Vouirvre:
Guivres are also well known as vouivres, and the terms have become synonymous. For example, in The Drac: French Tales of Dragons and Demons, the vouivre is depicted as
a female creature with dazzling, green scales which emanate sound as the vouivre flies. The vouivre is depicted as greedy, her head crowned with pearls and a golden ring about her tail. The beast in this story stayed in a cave for most of her time, then left to bathe only for a few minutes.
Flygon:
Flygon resembles a slightly insectoid, bipedal dragon.
It is primarily light green and has a pair of large rhombus-shaped wings with a red trim, toeless hind legs, and skinny arms with three-clawed hands.
Its tail has several dark green stripes and three small green rhombus shapes with red trims at the end. It has large eyes, and a pair of green antennae that point back. The eyes have red covers that prevent sand from getting into its eyes. With its wings, it kicks up sandstorms to hide itself.
Its wings make a "singing" sound when they are flapped, earning Flygon the name "The Desert Spirit". It lives in the desert.
Mine hatched female, looks like I found her name.
