History[]
Past[]
Jörmungandr is a dragon that Hiccup Horrendous Haddock III defeated prior to the series. Toothless presumably made sure that none had ever released the serpent as it was the apex predator of the dragons. It was locked in a specialized cage created in the Dark Realm that can only be opened by the muzzle of a Night Fury dragon or a descendant Night light. It is known as the apex predator to all dragons.
