We all know Hiccup's story. From how he met his best bud, Toothless, to how he defeated evil masterminds such as Drago Bludvist and Grimmel. But the side of the story we've never looked in to is Toothless's. What was his life like before Hiccup? How did he come under the Red Death's rule? Everything will be answered here. I think is obvious, but I don't own the HTTYD movies or books (unfortunately).
