Monimon

Monimon (モニモン)
A low-ranking ninja Digimon that always operates in a group. Even though they are said to be in a group, they each operate within a fixed range from the others while hidden under vegetation or in the shade of a rock, and it can be said that while it has the appearance of an underling, it seems to be a ninja after all. Its emotions tend to project on its face, so while it always pretends to be calm, its emotions show up on its face (monitor) in the shape of emoticons. Furthermore, because it even projects its dreams from its face when it is asleep, everyone can see them, and it gets very embarrassed. Its Special Moves are leaping upon the opponent in a group (Rappa), firing a water pistol from its mouth (Suppa), and instantly running away at high speed (Toppa).

Etymology
