No, you cannot make a OC for this

-I changed the name of Vixen to Nalani because # Vixen is taken XD-

More info:

The color of the Nalani effects the elemental power. If the Nalani is Red, It's element would be Electricity. So orange-fire, yellow-light, green-life, turquiose-ice, blue-water, purple-darkness, pink-space. The elements, though, in a mortal Nalani is normally mixed. It is extremely rare to find a true-breed Nalani.

If you have any questions feel free to ask in the comments :)
