Iron Fist- I think the first season of the Iron Fist show should focus on Danny returning to New York to exact revenge on Harold Meacham and have his backstory told in flashback similar to the Island segments in Arrow. The first half of the season details Danny teaming up with Misty Knight and Coleen Wing to take down Harold. Misty wants to take out Harold because his corrupt and shady business deals cost Misty her right arm. Coleen joins Danny due to her father sending her to meet the new Iron Fist. Have the midseason end with Danny sparing Harold’s life only for him to be killed by a mysterious assassin. Just like in the comics. The second half of the season would follow Danny trying to combat Master Khan who sent the assassin to kill Harold. The villains I think Iron Fist should fight are mercenary’s sent by Harold in the first half, then more mystical villains under the command of Master Khan in the second. These villains are:
Harold Meacham: The villain of the first part of the season. Due to him letting Danny’s father die out of greed and lust for his wife Danny has developed a deep hatred for Harold and will stop at nothing to seek revenge.
Discus and Stiletto: Classic Heroes for Hire villains. They could make for some basic mercenaries who could return later on.
Killer Shrike: He could be a way to link the show to the MCU by having him be a mercenary fitted with stolen stark tech.
Cat: A master martial artist and assassin. He is also an enemy and rival of Shang Chi so he would be a good edition.
Shockwave: Another armoured merc. This guy’s got powers similar to Shocker but ten times as juiced up.
Master Khan: The big bad of the season. He has a vendetta against all Iron Fists and seeks to destroy Danny and the Iron Fist lineage. He’s a powerful sorcery with an army of plant like creatures called the H’ylthri at his disposal.
H’ylthri: A race of creatures who loathe and despise the residents of K'un-Lun, due to them being the originally residents. They join Master Khan to destroy K’un-L’un and Iron Fist.
Crane Mother: An associate of Master Khan who assist him briefly due to her hatred of Orson Randall, the Iron Fist before Danny. She appears for an episode saving her for season 2.
White Tiger- The assassin contracted to kill Harold Meacham. Danny and Coleen track her down to Madripoor. This is the first of what I like to call crossover episodes. To keep the characters fresh in viewers minds I think that once one season ends and another show starts the character from the previous show should appear. For example Daredevil, also on the trail of the Hand teams up with Iron Fist and they travel to Madripoor together.
Gin Goh- An immortal warrior imprisoned by the defenders of K’un-L’un. He is freed by Master Khan in exchange for his assistance.
References- I think that the Iron Fist show should make references and allusions to mainly mystical characters like Ghost Rider, Doctor Strange, Blade and Werewolf by Night. Iron Fist should help introduce the mystical side of the Marvel Universe to the MCU.
