No. Just. No. You have a Mesperit named Sprinkles and is Arceus' mate- have it all the pokemon, legends at least are born from them. You then have them find a special egg, that fell from the sky, and the pokemon that hatches is even more special.
I mean you're belittling god pokemon here in more ways than I can count. Ok not really but still. It's bad. Just, bad.
I would try and offer a suggestion but I am writing a story.. somewhat simalur to this- but with less eggs falling from the sky or wierdly named legends. You should think this out more- especially if that short, rushed and flat paragraph was an example of your chapter.
@ Dragon Tamer
I suggest you read Stephen King's The Stand or The Last Stand, whichever it was named. Or watch the mini series, I am sure there's some of it up on Youtube or Netflix. It deals with lone survivors of an apocalyptic disease/virus hitting people and killing off nearly the whole population of the world- or atleast america. Animals included.
A virus has hit all of pokearth; no one knows what it is all the remaining survivors know is it’s happened. Everyone who has had the virus has now died. Now following one survivor, a trainer, who had been in Shinnoh but cant escape and go back to Johto to find her family.
Because I don't think you really understand the horror that would also be in the story of your idea.
