For fans of Marvel ComicsDaredevil may not be an obvious choice for the Avengers. Because of his street-level sensibilities, Daredevil has admitted that he doesn't like big crossover fights that the Avengers are known for, because it's easy for him to get lost in the noisy mix. Even so, Daredevil's comics have repeatedly challenged the notion that a hero's worthiness is commensurate with their power levels. Sure, Daredevil may not have the flashiest powers in the Marvel Universe, but that doesn't mean he lacks personal qualities that make him adept at taking down some of Marvel's biggest villains. In one of his bleakest comic moments, Daredevil singlehandedly defeated Ultron, a fact would surprise MCU fans.

Created by Hank Pym, Ultron is one of the most formidable villains in the Marvel Universe with his high level of intelligence, calculating nature, and physical durability as an adamantium robot. He was brought to the Marvel Cinematic Universe with the film, Avengers: Age of Ultron, which adapted elements from the 2013 Age of Ultron comic event by Brian Michael Bendis, Bryan Hitch, and Brandon Peterson. While the MCU version of Ultron (and his Age of Ultron comics predecessor) necessitated the strength of all the Avengers combined in order to defeat him, his previous fight with Daredevil revealed a hidden weakness that makes him strikingly human, despite his robotic nature.

In Daredevil #276 by Ann Nocenti, John Romita Jr., Al Williamson, Joe Rosen, and Max Scheele, Ultron is obsessed with achieving perfection, attacking anyone who stands in his way. After Ultron kidnaps one of Daredevil's allies, Number Nine, who he deems "perfect," Daredevil locates an increasingly unstable Ultron in a junkyard. Torn between his desire for perfection and his programming that tells him to kill Daredevil, Ultron begins ripping out his own circuits, saying, "Which is the one that keeps me from experiencing happiness? Too many voices! Which one, which one! Which voice is the right one?" In doing so, Ultron unknowingly makes himself vulnerable to Daredevil, who he later calls "the perfect man." Armed with a tree branch, Daredevil denies being a "perfect man," saying, "No. Far from it. The perfect man would have found a better way – than this" before knocking the robot's head off with a tree branch.

Daredevil kills Ultron with a tree branch in Marvel Comics.

This incident in Daredevil's comics prove that having him on the Avengers in the MCU would have instilled a unique humanistic bent to the team, contrasting the sound and fury of the kinetic Avengers: Age of Ultron film. Simply by being Marvel's most principled superhero, Daredevil defeated Ultron without relying entirely on his fists. For Daredevil, overcoming a powerful villain like Ultron isn't a victory to be celebrated or commemorated for–it's evidence of his own paradoxical moral code.

A theme of perfection continues to circulate in contemporary Daredevil comics, itself a reflection of the impossibility of Matt Murdock's morality as a Catholic vigilante. It was also featured heavily in the Daredevil Netflix series that took place on the fringes of the MCU. While it is difficult to imagine Nocenti's Daredevil or the MCU's Daredevil in the Age of Ultron film, his comics show how his particular themes as a superhero would have made the Avengers a much more complicated team, a fact later explored in Captain America: Civil War. This instance proves that Daredevil has always been ahead of the times in terms of his moral complexities, and with Matt Murdock officially back in the MCU, fans can hope to see more of this onscreen in the future.
