Ronon Dex

Ronon Dex is a fictional character in the 2004 science fiction television series Stargate Atlantis. Played by Jason Momoa. The storyline is about Ronon who is from Sateda. Sateda is a civilization which was at a technological level comparable to Earth in the mid-20th century before it was devastated by the Wraith alongside all other advanced civilizations in the Pegasus galaxy. When Ronon Dex and the Atlantis expedition first met in the season 2 episode "Runner", Ronon Dex had been a Runner for the past seven years. He joined the Atlantis Expedition shortly afterward, effectively replacing Aiden Ford on Sheppard's team after Ford had become addicted to a Wraith enzyme and had fled Atlantis.

Jason Momoa, along with some of his fellow cast members, said that they think of Ronon as the Atlantis version of Chewbacca. This joke was also carried through into the show, as Lt Col Sheppard occasionally refers to Ronon as "Chewy."
