So, I always found it a bit odd that a single Legendary had the power to talk to you across worlds, transform you into a Pokemon, and also transport you across worlds.
So in Evolving Worlds, we've got a squad to do that. Darkrai uses the power of dreams to select a human and let all the Legendaries talk to them. Jirachi scans their aura to figure out what Pokemon suits them best and transform them. Hoopa transports them with portals. And Celebi is the ringleader and basically does all the talking.
First time drawing Hoopa. It was... interesting.
