Iron Fist season 2 will introduce Alice Eve as Mary Walker a.k.a. Typhoid Mary, a villain typically associated with Daredevil, who has multiple personalities and psionic abilities. The casting announcement was made during the Iron Fist panel at San Diego Comic-Con 2018, debunking earlier speculation that Eve would be playing Lady Gorgon.

Mary is something of as tragic figure, suffering from serious mental illness that manifests in the form of several different personalities: Mary is shy and abhors violence; Typhoid Mary is a seductive assassin; and Bloody Mary is brutally and sadistically violent, with a virulent hatred of men. In addition to her skill with a sword, Typhoid Mary also has telekinetic and pyrokinetic abilities.

After Eve's character was revealed, a clip played that showed off some of her fighting skills. In the clip, Colleen Wing and and Misty Knight show up at Joy Meachum's apartment and quickly realize she's not alone. Joy was a sympathetic character for most of Iron Fist season 1, but by the end of the series she had grown to hate Danny Rand, and the last time we saw her she was plotting with Davos to kill Danny. It seems that in season 2 Mary will be allied with Davos and Joy, as the clip showed Mary emerging and taking out Misty easily, before fighting Colleen - who recognizes her. During the fight Mary pulls a sword on Colleen, but Joy orders her to stop.

Eve is perhaps best known for her role as Carol Marcus in Star Trek Into Darkness, and up until now her Iron Fist character has been kept a closely-guarded secret. However, set photos that emerged earlier this year saw Eve sporting Typhoid Mary's trademark red hair and bangs, while seemingly helping a wounded Danny Rand. This indicates that she may not appear in a straightforward villain role; since Mary has dissociative identity disorder, one of her personalities could actually be on the same side as the good guys. Another possibility is that she will start out as a friendly character, but become a villain along the way.

Marvel fans will not doubt be excited to see such a lethal villain brought to life in a show with a TV-MA rating, which will allow Mary to do her worst. Following criticism of the fight scenes in the show's first season, Black Panther fight coordinator Clayton Barber has been recruited for the second season, and in the footage shown at Comic-Con the fighting looked considerably improved. Iron Fist made a memorable guest appearance in Luke Cage season 2, so we're definitely looking forward to seeing the new and improved Danny Rand return in his own show this fall.
