Superman

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

Superman's real-world genesis lies entirely outside the Marvel Comics framework. He was created by writer Jerry Siegel and artist Joe Shuster, and first appeared in Action Comics #1 in June 1938, published by National Allied Publications, which would later become DC Comics. His creation single-handedly launched the superhero genre and the Golden Age of Comic Books, establishing the core tenets of the archetype: dual identity, superhuman abilities, an altruistic mission, and a distinctive costume. His history with Marvel, however, begins much later and is a landmark tale of inter-company collaboration. The first and most famous meeting occurred in the 1976 treasury-sized special, Superman vs. The Amazing Spider-Man: The Battle of the Century. This project was a massive undertaking, co-published by both Marvel and DC, and written by Gerry Conway with art by Ross Andru (both of whom had extensive careers at both companies). The success of this book proved that such collaborations were not only possible but immensely popular, paving the way for future crossovers. Subsequent major appearances include:

These crossovers are generally considered to be non-canonical to the mainstream Earth-616 timeline but are treated as significant historical events within the broader Marvel Multiverse, often designated to their own temporary or alternate Earths. They represent moments where the barriers between realities thinned, allowing for these legendary encounters.

In-Universe Origin Story

A critical distinction must be made: Superman, as the individual Kal-El from Krypton, does not have an origin within the Earth-616 universe. His existence is external. When he appears, he brings his established DC Comics origin with him. The following sections detail how that origin is presented in his Marvel encounters and how the MCU has handled his absence.

Earth-616 (Prime Comic Universe)

When Superman crosses over into the Marvel Universe, his established origin is accepted as fact by the characters he meets. This origin is consistently portrayed as follows: Born Kal-El on the dying planet Krypton, he was placed in a small rocket by his scientist father, Jor-El, and sent to Earth to escape the planet's destruction. The rocket landed in rural Smallville, Kansas, where the infant was discovered by farmers Jonathan and Martha Kent. They raised him as their own son, naming him Clark Kent. As he grew, Earth's yellow sun activated his Kryptonian physiology, granting him incredible powers: flight, super-strength, invulnerability, heat vision, and more. As an adult, Clark moved to the bustling city of Metropolis and became a reporter for the Daily Planet. He uses this unassuming civilian identity to stay informed while operating publicly as the costumed hero Superman, a champion of “Truth, Justice, and the American Way.” This entire backstory is imported wholesale during crossovers. For example, in JLA/Avengers, captain_america visits Superman's Earth and is given a condensed psychic overview of his life, accepting it as the history of that world's greatest hero. While Superman himself is not native to Earth-616, his archetype has given rise to several major in-universe characters who explore different facets of his concept:

Marvel Cinematic Universe (MCU)

Superman does not exist in the Marvel Cinematic Universe (designated as Earth-199999). There have been no crossovers, and the character is not part of the established canon. The intellectual property is owned by Warner Bros. Discovery, a direct competitor to Marvel's parent company, Disney. However, the MCU has deliberately introduced and developed its own characters who fill a similar narrative space and explore the “god among mortals” archetype. The two most prominent examples are Captain Marvel (Carol Danvers) and Ikaris.

Part 3: Abilities, Equipment & Personality

Earth-616 (Crossover Appearances)

During his canonical crossover appearances, Superman's powers are depicted as being consistent with his mainstream DC Comics version of the era. His power level is shown to be at the absolute highest echelon, rivaling and in some cases surpassing Marvel's mightiest heroes.

Powers & Abilities

Weaknesses

Personality

Across all his Marvel appearances, Superman is portrayed as the quintessential hero. He is calm, compassionate, and possesses an unshakable moral compass. He often clashes ideologically with some of Marvel's more pragmatic or aggressive heroes but ultimately earns their profound respect. His interactions with Captain America are particularly noteworthy, as the two quickly recognize each other as kindred spirits—men of unwavering principle and symbols of hope for their respective universes.

Marvel Cinematic Universe (MCU)

As Superman is not in the MCU, this section analyzes the powers and equipment of his closest analogues.

Ikaris (The Eternals)

Ikaris serves as the “powerhouse” of the Eternals, a clear stand-in for the Superman role on the team.

Captain Marvel (Carol Danvers)

Carol Danvers fills the role of the MCU's premier cosmic powerhouse, a position often occupied by Superman in DC lore.

Part 4: Key Relationships & Network

This section focuses on the relationships Superman forged during his crossover appearances with Earth-616 characters.

Part 5: Iconic Events & Storylines

Superman vs. The Amazing Spider-Man (1976)

The first official meeting between the two company flagships. The plot sees Lex Luthor and Doctor Octopus teaming up, manipulating Superman and Spider-Man into a misunderstanding-fueled brawl. Superman, believing Spider-Man is involved in a kidnapping, attacks the web-slinger. The fight is brief but iconic, showcasing the vast power difference but also Spider-Man's incredible agility and refusal to give up. After realizing they've been tricked, they join forces. The story is a masterclass in crossover storytelling, respecting the core tenets of both characters while creating a credible, high-stakes threat. It established the friendly, respectful dynamic that would define their future interactions.

DC vs. Marvel Comics (1996)

This company-wide event pitted the heroes of both universes against each other in a series of duels, with the outcomes determined by fan votes. The universes are personified by two cosmic “Brothers” who have become aware of each other again after eons. Superman's key battle is against the Hulk. Due to his immense speed and strategic use of heat vision, Superman wins the fan-voted fight decisively. The event's most lasting impact was the creation of the Amalgam Universe, where the heroes were temporarily merged. Superman's role in the event solidified his status as the premier hero of his universe, chosen to fight for its very existence.

JLA/Avengers (2003-2004)

This is the definitive Marvel/DC crossover, a love letter to both universes crafted by Kurt Busiek and George Pérez. The story involves a cosmic game between the Grandmaster (Marvel) and Krona (DC), forcing the Justice League and the Avengers into conflict and then a desperate alliance. Superman's role is central. His initial fight with Thor is a highlight, a cataclysmic battle between titans that shakes the very foundations of the Savage Land. The story's most defining moment for Superman comes in the final issue. As the heroes make their last stand against Krona, a dying Thor throws Mjolnir to Superman. He effortlessly catches it, alongside Captain America's shield, and leads the final charge, proving himself “worthy” in the eyes of Asgardian magic. This act is the ultimate sign of respect from the Marvel Universe, acknowledging that Superman's nobility and heroism transcend the boundaries of any single reality.

Part 6: Variants and Alternative Versions

While Superman himself has no “variants” in the Marvel sense (like Loki's variants in the MCU), the Marvel Multiverse is filled with characters who are deliberate analogues, homages, or deconstructions of his archetype.

Hyperion (Squadron Supreme)

The most direct and long-standing Superman analogue in Marvel Comics. There are several notable versions:

The Sentry (Robert Reynolds)

Introduced in 2000, the Sentry was presented as a “lost” Silver Age Marvel hero, a contemporary of the Fantastic Four who had been erased from everyone's memory. He is Marvel's examination of the Superman archetype through the lens of mental illness. Robert Reynolds is a kind, heroic man, but he is inextricably linked to the Void, a malevolent entity of pure darkness that is the negative aspect of his own power. For every good deed the Sentry performs, the Void commits a corresponding act of terror. This duality makes him one of Marvel's most powerful and tragic heroes, a man who is terrified of his own shadow and the immense power he wields.

Gladiator (Kallark)

As leader of the Shi'ar Imperial Guard, Gladiator is a Superman figure in service to an alien empire. His powers are a direct parallel to Superman's, but they are psionically fueled by his own self-confidence. When he is determined and unwavering, he is nearly unstoppable. When his faith wavers, his powers diminish. This provides a fascinating psychological weakness, tying his physical strength directly to his mental state. He represents a Superman whose morality is not defined by human values, but by his sworn duty to the Shi'ar throne, which has at times placed him in conflict with Marvel's heroes.

Notes and Trivia

1) 2) 3) 4) 5) 6)

1)
Superman's real name, Kal-El, is echoed in the name of the Shi'ar Gladiator, Kallark. His human name, Clark Kent, is also part of the portmanteau.
2)
The classic 1976 crossover was so successful partly because Carmine Infantino, the publisher of DC Comics, and Stan Lee, his counterpart at Marvel, were good friends and were able to negotiate the terms of the historic co-publication.
3)
In the JLA/Avengers crossover, Superman is visibly awed by the sheer number of active heroes on Marvel's Earth compared to his own, noting that the Avengers are a much larger and more sprawling organization than the Justice League.
4)
The concept of a hero being “worthy” to lift Mjolnir is a core tenet of Marvel lore. By allowing Superman to lift the hammer, writer Kurt Busiek was making a definitive statement about Superman's character being on par with Marvel's most noble heroes, like Captain America and Thor.
5)
An earlier JLA/Avengers crossover was planned in the 1980s, to be written by Gerry Conway and drawn by George Pérez. A dispute between the companies over editorial control led to its cancellation after Pérez had already drawn over 20 pages of artwork. His eventual work on the 2003 series was seen as the fulfillment of a long-held dream for many comic fans.
6)
The fan voting for DC vs. Marvel was controversial. While some results were predictable (Superman > Hulk, Spider-Man > Superboy), others, like Wolverine > Lobo and Storm > Wonder Woman, sparked intense debate among fans for years.
