Chapter 1: So Long, Earth

In the town of Bellwood, an orange space ship had begun to descend after returning from a summer long, galactic road trip. As it approached the ground, the ship transformed into a similarly colored plumber's truck with a logo that read "Max's Plumbing" on each side. The trucked parked on the side of the road and the passenger seat door opened, revealing the savior of the universe and bearer of the Omnitrix, Ben Tennyson, or Ben 10.

Stepping out of the truck, Ben pulled a black and green backpack out with him as he disembarked. "Are you sure you do not want me to drop you off at your house?" Ben's partner, Rook Blonko, asked from the driver's seat.

"Nah," Ben replied, "I kind of want to what around town to see the sighs after being gone for so long."

Rook smiled as he said, "Then I will see you tomorrow for patrol, partner."

"You too, dude."

Having said their goodbyes for the day, Ben began his tread through Bellwood while Rook drove off to return to his quarters at the Plumber Base in orbit around Earth. A few minutes into his walk, Ben noticed a plume of smoke coming from Mr. Baumann's shop. "This can't be good," Ben said to himself as he hurried over to the store.

When he got to the store front, Ben noticed several alien cars parked haphazardly just outside the store. "This is Ben Tennyson to Plumber Base," Ben said into his Omnitrix on his left wrist, "requesting back-up at Baumann's store. Over." Ben ran through the entrance of the store and found it flooded with alien criminals. At the counter overlooking Mr. Baumann was the gang leader, Psyphon. Seeing that Mr. Baumann was in trouble, Ben called out, "Mr. Baumann, don't worry, I'll take care of this."

Psyphon heard Ben's calls to the shop owner and directed his attention at the galaxy renowned hero. "I knew you would come here if we created a commotion," Psyphon said.

"Ben, get out of here before you wreck my store again," Mr. Baumann said, knowing that something of his gets destroyed every time he came in contact with his next door neighbor.

"Don't worry, Baumann, he won't be staying for long," Psyphon said as he aimed a rather large black and red gun at Ben.

"Nice new toy, are you going to destroy me with it," Ben said jokingly.

"On the contrary, this is as special Quartz Cannon. You want to see what it does?" Psyphon said as he fired at Ben.

Ben tried to reach for the Omnitrix and transform, but the beam from the hit him before he had the chance. While the beam did not hurt, something didn't feel right to Ben as he was surrounded by a red light. When the light dimmed, there was no trace of Ben anywhere. It was as if he had disappeared into thin air.

Psyphon cheered at his success, but his celebration was cut short when a line grabbed the Quartz Cannon out of his hand and returned it to the launcher, Rook, who had arrived with several other Plumbers, including Ben's grandfather, Magister Max Tennyson. The Plumbers quickly arrested all of the gang members in the store and forced them into transport shuttles to process them on the Plumber Base. Rook and Max took the opportunity to demand for Psyphon to reveal what he had done to Ben. Psyphon simply laughed as he said, "I sent him to a place where you will never find him. At least not in this universe."
