Holy shit this was before Equestria Girls

Wow. Whoever guessed this, they were almost right!

@SeraphimDawn  
Personaly i’d love to see the toy department inventing a villan, but this isn’t how Husbro works.  
As awsome as the show itself (and the IDW comics), the toy department haven’t really steped out of G3 when it comes to telling stories with the ponies. how long did it take untill they relised a Nightmere Moon toy? and it was marketed directly at US, being part of a special Toys R Us line of brony favorits.

What’s wrong with toys being villains. From my childhood I’ve always preferred bad guy toys. So are they implying girls won’t like a toy themed after a villain?  
Nonsense, I’ve seen many girls in my elementary school years clutching Disney villain toys.

Not likely… for once she allready got a toy, wich means that there is no way in hell Husbro will let her be evil.

@Shaky
 
Ok, that got a laugh out of me
 
@PonyPon
 
This would be an interesting was of introducing her, should they introduce her

@kleptomage  
A mad scientist/business mogul type villain with his/her own hired and genetically altered legions?
 
I approve!

It would neat to see a villian who is a smart and resourceful earth pony - a Lex Luthor to the more fantastical threats.

Possible. I’m mostly envisioning some tripe, fan fiction esk idea where Celestia has to recruit two more princesses because of that Centaur creature that’s like the embodiment of Hatred. Celestia tries to recruit Discord to fight him, discord being the son of the centaur thing, but Discord is scared of the creature.
 
In the end, the mane 5 come together around the 4 princesses who have to seal away the Centaur creature and Twilight steps up because she know so of a better way. Instead of outright sealing him, she changes things where Hatred is slowly let go into Equestria where it dissipates properly instead of bottling up to where it has the potential to explode.
 
Twilight loses her wings in the process, returning to normal, but due to her sacrifice, Celestia has found “the one” and abdicates her powers to Twilight and the unicorn succeeds her as Ruler of Equestria. Mostly foresee the succeeding of Celestia for a second phase toy line, instead of wanting to follow Faust’s original idea. Though i’m opposed to the original idea to begin with.

how Epic would it be if Sunset Shimmer premiered as a new character in the begining of S4 and throughout all of it was a friends of the mane six acting alittle wierd nothing major, untill the Finale of S4 she dose a complete 180 where everything she had done up untill that point was to complete her master plan of killing Celestia’s newist studant (Twilight Sparkle) and now the five friends of Twilight have to fight along side with Celestia, Luna/NMM, Discord, Shining Armor and Cadence just to stop here?  
That would be tits. o,o

@Background Pony  
I have a feeling that she’ll be motivated heavily by something non-physical. Nightmare Moon was motivated by desire for power, Discord by desire for entertainment, Chrysalis by desire for love, Sombra by desire of sadness, and presumably this one by jealousy.
 
So the “Elements of Disharmony” so far are  
Corruption (NMM)  
Schadenfreude (Discord)  
Deceit (Chrysalis)  
Hatred (Sombra)  
and possibly  
Jealousy (Shimmer)

What if… Sunset Shimmer became the new Nightmare Moon?!

@Kappe  
*looks at the stack of comics
 
She got love. Fuzzy little creatures of love.

It kinda would be cool to have a normal looking pony be a villain

@Kappe  
Especially since Discord wasn’t actually evil…

So they all go to a masquerade ball to celebrate Princess Twilight’s coronation and suddenly this former student Celestia had gets jealous, puts on a disguise, and decides to do her best “Carrie” on it all and only Twilight and her friends can stop her?
 
Sounds good.

Nobody loves Chrysalis.

I’m kind of hoping sunset is a very likeable pony whose only real crime is disagreeing with celestia and bailing on her long ago. I’d like that.

I would be okay with this. As long as she wasn’t some OP generic villain…like some people portray her as.

The real season 4 villain?  
The fandom.

Would be awesome… but sadly no.
