Metal Godzilla's name comes from metal (メタル, metaru?) and Godzilla (ゴジラ, Gojira?).
Like the other original Godzilla Generations monsters, Metal Godzilla's design is very simple. It is a chibi creature with a complex green texture, small dorsal plates, a tail, and a pair of yellow eyes with red pupils. It shares its basic 3D model with Godzilla.
