After ambushing Ben at his house, Ra'ad (the fifth and last of the aliens captured by Aggregor) blames him for letting Aggregor recapture the other four aliens. Aggregor has been tracking them through the Ultimatrix each time it scans one of them. While trying to resist being scanned by the Ultimatrix, Ra'ad causes it to malfunction, and ends up deactivating it while both his and Ben's consciousnesses end up trapped within the same body. Despite Ra'ad's protests, Gwen and Kevin reactivate the Ultimatrix, and separate them. In doing so, they alert Aggregor to their location. Ra'ad flees, leaving the others to be wiped out by the Osmosian. After Kevin scolds Ra'ad for his cowardice, the alien decides to surrender himself to save Ben, and is recaptured by Aggregor. After the battle, Ben swears that he will do whatever it takes to save the captured aliens.
