Ben is now facing both a revived Ghostfreak and Doctor Vicktor, quickly transforming into Grey Matter to escape. Grey Matter is able to discern Ghostfreak's plan from a computer terminal: Using the corrodium to amplify the power source of the orbiting space station, in conjunction with the device the alien werewolf built in New Mexico, Ghostfreak is intent on covering the daylight side of the Earth in a corrodium shield. This will not only mutate Earth's population, but it will also block out the sun, giving Ghostfreak a world of eternal darkness to rule over. Ben uses Upgrade to create a makeshift rocket to get to the space station, which Vicktor clings to so that he might also get to the station. Meanwhile, Max and Gwen fight the mummy aboard the space center and attempt to thwart Ghostfreak's plan from there.
Upgrade seemingly defeats the mummy, but Ghostfreak appears again and manually starts the device. In pure darkness, Ghostfreak's form enhances; Ben's new Benvicktor form holds him off until Doctor Vicktor returns. However, Max tricks Vicktor into destroying the projector, ruining Ghostfreak's plan and apparently killing the werewolf. In a fit of rage, Vicktor attempts to warp Ben away, but accidentally banishes himself and the mummy. Ben and Gwen escape with Max on the shuttle, on which they again expose Ghostfreak to sunlight and defeat him. Cannonbolt protects Gwen and Max from atmospheric reentry, and the three land in Egypt. In the aftermath of the attack, Ben realizes that he has regained Ghostfreak's natural form on the Omnitrix.
