Mjölnir’s history in Marvel Comics is rich with mythology and fascinating details that reveal its depth as more than just a weapon. First introduced in Journey into Mystery #83 (1962), the hammer has become synonymous with Thor and the ideals of heroism. Forged from Uru, a nearly indestructible metal, Mjölnir was crafted in the heart of a dying star by the dwarven blacksmiths Brokkr and Sindri. Odin’s enchantment was added later, after the hammer proved too dangerous for ordinary use, with its overwhelming power capable of causing massive destruction.

This enchantment not only restricted who could wield it but also gave it the ability to channel magical energy, summon storms, and serve as a conduit for Thor’s godly might. Thor’s hammer doesn’t simply respond to strength or skill in battle. It aligns itself with those who demonstrate courage, selflessness, and a higher moral code. Worthiness is not about perfection but about intent and heart. Thor himself has been deemed unworthy at times, showing how Mjölnir holds even its primary wielder accountable.
5. Beta Ray Bill

Beta Ray Bill’s worthiness to wield Mjölnir was a moment that shook the very foundations of Marvel’s cosmic storytelling. Introduced in Thor #337 by Walt Simonson, Bill appeared as an alien protector of his people, the Korbinites. Initially, he seemed like an adversary — a monstrous figure who battles Thor for control of Mjölnir. But when Bill unexpectedly lifts the enchanted hammer during their fight, even Odin is taken aback. The All-Father declares Beta Ray Bill worthy, leading to a stunning twist where Thor temporarily loses his claim to the weapon.
As a reward, Odin crafts Stormbreaker, an equally powerful weapon, specifically for Bill. This story not only gave fans a new hero but also expanded the mythos of Mjölnir, proving that worthiness isn’t confined to Asgardian royalty. Bill’s tale remains one of the most iconic examples of Marvel turning expectations on their head.
4. Captain America

Perhaps one of the most cheer-worthy moments in Marvel Comics happens in Fear Itself #7, when Steve Rogers, the ever-noble Captain America, picks up Thor’s hammer in the heat of battle. With Thor incapacitated and Earth teetering on the brink of annihilation, Cap proves himself worthy by embodying all the qualities Mjölnir demands: courage, humility, and an unshakable moral compass. Watching him wield the hammer is nothing short of exhilarating, as he uses it to rally the Avengers and deliver a much-needed victory against the Serpent. His worthiness proves that humanity can stand shoulder to shoulder with divine forces when the stakes are highest.
3. Jane Foster

Jane Foster’s journey to becoming Thor in Jason Aaron’s critically acclaimed run (Thor vol. 4, 2014) is one of the most transformative stories in recent Marvel history. When Thor becomes unworthy of wielding Mjölnir, the hammer seeks out Jane, who is battling cancer at the time. Despite her frail mortal body, Jane takes up the mantle of Thor, transforming into a powerful goddess every time she wields the hammer. Her story is deeply emotional, as every transformation reverses the effects of her chemotherapy, worsening her illness — but she never hesitates to fight for what’s right.
Her struggles with mortality and strength made her a deeply relatable and inspiring hero. Many fans were initially skeptical of someone replacing Thor, but Jane’s tenure proved that Mjölnir chooses based on the truest sense of heroism, not lineage or brute strength.
2. Storm

In X-Men: To Serve and Protect #3, Storm has a remarkable moment where she briefly wields Mjölnir, showcasing her deep connection to the forces of nature. The story unfolds when Thor brings her Stormcaster, a mystical hammer originally created by Loki. Upon touching Stormcaster, Storm transforms into a “Thunder Goddess,” but the hammer’s influence begins to take hold of her. To free Storm from its control, Thor encourages her to join him in wielding Mjölnir. Together, they channel the power of both hammers to destroy Stormcaster.
Though Storm doesn’t wield Mjölnir alone, the moment underscores her inherent worthiness. Her ability to command the elements mirrors Thor’s divine powers, making her a natural counterpart to the God of Thunder.
1. Superman: The Ultimate “What If?”

In the legendary Marvel/DC crossover JLA/Avengers (2003), Superman momentarily wields Thor’s hammer during a climactic battle. While the crossover’s rules initially make it clear that no DC hero should be able to lift Mjölnir, Superman’s unparalleled purity of heart and unwavering sense of justice allow for an exception. This brief moment, where Superman wields both Mjölnir and Captain America’s shield, is an unforgettable image that fans still talk about to this day. While it’s technically a “what if” scenario, it underscores the thematic similarities between Superman and Thor: both are powerful protectors driven by unshakable morals.
