Colonel was an
USMC officer played by
Robert Patrick on
Television Show ''
Stargate Atlantis ''.
Col. Sumner was the military commander of the Atlantis expedition. He didn't like Major
John Sheppard or the fact that he has been pushed into the expedition. He made it clear to him that he wasn't here by Sumner's will and later admited to Lt.
Aiden Ford that he had a problem with Sheppard's record.
Minutes after their arrival at Atlantis, they found out the power source of the shield that was protecting the underwater city by keeping the sea at bay was failing. Col. Sumner led a mission to planet
Athos in search of a safe place to evacuate Atlantis personnel. Once there, he was captured by the
Wraith .
In the Wraith's hiveship, the Keeper choose him as a "meal". Although he tried to resist, she found out he came from a new, big "feeding ground": Earth. She tried to force him to reveal Earth's location by draining him of his life force, but he resisted.
When Major Sheppard found him, the Wraith Keeper had already drained him of most of his life force, and he decided to end Sumner's suffering by putting a bullet through his heart. It seemed a wise decision at the time, but it later earned Sheppard the enmity of Col.
Dillion Everett .
