Godzilla from 1955. He is 50 meters tall. In the American dubbing of "Godzilla Raids Again", the movie with 1955 Godzilla, his roar was edited to sound like Anguirus's roar. He is slimmer than 1954 Godzilla so he would be more flexible for his battle with Anguirus.
Very similar to 1954 Godzilla, 1955 Godzilla was slimmer in build and had a smaller head. He had only three toes, while 1954 Godzilla had four. He still has the same plates, though.
