Marvel Comics has a rich history dating back to World War II, but unlike DC, they never actually had a superteam back at the time of the war. Sure, Captain America, Bucky, Human Torch, Toro, Namor, and others would work together, but there would be no official team back in the 40s.
That changed in 1969, when the Invaders were introduced. A retcon that made those unofficial partnerships into a team, gathering together Marvel's WWII heroes and chronicling their adventures. While not as popular as DC's Justice Society of America, they would still boast some powerful members and this list sets out to rank them.
10 Bucky
James "Bucky" Barnes was Captain America's sidekick. He was a skilled fighter and it would later be revealed that he did a lot of the dirty work that Cap himself wouldn't do, sneaking behind enemy lines and carrying out commando missions. This never dampened his youthful spirit or cheerful demeanor.
That said, he was very young and a completely normal human with no enhancements. He was good with weapons, but calling him powerful would be a mistake. He definitely had his place with the team, though, and served his role admirably. Later, he would become the Winter Soldier, gaining a robotic arm and clashing with Captain America before coming back to the heroic side.
9 Silver Scorpion
Betty Barstow was a secretary who foiled a robbery at a costume party and became the superheroine Silver Scorpion. She would fight against the Axis powers on the homefront and would eventually be made into an honorary member of the Invaders.
She was one of many costumed vigilantes of her time that had no powers, using her fists to fight crime and the Axis. In a battle with Battle-Axis, she would be injured and go on to don a suit of armor that fired a "scorpion sting" from wrist mounted blasters. She would eventually abandon the armor and continue the fight against the crime after the war.
8 Union Jack
Lord James Montgomery Falsworth was a British nobleman who served in both WWI and WWII as the costumed operative Union Jack. The British answer to Captain America, he would hold up British values and defend the land from the Germans, taking the fight to the enemy and joining the Invaders.
A seasoned soldier, Falsworth had no superpowers, but was a formidable combatant. He would even be able to take down the vampire, Baron Blood, saving a leading member of the British Parliament from the German allied monster. His son would take up the mantle later, keeping the legacy alive.
7 Captain America
Everyone knows Captain America's, origin story. A 98 pound weakling who wanted to fight the Axis, he was subjected to a government experiment and became the pinnacle of human development. Armed with an unbreakable shield, he would take the fight to the enemy, becoming a living legend.
While he's easily the greatest hero of WWII, powers wise, he doesn't stack up to other members of the team. Though, as an expert fighter, with vast physical strength and acrobatic ability, he would be able to more than hold his own. He would go on to the lead the Avengers and cement his legendary status.
6 Whizzer
While on an expedition to Cameroon with his father, Robert Frank was bitten by a cobra. His father would inject him with mongoose blood and the blood would interact with his mutant physiology, giving him superspeed. He would join the Invaders when a call was put out by Bucky to save other members of the team brainwashed by Red Skull.
His superspeed made him a formidable opponent. He would meet his wife Miss America on the team and they would go on post war adventures together. The two would be suspected to be the parents of Quicksilver and Scarlet Witch for years before various retcons would reveal it otherwise.
5 Spitfire
Union Jack's daughter, Lady Jacqueline Falsworth was abducted and bit by the vampire Baron Blood. Given an emergency blood transfusion from the android Human Torch, she would develop superspeed and vampiric superstrength and become Spitfire, joining the Invaders.
While the team had another speedster on it, it's her limited vampiric abilities that put her above Whizzer in the power department. Add to this vampiric regeneration and she would be a formidable member of the team, luckily never having to ingest blood to fuel her abilities.
4 Human Torch
Not to be confused with the Fantastic Four's Johnny Storm, Jim Hammond was an android created by Phineas Horton. He was one of the first Marvel Comics heroes, premiering in Marvel Comics #1. He, along with his sidekick Toro, would go on to join the Invaders and battle the Axis powers.
He would have wide fire based powers, being able to generate a nova flame blast, envelope his body is fiery plasma, and control flames. He also could fly and had thermokinesis, which allowed him to manipulate the ambient temperature of a room. These powers would serve the team well in their battles.
3 Blazing Skull
Mark Todd was a journalist covering the Second Sino Japanese War. During a Japanese attack, he would be saved by the Skull Men, a mysterious mystical sect. They would go on to train him, showing him how they tapped into their abilities and would become the superhero the Blazing Skull, going on to the join the Invaders.
These abilities would include superhuman strength, immunity to flame, a regenerative healing factor, flame generation and control, and eventually the ability to turn invisible. His look would go on to inspire the look of Ghost Rider, although the two heroes have no relation other than cool blazing skull heads.
2 Namor The Sub-Mariner
Namor McKenzie was the son of a human and an Atlantean. This would make him one of Marvel's first mutants. He would become the king of Atlantis and wage war against the surface world on multiple occasions, but during WWII, he would fight against the Axis powers, becoming a member of the Invaders.
Namor's powers include superstrength, super durability, super stamina and reflexes, flight, a telepathic link with sea creatures, and many other abilities. After the war, he would tangle with the Fantastic Four before becoming a member of the Avengers and the X-Men. Recently, he would tangle with the Avengers again, in another attempt to combat the surface world.
1 Vision
Vision, not to be confused with the android Vision who would go on to become a member of the Avengers, was an interdimensional being named Aarkus. A "Keeper Of Law" on his home plane of Smokeworld, he would eventually be drawn to Earth and fight crime, before getting embroiled in WWII and joining the Invaders.
While not a well known character, he had a variety of superpowers, including smoke control, teleportation, immunity to all toxins, the ability to manipulate gaseous matter, superstrength, super agility, super durability, flight, telepathy, cryokinesis, and the ability to manifest an astral form. This wide variety of powers made him the most powerful member of the team.
