X = Ben + 2

X = Ben + 2 is the thirteenth episode of the first season of Ben 10: Alien Force, and the thirteenth episode overall.
==Synopsis==
The Incurseans blame Earth for the kidnapping of Emperor Milleous' daughter, Attea. Raff, the Emperor's right-hand man, recruits Kevin to help them recover Attea before the Emperor uses the Conquest Ray to destroy the Earth. Ben transforms into Alien X but soon discovers his powers are too great to control. Ben must gain control over Alien X before Emperor Milleous can use the Conquest Ray to blow up Earth.
==Plot==
A starship docks with an Incursean cruiser, dropping an Incursean named Frolic off. He stops to talk to Raff, one of the commanders. He explains that when they were exploring an enemy star system, they were ambushed by the bounty hunter SevenSeven and Princess Attea went missing. They report to Emperor Milleous, and he kills Frolic, sending Raff to the nearest inhabited planet: Earth.
Ben, Gwen, and Kevin are arguing in the latter's car about where to go. Several Incurseans then appear and point their guns at the three, but Raff appears and stops them, as Kevin reveals he used to do business with Raff back when Kevin was a villain. Raff explains the situation to Kevin and Ben's team. Ben's team agrees to help after Milleous threatens to blow Earth to pieces with the Incursean Conquest Ray. Gwen uses a piece of Attea's clothing to track her to a dam.
SevenSeven destroys the dam while trying to shoot Attea and it crushes Kevin's car, traps Gwen in a bubble and nearly drowns SevenSeven, Attea, and Kevin. Ben decides to transform into an untested Celestialsapien transformation named Alien X to stop the water and fix the dam. However, SevenSeven snatches Attea and Alien X is frozen in place. Ben soon realizes that in order for Alien X to do anything, he must convince one of the two personalities, Bellicus, the voice of rage and aggression and Serena, the voice of love and compassion, to agree with him.
Raff teleports Gwen and Kevin, along with the Incurseans and Kevin's car to Milleous. Milleous destroys Pluto to demonstrate the Conquest Ray's power. Even worse, Ben finds out that Bellicus and Serena do not want him to change back. Kevin absorbs his car's tires and takes the Royal Detonator and flees from battle. Ben makes Bellicus and Serena agree on saving the Earth but is unable to convince them on what to do. Gwen and Kevin get away from the Incurseans chasing them and run into Attea and SevenSeven. SevenSeven releases Attea, but it's revealed Attea paid SevenSeven twice as much to overthrow Milleous.
Attea takes the Conquest Ray and imprisons Milleous, Gwen, Kevin and Alien X. When Ben sees this, he forces Bellicus and Serena to release him from Alien X's body. Before Attea can fire the Conquest Ray, Ben transforms into Swampfire and defeats SevenSeven and the Incurseans, before Milleous arrives and forces Attea to surrender.
Attea is thrown in stasis jail with her mother and Milleous lets Ben's team return to Earth without destroying the planet. Ben makes a vow never to turn into Alien X again, despite all the power he possesses.

==Trivia==
* The episode's title is listed as X Equals Ben Plus 2 at the back of the Ben 10 Alien Force: Volume 3 DVD, as well as the Cartoon Network website.
* It is unknown who hired SevenSeven to capture Attea.
*The crew did not know that Cartoon Network considered this episode to be the Season 1 finale until they saw the ads on TV. The first 26 episodes were conceived and produced as one season.
*The action sequence at the dam was storyboarded by LeSean Thomas.
*This episode is Matt Wayne and Derrick J. Wyatt's favorite episode of Alien Force. 
**Matt stated that it was fun to write the interior scenes and really enjoyed the "goofy action stuff" with Gwen and Kevin driving the car around the Incursean ship, trying to get away from the Incurseans, while Alien X was immobile in the trunk. He has always thought that if the episode hadn't been promoted as a life-changing revelation, it would have been received as the fun, quirky episode it was supposed to be.
