Showa Anguirus

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 several 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's 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

Anguirus is depicted as a very tenacious and fierce fighter. Despite constantly going up against enemies tougher than himself, Anguirus rarely backs down and always puts up a vicious fight. Despite his fierce nature, Anguirus has traditionally been shown in various media as being a close friend of Godzilla. While many of Godzilla's allies have had to work with him out of necessity, such as Rodan and Mothra, Anguirus, Godzilla and Anguirus appear to have a genuine friendship
