Massacre in Hunan

"Years ago, a village in the Hunan Province in China. It was destroyed, every man, woman, and child torn apart by monsters trying to find that baby." "Did the monsters kill the baby's parents?" "No. That's what's so interesting. The baby's parents were the monsters."

- Raina and Grant Ward

The Massacre in Hunan was an mass assasination at Hunan village orchestrated by Jiaying and Calvin Zabo.

Background
In 1989, a group of HYDRA operatives claiming to be S.H.I.E.L.D. raided the village in Hunan and abducted several of the elders, including Jiaying. They brought Jiaying and the elders to Austria, where Jiaying was horrified to find herself reunited with Daniel Whitehall who was released from prison. When Whitehall saw that Jiaying was alive and physically unaged, he vivisected the woman and used her blood and organs to regain some of his youth. Then Whitehall had Jiaying's body disposed of in the wilderness.

Calvin Zabo, her husband, left their daughter Daisy Johnson among people he trusted, and set off to search for his wife. He later found her body remains in Austria. Using his medical skills, Zabo stitched her body back together until her Inhuman powers allowed her to recover and return to life.

Massacre
When Zabo and Jiaying returned to their village, she manipulated Zabo into getting her various villagers so she could absorb their life forces and heal her wounds. Zabo had killed many of the HYDRA operatives and civilians that went to the village, and S.H.I.E.L.D. tasked one of his teams, that included rookie agents Linda Avery and Richard Lumley, to investigate an 0-8-4 in Hunan, assuming the entire village died trying to protect the object. As Avery and Lumley lost communication with the first team sent, they investigated the area and found their senior agent under a bridge with a fatal wound, having managed to escape with the 0-8-4 but ultimately dying while doing so.

The object turned out to be a baby girl, who had fallen asleep in the dead agent's arms, and the five surviving agents took the baby and returned to the United States, where they began to be killed one by one, being Lumley the only survivor, although Avery devised a plan to erase all information about the baby and put her under an invisible protocol so that the foster system moved the child every few months in order to protect her.

Aftermath
To ensure her safety, Daisy was dropped off at the Saint Agnes Orphanage. Years later, she became a brilliant hacker, deleted all official records on her "Mary Sue Poots" identity and gave herself the name Skye. During her life, Skye was a member of Rising Tide, became an agent of S.H.I.E.L.D., met her parents and learned the truth about her real identity.
