The latest film in the "Transformers" franchise - "Transformers One" - is finally in theaters, and this time it's animated. The new film from director Josh Cooley serves as a prequel to the entire universe and chronicles the early days of Optimus and Megatron's friendship.

That’s where the characters find themselves in “Transformers One,” the animated origin story of Optimus Prime and Megatron. Up to this point in the movie, the film’s leads have not been in the possession of the cogs needed to transform.

Transformers One features the Elder Primes as key elements of the narrative, tweaking the lore surrounding the earliest heroes of Cybertron.
