Anguirus

is a giant monster, or kaiju, which first appeared in the 1955 film Godzilla Raids Again, the second film in the Godzilla franchise produced and distributed by Toho. Anguirus is the first monster to be shown engaging in combat with Godzilla in a film. Since then, the character has appeared conversely as an enemy and an ally of Godzilla in numerous films produced by Toho, including Destroy All Monsters (1968), Godzilla vs. Gigan (1972), Godzilla vs. Megalon (1973), Godzilla vs. Mechagodzilla (1974), and Godzilla: Final Wars (2004). He has also appeared in other media, including comic books, video games and television series.

==Overview== ===Appearance=== Anguirus is a quadrupedal giant or irradiated dinosaur that mostly resembles an ankylosaurus. His head resembles a cross between that of a ceratosaurus and a styracosaurus. He has several horns on the top of his head and a single horn above his nose. His face is long and drawn out, has rows of long, serrated teeth and has two tusks on his upper jaw. His carapace is studded with long, sharp spikes. Anguirus' tail is covered with spikes (he also had a tail club in Godzilla: Final Wars). His tail makes up most of his body length. His hind limbs are longer than his forelimbs, and he can stand up on them to his full height, though he generally walks upon all fours. Anguirus has not one but five brains, one in his head which controls all of his organs, and one above each one of his limbs; each brain most likely controls the limb it is above. This gives Anguirus an advantage in battle, for he can react much quicker than most kaiju. Anguirus first appears in the Showa continuity as brown with yellowish spines, these colors are later changed in the Millennium series to light gray, with orange spikes and horns.
