This is me and my Yveltal, Death Wing. I became his friend whenever he hatched from his cocoon. He is very loyal. Though he may look scary, he is really a sweetheart. He cares about other dark and flying type pokemon, and he protects flying types from harm.
Umbreon was designed to be light in the dark, and this concept art captures it as the viewer can see a glowing yellow with a glossy black. The yellow shapes are so very solid rings but the rest of its body is uneven and graceful in shape.
