Always kinda wondered why the Rocket Chant starts with "To Protect the World from Devastation" technically "Uniting all peoples" isn't a bad thing either, just the part where they plan to be overlords over it all
If I remember right, that's just the TRio screwing it up, Butch and Cassidy had a different one.
I wouldn't mind if they pulled a Platinum and had the main legend arise non intentionally, but rather, as a consequence of the evil team's strife. What I wouldn't mind, if we go back to Kalos, that the Evil Team does something after you beat the league which angers the legend of the game? Either the sun legend creates a source of light for the other side of the world permanently making it daytime, or the moon eclipses the sun and locks the world in darkness in Sun.
The legend has sealed itself somewhere, where you then go to Kalos to search out Zygarde. The evil team in the meanwhile has learned their lesson and is attempting to help you, but find themselves hindered by their rep. You get the Kalos badges along the way, entering Snowbelle through Santalune, nabbing that badge and running up to Termius Cave. Either Anistar is the last gym, or the route is blocked off from Anistar. You get there, and get Zygarde. Alternatively, you collect/befriend cores through the game and unite them here. You might not actually catch it, you might just set it off to start acting. Zygarde goes Complete, we get an epic cut scene along the lines of BW2. Legend gets weakened, you fight it and either catch/capture it, and away goes Zygarde if you don't catch if.
If we aren't returning to Kalos, the exact same thing happens, but after the 7th badge. Instead of this game's legend, it involves the opposite mascot. You seek out your mascot, which is somewhere around the eight gym. You then go and attack the opposite legend, maybe in a solo battle with it. Evil team leader/admin/whatever captures the weakened legend or at least tries to, where you have an epic final battle on some mountain or shrine or temple.
