History
The Crane Daughters are the children of the Crane Mother the ruler of K'un-Zi. The Crane Mother has given birth to thousand of daughters of the centuries, but can only give birth to a son the Crane Champion every 300 years. They are all trained in K'un-Zi martial arts. Together they can merge into a giant Crane.[1]
With the death of the Crane Champion they recruit the Steel Phoenix to take revenge against Iron Fist (Orson Randall). They sacrificed their Chi to the Steel Phoenix to enhance his powers, with the Crane Mother sending more daughters whenever they ran out.[2][3]
