Awesome: My Little Pony: Friendship Is Magic (IDW)
As of one and a half months before the launch, pre-orders for Issue #1 have already exceeded 90,000 copies, out selling the likes of Uncanny X-Men, Spider-Man, Green Lantern, and Detective Comics. In a medium that has lost touch with children and non-superhero fans, this is a valuable development.
Now they sold 100,000.
For all single issue comics sold in 2012, the first issue came in at #90 on the best sellers for the year. May not seem that impressive but consider that it, along with The Walking Dead #100 (which came in first), were the only two non-DC, non-Marvel books to break the top 100 list, and was IDW's best-selling book.
Individual issues of both the main and micro series continue to be in the top 100 of single issues sold each month through June 2013 (the Fluttershy micro so far has been one to fail to do so) and continue to be IDW's top selling series.
The Return of Queen Chrysalis
The changeling fight in the first issue has some great moments.
Chrysalis: Stop...this...nonsense. You can't...defeat me. Twilight Sparkle: Ponies who can't do things themselves tell others that they can't do it... I can stand up to you. And I can win!
And then, of course, there's the fact that she was able to duel Chrysalis, a villainess who was on par with Celestia, on equal footing. Not to mention that she was able to WIN!
Of course, as the Season 3 finale reveals, she was destined to become an Alicorn. The magic-boosting comet may have allowed her to tap that infinite potential.
And prior to all that? When Chrysalis first sees how the power-enhancing comet has given Twilight a boost that makes her magical blasts extremely devastating, her wide-eyed reaction is epic.
Chrysalis: How...did you...?
Which really ties into how she was able to defeat Chrysalis. They both received power from the comet, but Twilight knew how to use it, as opposed to Chrysalis, who tried to just take it. Chrysalis lost because she really didn't know how Twilight was able to use the comet's power.
All the epicness Spike and Celestia (and Luna, but not as shown) were up to that prevented them from helping sooner. Few things in this world are as glorious as the image of Spike, with an eyepatch, riding Celestia into battle with giant magically enhanced cockatrices.
Spike: It was awesome. I had a trident!
Nightmare Forces Arc
The Mane 5 overcoming their fears on the moon are all awesome in their own way, but Pinkie Pie gets a special mention by overcoming her nightmare through pure ham.
Pinkie: I am the MOST laughter-giving, fun-having, friend-making pony ever! YOU HAVE NO POWER OVER ME!
And, showmare that she is, follows up with a mic drop.
In Issue #7, Spike overcoming the dream made by Nightmare Rarityon his own.
The preview cover of Issue #8: Luna in golden armor leading a Big Damn Heroes team that includes the Wonderbolts, Derpy, Big Macintosh, Doctor Whooves, DJ Pon-3, Trixie, Lightning Dust, a Day Guard, a Night Guard and Wildfire.
And the issue itself delivers exactly what the cover hinted at. Most of the characters have their moment whether it's taking on the Nightmare Forces or bravely standing side-by-side with Celestia and Luna. Probably the most notable moment has to be when one of the Nightmare Forces hovering over a helpless Angel Bunny only to realize too late that he fell into Angel's trap with the help of the Cutie Mark Crusaders (Including Babs Seed), Cheerilee, Twist, Snips, Snails, and all the mane six's pets.
Or perhaps Granny Smith showing her martial arts skills, or Octavia going all El Kabong with her cello.
Since the beginning of the arc, Luna has been consumed with sorrow and fear that she will fall to the dark side again. How do you know she means it when she says she's truly gotten over her fear? For the first time in the arc, she transforms from her Season 1 appearance to her Season 2-onward appearance. Simple, yet awesome.
Spike managing to Out Gambit the Nightmare Forces into leaving him behind to free the mane six by making a dummy of himself out of moon slugs.
Zen and the Art of Gazebo Repair
No challenge is too great for the pairing of Luna and Big Mac!
Celestia beating Big Mac in a hoof-wrestling challenge.
Shining Armor's band's performance gave Vinyl Scratch her cutie mark, it was that epic.
Admit it, the way Buck was taken down a few notches, in front of the whole dang academy, was bucking AWESOME, and SUPREMELY satisfying. Bonus points to Shining Armor, since he was the one to deal the final blow to Buck's ego.
My Little Pirate - Friendship Ahoy
Rainbow Dash shows that if she was a real pirate, no one would be safe, as she easily disarms a whole group of them.
A bit of a meta-example: we finally get to see Star Swirl the Bearded, albeit in flashback form...and it turns out that he was Celestia's confidant!
King Sombra is shown at the end of the first part of the arc.
