Absolute Power: Part 2 is the twentieth episode of Ben 10: Ultimate Alien.
Following on from the previous episode, Kevin is absorbing Gwen's powers. As he is doing so, she begs him to stop. Still angry with her, Kevin says it's her fault and she could've helped him with her magic. She is able to escape from Kevin by using a spell that has all the arcade's games attack him. When Kevin destroys all the arcade games, Gwen is able to teleport out and meets Ben and Darkstar.
In the jet, Darkstar explains that since Kevin had a taste of Gwen's powers, he would want more, making Gwen the bait in his plan. They land in Los Soledad, where Darkstar shows that he recruited Cooper (who had a growth spurt) to help him with turning Kevin to normal by building a machine that will tap into Darkstar's Dominus Librium piece. This will absorb Kevin's powers and all the powers and abilities he stole and return him to normal. Cooper begins building the machine while Ben tells Gwen that he is the only one who can stop Kevin's rampage, because Paradox told him and he is still reluctant to follow Gwen's plan. Kevin arrives at Gwen's house and when he bangs through the door, he finds Max, fully healed. Max then begins fighting Kevin, briefly gaining the upper hand, but Kevin defeats him and is about to kill him, until his stepfather, Harvey Hackett interferes.
Kevin and Harvey begin arguing, with Kevin claiming Harvey convinced his mother to kick him out, only for Harvey to remind him that he demolished their house with his Osmosian powers when he was eleven years old. Ben comes and finds Kevin. Ben transforms into Big Chill and Big Chill freezes Kevin in ice. After Big Chill transforms back into Ben, Ben tries to apologize to Kevin, but Kevin breaks out of the ice. Ben transforms into Spidermonkey and swings Kevin with a street light, but Kevin returns. Spidermonkey smashes him into the Rust Bucket and Gwen comes out. Kevin drives away Spidermonkey by creating a tornado that sucks him up and leads him to the city. Gwen runs away from Kevin, while Spidermonkey gets himself out of the tornado by webbing himself to a street light and contacts Gwen on the Ultimatrix. Gwen is running away from Kevin, who is following her and is able to drive him away by throwing magenta-colored glowing mana spheres at his face. Gwen jumps on a truck, but Kevin is in front of the road and the truck crashes into him, causing an explosion that alerts Ben into a desperate worry. Gwen and the driver were able to survive by being protected by Gwen's magenta-violet purple shield, but Kevin survives also and Gwen tells the trucker to run. Gwen still tries to talk to Kevin, but his insanity is still preventing that. Gwen attacks Kevin using a lightning spell, but Kevin uses the lightning as fuel for his Chromastone powers. As Kevin was going to absorb the rest of Gwen's magical and Anodite powers, Spidermonkey comes and transforms into Echo Echo to fight.
Kevin seemingly kills all the Echo Echo clones and starts absorbing Gwen's powers again, but he is hit by a laser blast from Julie and Ship. Julie brings Gwen into Ship and they begin flying to Los Soledad, where Kevin follows them. Luckily, Echo Echo was able to survive by having one of his clones stay inside the trunk of his car.
Meanwhile, Cooper and Darkstar are almost done building the machine, and Gwen calls Cooper to warn them that Kevin's coming. Cooper thinks of a plan to distract Kevin by taking control of Los Soledad's missile silos, firing the missiles at Kevin. But Kevin destroys all the missiles, surviving the ones that hit him and walks toward Gwen, having enough. When Cooper tries to stop Kevin from hurting Gwen, Kevin attempts to kill Cooper in the process. However, Echo Echo transforms into Ultimate Echo Echo and manages to save Cooper, then he whispers something into Cooper's ear and he runs off. Kevin finally says he had enough of Ben always besting him, and tries to kill him by throwing metal at him, but Ultimate Echo Echo destroys it all and finally defeats Kevin, but tries to end Kevin in angered retaliation. After Ultimate Echo Echo transforms back into normal, Gwen convinces Ben that they can cure Kevin and he is hooked up to the machine. Cooper turns on the machine and Kevin's powers are transferred to the Dominus Librium piece, finally returning Kevin to normal. But there's still bad news, as Darkstar absorbed all the power the Dominus Librium piece took, and becomes all-powerful; however, Ben knew of Darkstar's plan from the start and presses a button that strips him of his powers.
Kevin, who's now sane once again, punches Darkstar and thanks Cooper for changing him back. Gwen gives Cooper a kiss on the cheek for making Kevin normal again and Kevin asks for a kiss from Gwen, reminding her that he's her boyfriend. They kiss and Max and Julie explain that all the power Kevin stole from everyone else returns and that Bivalvan, Galapagus, P'andor, Andreas and Ra'ad have returned to life. Kevin apologizes to Ben, but then they argue and Gwen breaks the argument so Ben and Kevin can help explain to her folks what happened to their house, but instead they ignore her and go to Mr. Smoothy.
