Jamie Liddell (Storm Toy Photography) on Instagram: ""Nobody summons Megatron" The Transformers: The Movie origin of Galvatron. Another iconic scene. Animation, pacing, and voice acting all superb. A transformation scene that has inspired toys and collectibles, as Megatron becomes Galvatron. Orson Welles as the voice of the chaos bringer Unicron. Megatron makes a deal with Unicron (the devil) for a new body and new troops to command. I bet we all knew the words in this scene. See if you can use
