Edane

Edane was a young Eidolon who lived in an alternate reality. When Lt. Colonel John Sheppard's team arrived in the alternate reality he lived in, Edane showed a great interest in talking to them, but weirded the team out. During an assault on a Wraith scout ship, Edane accompanied the team and a few other Eidolons to destroy it, but was forced to beam out when he was surrounded by Wraith. After successfully destroying the Wraith ship, Sheppard noted no sign of Edane but figured he had simply left already. As Dr. Rodney McKay prepared the [{Quantum Mirror]] for the return to their reality, Edane showed up, claiming to want to help. However, Sheppard realized he was there to feed on them and struggled with Edane who disarmed both Sheppard and McKay. Before Edane could do serious harm, Trishen killed him with McKay's pistol. Trishen then explained that while the Eidolons did not need to feed on sentient beings, the instinct to do so still remained and some, like Edane, ultimately could not control that instinct and would have to be killed.
