First of all thanks to for letting me use her CPA versions of the Humane 5.
There's the thing I've seen her and Xeck made Crystal Prep versions of the Huamen 5 and Sunset and they're just characterized as jerks like the Shadowbolt 5. Now while I can like the Canterlot High versions of the Shadowbolt 5, or at least their designs, I don't like their version of the Humane 5. First, while I like the Shadowbolt 5 I can't deny they were pretty weak in The Friendship Games, only Sour Sweet and Sugarcoat got a chance to show that they were meant be like negative versions of their Humane 5 counterparts. And the characterization of these alternate versions of the Humane 5 reflects this with how their just jerks and that's it. That's my problem with mirror universe scenarios, they'll just take a character that good and make their counterparts just evil and that's it. Heck, the Reflections IDW comics is great example of this, it was just good and evil and flipped around and there wasn't anything to other than the Good version of Sombra and his relationship with the main universes Celestia, it's one the weakest arc in the comics because it didn't do anything new with the mirror concept.
That's why I did concept art of this alternate universe idea: the humane versions of the Mane 6 all go to Crystal Prep and come together as friends to change CPA for the better.
