UPDATE: Marvel has removed the paragraph about Matt Murdock's appearance in Spider-Man: No Way Home from his live-action biography detailing his television history. The original story can be found in full below.
It's official -- Daredevil is canon to the Marvel Cinematic Universe.
After actor Charlie Cox reprised his role as Matthew Murdock in Spider-Man: No Way Home, fans questioned whether or not this was the same version of the character seen across all three seasons of the former Netflix series, or another variant for the MCU. Thanks to Marvel's website, fans now have their answer. An updated biography for Murdock's live-action timeline connects the dots between Daredevil Season 3 and No Way Home.
Towards the bottom of the biography, the second-to-last paragraph summarizes the ending of the show's final season, discussing the funeral for Father Lantom and Murdock making amends with his friends, Franklin "Foggy" Nelson and Karen Page. However, another paragraph has been added to summarize his brief appearance towards the beginning of No Way Home. The paragraph reads as the following:
Sometime later, Matt was hired as an attorney to defend Peter Parker, as Peter had been publicly outed as Spider-Man and accused of Mysterio's murder. Though Peter was legally cleared of any wrongdoing, Matt warned him he'd still have to face the court of public opinion and advised Harold "Happy" Hogan to hire a good lawyer. As if on cue, a protestor threw a brick through the window of the Parkers' apartment in support of Mysterio. Fortunately, due to his heightened senses, Matt was able to catch the brick before it hurt anyone inside. When Peter asked him how he was able to do that, Matt claimed it was because he was a really good lawyer and left it at that.
The "sometime later" appears to definitively confirm that Spider-Man: No Way Home takes place after Daredevil Season 3, or at the very least, this Matthew Murdock shares the same history as his television counterpart. While one question is now answered in fans' minds, more have been raised. Despite the events of Daredevil and Murdock now being MCU canon, there is no official word on whether the same goes for his Defenders teammates.
Out of the four main Defenders -- Daredevil, Jessica Jones, Luke Cage and Danny Rand/Iron Fist -- and Frank Castle/The Punisher, only Daredevil's biography is fully updated. Some of the characters' timelines cut off with the events of Defenders, and the only other later-released seasons touched upon as of writing are Jessica Jones Season 2, Luke Cage Season 2 and The Punisher Season 1. However, Daredevil's timeline does bring along Defenders into his MCU canon status.
If rumors and reports swirling about are true, Murdock's biography is going to need some more updates in the future. One report says that a reboot of Daredevil is in the works for the MCU, while other rumors claim that the character is set to appear in more than one of Marvel's Disney+ series, ranging from Moon Knight to She-Hulk and beyond. Though Murdock has yet to appear in any of these shows, Daredevil's main antagonist -- Wilson Fisk/Kingpin -- joined the MCU in the Hawkeye series. Fisk's biography has not been updated to include this though.
The entirety of Daredevil is now available to binge on its new streaming home, Disney+, along with all the other Defenders series. Spider-Man: No Way Home is available on digital now and releases for Blu-ray and 4K UHD on April 12.
