The Sub Energy is an alien energy source that first appeared in Ben 10 vs. the Negative 10: Part 1.
It is said to have the energy to destroy an entire continent. It even makes nuclear power plants look like wind-up toys in comparison. The energy source is kept in a spherical container.
It is said that the Sub Energy is 20 times more powerful than the Sun itself.
Originally, it was given to the Plumbers of Earth sometime in the past as a reward by grateful aliens, for capturing an alien fugitive. Despite the good the Sub Energy could do for mankind, it was deemed too dangerous to be used and locked up at Mt. Rushmore.
In Ben 10 vs. the Negative 10: Part 2, Driscoll managed to steal it and equip it to his Power Suit. With it, he was able to empower himself, but Perk Upchuck managed to rip it off and used it as an attack aimed at the sky, while accidentally destroying the presidents' faces at Mt. Rushmore.
The Sub Energy can also be seen in the Ben 10: Alien Force video game, where it's the power source for a trio of weather machines.
It also appeared in Vilgax Attacks, where it's the power source of Vilgax's Null Void Projector. It's mentioned that the energy source can be made using the left over nuclear waste of Vulpin or the energy present in Taydenite.
