  • Notes

    • Of the 17 aliens on the Omnitrix at the time, thirteen of them were featured in the show (either as one of Ben's changes or as natural aliens).

      Of those thirteen, Ben changed into eleven.

      The four that did not appear are the four DNA-absorbed aliens at this point in the series, Ghostfreak, Benwolf, Benmummy, and Benvicktor.
