Chief of the Autobots, Prime battles the power-mad Decepticons. In Bay’s movie, he doubles as a long-nose truck cab — a controversial upgrade from the flat-front cab in the cartoons.
In the movie, the über-nasty head Decepticon transforms into a massive, unearthly jet. On TV, he became a small pistol others had to hold, a physics-cheat that the film avoids.
An Autobot spy (and fan favorite), he’s sent to Earth in the film to guard the teenage boy who unwittingly holds the key to conquering the universe. And now, he’s into classic-pop radio.
