Monster (Egg Group)/Characteristics

Monster group Pokémon are usually among the most powerful, and most well-known. Though not as large as the group, the Monster group is still a fairly large group. In terms of general body shape, most appear to be bipedal, although quadrupedal forms are common as well. Many also possess a large tail which may aid in balance and some possess claws on their limbs. Most of them are also partially reptilian, superficially resembling. Mammalian forms are also present.

It is also worth noting that a large number of families in this Egg Group evolve twice over the course of their development. Many Pokémon are capable of breeding with other Egg Groups, but the number of Egg Groups is fairly limited, with only four others.
