Fused is the eighth episode of Ben 10: Ultimate Alien.

Original Airdate

June 11, 2010


While patroling, Ben falls asleep after going four nights a row without any sleep. After Kevin and Gwen drop him off at his house, Ben can't get rid of the feeling that something is following him.

While sleeping, lightning goes through the electrical lines of Ben's house and then suddenly, Ra'ad, the last of Aggregor's prisoners, shows up and attacks him. He changes into Jetray to fight him. The battle ends when Ra'ad falls into a pool while charged up and shorts out. Ben, Gwen, and Kevin then take Ra'ad to Los Soladad where they have him in a containment cell. Ra'ad tells Ben that it's his fault that Aggregor recaptured his friends (the other four prisoners). Ra'ad confirms that Aggregor is indeed an Osmosian like Kevin, and tells the trio that with the combined powers of himself, Bivalvan, Galapagus, P'andor, and Andreas, Aggregor would be the most powerful being in the galaxy. Ben offers to have Ra'ad work together with them to stop Aggregor. The Amperi seems to agree with the deal, but the moment that Ben releases him, he attacks the trio, having read Kevin's mind that if things got worse, he would hand Ra'ad over to Aggregor. At that moment, the Ultimatrix detects that Ra'ad's DNA is uncataloged. Ra'ad states that Aggregor used Ben's Ultimatrix as a homing device to track the aliens and bypassed his calls to the Plumbers. To prevent Aggregor from finding him, he tries to destroy the Ultimatrix with a lightning blast, but it launches its scanning wave at the same time. The mixing energies cause an explosion which blasts Ben into the wall and damages the Ultimatrix while Ra'ad has mysteriously disappeared. As Ben laments that things can't get worse, Aggregor shows up to recapture Ra'ad.

Ben and his team try to fight Aggregor, but he proves to be too strong for them. The Ultimatrix finally lets Ben access a form, but unfortunately, all that he can transform into is Ra'ad. With no choice, Ben turns into Ampfibian and fights Aggregor. Unfortunately, he's still too powerful and decides to use Ben in his Amperi form as Ra'ad's replacement. Gwen then casts an unusually powerful unnamed teleportation spell to transport her, Ben, and Kevin away from Aggregor to Kevin's warehouse. As Gwen recovers from her teleportation spell, Kevin has revealed he rebuilt the machine they had used to try to hack the Omnitrix during Vengence of Vilgax to reboot the Ultimatrix and change Ben back to normal, since he is stuck in the Ampfibian form, although Gwen and Ben protest the idea. Suddenly, Ben begins hearing Ra'ad's voice inside his head and begins acting like him. It turns out that the blast back in Los Solodad accidently trapped Ra'ad inside the Ultimatrix. He refuses to allow the Ultimatrix to be reactivated because Aggregor would find them. At the same time. he's slowly taking over Ben's body

While Gwen holds Ampfibian/Ra'ad inside an energy sphere, Kevin absorbs a rubber tire to enable him to get near Ampfibian and use jumper cables attached to the machine to reboot the Ultimatrix. This time, the plan is a success, Ben and Ra'ad are separated and Kevin remains unmutated. Unfortunately, with the Ultimatrix's signal restored, Aggregor is free to find them. Rejecting Ben's offer to fight together, Ra'ad quickly escapes as Aggregor crashes in through the roof. After dispatching Kevin and Gwen, Aggregor demands Ra'ad from Ben, who tries to fight him using Brainstorm, but Aggregor's weapon easily defeats him since it's used to handle all electrical aliens. Aggregor then tries to forcibly change him back into Ampfibian by using his weapon on the Ultimatrix faceplate. Outside, Kevin(who was thrown there by Aggregor) sees Ra'ad and yells at him about letting the only person who wanted to help him die. Ra'ad attacks Aggregor and saves Ben. Ra'ad tells Ben and Gwen to get out while he clashes with Aggregor. In the midst of the battle, Kevin's warehouse explodes for the second time, but Ben and Gwen manage to escape while Aggregor takes Ra'ad back to his ship in the middle of the blast. Now that Aggregor has all five of his prisoners again, he is now able to resume transporting them to his home planet and carry out his plan of permanently absorb all of their powers and abilities and make himself invincible. Kevin and Gwen believe it is all over, but Ben tells them that he plans to use the powers and abilities of his new aliens to save the prisoners and stop Aggregor once and for all.
