After Grandpa Max disappears, Ben and Gwen decide to finish his last job while searching for him. Magister Labrid, 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, where they encounter a robotic dragon.

Fleeing from the dragon, the group runs into an army of Forever Knights. In the ensuing confrontation, Magister Labrid is killed when he saves Kevin's life, and Kevin joins Ben and Gwen on their search for Max to repay that debt. 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.

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 Kevin'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 Ben offers Alan to come with him, Gwen and Kevin. Alan decides to stay, but 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 Max's RV, 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 and afterward 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 (partly because of Gwen's liking to Mike Morningstar) 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 fight back and drains Mike's power in return, leaving him withered and powerless. 
6 "Max Out" May 17, 2008 106
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 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 an unfocused Null Void warp projector to destroy the Highbreed base. With his last words, he tells Ben to "Take it from here". Then everything, except Ben, Gwen, Kevin and Ken, is sent to the Null Void. 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 107
Ben goes on a date with Julie at the local fair, but it is ruined when a dog-like Galvanic Mechomorph named Ship takes control of the rides and kidnaps Julie. Ben rushes to save her, accidentally revealing his secret to her. Julie, however, finds Ben's secret impressive, and assures him his powers are unique. Ship manages to lead Ben back to his ship, where its wounded owner is trapped. After freeing the Galvanic Mechomorph, it decides to leave Ship with Ben. On their walk home, Ship takes off after a passing truck. After Ship disappears, Ben and Julie walk home, holding hands.

Gwen learns where her powers come from when she meets her alien grandmother Verdona. Verdona offers to take Gwen back to her home planet, where she can learn to fully control her powers. When Gwen refuses, Verdona decides to destroy Gwen's body, releasing the energy being inside. After a short battle, Gwen firmly tells Verdona that she wants to stay on Earth and stay the way she is. Verdona accepts this and leaves, though she promises to check up on Gwen occasionally. 
9 "The Gauntlet" June 14, 2008 109
After Ben stands up to JT and Cash, and making Cash look stupid in the process, the two decide to wreck Kevin's car to repair their reputation. After pushing it down a cliff, the trunk is knocked open, and they make off with a laser-firing glove from a robot the group had defeated the previous night. When Cash puts the glove on, it begins to reform into the original robot around his body, compelling him to fight Ben. Ben is able to overpower Cash as Chromastone, and JT manages to convince Cash to fight the robot's influence, reverting it back into the glove. JT reconciles with Ben and walks away with Cash.

A creature is roaming around an abandoned town, aging everything it touches at an accelerated rate. When Ben, Gwen, and Kevin investigate, they meet Paradox, a scientist from the 1950s who was sucked into the event horizon of his time-travel experiment. Displaced from time and space, Paradox has existed for 100,000 years and is able to move through time at will. However, the same mistake that rendered him ageless created the creature they seek. Ben realizes that the creature is not acting like a monster, but a confused person, and has Paradox take them back to the day of the accident. There, as Humungousaur Ben rescues Paradox's assistant, Hugo, nullifying the creature's existence. In the present, the now old Hugo joins Paradox in exploring time and space.

Kevin arranged a meeting for Ben with the Forever Knights, who need help in slaying a dragon they have kept captive underneath their castle for 1,000 years. Slaying the dragon is the very reason their organization exists. After a failed attempt, in which the dragon appears to be trying to communicate, they track it to a warehouse where its spaceship is being held. Ben fits the dragon with a translator as Spidermonkey so it can speak, and it reveals that it was a mapmaker before being captured. Angry after a millennium of imprisonment, the dragon arms itself to fight back. Ben convinces it to leave peacefully. Though the Knights believe to have lost their purpose, the news that a world full of dragons exists renews their pledge, as does their need to exact revenge on those who allowed it to return home.

To make things right, the duo set out into the Null Void to rescue those they wrongfully imprisoned.

The Incusion Emperor Milleous plans to destroy the Earth for kidnapping his daughter Attea. During their search, Ben uses the untested Alien X form to fix a broken dam.

In the meantime, Kevin and Gwen have to protect Ben while trying to save the Earth. Ben, tired of the fruitless debate, demands to be transformed into another alien which can actually get the job done. He manages to save the Earth with Swampfire, but resolves never to use Alien X again.
