Synopsis

When 10-year-old Ben Tennyson discovers a mysterious device, he gains the power to change into ten different alien heroes, each with uniquely awesome powers. With such abilities at his disposal, Ben realizes a greater responsibility to help others and stop evildoers, but that doesn't mean he's above a little superpowered mischief now and then.
