In the "I Am Number Four: Lost Files: The Search for Sam", it is revealed that the General and Ivanick covered up Adamus' betrayal and made it look like he died by the hands of Three. Ivanick was promoted and was stationed at the government base in New Mexico. Ivan meets up with Adam, who has completely sided with the Garde and now has powers, and a battle emerges. Ivanick is killed by Adamus, who caused an earthquake to happen, which results in rubble collapsing on Ivan's head, beheading him. Kelly is the daughter of the General. Anu was a Mogadorian doctor who created a machine that would let the user see a dead Garde's memories. Adamus is the first one to use this machine to see Number One's memories. Anu had bet his life that the machine would work, but due to the supposed failure of the machine since Adamus did not wake up from his coma, he was killed by the General. Adamus' mother later reveals that the General never liked Anu and was surprised that he wasn't killed earlier. Rexicus Saturnus is a young Mogadorian commander, who appears in "The Forgotten Ones". After the events of "The Search for Sam", Rex survives the collapse of the New Mexico underground base and meets up with Adam, who helps him to the surface and find shelter. During their time of recovering from the incident, Rex realizes who Adam is and desires to kill Adam for his betrayal, despite that he saved him. After providing information that the Mogs are attempting to harness the Chimæra shapeshifting gene and adding it to their Vatborn soldiers from the captured chimæras who are being held at the main facility on plum Island, Adam forces him to take them all the way to the main research facility in Palm Island, New York. While Rex does want to kill Adam, he also forms a small friendship with him and begins to like him. After an attack from the Mogs and hiding during the battle, Rex rescues Adam in the aftermath and takes him to Palm Island. When Adam asks why he hasn't killed or betrayed him, Rex replies that he doesn't know and that he wants to fulfill his promise. Coming up with a plan, Rex pretends to take Adam as a prisoner and infiltrates the facility. Later on, he breaks him out and they find the Chimæra, setting them free. After saving the Chimæra and making sure that Adam is free to escape, he stays behind, still believing in the Mog Cause and hoping to rejoin his fellow Mogadorians.
