The following contains spoilers for Daredevil #5, now on sale from Marvel Comics
Daredevil has always been one of Marvel's most unique figures. His civilian identity is a part of the legal system he so often disrupts while in costume. He has always been an interesting contrast to most of the Marvel Universe -- but the vigilante may have just found his true opposite number.
Daredevil and U.S. Agent (John Walker) end up facing off in Daredevil #5 (by Chip Zdarsky, Marco Checchetto, Matthew Wilson, and VC's Clayton Cowles). Matt Murdock uses the fight to make a compelling case that the pair are as different as night and day -- something that could easily come up if the two ever confronted each other in the MCU.
Daredevil Vs. the Worst Captain America
Daredevil has increasingly found himself isolated from the greater Marvel Universe, especially now that he's allowed the world to believe Matt Murdock was killed during the events of Devil's Reign. Working alongside and marrying his longtime flame Elektra, Daredevil has taken command of the Fist and plans to use them to finally bring down the Hand and prevent their dark intentions for the future of the Marvel Universe. The latest development in his plan requires recruiting more people to fight alongside him, leading him to enact a breakout at the sea-based Myrmidon prison.
While Elektra successfully assists fifteen villains in escaping captivity, Daredevil finds himself pitted against John Walker. The former Captain America orders him to surrender and quickly trades blows with the vigilante -- but it's quickly clear that Daredevil has the advantage in the battle. Even beyond the physical element of the brawl, Daredevil comments internally about how John is the "worst of us," seemingly referring to the larger superhero community. He considers Walker an authoritarian, who embraces fear because that's all he truly understands. By contrast, Daredevil embraces faith at the heart of his decisions, making him a man without fear -- and Walker's opposite number.
Daredevil and U.S. Agent are Perfect Foils
It's an interesting concept and one that speaks to the history of both characters. Walker has often been defined by his darkest actions and his commitment to a grander ideal beyond himself -- one that often puts him at odds with the rest of the hero community. Daredevil may act illegally in the eyes of the law, but his actions have always been driven by his desire to help others, regardless of the means. John is a believer in order above all else, something the more chaotic Daredevil resists while in costume. Daredevil's belief in equal treatment would bristle naturally against Walker's more brutal application of "justice," and Walker's loyalty to the system above all else stands in stark contrast to Daredevil's willingness to rebel.
It's an interesting way to turn the most controversial Captain America into a direct foil to Daredevil -- and it's something that could easily come into play in the MCU. John Walker briefly replaced Captain America in Falcon and the Winter Soldier, and his hardened approach to crime fighting will see him play a part in the upcoming Thunderbolts film. Meanwhile, She-Hulk brought back Charlie Cox as Daredevil and will explore one of his most iconic -- and authority-bashing -- storylines with the upcoming Daredevil: Born Again series. Thanks to the interconnected nature of the universe, the pair could easily find themselves pitted against each other in some capacity down the line on screen.
