Anguirus resembles a cross between an ankylosaurus, a porcupine, and an armadillo. He generally crawls on all fours but can stand upright as well. Anguirus has light gray skin, a spiny carapace, a spiky tail that sometimes ends in a club, a crown of spikes on his head, a small spike on his nose, and large human-like eyes. In the Showa era, Anguirus is 60 meters tall when standing on his hind legs, 100 meters long, and weighs 30,000 tons. In Godzilla: Final Wars, Anguirus is 90 meters tall when standing on both legs, 160 meters long, and weighs 60,000 tons.
Anguirus is a type of ankylosaur called an anguirosaurus. Anguirus lived during the same time period as Godzilla and their species were natural enemies. Anguirus survived to the present day much like Godzilla and Rodan and was awakened by nuclear testing.
Godzilla Raids AgainEdit
Two pilots witnessed Godzilla and Anguirus doing battle on the remote Iwata Island. Both monsters fell into the ocean together and vanished. The Japanese Self-Defense Forces mobilized against the monsters and even used flares to lure Godzilla away from Osaka. Anguirus was not so deterred and crawled onto land in Osaka. A freak refinery fire caused by a failed prison escape lured Godzilla to the city as well, prompting the monsters to resume their battle. Godzilla and Anguirus fought viciously across Osaka, demolishing the once-proud metropolis. Their battle reached the Osaka Castle, which was destroyed as Godzilla tackled Anguirus into it. Godzilla then sunk his teeth into Anguirus' throat and tossed his weakened opponent into a river. Godzilla blasted Anguirus with his atomic breath and left the monster for dead, returning to the ocean to rest.
Godzilla vs. GiganEdit
Anguirus was subsequently captured by human military forces and was eventually relocated to Monster Island, a facility built to contain Earth's monsters. Anguirus lived on the island alongside other monsters like Rodan, Mothra, and Gorosaurus. Godzilla was now residing on the island as well with his son Minilla. Godzilla and Anguirus gradually overcame their past differences and gained respect for each other. When Godzilla overheard the playing of the Nebulan Aliens' action tapes, he asked Anguirus to investigate for him. Anguirus agreed and escaped the island to head for Japan. Anguirus was met with resistance from the misguided Japanese Self-Defense Forces and returned to alert Godzilla, not wanting to provoke a fight with the humans. Godzilla escaped the island as well and headed to Japan with Anguirus, intent on stopping whatever the Nebulans' plans were. Godzilla and Anguirus were greeted by Godzilla's evil nemesis King Ghidorah and a new cybernetic monster named Gigan. The four monsters engaged in a tag-team battle but Godzilla was overwhelmed by Gigan's brutality. Anguirus attempted to help Godzilla, but was attacked by Ghidorah. After knocking Godzilla out of commission temporarily, Gigan unleashed his fury upon Anguirus as well, slicing his face open with his abdominal buzzsaw. With the help of a band of humans, Godzilla and Anguirus turned the tide of battle and forced Gigan to retreat. After briefly double-teaming King Ghidorah, Godzilla and Anguirus watched as he too retreated to space. Their mission completed, Godzilla and Anguirus returned to Monster Island peacefully, now trusted friends and allies.
Godzilla vs. MegalonEdit
An underground nuclear test ravaged Monster Island the following year, causing Anguirus to fall into a fissure.
Godzilla vs. MechagodzillaEdit
Stuck deep underground, Anguirus tunneled to Japan. He surfaced in the countryside near Mt. Fuji and called out for Godzilla. His call was met by a creature appearing to be Godzilla. Anguirus saw through the creature's disguise and attacked it. The fake Godzilla overpowered Anguirus and even mercilessly broke his jaw. Seriously injured, Anguirus burrowed back underground to heal, hoping Godzilla would hear his call and come to battle the impostor.
Destroy All MonstersEdit
In the year 1999, Anguirus was now relocated to Monsterland, an island in the Ogasawara chain, along with Godzilla, Rodan, Mothra, Gorosaurus, Baragon, Varan, Manda, Kumonga, and Minilla. The Kilaakian aliens attacked the island and placed the monsters under mind control, sending them to attack Earth's cities. Thankfully, the aliens' control was broken by the humans and Godzilla led his fellow monsters to Mt. Fuji to destroy the aliens' base. The monsters were attacked by the evil King Ghidorah, and Anguirus was one of the monsters at the forefront of the battle. Anguirus bit one of Ghidorah's necks and was lifted high into the air when he attempted to fly away. Anguirus' mouth was pried off of Ghidorah's necks and he plummeted to the ground. Ghidorah landed and stomped Anguirus into the ground before turning his attention back to Godzilla. Anguirus shook off the dirt and re-entered the fray. Together with the help of his fellow Earth monsters, Anguirus was able to pin down Ghidorah while his allies stomped him to death. Following the death of King Ghidorah and the destruction of the Kilaakian's base, Anguirus was returned to Monsterland to live in peace.
Godzilla: Final WarsEdit
Anguirus was placed under mind control by the Xiliens and sent to attack Shanghai. Anguirus demolished EDF forces in the area before being beamed up by an Xilien UFO, giving the impression that the Xiliens had stopped him. When the EDF eventually uncovered the Xiliens' plans for world domination, Anguirus was deployed along with Rodan and King Caesar to battle Godzilla. Godzilla defeated all three monsters and left them unconscious and stacked on each other in a pile before continuing towards Tokyo.
- Spiked Carapace - Anguirus possesses a spiked shell on his back. This carapace can protect Anguirus from enemy attacks and inflict damage if Anguirus slams his back into an opponent,
- Body Armor - Anguirus' entire body is covered in armored flesh while his back is covered in a spiked armored shell. Anguirus makes up for his lack of physical power by fighting up close and taking enemy attacks head-on, knowing that he can take the damage.
- Roll Attack - Anguirus can tuck his limbs into his shell and roll into enemies while gaining speed and banking himself off of surfaces.
- Tail Club - In Godzilla: Final Wars, Anguirus possesses a club on his tail that can be used as a weapon.
- Sonic Roar - In the Atari Godzilla video games, Anguirus can project a powerful sonic roar from his mouth that stuns and injures opponents.
- Perseverance - Anguirus always fights until the bitter end, often sustaining gruesome injuries like a torn throat, shredded face, or a broken jaw. Despite being one of the smaller and more underpowered kaiju, Anguirus is unafraid to take on opponents larger and considerably more powerful than himself, including King Ghidorah, Gigan, and even Godzilla.
Anguirus lacks energy-based attacks and must rely on physical tooth-and-nail attacks. Unfortunately Anguirus is small by kaiju standards and his attacks have little effect on monsters like King Ghidorah. Anguirus also has a tendency to bite off more than he can chew, in that he often tried to take on monsters that are bigger and physically superior to him by himself. Unfortunately, Anguirus is rarely successful in these fights and has never won a battle without Godzilla's assistance.
- Anguirus' Japanese name, Angirasu, is short for "angirazaurasu," the Japanese transliteration of "ankylosaurus." Anguirus was often called "Angilas" or "Angweerus" in English dubbed versions of the movies, but Toho maintains that "Anguirus" is the correct spelling of the character's name in English.
- Anguirus was at one point considered to be the star of Toho's original giant monster film in 1954, but was discarded in favor of Godzilla. Toho would instead use Anguirus as Godzilla's first enemy in the sequel Godzilla Raids Again.
- Anguirus was Godzilla's first enemy, but ultimately became his closest and most trusted ally.
- Anguirus was going to be Godzilla's ally in the cancelled 1995 film Godzilla vs. Ghost Godzilla. Even though the film was never made, concept art of Anguirus for the film exists.
- The original draft of Godzilla, Mothra, and King Ghidorah: Giant Monsters All-Out Attack was entitled Godzilla X Varan, Baragon, and Anguirus: Giant Monsters All-Out Attack and featured Anguirus and Varan in place of Mothra and King Ghidorah. Anguirus would have played the same role as Mothra and would have been called "god of the sea." Toho forced director Shusuke Kaneko to replace Anguirus and Varan with Mothra and King Ghidorah in order to increase the film's marquee value.
