WATERTOWN, New York (WWNY) - ‘Autobots, Roll Out!’ is just one of the well known catchphrases you’ll hear in and around the Cerow Recreation Arena in Clayton on August 20,21,22 this year. Why? Because parked outside will be the world’s only Hasbro approved, fan built, Optimus Prime truck. He lights up, he talks to you, and you can come meet him. Get your photo taken with Optimus Prime or any one of more than a dozen celebrities, artists, and performers spanning fandoms from television, movies, gaming, streaming, comic books, and anime!
