Infermon is an Unidentified Digimon. It has an appearance like a long-legged spider, and while its form is usually in an outstretched state, with its head and limbs extended, it is also able to assume a cocoon form, with its limbs retracted into its body. When it goes into its cocoon form, its defensive power is raised such that every attack is deflected, but it can only go forward in a straight line, and the fact that it cannot modify its trajectory is a clear weakness. It is able to penetrate every Network, despite the strength of their security. If Infermon is released from the Network, the world will probably then collapse into chaos.
