Unaware that Ra'ad was also trapped in the Ultimatrix and manipulated the device to allow Ben to only transform into AmpFibian, so Ben transform into his Amperi form to battle Aggregor, but Aggregor suddue AmpFibian and decided to take him instead of Ra'ad. Gwen used her magic transport her, Kevin and AmpFibian away from Aggregor. Kevin rebuilt the machine he once used to hack the Omnitrix in Vengeance of Vilgax: Part 1, to reactive the Ultimatrix so AmpFibian can revere back into Ben. Ben soon realised that Ra'ad is fused with him in his AmpFibian form and plans to take over him along the his Ultimatrix to prevent Aggregor from finding with it's energy signal. Ra'ad soon take control of AmpFibian and tries to attack Kevin and Gwen, but Gwen trapped him in her Mana force-field, and Kevin absorb rubbler to project him from AmpFibian's electric attacks and used the machine to reboot the Ultimatrix, and transforming AmpFibian back into Ben and separate Ra'ad from AmpFibian's DNA.
