Well, she’s already caused a few riots, ruined a performer’s reputation, destroyed Ponyville, turned her own parents into plants, had a psychotic break, given children a poison recipe, caused an information paradox, deposed a foreign leader and replaced him with her sister-in-law, terminated several dozen possibly sapient beings, warped her friends’ minds, mutated a friend, gave that same friend’s indentured servitude royal approval, and effectively killed three immortals.
 
I’m not saying Twilight’s evil, but her actions and the reuslts thereof haven’t always been positive. Of course, the same could be said for any adventurer.

Yes, Twilight Sparkle, the main character of the show, the pony who we are meant to project ourselves onto, will turn evil.

@SeraphimDawn  
Agreed, agreed.

Something like this needs to happen in the next EqG movie. Or preferably, the show as pony of course.

You know, I kinda wanna see “Justice Lords Mane 6” now.

Corrupted pony Twilight, or human Twilight who’s pulled an Agatha Heterodyne?
 

Remember, kids: when girls become evil, their body temperature rises to the point where they need to wear less clothes.

Beta Midnight Sparkle design. ;3

Warrior Princess Twilight, hmmm?  
Approved.  
>;)
