It is a patora fusion between rainbowdash and a shiny umbreon which is essentially a perfect combining of the two. So main traits are loyalty, protectiveness, though a bit misunderstood at first due to darker appearance and quiet nature around new people, but once they get to know you, super outgoing, jokey and playful. Umbreon tends to have a moonlight type of theme, while rainbowdash has a rainbow theme. I had the first artist go with a low spectrum rainbow theme for the hair that I thought turned out well, though if you want to tweek the color scheme a bit i am down for seeing other takes on it.
