@Prof.NightJack I headcanon that she is basically Cheerilis, because wouldn’t that be the closest canon approximation to her opposite? A teacher of her changelings that thinks they can pretty much do no wrong, who believes in ‘corrective reinforcement’ over violent means or righteous powerbeam battles,who treats them all as one huge Apple family unit.  
I must say I DO hate that they don’t state who they’re fighting against because Evilestia doesn’t seem to have any sort of army whatsoever.

Reversails: Hey Chrysalis!  
Chrysalis: Yes?  
Reversails: Did you like to be my..sister?  
Chrysalis: Uh okay?

Even she doesn’t make an appearance this time, I hope that IDW doesn’t leave this mirror universe behind after this story arc is done.  
They can revisit this wonderfully backwards world again, right?

Good Chrysalis: I love you~
 
Evil Chrysalis: i hate you!
 
G.Chrysalis: Love you!  
E.Chrysalis: HATE YOU!  
G.Chrysalis: LOVE YOU!
 
E.Chrysalis: Buck you  
G.Chrysalis: You too~

@RIG  
I figured she wasn’t going to,I was just wondering if we would be giving some info one what she is like.
 
@PonyPon  
Well how about what does she and the changelings do for food? How is she nice, is she like a loving grandma?

@MeshGearFox  
How?

Oh crap I just realized that like Good and Evil Chrysalis is like the Derspit and Prospit version of Vrichika from Homestack.

@Prof.NightJack  
Look at her.
 
She’s nice.
 
What more do you want?

@Prof.NightJack  
she will not appear, Good Sombra said she is busy protecting southest Equestria.

We got any word on what she is like yet?
