leaving ben with only Swampfire, Humungousaur, Cannonbolt, Big Chill, and Spidermonkey.
When Vilgax Attacks ben force alien invades the Earth using a Null Void projector (which beams Null Void prisoners to Earth),
ben, Gwen, and Kevin, snap into action to defend their hometown Bellwood from the attacks.
Splitting up, ben battles Vilgax's servant Psyphon, who brings a Mr. Smoothy billboard to life to attack ben.
Gwen and Kevin show up, along with Professor Paradox, who teleports the gang back to the past to stop Vilgax's plan before it happens.
Paradox gives the trio a message from Grandpa Max, who directs them to the planet Vulpin, home of Wildmutt, one of ben's original aliens.
ben calls upon the Galvanic Mechomorph Ship to aid them.
On Vulpin, another message from Grandpa Max reveals that Vilgax is using the planet's refinery to create a piece of alien tech for an unknown purpose.
ben heads off to the refinery alone; along the way, he battles several of Vilgax's robots, some Vulpimancers, and a giant two-headed snake.
When he reaches the refinery, he encounters the Vreedle Brothers (Octagon and Rhomboid Vreedle) and defeats them, and destroys the alien tech,
setting fire to the refinery in the process.
He reunites with his teammates, who learn of Vilgax Attacks ben force alien's plan: find an energy core to energize his Null Void projector and use it to take over Earth.
In another message, Maxs directs the team to Terradino, which is Humungousaur's home planet.
The group arrives at Terradino and learns that the next energy core is located in a nearby temple.
ben gets Goop back and inside the temple, he ends up facing Charmcaster, who wants revenge on ben for his actions against her Uncle Hex.
Ultimately, Charmcaster is defeated, ben destroys the energy core, and the temple begins to crumble.
ben meets back up with Gwen and Kevin, and they learn that Max has gone to Encephalonus IV,
Brainstorm's home planet, where an old enemy of ben's is waiting for him.
