The Headcanons Public Library

Now I already posted a thread like this on the School of Dragons forum and got some interesting responses, but now I want your contributions, fellow Grapeviners! If you have HTTYD headcanons you want to share, please do so! The original idea was just to gather headcanons about how dragons might work, but HCs about any part of the franchise are welcome.

I'm not going to copy my entire rules list here, but it basically boils down to "Be polite, respect your fellow fans, and give credit unless the person whose headcanon you want to use has said you can use it without."

Let's compile an awesome library, everyone! :D

Headcanon: Monstrous Nightmare territorial disputes
(Wild) Monstrous Nightmares settle territorial disputes as follows: The one which does not own the territory in question uses his fire to mark a ring around it, then, as loudly as possible, roars a challenge against the one who claims it. More often than not, this 'ceremony' of sorts takes place at night. Should he receive no response (a very rare occurrence), the territory defaults to him. However, in the vastly more likely event that the original claimant accepts the challenge (signified by a challenging roar of his own), it is single combat, either to the death, or until one submits and leaves. It is not uncommon for this contest of prowess to last multiple days.

Headcanon: Dragons' eyes
Don't ask for logical backing arguments for this, because I have none. :P All dragons' eyes actually emit a small amount of light. Especially noticeable in the Monstrous Nightmare, when the dragon is about to breathe fire / use whatever its breath weapon is, its eyes briefly glow brighter; and when it's tired, they glow less brightly (and at least in the Monstrous Nightmare's case, go from a bright yellow glow at full wakefulness through orange and then decidedly a dull red as the dragon is about to drift off into sleep).

Headcanon: Bewilderbeasts' ice breath
I know the official word on the Bewilderbeast's ice breath is "stored seawater", but I came up with an alternate explanation that's a lot cooler (pun not intended XD), and perhaps makes sense. Rather than using seawater, a Bewilderbeast's body synthesizes a chemical from its food that reacts extremely endothermically with air. (Perhaps nitrogen specifically?) This chemical is stored (much like other dragons' fuel) in some sort of air-tight bladder back of the throat. When the Bewilderbeast uses its "ice breath", this bladder is pressurized and the chemical is ejected at high velocity. Once exposed to the air, the endothermic reaction takes place, and the very humidity in the air, as well as possibly water produced by the reaction, is cooled far below freezing, resulting in ice.

This has some interesting implications. For instance, it means that if a Bewilderbeast is not eating well, it will be unable to produce much of a blast. It also means that if one were in a desert or somewhere like that, with zero humidity, the reaction would be unable to take place. Further, as it relies on a reaction with air, the ice blast cannot be used underwater. Also, if something happens and the orifice cannot close quickly enough, there is a chance that the reaction happens in the mouth, freezing tissue and ultimately suffocating the Bewilderbeast when the ice blocks its airway.
