Who's that Pokemon?
It's Iraby! (Eye-ray-be)
PSYCHIC | FLYING
Iraby is still young, so it protects itself in a cotton cloud. When a rainbow appears, Iraby is said to be close by. When the cloud expands, it is close to evolution, and will hibernate above the ozone layer. It is a messanger for the legendary rainbow Pokemon. As it flies, it sits upon a mystical golden table; it protects it from danger in a pinch.
Idea inspired by Iris of Greek mythology. :)
