This mysterious Pokemon has an alluring, ethereal presence! Its body is light blue, with two long, pointy appendages floating above it. Its eyes are large and black, with a white star-shaped mark on its forehead. Its body is slim and appears to be almost translucent. On either side of its back, there are small, delicate wings. If I were to color this ghostly Pokemon, I would shade the blue a bit darker and add some white highlights to create a ghostly feel. I'd also pick a golden yellow to color the star on its forehead, as well as its eyes, to add a bit of warmth and contrast. Adding golden tones to the appendages can also help bring out their spooky presence. Finally, adding a bit of light grey to the wings will help them stand out from the body and the background.
