While Marvel has gone out of its way to prove Quicksilver and Scarlet Witch’s powers aren’t like their father’s, a comic once showed that the speedster had his own Magneto-like abilities. In Quicksilver #12, the titular hero was stuck in chains but channeled his father’s powers to break free. While it was an extraordinary moment, Marvel never revisited the surprising powers and, over time, completely forgot it ever happened.
Quicksilver originally debuted alongside his sister Scarlet Witch as a member of the Brotherhood of Evil Mutants. The pair worked alongside Magneto before turning into heroes and joining the Avengers. For years, the comics considered Pietro Maximoff to be the son of Magneto. That idea’s been retconned out of current Marvel continuity, but it was considered true for years – leading to writers exploringQuicksilver’s heritage. However, in the mid-90s, the hero was still the offspring of the supervillain and somehow he used his father’s powers himself to break free from a tricky situation.
In Quicksilver #12 by John Ostrander, Joe Edkin, Derec Aucoin, Rich Faber, Joe Rosas, Richard Starkings, Albert Deschense, and Mark Bernardo, Pietro teamed up with the Heroes For Hire to storm Wundagore Mountain and locate its knights. In a battle with Exodus and Man-Beast, Quicksilver was taken down and captured. As he laid chained deep underground of the citadel in Wundergore Mountain, a man in a cloak approaches him and tells him to take action. After declining to help, the mysterious figure tells Quicksilver he is the son of Magneto and that his strength “flows through your body.” Quicksilver clenches his teeth as the voice tells him to harness Magneto’s powers – leading him to break free of the chains.
Marvel teased a follow-up to Quicksilver’s new abilities, but that time never really came. Instead, in the story, Quicksilver somehow channeled the powers of Magneto and used his magnetism to break free of his chains. Honestly, it makes sense Marvel abandoned the idea of Quicksilver having Magneto’s abilities, as it would have made the character far too overpowered. Furthermore, being a speedster with Magneto’s incredible powers would make him near-unbeatable.
Ultimately, giving Quicksilver some of Magneto’s powers was a cool idea in theory but would have been difficult to continue long-term. Pietro is a speedster whose powers are impressive enough in their own right. Plus, Magneto’s daughter Polaris already takes after her father when it comes to powers. Changing Quicksilver would have taken away his own identity and needlessly tied him to his father when it wasn’t necessary. Quicksilver’s Magneto powers were appropriately short-lived and never expanded upon (at least to our knowledge).
