Throughout his history as a Marvel character, the Iron Fist has had an on-again, off-again relationship with Misty Knight, which gave us the first interracial kiss between superheroes back in 1977. Misty played directly into how Iron Fist and Power Man first met, but over the five decades since he's been a character, he and Misty have always been near each other. At one point, Misty's "Knightwing Restorations Ltd." agency would link up with the Heroes for Hire on their journeys.
Why this is important: While it's been confirmed that Misty won't be featured in Iron Fist, she will be appearing in The Defenders, so that's something to keep in mind as the MCU on Netflix continues to develop. Will Marvel eventually mirror their relationship in some way on-screen?
