Firescales

If a dragonet hatches with too much fire, they will have "firescales," which makes their scales constantly burn and makes the dragon melt and ignite anything that they touch. These firescales dragonets are usually killed by being thrown off the peak of a mountain as either a dragonet or an egg aside from Peril, currently the only known alive firescales dragon.Conversely, some SkyWing dragonets can be born with too little fire. In the case of Peril and Sky, also known as 'Ember,' who shared an egg, Sky had all his fire transferred into Peril.SkyWings also had animus dragons, but since they killed animus dragons as soon as they are discovered (much like firescales dragonets), there are currently no known modern SkyWing animus dragons. Some think that they had killed the animus blood out of the SkyWings.
