"transformers Megatron" in Transformers Movie Wallpapers.
Description: In the 2007 live Action Transformers film, Megatron appears as a Cybertronian jet. The apparent explanation for the departure from his gun form is that director Michael Bay does not want to include any sort of size changing in the transformations, which the writers described as "cheating". (This significant change in size is known in Transformers fan communities as "mass shifting".) In one of the special features on the DVD, G1 Megatron's transformation was likened to Darth Vader turning into his own lightsaber to be wielded by someone else.
