DC Comics Houses a Few Heroes Who Are Even More Invulnerable Than Superman, So Who Are They?

DC has just dropped a bombshell: three unexpected Justice League heroes are even more invulnerable than Superman—at least in one surprising scenario. But this revelation is already sparking debate among fans, as past canon suggests that two of these heroes should share the same vulnerability as the Man of Steel when it comes to this mysterious magical artifact.

Jeff Parker, Lukas Ketner, Michele Bandini, and Marcelo Maiolo’s Christmas mini-series, Batman / Santa Claus: Silent Knight Returns, hits a high-stakes moment in issue #3 as DC’s heroes continue their battle against their latest overpowered foe, the Silent Knight.

The Silent Knight is a ghastly, armor-clad, sentient skeleton who wields a mystical sword capable of trapping and draining the powers of DC’s top champions, including Superman, Batman, Green Lantern John Stewart, Queen Nubia, Mera, and Thunderheart. With the team caught in a containment zone, Zatanna and Robin turn to reinforcements: Mary Marvel, Metamorpho, and Robotman—three heroes immune to the Silent Knight’s devastating power-draining weapon.

Batman / Santa Claus: Silent Knight Returns Reveals a Surprising Line-Up of ‘Invulnerable’ Heroes

Mary Marvel, Metamorpho, & Robotman Are Apparently Invulnerable to 1 Thing Superman Isn’t

Following Wally West’s apparent death at the hands of the Silent Knight, Zatanna resorts to one of her most powerful spells—a magical invocation that seeks out the heroes needed to defeat their overwhelming foe. The spell manifests as golden doves and carries a distress signal across the globe, specifically searching for “heroes who can’t be affected by the Knight’s sword.” Three doves return to Zatanna, delivering Mary Marvel, Metamorpho, and Robotman. This moment confirms that these three heroes are, surprisingly, even more invulnerable than Superman—at least when it comes to the Silent Knight’s power-draining weapon.

Previous issues of Batman / Santa Claus: Silent Knight Returns already hinted at Superman’s vulnerability to the Silent Knight, and issue #3 provides further confirmation during an exchange between Clark and Bruce. As the Silent Knight and his minions close in on the trapped heroes, Superman suggests clearing a path for his allies. Batman immediately shuts the idea down, warning, “Any power you expend becomes the Knight’s. At some point you could become a thrall like this one.” The implication is clear: if Zatanna’s spell has truly summoned the heroes capable of saving the day, then Mary Marvel, Metamorpho, and Robotman possess a critical edge—even beyond what the Man of Steel can offer.

While Zatanna makes it clear that Mary Marvel, Metamorpho, and Robotman are invulnerable to the Silent Knight’s sword, the reason behind their immunity remains uncertain. For Robotman, the explanation seems straightforward: as a robot, he lacks a life force for the Silent Knight to siphon. However, the apparent invulnerability of Mary Marvel and Metamorpho raises questions. Both heroes have been shown to be vulnerable to magic in past canon and are still relatively human in nature. This makes their immunity puzzling, leaving readers eager to see if Batman / Santa Claus: Silent Knight Returns #4 will shed more light on why these three Justice League heroes are uniquely impervious—even more so than Superman—in this particular battle.
