Hookfang is Snotlout Jorgenson’s Monstrous Nightmare, a Stoker Class dragon. Hookfang - Monstrous Nightmare / Stoker Class Image via Dreamworks Although Gronckles are slow fliers, they substitute their speed for impressive manoeuvrability. Sometimes, Gronckles even fall asleep while flying. Grockles are one of the toughest dragons out there, but they can be extremely lazy and often spend their time sleeping in communal heaps. Meatlug in particular, though not every Gronckle, has adopted somewhat of a dog-like personality - as shown when she rolls around in the dirt and whines. What Gronckles lack in raw power, they make up for in cunning tactics and strategy. Meatlug’s gentle nature defied every belief held by vikings before the end of the Dragon War, especially in regards to all dragons being monstrous, heartless and homicidal. Unlike most other Gronckles, Meatlug is extremely affectionate toward others - especially her rider - and has a huge appetite, much like Fishlegs. Gronckles are Boulder Class dragons, if it wasn’t immediately evident from their rough, sandy exterior. Meatlug is a Gronckle belonging to Fishlegs Ingerman.

Just like the Night Fury can camouflage during nightfall due to its jet-black scales, the Light Fury can do just the opposite she can blend in with brighter skies even in the daylight due to her shimmering translucent scales. Queen of The Hidden World, the unnamed Light Fury that Toothless encounters in the third film seems to be the female counterpart to a Night Fury - sharing the same characteristics but existing as a ‘sunnier’ version - distinguishable more by gender than abilities.
