Evil Twilight is absolutely fantastic.
 
And I love how one of the steps in her evil plan is just “Gloat!”

So, does this mean Twilight can calculate every possible outcome that doesn’t involve humor?
 

 
Twilight is DC’s new Midnighter!

:holds an ax behind the door: … what did you do to my goddess nightmare moon?

She has reached the singularity

If this is the smartest ever that Equestria can offer, I may try my chances in Griffonstone

The setup to a worthy boss fight.  
…please?

SO CLOSE TO EVIL GLORIOUS TWILIGHT…and then the next page happens…sighs

Also, it’s scenes like this and the cover of issue #53 (“…including this one!”) that make me think that Fleecs has trouble getting ponies’ faces to adequately convey a feeling of “oh crap”.
 
Unless they already know about the trap Pinkie has waiting behind the door and are just pretending to be shocked and scared.

So this is the origin of the “evil twilight explains” tag, but it itself doesn’t have it.

No.. it’s just the 1st year of school

I wonder if he says that about all of his plans.

You let Equestria down!

Twilight Sparkle would make a pretty scary villain.

To paraphrase Hank Hill: “That [girl] ain’t right.”

“I’m not some Saturday morning cartoon show villain. Do you think I would explain my masterstroke if there was even the slightest chane you could affect it? I set it off 35 minutes ago.”

“Equestria’s second smartest pony can no more hurt me than its smartest termite.”

As usual Sweetie Bell is the only one to like whatever horrible spectacle is occurring.

I love how gloating was all part of the plan.

“I’m disappointed in you, Twilight. I’m very disappointed. I have walked across the surface of the sun. I have witnessed events so tiny and so fast, they could hardly be said to have occurred at all. But you, Twilight, you’re just a mare. Equestria’s smartest mare poses no more threat to me than does its smartest termite.”

>smartest pony in history
 
Boy, is that a sad thought.
