Pilot and tech officer assigned to Earth's Daedalus-class deep space carrier group. Cooper piloted Daedalus during the ship's maiden voyage across the expanse between the Milky Way and Pegasus Galaxy to Atlantis, where she piloted the ship into combat with a Wraith hive fleet in defense of the city. A year later she piloted an F-302 support fighter launched from the Daedalus, engaging the Wraith alongside John Sheppard under the call sign "Dagger Two."
Sometime thereafter Cooper was reassigned to the Apollo, where she also served on the ship's bridge -- now under the command of Abraham Ellis. But she later returned to Steven Caldwell's command on the Daedalus.
Note: Emma Cooper's name appears on her uniform name tag in multiple episodes. She is sometimes credited as "Meyers." The name tag "Pat Meyers" appears only in her final appearance, in an alternate timeline.
