Dear Celestia, I'm starting to think you all don't appreciate my opinions! XD I am doing my top six favorites because of the Mane Six.
6.) Lyra and Bon Bon
Even though these two aren't canon as being friends, I see them together a lot during Season one. Nothing that I know of in Season two. Lyra and Bon Bon are seen walking together, talking together and basically hanging out. If these two weren't background characters, I think they'd be the best of friends.

5.) Rarity and Fluttershy
I just love Rarity and Fluttershy! They are the best of friends! Can you believe that they hang out every weekend to go to the spa and spend time together? How adorable! :3 I also love how they treat each other with a slight hint of respect. They are both pretty girly as well.

4.) Rainbow Dash and Pinkie Pie
This friendship pair shares many differences and similarities. Such as, they're obsession with pranks and laughing. The down side of having these two as friends is that they could get into some fights. Like Pinkie Pie, one could get jealous of the other's friend. But these two can't get any funnier and nicer together. I for one love them as friends.

3.) Twilight Sparkle and Pinkie Pie
Twilight is a very studious pony and Pinkie is totally hyper all the time. It's like these two could never be friends. But I realized in Feeling Pinkie Keen that they fit together perfectly. They care about each others feelings and understand one another.

2.) Diamond Tiara and Silver Spoon
I know some of you despise this pair because of their snootiness and bullying. But I love Diamond Tiara and Silver Spoon as characters and as friends. I actually think they are perfect because of their personalities. They are both mean, and love to make fun of blank-flanks such as Twist and Apple Bloom.

1.) Apple Bloom, Scootaloo and Sweetie Belle
Since these three are blank-flanks, they are best to be friends together. They all share many interests in finding their true talent. The Cutie Mark Crusaders really understand each others' thoughts and why they should be able to get their cutie mark. Even though they are different in many ways, they still add up to be an amazing group.
