Here's an interesting story; this isn't an 'official' redesign of the original 'Iron Fist' character Danny Rand at all. It's a rethinking of the character drawn by a fan, although that fan just happens to be Paulina Ganucheau, the artist behind 'Zodiac Starforce.' Not only that, it was drawn as a response to an argument about ethnicity rather than gender.
When Netflix decided to make an 'Iron Fist' series, some people hoped that an Asian actor would be cast in the lead role. This is because the 'classic' Danny Rand character is an old stereotype - a white man who happens to be great at Chinese martial arts. Netflix stayed true to the comics and cast a white actor, so Kris Anka drew an Asian rendering of the character in protest. Ganucheau took things a step further and gave us a female 'Iron Fist,' and her Dani Rand is so good that we think she deserves a life of her own.
