Transformers cause very intense violence throughout. Although clearly a fantasy, both Autobots and Decepticons are shown using violence as a means to resolve conflict, including executions, robot dismemberment, knuckle dusters, missiles, and cannons. Although the film outlines Autobots as the heroes and Decepticons as the villains, it does not make a clear moral distinction between their methods, and presents violence as exciting and heroic.
Lots of scenes with massive destruction
Many people are injured during Transformer attacks. Many people are also killed, and it is shown graphically. Alien guns shoot people and they are shown exploding into a mess of clothing and bones, however it is not bloody. These scenes, while intense, are only shown directly and noticeably once.
Buildings, structures, vehicles etc are destroyed and blown up many times.
