Zudomon

Zudomon is a Sea Animal Digimon. His name originates from the Japanese word zudon, the sound of a thud. He resembles a giant gray and orange walrus wearing a turtle shell with large spikes coming out of it. An Ikkakumon that evolved into a powerful Digimon where walking on two feet becomes possible. Furthermore, it guards itself with a skin and shell armor it has made from opponents. It unearthed a powerful Digimon from the ancient ice made of Chrome Digizoid. He wields a giant hammer called "Thor's Hammer". Because it is made of Chrome Digizoid, it is believed to be indestructible.
