Chief of the Genii
|Out of universe information|
- "Ladon here has only the best interests of the Genii at heart."
Formerly Cowen's chief scientist, he was included in Commander Acastus Kolya's strike team against Atlantis. Radim quickly got the hang of the Lantean technology including the sensors which he used to guide the teams after Major John Sheppard. When Kolya requested reinforcements, he was knocked unconscious by Sheppard who raised the Stargate shield, killing 55 men. Later, he was one of the few able to evacuate through the Stargate. (ATL: "The Storm", "The Eye")
After the failure of the Atlantis mission, Commander Acastus Kolya began plotting to overthrow Cowen and took Radim into his confidence. Radim, feeling that neither Cowen or Kolya was qualified to lead the Genii, betrayed Kolya's information to Cowen, forcing him to go underground, while beginning to plot against Cowen. In an elaborate triple cross, he offered a Zero Point Module (which was depleted) to the Atlantis expedition, in exchange for supplies for his "rebellion" against Cowen. Ladon's sister Dahlia Radim and a team went to get the supplies, while Lt. Colonel John Sheppard and Dr. Rodney McKay went to get the ZPM. Sheppard, McKay, and a group of soldiers were captured by Cowen, who thought that Ladon was still working for him. Cowen demanded the expedition's Puddle Jumpers, and revealed that Dahlia and the others of her team were dying from radiation poisoning. Ladon intended to detonate the Genii A-bomb killing the soldiers and Cowen, but when he learned that they could save his sister's life, he freed them, allowing the weapon to go off and kill Cowen. He then returned to the Genii homeworld and assumed power. (ATL: "Coup D'etat")
When Commander Acastus Kolya heard of this, he felt that Radim had stolen what was rightfully his. He captured Lt. Colonel John Sheppard, using a captive Wraith to feed on him, demanding Ladon in return. Dr. Rodney McKay and Ronon Dex were willing to turn Ladon over, but Ladon eventually discovered the Stargate address that they were being held in. (ATL: "Common Ground")
When some of the Lanteans aboard the Tria came back to reclaim the Atlantis and relocated the Athosians to New Athos, he asked Teyla Emmagan and Ronon Dex to join him and the Genii in their fight against the Wraith. (ATL: "The Return, Part 1")
