Plot
Ben: Rook, I'm bored. Give me something to do.

Ben 18: Yeah! Yeah! Something fun to keep me from becoming Destructodevil and destroying this ship!

Rook: I am sorry, but there is nothing I can do. Intergalactic crime levels have been awfully low recently. It is truly a mystery about what happened to them, Ben-Dude.

(Suddenly, a hologram of Grandpa Max pops up from the dashboard. It glows red, becoming brighter and then dimmer again repeatedly.)

Max: Ben, I have a very important mission for you to do and... hey, who's the green shirt kid and the giant blue cat?

Ben 18: Oh, alternate dimension guys. Meet alternate me and alternate Rook.

Ben: If you want to avoid confusion, I'm called Ben 10 and this is... Rook 10, I guess.

Grandpa Max: Well, uh, I guess you can never have too many Omnitrixes or sidekicks. Anyway, Viscosia is in trouble. To help you understand better I'll play a recording of what's going on.

(Recording starts, showing a massive army of Techadon Robots with red, glowing eyes and rattling lines at the bottom of their heads that look like mouths. Also, the robots are covered in bolts of all sizes.)

Ben: What are those things? They look like Techadons but... different. More like a species.

Robot 1: Mission objective deleted. Cannot recall what objective is. Sending help signal.

Robot 2: Mission objective opened. Suck up Viscosia's atmosphere to power the death cannon.

Robot 1: Sending thank you file. Downloading mission objective. Mission objective downloaded.

Robot 3: Charging Blayckan Vacuum Rifle. Blayckan Vacuum Rifle charged. Preparing attack files.

(In the distance a Polymorph points out the robots to a small group of other Polymorphs and a Sludgepuppy.)

Polymorph: Hey, what are those things and what are they doing here?

Sludgepuppy: Think we should alert Sheriff Mucus?

(Recording ends)
