood, and was made an Invader himself. However, in a battle between Union Jack and Baron Blood in a cave beneath the Falsworth estate, the vampire hurled a massive boulder at Union Jack, crushing his legs and leaving him permanently crippled. Union Jack managed to pry the boulder off his legs, and then the huge rock struck Baron Blood, knocking him backwards. The vampire fell onto sharp stalagmites, which impaled his body, killing him.

Lord Falsworth's career as Union Jack was over, but as a result of being bitten by Baron Blood and then receiving a blood transfusion from the original Human Torch, an android, Falsworth's daughter Jacqueline became the superhumanly powerful Spitfire and joined the Invaders herself.

Lord Falsworth, Spitfire, and Dyna-Mite parachuted into Nazi Germany in the hope of finding a means of restoring the brainwashed Dyna-Mite's memory. Lord Falsworth knew that Dyna-Mite was Roger Aubrey and hoped that once Aubrey's memory was restored, he could reveal what happened to Brian Falsworth. Lord Falsworth and Dyna-Mite were captured by the Germans but were rescued by the Mighty Destroyer, who revealed his true identity to his father and was reconciled with him. Lord Falsworth suggested that Brian adopt the costume and name of Union Jack, and Brian agreed.

Meanwhile, Spitfire and her fellow Invaders had been captured by the Germans and were to be executed by a firing squad under the command of Hitler himself. Brian Falsworth, as the second Union Jack, came to the Invaders' rescue, and the Invaders, Lord Falsworth, Dyna-Mite, and the new Union Jack all escaped back to Britain. There a captured Nazi scientist restored Aubrey to his true height. Aubrey, whose memory had finally fully returned, adopted Brian Falsworth's previous identity of the Mighty Destroyer and returned to Germany to continue battling the Nazis there. Brian Falsworth, as the new Union Jack, became a member of the Invaders.

Later, Hitler succeeded in contacting the Asgardian thunder god Thor and deceived him into aiding the cause of the Germans, the descendants of the people who had once worshipped him, in the current war. Thor therefore clashed with the Invaders and nearly killed the second Union Jack with a blast of lightning from his enchanted hammer. Learning that Hitler was evil, Thor vowed to aid him no more, and withdrew most of the electricity in Union Jack's body back into his hammer, somehow restoring him to health in the process. The second Union Jack now possessed the superhuman power to discharge electrical bolts from his body. It is not known how long Union Jack retained this power,

The second Union Jack was still a member of the Invaders when World War II ended on the European front. Brian Falsworth died in an automobile accident in 1953.

Lord Falsworth hoped that Jacqueline's son Kenneth Crichton would become the third Union Jack, but Kenneth did not wish to do so.

In then years the now extremely elderly Lord Falsworth suspected that a series of "slasher" murders in the vicinity of Falsworth Manor were the work of a secretly resurrected Baron Blood, whom he now knew to be his brother John. Lord Falsworth summoned his former Invader colleague Captain America to England to stop the vampire. Lord Falsworth's suspicions proved to be correct, and he desperately wished he could become Union Jack again in order to end his brother's evil forever. Finally, Lord Falsworth donned his Union Jack costume again, planning to serve as bait to lure his vengeance-seeking brother out of hiding so that Captain America could defeat him. Lord Falsworth then suffered a heart attack, but Captain America carried forth his basic plan, with Kenneth Crichton's friend Joseph Chapman disguised in the Union Jack costume. Chapman, as Union Jack, battled Baron Blood, but it was Captain America who finally slew the vampire by beheading him, thereby ending his vampiric life permanently.

Lord Falsworth died quietly while watching the burning of Baron Blood's remains, knowing that his brother's evil had been overcome at last. Joseph Chapman has continued to operate as the third Union Jack, carrying on the noble tradition of both Montgomery and Brian Falsworth.
