1 "Ben 10 Returns: Part 1"
1 "Ben 10 Returns: Part 1"  April 18, 2008 101 After Grandpa Max disappears, Ben and Gwen decide to finish his last job while searching for him. Magister, Max's alien partner, guides them to an arms trade between the Forever Knights and the DNAliens, brokered by Kevin Levin. Kevin is captured, but the Forever Knights escape with one of the weapons crates. Kevin, having not been paid, leads them to the Forever Knights' hideout. In the ensuing confrontation, Magister is killed when he saves Kevin's life, and Kevin joins Ben and Gwen on their search for Max to repay that debt.  2 "Ben 10 Returns: Part 2"  April 18, 2008 102 After Ben, Gwen and Kevin track the weapons to a secret underground base, they discover an army of aliens, led by the Highbreed commander. Annoyed at being discovered, the Highbreed commander orders the termination of all life within a five-mile radius to eliminate any witnesses. In Ben's successful efforts to stop the commander, he learns that any damage he receives while transformed is inflicted upon his human form as well.  3 "Everybody Talks About the Weather"  April 26, 2008 103 The authorities arrest a half-human, half-Pyronite boy named Alan for arson and criminal damage. Alan is wearing a Plumber's badge, which the local sheriff triggers when he confiscates it. The badge signals Magister's badge, which leads Ben, Kevin and Gwen to Alan. After a battle with Alan, Ben discovers that the DNAliens are responsible for the damage, having built a weather machine in the field. With Alan's help, Ben destroys the machine, and afterwards Alan offers to aid them whenever they need it.  4 "Kevin's Big Score"  May 3, 2008 104 Just when Ben and Gwen start to trust Kevin, he runs off with the Rustbucket in hopes of trading it for alien technology. However, he is double crossed by one of his old contacts and the Rustbucket is stolen. Before he can get it back, it is stripped for parts. Having been told that Vulkanus, who he had double crossed years ago, is in possession of the alien device he seeks, Kevin tries to make a deal. Still bitter, Vulkanus has Kevin absorb a rare alien crystal, planning to use him as a living gem mine. He is rescued by Ben and Gwen. He reveals that the item he sought is a holo-viewer with another message from Grandpa Max, telling Ben that he will need to recruit a team.  5 "All That Glitters"  May 10, 2008 105 Ben, Gwen, and Kevin set out to locate the other Plumbers to recruit new members, and the first one on their list is a boy named Mike Morningstar. While Ben and Gwen are quick to trust him, Kevin remains suspicious, particularly after they are attacked by a group of zombified school girls at the local power plant. Kevin's suspicions turn out to be valid, as it is Mike who is making the zombies, draining them of their lifeforce then commanding them to collect more power for him. When he does this to Gwen, he becomes nearly unstoppable, but Gwen is able to come to her senses and drain Mike's power in return, leaving him withered and powerless.  6 "Max Out"  May 17, 2008 107 Gwen's older brother, Ken, is missing and Gwen asks for Ben and Kevin's help to find him. In their search, the gang stumbles upon a Highbreed base that manufactures Xenocytes: facehugger-like parasites that mutate humans into DNAliens. Ken has been infected by one of the Xenocytes, but Ben is able to remove it with the help of the now-talking Omnitrix. With Ken in tow, the gang finds Grandpa Max inside in the base. He explains that the Xenocyte eggs will be shipped across the country, and asks the gang to destroy them. While they comply, he sets about destroying the factory while searching for the egg-laying machine. The gang finds Max locked in battle with a Highbreed commander upon their return. In an act of self-sacrifice, Max uses a unfocused Null Void warp projector to destroy the Highbreed base. With his last words, he tells Ben to "Take it from here". In the aftermath, a group of disguised DNAliens are shown gathering surviving Xenocytes from the wreckage of the base.  7 "Pier Pressure"  May 31, 2008 106 Ben goes on a date with Julie, but it is ruined when an alien named Ship makes trouble at the local fair.  8 "Be-Knighted"  108 The Forever Knights secure a weapon in the hopes of aiding them in slaying a dragon they hold captive.  9 "What Are Little Girls Made Of?"  109 When Ben and Gwen learn that their grandmother is an alien, Gwen must make a difficult decision.  10 "The Gauntlet"  110 Cash and JT steal a gauntlet from Kevin's car and decide to use it against Ben, but an evil spirit within the glove possesses Cash instead.  11 "Plumber's Helpers"  111 Rogue young Plumbers assume that Ben and his team are dangerous.  12 "Paradox"  112 A time-traveling experiment from the 1950s sends a monster to Ben's time.  13 "X Equals Ben Plus 2"  113 An alien emperor plans to destroy the Earth for kidnapping his daughter. In order to save the planet, Ben must uncover the secret of Alien X.  April 18, 2008 101 After Grandpa Max disappears, Ben and Gwen decide to finish his last job while searching for him.
