So i have recently seen that you have started removing Bowser's image and replaced it with a new one, to make sure that we're on the same page, i want to tell you that i had an agreement with user B1bl1kal earlier about the current image, and we would appreciate if you wouldn't remove it, thank you.
Daybreaker maybe a figure from Starlight's dream, but she acts antagonistic and Celestia was bound to have an alter ego, just like Luna with Nightmare Moon.
Since the Talk page for Daybreaker was deleted along with the article, I'm responding to your comment and concerns here.
"Daybreaker" does not qualify as a villain here because she is an UNREALIZED figment of *Starlight's* imagination and nightmare. Which means she DID NOT REALLY EXIST. And as such "Daybreaker" IS NOT TRULY CELESTIA'S ALTER EGO… she is Starlight's FEAR that is what Celestia might turn into.
Therefore she no more belongs here as "Midnight Sparkle" does.
Nor, in fact, does "Nightmare Moon's" actions in this nightmare equate to *her* actual actions.
PERSONALLY, I don't even think "Daybreaker" qualifies as a true antagonist, but I don't make policy for Antagonist(s) Wikis…
