Dr. Jay Felger is a scientist working at Stargate Command. He hero-worships SG-1 and is infatuated with Major Samantha Carter, although his assistant Chloe Angstrom is infatuated with him. He is a close friend to Dr. Simon Coombs. He previously worked as a lecturer at the Massachusetts Institute of Technology .
Felger, a physicist, was leading a team of other scientists, Dr. Simon Coombs and Dr. Meyers, in a project to excavate a ring platform on the planet P5X-112. While there, SG-1 was seemingly taken captive by a group of Jaffa who took them onto a ship in orbit. Even though Colonel Jack O'Neill had left them with specific instructions on what to do, Dr. Felger felt that he needed to be the hero and save the team upon witnessing the abduction. Felger didn't know that SG-1 had purposefully arranged to be captured so that they could get an audience with a Tok'ra operative, Khonsu, who had information about Anubis.
Felger sent Meyers back to Stargate Command to inform Major General George S. Hammond while he and Coombs used the ring transporter they had been working on to beam up to the ship. There, they located SG-1 and told them that they were there to help them escape. O'Neill was angry that Felger and Coombs ignored his orders, but after things went wrong on the mission, he was glad that they had decided to help. Felger and Coombs used their knowledge of Goa'uld technology and language to help SG-1 escape, after discovering for real, that Khonsu was killed by his First Prime, Her'ak. Both him and Coombs along with the rest of SG-1 managed to escape through the Stargate, before Her'ak and his Jaffa could capture them and bring them before Anubis. (SG1: "The Other Guys")
Later, Felger invited Major Samantha Carter and Colonel Jack O'Neill to a demonstration of his latest project, a Plasma weapon, but the device failed and took out the power in the base. Major General George S. Hammond was on the verge of firing Felger because of his continual failures, but Carter asked that he give him one more chance, personally sticking her neck out on the line for him. Along with Felger's lab assistant, Chloe Angstrom, the three decided to use the computer virus called Avenger, to show that Felger had something worthwhile to offer. This virus ran inside the crystals of a DHD and would render the selected Stargate inoperative. Carter pitched the idea to Hammond and he reluctantly approved. They picked one of Ba'al's planets, P5S-117, where there was a Naquadah mine. They reasoned that if they were able to stop the flow of naquadah from this mine, then Ba'al's naquadah network supply would be severely disabled.
They sent the virus through and it did what it was supposed to do. However, soon, they found that all the Stargates in the network were becoming inoperative, disrupting Stargate Command operations as well. Three SG teams were stranded, including Dr. Daniel Jackson who was trapped on P3L-997, where the flood waters were rising, and Teal'c and O'Neill, who were stranded on P3C-249 in the middle of a brutal firefight.
Carter and Felger worked fervently to determine what went wrong. Since the SGC didn't use a DHD, they were the only ones who could dial out. They decided to send Carter and Felger to Ba'al's planet, P5S-117, to upload an anti-virus. When they got there, they discovered that it was Ba'al who had modified the original Avenger program and had taken down the Stargate network. He used this opportunity to attack his rivals in his many ships where there was no means of escape through the Stargate.
Felger uploaded a new program into the originally infected DHD and used the coordinate database to transmit the changes to the other Stargates. Eventually, the network would come back "online" and the DHD would operate as before, but with Felger's new anti-virus program to prevent this type of tampering again. Felger and Carter were rescued by O'Neill and Teal'c who had procured an Al'kesh.
Felger was so infatuated with Carter that he didn't realize that Chloe had admired him and had even become infatuated with him. Even though she gave him a good luck kiss before he embarked on his dangerous assignment, he was still too wrapped up in himself and his affection for Carter to notice. (SG1: "Avenger 2.0")
Personality and traitsEdit
Although his actions do not always show it, Felger is considered a brilliant scientist. He has some problems, however, separating his fantasies from his job. He has built a small model of the Stargate and SG personnel in his home, much like one would build a miniature train set with its surrounding village. He also fantasizes about Major Samantha Carter as a love interest and thinks that Colonel Jack O'Neill considers him a great friend. (SG1: "The Other Guys", "Avenger 2.0")
