SkunkyArt | Nyxeii — Rubillacsir (Ruby) [referece]

Ruby is a fairy, so it is genderless, their anthro form looks a bit more femenine so people think they're a girl (it's fine for them, they don't care about it)

all their body inside is made of ruby and illacsir (a magic crystal that exist in my altern reality that is even harder than diamond)

Their complete name is "Rubillacsir" (named by Nyx because of their components, ruby + illacsir) but they decided to rename themself as Ruby (or however you say "Ruby" on your lenguage, since i speak spanish i call them Rubí) for make it more simple.

wings in fairy/feral form AREN'T OPTIONAL.

They never walk in their original (fairy) form, they are always flying/floating.

Their wings in anthro form are optional, but in canon they desapear (or merge with the rest of their body) when they change their form.

They control the fire on their wings, it doesn't burns unless ruby wants to.

their weapon (for anthro only) is a spear, made by ruby, illacsir and their magic (... example later)

they're the diciple/friend/assistant/girlfriend (kinda?) of Nyx .

fire elemental and mystic mage.

They AREN'T inspire on steven universe, their original dessing was created before SU (and it was actually created by an old friend of mine), the redesing and the actual "concept" was actually INSPIRED in houseki no kuni (manga)

They aren't a cat, they're a red panda.
