Anguirus

"Anguirus is a loyal Earth Defender. Although he is neither the largest, strongest, or fastest of Earth's vanguard, he possesses a tenacity of spirit that makes him a fearsome opponent for any monster. Anguirus can stun nearby opponents with his fearsome Sonic Roar, or use his powerful jaws to leave an impression. Anguirus' most unique attribute is his ultra-hard spiked carapace, which can parry any physical attack and inflict heavy edged damage in response. Anguirus can tuck his head and limbs beneath his shell and roll forward-this offers him excellent resistance to attack and allows him to plow through terrain and opponents alike. When the earth is threatened, Godzilla will come to its defense-and Anguirus will be right beside him, until the end."
