Throughout the film's running time, Godzilla's multiple forms are never given specific names, and are just referred to by numbered titles, such as the 'fourth form'. However there are some names (the names are never revealed in the film) like Godzilla's second form is named 'Kamata-kun', his third form named 'Shinagawa-kun' and his fourth form named 'Kamakura-san'. However, there are no names for his first and fifth forms.
