Nature Spirits

Nature Spirits is a Field in the Mon series. This field mostly revolves Mon who are "generic" and live in the woods, cities, and "Normal" grasslands. Mon in this field are normally Bug, Fire, Grass, Fighting, Normal, Fairy, Rock and Ground types, however, other Mon of other types can appear here as well. Nature Spirits is normally seen as the "default" or normal Mon Field, so many Mons of this type are popular, or easy to use, often being found early on.

Generation I
In Generation I, a Nature Spirit egg was one of the first eggs the player could find in the early Monz games. This egg started with Botamon, or Bubbmon and the evolutions tranversed from there. It's noted due to many of the more popular Mon species being from this Egg.
