Ben 10 (Seasons 1–4)

Ben 10 (2005) is the classic Cartoon Network animated series you can watch online on iFILM. Ten-year-old Ben Tennyson stumbles across a strange alien device in the woods — and before he can drop it, the Omnitrix locks around his wrist. He can now transform into ten different alien heroes, each built for a different kind of fight.

Ben hits the road with his cousin Gwen (Tara Strong) and grandfather Max in an old RV. Summer trip, sure — except every other day brings a bounty hunter, a rampaging villain, or the wrong alien transformation at exactly the wrong moment. Each episode is its own adventure, and Ben has to figure out which of his ten forms will get him out of this one.

The show launched an entire franchise: multiple sequel series, TV movies, and a generation of fans who still know every alien by name. Stream Ben 10 online on iFILM.
