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.[4]

Octomon resembles a red octopus whose head is covered by a brown, broken pot, which is also adorned with a gold crown and pierced through with three black-striped horns. Its mouth, which is in the bottom of its mouth, has seven teeth. Island Zone in Chaos! Its face cannot be seen, as the opening that reveals its eyes is covered in shadows. Attached to the pot are also yellow, glowing eyes that may be Fujitsumon. The tips of its tentacles have black claws from Devidramon. It wields a cutlass in one of its right tentacles and a gun in one of its left. The character on its gun reads "Ink" ( Sumi?).
