First appearing in the 1955 film 'Godzilla Raids Again,' Anguirus is depicted as a spiky, quadrupedal dinosaur-like creature. He is one of Godzilla's earliest foes but later becomes a loyal ally. Known for his fierce fighting spirit and resilience, Anguirus often supports Godzilla in battles against more powerful adversaries, making him a fan-favorite among kaiju enthusiasts.
