Anguirus is stated to be a "voracious, carnivorous dinosaur" despite the real-life Ankylosaurus species being herbivorous. He is stated to be incredibly aggressive, especially toward other aggressive creatures. Despite his tenacity, he attempted to flee once Godzilla gained the upper hand. An in-universe textbook by Polish professor Preterry Hawdon claims that Anguirus has a thorough hatred for "war-like predators".

Originating from the Siberian tundra, Anguirus is an Ankylosaurus that lived during the Cretaceous, 150 to 70 million years ago, around the same time as Godzilla. Like the original and Showa Godzillas, Anguirus managed to survive into the modern day by lying dormant before being awakened and irradiated by hydrogen bomb tests in the 1950s.

When pilot Shoichi Tsukioka landed on Iwato Island to rescue his friend and colleague Koji Kobayashi, the two men discovered Anguirus and a second Godzilla locked in battle on the island. The two monsters eventually tackled each other into the ocean, and disappeared. The pilots reported their story to the authorities in Osaka, who determined that Anguirus was a creature that lived alongside Godzilla in prehistoric times, and like Godzilla had been reawakened by nuclear testing. The J.S.D.F. enforced a blackout on the city and used flares to draw Godzilla away, but when a group of prisoners escaped from a prison bus as it was evacuating, they led the police on a high-speed chase that ended with a gasoline truck crashing into a refinery and starting a huge fire. This fire quickly spread and drew both Godzilla and Anguirus into Osaka, where they resumed their battle. The monsters tore apart the city as their battle reached Osaka Castle. Godzilla tackled Anguirus into the building, then bit down on his opponent's neck. Anguirus roared out in agony as he began to bleed profusely, and was thrown into a moat by Godzilla. As Anguirus attempted to stagger back to his feet, Godzilla unleashed his atomic breath, incinerating his foe and leaving him victorious.

Anguirus is a stout, armored, quadrupedal reptilian creature that looks fairly similar to an Ankylosaurus, with aspects of his design also resembling armadillos, hedgehogs, and crocodiles. He has seven inwardly curved horns at the top of his head and a single, short horn on the end of his snout. His face is long, puffy and drawn out, like a crocodile, with two large tusks at the start and rows of smaller, jagged, serrated teeth following suit. His carapace is studded with a plethora of long, sharp, prickly spikes. Anguirus' tail is spiky and longer than his body, accounting for the majority of his total body length. His hind limbs are longer than his forelimbs, enabling him to stand upright to his full height, but he primarily walks upon all fours.
