Marvel's Iron Fist Season 2: What Does The Ending Really Mean?
5. Colleen Is The Iron Fist...
Whatever you say about Iron Fist, you can't accuse the show of resting on its laurels. Over the past two seasons, Danny has lost and regained the Fist numerous times and by the end of season 2 he voluntarily hands over the power to Colleen, which sets up a pretty major shake-up of the status quo in season 3.
When we last see Colleen, she has taken over from Danny (and, by extension, Matt Murdock), as the protector of the streets of New York. In a neat twist on the established powers of the Iron Fist, she even siphons her power through her katana to make it glow - which sets up a similar situation we'll get to in a minute.
Seeing how much the power of the Fist jumps around on this show, it's hard to say whether Colleen will get to keep it full time. However, the other revelation from the finale to do with the character suggests this development is going to stay...
