Fearsome Fairies

Maybe design-wise too complicated for pokemon, but still fun.

Dramite, the sprite pokemon
Dramite is a small dragon and fairy-type pokemon that lives in old woodlands and glens. Although its appearance seems very friendly, it is an active hunter. Princesses in ancient times often kept dramites for pets in the royal court both for their adorable looks, and for protection. Dramite evolves into maurrush at level 40.

Maurrush, the wyrm pokemon
Maurrush is a medium-sized dragon and fairy-type pokemon that lives in deep, old forests, and is rarely sighted in the wild. Like its previous form, maurrush is an accomplished hunter and won't hesitate to use its powerful mystical abilities on prey. It is friendlier to humans and will try to beguile them with illusions before fleeing. Maurrush evolves into titaniamat at level 55.

Titaniamat, the wyrm pokemon
Titaniamat is a large dragon and fairy-type pokemon that lives only in unspoiled wilderness, and is so rare that it was believed to have been a myth. Its image is common in heraldry from around 1000 years ago, and represented both compassion and strength. Titaniamat sometimes help humans who have lost their way, but use their powers to erase the person's memory of their appearance afterwards.
