The Purge

The Purge is the thirty third episode of Ben 10: Ultimate Alien and the first episode of the third season.

Plot
Driscoll, Urian, Enoch and Patrick are all sitting in the same room, saying they are sick of each other and were about to fight until Old George arrives. He scolds them for separating the Forever Knights into different factions but then they fight him but he and his knights stop the four of them and their knights. However, George reveals his identity and they bow before him. Old George united the Forever Knight factions into one and vows to rid the Earth of all aliens.

Pierce, whose identity is hidden by an ID Mask, is trying to flirt with a human girl, but then some Forever Knights come and defeat him. Meanwhile, Ben as NRG, Gwen, and Kevin are fighting Trumbipulor, who has escaped the Null Void. Despite their efforts, he escapes and Argit comes to take his place. He explains that the Forever Knights are trying to make him and other aliens leave the planet, and he needs their help to convince them to stay. Despite their lack of trust in him, they decide to look into his story. Finding a few hundred aliens have indeed "left", they go to a Forever Knight castle to investigate. However, they accidentally activate the castle's security alarm; another robotic dragon.

The group fights the dragon, but it is different than from before. Ben and Kevin use Lodestar and easily destroy the dragon. They head to an alien food market and talk to the butcher Mr. Baumann, who has been hiding an alien family. Soon, the gang round up a bunch of aliens and the supply ship comes, but then some of George's knights arrive and they fight the gang, with Ben as Upchuck leading. However, they end up being outnumbered by the number of knights and get defeated.

Ben, Gwen, and Kevin free themselves from their handcuffs and Ben challenges Driscoll to a duel, going from Spidermonkey to Ultimate Spidermonkey. Though Driscoll was gaining the upper hand, Ben beats him and threatens him in a dark way to free the alien prisoners and get rid of the knights. Driscoll reports his failure to George, but George reassures him that he will not be punished and that this will be the beginning of a war between the humans and the aliens.

Quotes

 * Argit: (shuffling through the Forever Knight relics) Wherever they went, they left some choice stuff behind.
 * Kevin: Leave it Argit. It's not worth the hassle, trust me.
 * Argit: Man, it's like I don't even know you anymore.


 * Ben (to Driscoll): Maybe you forgotten something: I'm Ben Tennyson, who wear the most powerful weapon in the universe. I stopped the Highbreed invasion, I defeated Vilgax in the hand-to-hand combat and I've beaten the Forever Knights more times that I can count. Here what's going to happen: you're going to release this prisoners, you're going to craw back to whatever you came from and you're going to stop hunting down aliens because if you don't, I promise, you'll regret for the rest of your short lives.

Errors

 * Lodestar's back was different than it's supposed to be.


 * Argit's shirt was brown when they pretended to leave the alien market and snuck behind the owner.
 * When Ben's team got hit by Trumbipulor's earthquake. NRG's left leg was colored white instead of black.
 * When all the knight leaders stood up and started to bicker, Enoch's mouth was moving, even though he was wearing a mask.
 * Just like in "Girl Trouble," Lodestar's voice is different, being high-pitched.
