Toothless is one of the main dragons in How to Train Your Dragon, and he's known as a Night Fury, which is the rarest and most mysterious dragon species in that world. Physically, Toothless looks sleek and powerful but also surprisingly cute: He has jet-black scales that make him almost invisible at night, giving him his "Night Fury" name. His body is smooth and aerodynamic, kind of like a mix between a panther and a stealth fighter jet. He has large, expressive green eyes, which make his emotions really easy to read-even without words. His wings are wide and bat-like, allowing him to fly incredibly fast ' perform sharp turns in the air.
