Studies have shown that this Pokémon's evolution has come about by it ingesting and adapting to various forms of toxins, pathogens, and poisons over the years. Because of this, its own bodily composition and fluids remain hazardous to any being that does not share its own body chemistry; its own saliva is capable of dissolving wood and kill a full grown tree in a half a minute. Despite this, Virutileon's evolutionary processes made it capable of manipulating its own body chemistry to ingest even the most toxic of plants and foods, to producing poisons used in its attacks, and producing antibodies and vaccines more powerful than any known manmade cures; in the wild, it is known to feed these vaccines to those who have garnered its trust and companionship.
