A drawing of Flashwing and a generic shiny Shaymin somehow getting conjoined, then looking at each other with a surprised expression, followed by their conjoined bodies fully merging (like colors fully mixing, Flashwing's other wing appearing on the Shaymin side, etc), then their heads merging. As well as keeping both of their normal quadruped body type. (where they fully merge, including their heads).
