Volcdramon

Volcdoramon is a Dragon Digimon and carrier of the X-Antibody whose name and design is derived from "Volcano Dramon." It is a Volcano Dragon Digimon that inhabits the magma beds of the active volcanoes that dot the Digital World. It is said that volcanic eruptions occur due to the activity of Volcdoramon, so the Digital World's volcanologists study not volcanic activity, but the activity of Volcdoramon and the stirring of volcanoes. Although its appearance is that of a terrifying figure, its personality is gentle, and it is not the type to like conflict. However, if it's offended just once, you will surely suffer its scorching attacks like a "raging fire".
