Toothless

Toothless is an extremely rare, male Night Fury befriended by Hiccup, and the dragon that lost his left tail fin in the first feature film. He has dark black scales, retractable teeth, and the ability to shoot plasma blasts. He also has the unique ability to navigate in dark places using echolocation. As Hiccup's dragon, Toothless shares the strongest bond of all riders and dragons, a partnership that defines the series.
