Transformers: Devastator is a 2025 American science fiction action film directed and co-written by Neill Blomkamp and produced by Zack Snyder and Jerry Bruckheimer. Based on Hasbro's Transformers toy line, it is the second installment in the Cybertron Quadrilogy and the sequel to Transformers Begins. The film stars an ensemble cast including Peter Cullen, Jeffrey Combs, Justin Chatwin, Sasha Calle, Kevin Nash, John Cena, Mads Mikkelsen, Katherine Waterston, Daniel Kaluuya, Idris Elba, Sam Elliott, and Josh Brolin as Megatron. In the film, Optimus Prime must lead the Autobots against a powerful, giant member of the evil Decepticons known as Devastator, while also coming back into conflict with the cruel Megatron. Transformers: Devastator opened in theaters on October 17th, 2025; grossing over $715 million worldwide against a budget of $150 million, the film was a financial success, though it received mixed reviews, with praise for its visual effects, action sequences, cinematography, performances (particularly Cullen, Calle, Mikkelsen, and Brolin), and musical score but with criticism to the plot, pacing, tone and length. A sequel, Transformers: Space Bridge, was released one year later.
