"WIll-o-Wisp with Giratina- A large ball of blue flames instead of mini balls Actually medium sized balls that are black could work"

Will-o-wisps tend to take on a blue flame appearance in almost every legend and our media related situation...

so i think we can stick with the light blue flame ball theme also that would pretty much be the same as shadow ball or such...
