Envy develops strong, rigid claws out of it's constant longing for more. It's a deadly predator that seeks to obtain everything it sees, and attempts to keep others under control with an iron fist. It is slowed by quite a bit of heavy baggage due to the thick metallic coat that covers it's body, but is capable of attacking with devastating force. Your Envy will demand all of your attention, but will also love you dearly for it. 
Can talk, dispite being a metallic dragon.  Yandere.
