1 "Darkstar Rising" October 10, 2008 201
Ben, Gwen, and Kevin are forbidden to fight against the Highbreed threat by Magister Prior Ghilhil of the Plumbers, who doubts the Highbreed are even as much of a threat as they claim. However, all three sides find themselves working together when Mike Morningstar, now going by Darkstar, captures all but Gwen to feed his powers. With the help of the DNAliens, Gwen frees her friends and Mike is captured while the Highbreed Lord and the DNAliens escape. In gratitude, Magister Ghilhil makes the team Honorary Plumbers so they can defend the Earth legally and help the world. 
2 "Alone Together" October 17, 2008 202
After an accident with a teleporter pod, Ben and a Highbreed Commander named Reinrassic III are stranded on a desert planet that acts as a routing station for the teleporter. The pair are forced to work together to fend off the dangerous predators on the planet while making their way to the routing station, much to Reinrassic's chagrin. As they make their way across the desert, the two save each other from danger several times, even risking their own lives to do so. After reaching the teleporter pod, Reinrassic III stays behind, having deemed himself contaminated by Ben and thus a risk to the purity of his species. 
3 "Good Copy, Bad Copy" October 24, 2008 203
A Galvan (the race that created the Omnitrix and gave Ben the form of Grey Matter) named Albedo builds his own Omnitrix and is permanently stuck in Ben's human form (since wearing the Omnitrix, Ben's DNA has become a default in the Omnitrix, according to Albedo). Now, because they share DNA, they can change into the same forms as each other. Azmuth comes after both Ben and Albedo's Omnitrixes become attached, permanently damaging Albedo's human form. Azmuth removes the face plate of Albedo's Omnitrix, ensuring his human form is both a punishment and a prison for proving himself as a lesser being. Albedo is teleported to a Plumber prison while Azmuth says to Ben that he was the one to use the Omnitrix for good, not evil. 
4 "Save the Last Dance" November 7, 2008 204
Gwen forces Kevin to take her to her school's dance, forcing a clueless Kevin to seek advice from Ben. However, Ben has his own problems, as Big Chill takes over his body with each transformation and starts trying to eat every metal object in sight. Joined by Julie, Gwen and Kevin manage to subdue Big Chill, only to discover that Big Chill was only building a nest for eggs he had laid. The eggs hatch into infant Necrofriggians, and Kevin teases Ben about being a "mother." Julie takes Ben home on her scooter, while Gwen and Kevin miss the dance, and decide to dance to the music in Kevin's car. 
5 "Undercover" November 14, 2008 205
Kevin, Gwen, and Ben destroy a teleporter they were working on and need help repairing it. Kevin suggests Cooper, the young boy who had helped the Tennysons in the past (who also happens to have a huge crush on Gwen). Unfortunately, Cooper has been kidnapped by the DNAliens. They track him to the abandoned military base where Paradox built his time machine. They discover that the Highbreed have erected a cloaking field, built by Cooper over the area, concealing a mysterious arch-like device. They free Cooper and have him destroy the cloaking generator, during which he has visions of the arch acting as a gateway for a fleet of ships and the Earth being destroyed. Despite destroying the generator, the Highbreed manage to repair it and continue their operations unhindered.

Forever Knights' scientist Dr. Joseph Chadwick sends Sir Morton to kidnap Ship so that the Forever Knights can use him to mass-produce a fleet of interstellar spacecraft with which to attack the homeworld of the alien dragon that escaped them. Joined by Julie, who has been taking care of Ship, Ben, Gwen, and Kevin mount a raid on the Forever Knights' stronghold to rescue him. Though Joseph is using a control device to make Ship obey him, Julie is able to convince Ship to resist. The Forever Knights' stronghold is destroyed and the group now has access to a spaceship since Ship can transform into the vehicle the Forever Knights had hoped to mass-produce.

Kevin's trouble with the DNAliens eventually pushes Ben over the edge, and he breaks out of his house as Humongousaur in front of his parents to help.

Helen and Manny call on Ben to help deal with a dangerous foe in the Null Void: D'Void. Ben goes in alone, with Kevin and Gwen waiting on the other side to bring him back.

Using them as slave labor, he has built a machine to drill through the dimensional wall, hoping to bring his army to Earth. With the help of Grandpa Max, who was transported to the Null Void in "Max Out", and a small force of rebels he has gathered, Ben manages to destroy the drilling machine as Big Chill and defeat Dr. Animo.

More DNAliens arrive to reclaim the Oscillator Key, capturing Tyler during the struggle.
