Two years after this, Optimus takes this tactic to the utmost extreme, using his blades to tear off Grindor's in a battle in a forest, while later using a blade to slice off the Fallen's face in Egypt Revenge of the Fallen
Animated continuity
The Headmaster uses his Headmaster unit to cut off the heads of Transformers so that he can take control over their bodies. Yet this does not kill his victims.
Two stand out examples of surviving decapitation are worth noting. The first is the example of Megatron, who was decapitated during an uncontrolled re-entry into Earth's atmosphere. Transform and Roll Out He was sent into stasis lock as a result, but was reactivated fifty years latter thanks to Sari Sumdac's key, which had been powered with the energies of the AllSpark. Home Is Where the Spark Is
The other major example is Starscream, but this is atypical. Starscream's survival was because of an AllSpark fragment embedded in his head, meaning he could survive any normally spark threatening injury as long as the shard was in his head. Mission Accomplished
