Peter Kavanagh - List of Appearances

Dr. Peter Kavanagh is a male Tau'ri, a former member of the Atlantis expedition and a crew member on the Daedalus.


He worked at Stargate Command but was fed up with how the military dictated things so he joined with the Atlantis expedition. When Jumper One with personnel aboard was lodged in a Spacegate, he worked with a team to figure out how to rescue them. He grew concerned that the main drive could explode and come through the Stargate to Atlantis. When Dr. Elizabeth Weir shot this down in favor of the rest of the team thinking the chance was low, he followed her out and told her that he had been humiliated. She told him to get back to work and if he wasted anymore time she wouldn't hesitate to send him offworld as a punishment. He returned to work and after Meredith Rodney McKay has figured out how to retract the drive pods, Kavanagh realized that they could blow the rear access hatch to provide enough force to push the Jumper through the Stargate, saving their lives. (SGA: "Thirty-Eight Minutes")

When the expedition was sending a message back to Earth, he recorded a message for Jack O'Neill, highlighting and criticizing Weir's decisions. (SGA: "Letters From Pegasus") He was against trying to defend Atlantis from the incoming Wraith, stating that most of the expedition were scientists. (SGA: "The Gift") He returned to Earth after the siege, but a few months later asked Dr. Weir to allow him to come back. Three weeks after returning he resigned and boarded the Daedalus to return to Earth. After receiving word of a bomb on Atlantis, Kavanagh said they weren't close enough to send the message to the city and didn't believe that Hermiod could modify the engines to help them get in range. He was interviewed back on Atlantis by Weir who began to suspect him of being the one who planted the bomb as he had sent some coded messages back to the city. Ronon Dex came to interrogate him but he fainted before Ronon even touched him. (SGA: "Critical Mass")

He returned to Earth and in 2008 was stationed on the Midway Space Station. He was not happy with his posting. When the Wraith invaded the station and threatened to fed on him, he fainted. After the system was locked out to them, Kavanagh suggested the critical systems bypass and accidentally activated the auto-destruct after the Wraith had tampered with the system. He escaped with the survivors in a Jumper and had to wait for over a week until they were rescued by the Daedalus. (SGA: "Midway") He was transferred to the Daedalus and was aboard when the ship engaged a Hive ship. He intercepted a signal and after the battle reported what he had found and it was coded in Wraith language. (SGA: "Enemy at the Gate")
