Marvel's "Iron Fist" is gearing up for a March 2017 release date on Netflix. Titles for the 13-episode debut season have been revealed, and one of them is going to showcase extreme violence.

Majority of the show's episodes are rated 15 for displaying violent scenes, according to Bleeding Cool's report from the British Board of Film Classification (BBFC), which has been rating and grading episodes of the upcoming program. Some episodes, however, went beyond a rating of 15.

Episode seven, titled "Felling With Tree Routes" and directed by Farren Blackburn, got an 18+ rating for depicting "strong bloody violence." This means that the entire DVD box set of "Iron Fist" will be rated 18 despite of the other episodes' lower ratings. It cannot be sold to consumers under the 18 years old.

The BBFC is known for being less tolerant over martial arts scenes, which will be put center stage in the upcoming program starring Finn Jones as Danny Rand. The regulatory board frowns upon the use of martial arts weapons such as nunchucks and flying stars because children and young people tend to copy them.

The show's episode titles and their respective directors are listed below. Details about episodes 10 and 12, however, are still unknown. Episode 11 downplays the violence of episode seven with its 12 rating and mildly violent scenes.

Episode 1: "Snow Gives Way" (John Dahl)

Episode 2: "Shadow Hawk Takes Flight" (John Dahl)

Episode 3: "Rolling Thunder Cannon Punch" (Tom Shankland)

Episode 4: "Eight Diagram Dragon Palm" (unnamed)

Episode 5: "Under Leaf Pluck Lotus" (Uta Briesewitz)

Episode 6: "Immortal Emerges from Cave" (Robert Fitzgerald Diggs a.k.a. RZA)

Episode 7: "Felling With Tree Routes" (Farren Blackburn)

Episode 8: "The Blessing of Many Fractures" (Kevin Tancharoen)

Episode 9: "The Mistress of All Agonies" (Jet Wilkinson)

Episode 11: "Lead Horse Back To Stable" (Deborah Chow)

Episode 13: "Dragon Plays With Fire" (Stephen Surjik)

In a Facebook Q&A from Extra, Jones revealed that episode six will showcase his superhero persona's origin, which involves Danny's battle in a cave that pushed him to channel the superhuman power of the Iron Fist. Danny is also an expert in kung-fu.

Jones told EW that Danny craves for a family unit and he might find that in the other members of the Defenders. However, something terrible will happen on "Iron Fist" and he will start doubting many people. "The Defenders" will be released later in 2017.

Also starring are Jessica Henwick, David Wenman, Rosario Dawson, Lewis Tan, Jessica Stroupe, Tom Pelphery and Carrie Anne Moss. The series bows on Netflix on Friday, March 17.
