Question what are the plan for Arceus changing into other types with the plates? She was not in the AWC meeting with Giratina though if she was to go to AWC she would ask Lugia for a private lesson to not embarrass her daughter and make Giratina say something like "kill me now I'm about about to die of embarrassment" after seeing her mother present her but for the class to see. Plus Lugia would love to get her hands on the ass that all other asses are modeled off of. Plus when she can turn dragon type for her massage later on.
Also had a bit too complex but really funny idea of at the end or past gen 7 region when the MC wants to walk around the city/town and all the legends decide to follow him around and all the citizens think its a parade to the legendary Pokémon seeing giants and goddesses walk around following the MC since he will have so many legends caught by then. I know this will be a bit to complex to put in but is a way to show how big his harem has gotten by then.
