Trivia

 * As a reference to its title, Ben 10: Aliens Unleashed has the most aliens seen in a single season. These aliens are also the strongest they've ever been, Ben having "unleashed" their true power and potential.
 * It is confirmed that never-before-seen aliens will appear at the end of the Aliens Unleashed series. They will be Ben's main set of ten aliens in the next series.
