Troopmon

Troopmon is an Undead Digimon. It is an artificial Digimon manufactured by stuffing energy stolen from other Digimon within a special rubber body. As it is a machine-like Digimon that can only perform as commanded, it is absolutely incapable of spontaneous behavior. It doesn't get fatigued, it doesn't feel pain, it doesn't fear death, and it doesn't need to sleep. It is definitely a fighting machine. Its collective behavior is pretty basic, and its individual fighting strength is not very great, but that probably isn't able to make a dent in the extent of its confidence in its ability for, just due to its strength of numbers. An injured Troopmon will just exhale its energy filling, transferring it to a new special rubber body which is reborn as a new Troopmon, so it is actually sent out to the battlefield many times over.

Design
Troopmon is a humanoid Digimon wearing a black rubber suit that obscures most of its features. Its face is covered by a gas mask that has tubes connected to the pack on its back. It has three fingers on each hand with what appears to be ports at the fingertips, and its feet look mechanized, with three clawed toes on each.
