Anguirus tunneled his way to a snowy region, where he witnessed Mechagodzilla's first emergence in "Godzilla vs. Mechagodzilla". He followed Mechagodzilla underground to Japan where he revealed himself to call upon the real Godzilla and engage Mechagodzilla in battle. However, Mechagodzilla was too powerful for Anguirus and severely injured him, breaking his jaw in a bloody display. Anguirus was forced to retreat underground, although he managed to tip off humanity that his opponent was not the true Godzilla. Showa Anguirus was 60 meters (197 feet) tall, 100 meters (328 feet) long and weighed 30,000 metric tons.
