Zudomon

Zudomon is a Sea Animal Digimon whose name is derived from the onomatopoeia for a hammer thud (ずどん), and whose design is derived from the walrus. It is a Power Digimon which is a further evolution of Ikkakumon that became able to walk on two legs. It further guards its thoroughly tempered muscles with protectors, which it made from the pelt and shell that it stole from its opponents. The horn on its head has been replaced with one that became impossible to regrow, so it voluntarily processed it into a saw shape. However, after all is said and done its strongest weapon, which it dug up from ancient ice, is its "Thor's Hammer" made of Chrondigizoit.
