Ikkakumon is a Sea Animal Digimon whose name is derived from the narwhal (Monodon monoceros) (一角獣 Ikkakujū?) and whose design is derived from the narwhal, the walrus (Odobenus rosmarus), and the polar bear (Ursus maritimus). It was discovered by the computer of an Arctic exploration base. Its thick fur and stout body are structured so that it can endure even freezing lands. Its sharp horn is made of "Mithril", one of the rare metals, and the skin under its fur is just as hard. The portions of its soles where its claws attach are heat tops that are able to give off high temperatures at will. As such, it's able to maintain a tight footing when on ice, but it isn't able to move very nimbly. When in battle, it will intimidate the opponent with an impressive roar similar to a lion's.
