Toothless also got his name because when Hiccup first found him, he had no teeth. He grew one tooth, only to lose it shortly later. The producers decided, with the approval of author Cressida Cowell, that it would be more cinematic to make Toothless large enough to be ridden as a flying mount.

Once thought of as the "unholy offspring of lightning and death itself", Toothless (20 in dragon years) has proven to be much more of a giant, winged pussycat than the stuff of nightmares. Playful, inquisitive, and intelligent, Toothless is more Hiccup's best friend than his pet.
Toothless and Hiccup, the two main characters within the film trilogy, also sustain disabilities.
