Basic things:
GhostFuries are based on different types of ghost. They don't have a specific color. Ghostfuries are known to have peirsing. Like Queen Bell has 3.

Wings and Tails:
Royal wings and tails have purple markings.
Rare wings and tails have a fadding affect.
Regular wings and tails are just plain.

Tails:
Royal and regular tails have flexible spikes, rare tails don't.

Flexible spikes:
Flexible spikes can only hurt other species; there for if two GhostFuries want to battle they have to do a talon to talon or a fire battle. They can also be moved different directions.

Eyes:
GhostFuries' eyes matter a lot. For example, Queen Bell's eyes are like this:

They go from dark to light or sometimes light to dark.
Almost every GhostFury has dark to light eyes.

Abilities:
GhostFuries have fire, of course. But they can also turn into ghost. If a GhostFury has a very happy and nice personality, when they turn into ghost their personality is the opposite of their non-ghost form.

Mating:
GhostFuries can mate with other species but it has to be a secret. Because if the Queen finds out, they would be killed.
When mating male's puff out their chest and make a raptor-sounding sound. Females, on the other hand, they move their spikes and make a whistle sound that is very soft.
