Among Marvel’s vast array of characters, few exemplify friendliness quite like Captain America. While even friendly neighborhood heroes like Spider-Man can possess less-than-pleasant traits that challenge their reputations, Steve Rogers shines as a universally adored figure. It is indeed rare to encounter anyone who harbors dislike for Captain America; if such a notion exists, it’s often reserved for the villains of the Marvel universe.
The charm of Captain America lies in his open-hearted nature. He extends friendship and trust to almost anyone, provided they aren’t affiliated with the darker aspects of humanity—think swastikas, the Red Skull, or anyone resembling Hitler. This welcoming demeanor has enabled Captain America to form a diverse network of allies, whom he can rely on both emotionally and physically. Many of his most formidable comrades are among the strongest characters in Marvel’s storied comics history.
10 Sam Wilson
First Appearance: Captain America #117 by Stan Lee, Gene Colan, Joe Sinnott, and Sam Rosen
Sam Wilson, known as Steve Rogers’ best friend and the second to bear the Captain America mantle, stands out not only for his valor but also as the physically weakest link among Captain America’s allies. While highly capable and skilled, Sam lacks the Super Soldier Serum that grants Steve his superhuman capabilities. In fact, during a mind-controlled skirmish, Sam even fell short against Spider-Man—a testament to the limitations faced by a mere human.
This isn’t a critique of Sam’s abilities—it’s simply the reality of human limitations when stacked against individuals equipped with super-strength. Steve Rogers’ victories over Spider-Man in past encounters underscore the inherent advantages of the Super Serum, illustrating the stark difference between human and superhuman strength in battle.
9 Ian Rogers / Nomad
First Appearance: Captain America #1 by Rick Remender, John Romita Jr., Klaus Janson, Dean White, and Joe Caramagna
Ian Rogers, although not biologically linked to Steve, is one of the strongest allies related to the Captain. As a product of genetic manipulation, Ian possesses enhanced abilities, which he uses to aid his father in his quest against evil under the mantle of Nomad. While he may not rival Captain America’s strength, his enhanced durability and conditioning make him a formidable ally in his own right.
8 Bucky Barnes / The Revolution / The Winter Soldier
First Appearance: Captain America Comics #1 by Jack Kirby, Joe Simon, Al Liederman, and Howard Ferguson
Bucky Barnes, equipped with a Vibranium arm, displays an impressive strength level that makes him one of Captain America’s most potent allies. A notable demonstration of his power occurs in Laura Kinney: Wolverine #5, where he accurately lifts and hurls a character with Adamantium bones—a feat requiring significant strength.
While he may not be the strongest superhero overall, Bucky’s affiliation with Steve Rogers as a key ally firmly positions him among the ranks of powerful comrades.
7 John Steele
First Appearance: “Soldier of Fortune, John Steele”by Larry Antonette from Daring Mystery Comics #1
While Captain America is celebrated as the quintessential super-soldier, John Steele precedes him as America’s first super-soldier. Although John is human, his extraordinary feats of strength, such as lifting two tons, set him apart. Even Steve Rogers has recognized that Steele outmatches him in strength and speed, making him a highly valuable ally on any battlefield.
Steele’s legacy includes his wartime efforts against the Nazis, aligning closely with Captain America’s mission, and reinforcing the camaraderie between these two strong allies.
6 Shadow Soldier
First Appearance: Sam Wilson: Captain America #2 by Greg Pak, Evan Narcisse, Eder Messias, Fernando Sifuentes, and Joe Caramagna
Introducing Josiah X, also known as the Shadow Soldier, he holds a significant place in Captain America’s legacy, being the son of Isaiah Bradley. Isaiah himself is a landmark character who fought against unequal treatment in the Project Rebirth experiments. Josiah, enhancing his abilities through similar conditions, now possesses superhuman strength, speed, and agility. This formidable set of skills makes him an excellent partner for Sam Wilson’s Captain America.
5 Demolition Man
First Appearance: Captain America #328 by Mark Gruenwald, Paul Neary, Vince Colletta, Ken Feduniewicz, and Diana Albers
Though he may sport a costume reminiscent of Daredevil and Wolverine, Dennis Dunphy, known as Demolition Man, showcases super strength that solidifies his status as one of Captain America’s strongest allies. As Mark Gruenwald aptly noted, D-Man’s experience with Power Broker Inc’s super-strength treatments means he can lift several tons with ease, truly comparable to Captain America in strength.
The shared strength and camaraderie between Steve Rogers and Demolition Man create a balance of mutual respect in their partnership, allowing them to stand as equals in power.
4 Aarkus
First Appearance: “Enter: The Vision”by Jack Kirby and Joe Simon from Marvel Mystery Comics #13
Aarkus, also known as the Golden Age Vision, is a cherished ally of Captain America. First introduced in 1940, this extraterrestrial defender was a pivotal figure during World War II, fighting alongside heroes like Captain America and demonstrating powers that afford him Class 10-level strength. His long-standing friendship with Captain America is rooted in their shared battle against evil, establishing them as strong allies in each saga.
3 Destroyer / Keen Marlow
First Appearance: Mystic Comics #6 by Stan Lee and Jack Binder
The legacy of the Destroyer, originally Keen Marlow, is integral to Captain America’s story. After encountering a variant of the Super Soldier Serum, Marlow became one of Marvel’s most powerful super-soldiers. His capabilities, both in speed and strength, rival Captain America’s. Marlow’s shared experience with the Super Soldier Serum fosters a unique understanding and bond between himself and Captain America, highlighting their similarities as heroic figures.
2 Namor
First Appearance: “The Sub-Mariner”by Bill Everett from Marvel Comics #1
Namor, whether as a teammate in the Invaders or the Avengers, has developed a unique camaraderie with Captain America. Their deep mutual respect is built on a complex friendship that transcends their occasional differences. Steve listens to Namor as a peer and has frequently acknowledged his impressive strength and capabilities, which can even rival that of the Hulk. This solidifies Namor’s position as one of Captain America’s most powerful allies.
1 Superman
First Appearance: Action Comics #1 by Jerry Siegel and Joe Schuster
Although Superman originates from the DC Universe, his brief yet impactful crossover interactions with Captain America spotlight a bond formed between two iconic figures. Their relationship has evolved from rivalry to respect, culminating in memorable moments, such as when Captain America lent his shield to Superman, signifying trust and partnership.
The extraordinary scene of Superman wielding both Captain America’s shield and Thor’s Mjölnir illustrates the unique connection these two heroes share. Despite crossing over between universes, Superman stands as a testament to being one of Captain America’s strongest allies—not just in sheer power, but also in shared heroic values.
