خلاصه داستان : داستان بن تنیسون، یک بچه معمولی است که پس از کشف Omnitrix، یک وسیله اسرارآمیز بیگانه با قدرت تبدیل پوشنده به ده گونه مختلف بیگانه، بسیار غیر معمول می شود.

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.
