Chuck

"There is no Chet!"

- Chuck on Richard Woolsey's poor knowledge of Atlantis' staff.

Chuck is a Canadian member of the Atlantis expedition, holding the rank of Sergeant. He was part of the original expedition team that departed from Earth in 2004, and has since served as a technician in Atlantis' control room. He was usually seen in the background of the control room, but following Peter Grodin's death, he took over the running of the Stargate, usually informing Weir of an incoming wormhole or an unscheduled off-world activation. He later begins sharing this duty with fellow tech Amelia Banks.

2005
When a piece of technology in Stargate Operations began malfunctioning, he called Dr. Radek Zelenka to find the problem. It turned out that to be the Long range sensors detecting three Wraith Hive Ships.

Chuck mans one of the control stations as McKay, Miller and Peter Grodin attempt to use the Lagrangian Point satellite to destroy the three hive ships. When Grodin destroys one with the weapon, Chuck cheers with everyone else, but is left somber by the news of Grodin's death. At Weir's signal, Chuck activates the PA system for Weir to inform the entire city of the development.

During the Battle of Atlantis, he manned the sensors and coordinated the strike teams in search of the Wraith that had beamed into the city. When Sheppard destroyed one of the hive ships, Chuck somberly reported it to Weir, McKay and Beckett before unexpectedly picking up the arrival of another ship on sensors, one that was broadcasting an IFF. To everyone's relief, the ship is revealed to be the Daedalus which had rescued Sheppard. As the Daedalus fights it out with the Wraith, Chuck informs Weir that he has lost contact with three of the Wraith hunting teams and then reports when the destruction of the last hive ship by the Daedalus.

When Lt. Colonel John Sheppard's team discovered the Doranda outpost, he transferred data from the outpost to Dr. Rodney McKay's lab.

A few months later, he was in the process of dialing Earth when McKay received the message from the Daedalus that there was a bomb in Atlantis. Fortunately McKay was able to stop him before he finished dialing.

2006
When Lt. Colonel John Sheppard and Dr. Elizabeth Weir were taken control over by alien consciousness's, he helped coordinate the search teams.

When Michael Kenmore returned to Atlantis with his Hive Ship to form an alliance with the Atlantis expedition, he received the data on the Wraith Hive Ship and downloaded it.

When Dr. Daniel Jackson, Dr. Elizabeth Weir, and Vala Mal Doran were using the Holo room, he determined they were using no power, proving it was Morgan Le Fay using the hologram.

2007
When Atlantis was stranded in space after the Asuran satellite attack, he was assigned to repair the Subspace communications by Dr. Rodney McKay.

When Todd arrived on Atlantis, he detected the Wraith Hive Ship that was headed toward Atlantis.

2008
He was in Stargate Operations when a quarantine lockdown was imposed by an ionospheric storm the previous night. Before the city's self-destruct was activated by a supposed breach, he tried but failed to shut down the cities Subspace communications.

When Teal'c and Ronon Dex were sparring in the Atlantis gym, he was seen placing bets on the outcome. When Colonel Samantha Carter stopped the fight, Lt. Colonel John Sheppard took his money back.

When a Daedalus from an alternate reality appeared in orbit above Atlantis, he detected it with the sensors. Later, he contacted Earth and informed Lt. Colonel John Sheppard that the real Daedalus was in the Milky Way.

He detected the Vanir spaceship's hyperdrive signature and contacted Lt. Colonel John Sheppard in his quarters by patching into the PA system.

When Shen Xiaoyi came to evaluate Richard Woolsey, he attempted to impress her by being able to name the staff in Stargate Operations but incorrectly referred to him as Chet; he quickly tried to cover himself by saying "Chet" worked the nightshifts. After Woolsey left Stargate Operations Chuck said "There is no Chet!".

Shortly before he notices the approach of the Vanir spaceship, he is seen in a relaxed pose, his feet resting on the console and reading a book about World War II fighter aircraft. This happens during the night which might imply that he actually is also partly working the night-shifts, or at least this particular one. When the Vanir ship passes through the Atlantis shield, Chuck is shocked and confused by this occurrence.

2009
After Atlantis was finally allowed to leave Earth again, Sheppard asked Chuck to call McKay for him. Chuck agreed to do so, but informed Sheppard that he would not be returning to Pegasus as his mother was sick with cancer. Sheppard wished Chuck luck and hoped to possibly see him again in the future as a member of the expedition.

Behind the scenes

 * Though his character has appeared in dozens of episodes since the first season of Stargate: Atlantis and in one episode of Stargate SG-1, Chuck's full name has yet to be identified on screen; the episode credits originally listed him only as "Technician"; by the end of season three it's changed to "Chuck". However, Dr. Elizabeth Weir addressed him as "Sergeant" in "Trinity". In "First Strike" Torri Higginson accidentally called the actor by name and the producers kept it in, thus giving the character a name. In "Remnants", Richard Woolsey mistakenly calls him Chet, which Chuck corrects him, then gets exasperated when Woolsey believes there is a Chet somewhere on-base when there is no one by that name.
 * Along with John Sheppard, Rodney McKay, Elizabeth Weir, Teyla Emmagan, Samantha Carter, Radek Zelenka and Walter Harriman, he is one of only eight characters to appear in all five seasons of Stargate: Atlantis. However, Carson Beckett appears in Season One to Three while his clone appears in Seasons Four and Five.
