The story of "Iron Fist" is inspired by the original Marvel comic of the same name. In the comic, "Iron Fist" Danny Rand is a martial arts master trained in the mysterious city of "Kunlun". He obtains divine power from the immortal dragon Shou-Lao and can gather qi into his fists to be indestructible. Colleen Wing, who has Asian ancestry, has lived in Japan since childhood and learned various skills of samurai. She met Rand during an operation and became his right-hand man in fighting crime. The show will be jointly created by Marvel, ABC and Netflix, and the specific start time is yet to be determined. With the announcement of the heroine, the producer also released a concept map to celebrate. The poster on the wall in the picture was torn off in half, and the remaining part of the text was vaguely visible, with the words "Self-Defense Martial Arts Teaching Class" and "Master Colleen Wing" printed on it.
