Transformers: Prime (Seasons 1–3)

Transformers: Prime (2010–2013) is the CGI animated series you can watch online on iFILM. Optimus Prime leaves a small Autobot team behind on Earth once the war seems over — a good call, because three years later Megatron resurfaces wielding the deadly Dark Energon.

The robots run a hidden base out in the Nevada desert, and three local kids — Jack, Miko and Raf — stumble straight into the secret. From there it's humans and Autobots watching each other's backs while the Decepticons hunt across the planet for ancient power. Peter Cullen voices Optimus, the same voice fans grew up with, with Frank Welker as Megatron and a villain bench that includes Jeffrey Combs and Tony Todd. Three seasons plus the wrap-up film Predacons Rising, the show is complete, so you can stream every episode in order.

Built by Hasbro with Japan's Polygon Pictures, this is that rare kids' robot show willing to kill off characters and treat loss seriously. It works for anyone raised on the 1980s Transformers and for newcomers alike. Stream Transformers: Prime online on iFILM.
