Marvel's The Defenders: Every Character Confirmed So Far
3. Colleen Wing
Confirmed By: An official Twitter announcement.
Plot Predictions: One of the newest additions to the Netflix Marvel Universe, having first appeared in Iron Fist, yet also one of the most welcome, Colleen will likely serve as the companion to Danny's part of the story in the show.
The two became lovers in Iron Fist, so we should get to see that relationship continue to develop here when he's away from the other Defenders. However, more so than perhaps any other supporting player, Colleen can also have a very personal stake in this and be of great use to the team out on the street.
Colleen proved in Iron Fist that she's a more than capable fighter - arguably even better, or at least more convincing, than Danny - which means she can actually be out there fighting with them. The fact that it'll be, in part at least, against the Hand only increases the chance of this, since she was involved with the 'definitely-not-evil-honest-guys' branch of the evil ninja death cult. She has inside knowledge they can utilise, and a personal reason to get involved.
