3) Steel Serpent
When running through Iron Fist’s big villains, perhaps the first name you’ll come to is the Steel Serpent. When Davos – son of Lei-Kung – loses out on the mantle of the Iron Fist in favour of Danny Rand, he is banished from K’un-Lun and instead becomes the champion of its rival city, K’un-Zi, known as the Steel Serpent.
With as much a grasp of the mystical martial arts as Iron Fist, Steel Serpent is one of Danny Rand’s most formidable foes, so he will surely find his way to the small screen as soon as possible.
Plus, there has already been some evidence to suggest Davos will make an appearance in Iron Fist, as an easter egg hidden in season one of Daredevil alludes to the character (on each packet of Madame Gao’s heroin was the symbol that is tattooed on Steel Serpent’s chest).
Speaking of which…
