Octomon is a Mollusk Digimon. It is a fiendish hacker, and was discovered from the virus it used to crash a rival's research computer. It has a nasty habit of collecting things; the tips of its tentacles are affixed with claws obtained from a Devidramon's data, and it is clad throughout with Digi-Treasure which it gathered from the bottom of the Net Ocean. Fujitsumon, a kind of tiny Shellfish-type Digimon, cling to the pot it wears on its head. These Fujitsumon develop their senses, and it is thought that they have formed a symbiotic relationship so that if they sense danger, they inform Octomon.[5]
