Mokumon

Mokumon is a Smoke Digimon whose name and design are derived from "Smoke Cloud" (『もくもく』). It is a Digimon Baby which surrounds its body with a vaporous smoke. Unlike other Digimon, it is unique in that its DigiCore is bare, and in order to protect it, it conceals the DigiCore within a lot of smoke. Because its DigiCore is bare, its body is shrouded in smoke while it burns and it is a Digimon with an unusual way of life. The smoke sometimes burns the DigiCore due to an outbreak, but this doesn't seem to harm Mokumon or others. Also, because it is still digivolving, when it encounters an opponent it immediately flees. If you happen to see one, it would be best to be quiet.
