Steel Serpent – Donnie Yen
With Iron Fist being in development, there really isn’t another choice besides Steel Serpent to face off against Mr. Danny Rand himself. They’re equals in many ways, and have the perfect yin and yang relationship in their villainy. Donnie Yen is a seasoned vet of martial arts films and one of the biggest actors in the genre today. He’d definitely fit the part of Steel Serpent!
