Monster-type

Just as a sizable chunk of Normal-types were retconned to Fairy due to their "cute" designs and not being based on animals/living things (barring Granbull), a Monster type would handle a portion of Pokemon who are "grotesque" in design and yet not based on specific animals/living things. Its type chart is designed to communicate Monster-types as being more "powerful" Normal-type Pokemon.
