Anguirus

The Anguirus (アンギラス Angirasu?) of the Showa era is a mutated Ankylosaurus kaiju created by Toho that first appeared in the 1955 Godzilla film, Godzilla Raids Again.

Name
The original English name given to Anguirus by Toho was "Angilas", given the pronunciation of the name in Japan, which was changed to Anguirus in the 1959 American release of Godzilla Raids Again, with the film's title being changed to Gigantis, the Fire Monster. In the mid-1990s, Toho copyrighted the revised name "Anguirus," making it official.

Design
Anguirus is a four-legged dinosaur-like creature that combines the features of an Ankylosaurus, a Styracosaurus, and a crocodile. He has several horns at the top of his head and a single rhino-like horn above his nose.

His face is elongated with a long snout bearing rows of jagged, serrated teeth and his carapace is studded with long, sharp spikes. Anguirus' tail is longer than his body and makes up most of his body length, and is also covered with spikes. His hind limbs are longer than his forelimbs, enabling him to stand up on them to his full height, but he generally acts as a quadruped.
