Marvel has confirmed that Iron Fist season 2 is happening and will include the character Misty Knight.
Season 1 of Iron Fist premiered on Netflix earlier this year, introducing both Danny Rand aka. the immortal Iron Fist (Finn Jones) and the character Colleen Wing (Jessica Henwick) to the Marvel Cinematic Universe in the process.
Premiere dates for the new seasons of Daredevil, Jessica Jones, Luke Cage and Iron Fist have yet to be announced.
