How Iron Fist Changes Typhoid Mary From the Comics for the MCU

Mary Walker in Iron Fist

WARNING: The following article contains spoilers for Marvel's Iron Fist Season 2, streaming now on Netflix.

One of the biggest additions to the second season of Marvel's Iron Fist is Alice Eve as Mary Walker, who emerges as both an enemy and an ally for Danny Rand.

Better known to Marvel fans as Typhoid Mary, the Daredevil foe was introduced 30 years years ago, so it's interesting to see how much her television depiction differs from her comic book counterpart.

The biggest difference, of course, is that she makes her live-cation debut as an Iron Fist character rather than a Daredevil antagonist.

Typhoid Mary was introduced in 1988 during the acclaimed Daredevil comics run of Ann Nocenti, John Romita Jr. and Al Williamson.

On both Iron Fist and in the pages of Daredevil, Typhoid Mary has dissociative personality disorder, a mental disorder in which she possesses multiple personality states. In Iron Fist's second season, her "Mary" persona reached out to Danny Rand, similar to how she initially made contact with Matt Murdock in the pages of Daredevil.

However, there is a difference between the first meetings, in that the comic book "Mary" seemed to be working alongside the more dominant "Typhoid" personality, who was a killer. On Iron Fist, the dominant personality is called "Walker" and she actively doesn't want "Mary" to contact Danny. She even warns her with a series of Post-It notes placed around the apartment.

Perhaps the biggest difference between the two is that while both versions are skilled fighters, the Iron Fist version is "just" an extremely skilled fighter.

While the comic book version has telekinetic powers, which she exhibited early in her first appearance.

As well as pyrokinesis. While alluded to early in her first appearance in Daredevil #254, it was outright demonstrated when she broke into the office of Wilson Fisk (the Kingpin of Crime) as a sort of audition to work for him as his main assassin.

In the comics, she is mostly known for her steady gig working for the Kingpin. She even sub-contracted out other killers to attack Daredevil. However, she was always restrained by her "Mary" persona, which held her back in her various battles against ol' Hornhead.

On Iron Fist, "Walker" has been hired by Joy Meachum and Davos to capture Danny Rand as part of a plot to steal the Iron First from Danny through an ancient ritual. However, as opposed to the comic book version of Typhoid Mary, she is easily wooed to the other side by Danny and Ward Meachum offering her a half a million dollars to work for them instead.

When we learn about Mary's background on Iron Fist, we discover that there quite possibly is a third personality far more dangerous than "Walker." This holds true to the comics, where the third personality is known as "Bloody Mary," and she holds true to that name as she just slaughters people, although typically with a bit of purpose. For instance, she once fought against Spider-Man while she was trying to eliminate men who were domestic abusers.

Speaking of Mary's background, that's another area that differed greatly from the comics...
