Ben 10 vs. the Negative 10: Part 1 is the fiftieth episode of Ben 10.


The Tennysons pick up the grandson of another Plumber named Cooper, who's hitching a ride home with them from summer camp. Meanwhile, a Plumber base at Fort Knox is robbed by the Circus Freaks and Sublimino. By the time the Tennysons find out, they're too late to help, and they discover that the Quadrio ignored the gold in the vault and tore into an underground base, which Max explains is a Plumbers base.

Max explains that there is a Plumber base built into every major military base in the USA. They soon learn of a second robbery at the Seattle Space Needle, another secret Plumber Base. Sadly, they can't get there in time. However, Cooper reveals that by using his extremely proficient technological abilities, he super charged the Rust Bucket's engines, which will allow them to make it in time.

Midway to the base, Cooper realizes that he didn't make super charged brakes to go with the engine and now they're going to run into Seattle at 500 MPH. At this point, Ben as Diamondhead climbs onto the outside of the Rustbucket, creates an anchor and attaches it to the Rust Bucket, forcefully slowing it down.

At this point, the Tennysons discover that this robbery is run by Rojo (having gained a new cybernetic suit), Dr. Animo (who's using a giant mutant bat), Clancy (mutated into a humanoid insect which resembles Stinkfly) and Charmcaster. Grandpa Max discovers that they're searching for the keys to the "Sub Energy", an extremely potent, but unstable, sub-atomic power source (equivalent to the power of 10 suns being concentrated into the size of a golf ball) given to the Plumbers by an alien race in gratitude for apprehending one of their criminals. They lose the second key to the villains, and attempt to intercept them en route to the Mount Rushmore base, where the sub energy is stored. However, they find that the Forever King, joined by a subordinate (a bionic limbed Forever Ninja) and the villains that raided the earlier bases, has beaten them to the base but has yet to gain access. The Forever King dubs his team the Negative 10 and sets them upon the Tennysons.
