1. She’s a unicorn, and unicorns are naturally cool.*
2.  She’s purple, my favorite color.
3. She has a big ol’ brain. Anyone who studies magic and science is OK in my book!
4. Prior to moving to Ponyville, she was an anti-social recluse. I can relate.
5. That mane and tail. You’ve just got to love the streaks.
6.  She’s voiced by Tara Strong.
7.  Until recently, she lived in a tree house with a magical lightning rod so’s not to get struck by lightning. Now that’s thinking green!
8. I just plain like the name “Twilight Sparkle”. It rolls off the tongue nicely.
9. She has purple eyes.
10. She has mad organization skills.
11. She hangs out with a dragon, which makes her cool by association.
12.  She’s got that bitchin’ cutie mark.
13.  She was mentored by Princess (should be Queen) Celestia, babysat by another princess (Cadence) and her brother (Shining Armor) is a member of the Royal Guard, so she’s connected.
14. Her Element of Harmony is Magic. The other Elements are OK too, for the “hippy-dippy” stuff, but magic can actually kick ass.
15. She can do the Elaine from Seinfeld dance.
16.  In an alternate reality, she looks like this:

You’ve got the look!

*Yes, I know that Twilight Sparkle is an allicorn now, but honestly, I prefer Twilight before she became a princess. I think that the whole allicorn princess thing should have been saved for the series finale, but that’s just me.
