Ratchet & Clank
After meeting Captain Qwark in Blackwater City, Ratchet and Clank visited Umbris in hopes of joining Qwark in his battle with Chairman Drek. However, after braving the captain's hazardous obstacle course, Qwark revealed that he is Drek's spokesperson and left Ratchet and Clank to be killed by his Blargian Snagglebeast. Following the Snagglebeast's defeat, Ratchet became furious with Clank for falling for Qwark's lie and swore to get payback on the superhero. However, after seeing a sergeant in trouble through an Infobot, Clank convinced Ratchet to help him out by reminding Ratchet that he needed Clanks robotic ignition system to leave. They took a ship left by Qwark and headed for Batalia.
