So the idea of the villain being some lost forgotten brother of the Royal Sisters called Cosmo (Cosmos?) was initially floated before finally settling on the Storm King/Tempest due. I admit, I get a kick out of the idea of introducing a never-mentioned brother, as I just imagine the epic meltdowns from very unreasonable bronies and those that take the canon waaaaaay too seriously.

Generally, would I have liked it? Not really, I wish they had just kept the Sisters as the only alicorns and made Cadance a Pegasus Princess and Twilight a Unicorn Princess, and later find an Earth Princess. But would I have liked to have seen a male alicorn, if they had decided on that design? Heck yeah! Would I have liked it in the main MLP show? Again, not really.

What about you? How would you  have reacted to a new, secret (and evil) brother for Celestia and Luna? Do you think the fandom would have had a meltdown?

Twilight: How could you have had a brother I didn't know about?!?
Luna: You're one to talk
Twilight: ... okay, well, yes, you have me there. But still!! I know what Celestia had for breakfast 359 days ago!! It was toast with marmalade and blueberry jam!!
Celestia: ... Backing away, backing away slowly now

A brother for the sisters would actuallu be a more reasonable surprise than one for Twilight, given that their foalhoods were swathed i deep misteru. Of course, a lot would depend on how he was introduced and what we learned about their past.
