But Kevin brought some plant-like aliens with him (apparently from Wildvine's homeworld) and they begin joining the rampage as well. While heading to San Francisco for a real vacation, Kevin 11 shows up from a Null Void portal on the Golden Gate Bridge, and begins going on a rampage with Ben tracking him down. After defeating Enoch, his robot expels another crystal and Ben regains Cannonbolt from it. The Tennysons track Enoch to the Hoover Dam and fight him and his robot. At Area 51, Ben fights Enoch, but he escapes with a giant robot made in his own image, using technology from the base. After fighting the Forever Knights at the Mesa Verde, one of them tells the Tennysons that Enoch is using technology from Area 51 to stop a dangerous threat. The Tennysons see that the Mechadroids and the Forever Knights are fighting each other. After fighting most of the robots, Ben fights a giant robot, and after defeating it, it expels a crystal (referred to as Omnitrix Crystals) and by absorbing it into the Omnitrix, he is now able to change into XLR8. Strangely, Ben can only change into Four Arms and Heatblast. Ben wakes up to see a large object crashing into the canyon, releasing some of Vilgax's Mechadroids. While sleeping near the Grand Canyon, a mosquito-like drone begins absorbing DNA from Ben's Omnitrix.
