Every version of Ben 10 — the films & series, compared across media.
Ben 10 follows ten-year-old Ben Tennyson, who finds a mysterious device that lets him transform into ten different alien heroes — each with distinct powers — and discovers the responsibility that comes with them. The franchise returns repeatedly to the same core cast: Ben, his cousin Gwen, and Grandpa Max on a summer-vacation road trip. That setup has anchored multiple animated series and a live-action film.
No — Ben 10 originated as an animated television series in 2005. All versions covered here, including the 2016 animated series and the 2008 live-action film, stem from that original series.
This page covers three: the original 2005 animated Ben 10 series, the 2016 animated series also titled Ben 10, and the 2008 live-action TV movie Ben 10: Race Against Time.
The 2005 animated Ben 10 is the original. The 2016 series returns to the same setup independently under the same name, so either animated series is a reasonable entry point.
