Agents of S.H.I.E.L.D.
Little is known about her past, but when Skye was an infant, her parents ravaged a village in Hunan province. A group of S.H.I.E.L.D. agents found her and classified her as an 0-8-4. Skye became an orphan and got sent to St. Agnes orphanage by the S.H.I.E.L.D. group. She was named Mary Sue Poots. She got renamed to Skye. She wanted to find the truth about her parents so much, she joined the Rising Tide with help from Miles Lydon.

She spent two years in her van to hack details about S.H.I.E.L.D. until she got captured. She later joined S.H.I.E.L.D. after tranquilizing Michael Peterson. Skye went on a mission on Malta about finding Franklin Hall from Ian Quinn. One day, while finding Centipede, Skye was found by Miles Lydon. As a result, Skye got a deadly consequence: a Tracking Bracelet which disables her from using electronics. When Coulson got captured and overlooked the truth about his revival, Skye saved him. As a result, the Tracking Bracelet got deactivated. Later, Coulson told Skye the truth about her parents and her status as an 0-8-4.

On a mission at Italy, Skye came across Ian Quinn and Michael Peterson who later became Deathlok. Ian Quinn shot Skye twice at the stomach. Skye was found by Coulson's team for recovery. At the Guest House, the team found GH.325, the drug that saved Coulson's life. The drug has been used on Skye, which helped her recover. After Sif and Lorelei appear, Coulson tells Skye that the drug they used came from a blue alien. Skye realizes that she and Coulson must find out why Coulson was revived. On a secret phone line, Melinda May says to Nick Fury that "Coulson knows" about the truth. Skye later became a Clearance Level 1 agent until HYDRA exposed their infiltration.

It was later revealed that she has Inhuman heritage, and was exposed to a Terrigen bomb, which unlocked her Earth-Quake powers.

She later stood along with Nick Fury watching the four remaining Avengersat the Avengers Mansion, waiting for the Skrull imposter to reveal himself.

During the invasion, Daisy was with Fury and Natasha, trying to discover who was a Skrull, but is quickly knocked unconscious by Queen Veranke, who had been posing as the captive Mockingbird.
