AU Mane Six

Here is my Alternate Universe idea of the Mane Six, in which Starlight Glimmer was a tyrant who overthrew the Princesses and established an equal republic. (Most AU's sticks to the show)

Applejack: Applejack left Sweet Apple Acres to Manehatten, but is often homesick. After Rainbow Dash preformed her Sonic Rainboom, Applejack realized her true home is Sweet Apple Acres, and immediately packed her things to return to Ponyville. Unfortunately, Starlight Glimmer had started her trek to Ponyville, and Applejack, in her panic, desperately galloped to Ponyville, concerned about her family, getting her cutie mark by the way. (No idea how she ran from Manehatten to Ponyville) Instead of arriving to Sweet Apple Acres, she accidently ran into the Golden Oak Library (Twilight's residence in this AU). Honest and faithful, but often worried about family.

Pinkie Pie: After the Sonic Rainboom happened, the inspired pony threw the biggest party ever, getting her cutie mark. Soon, the humongous Starlight Glimmer came their way. The Pie sisters, Marble Pie and Igneous Pie ushered Pinkie (the youngest in the family of the AU) away for her safety, promising that they will be fine. Pinkie fled, and stumbled across the Golden Oak Library.
AU!Pinkie is as optimistic as Pinkie from the show, but not as random.

Rainbow Dash: When she almost finished preforming the Sonic Rainboom and getting her cutie mark, she saw Starlight Glimmer. Surprised and scared, she lost control and crash-landed right in front of the Golden Oak Library. (Explains the scars and bruises) Daring and brave, and not as arrogant as Rainbow from the show.

Fluttershy: After the butterflies saved her life and she got her Cutie Mark, Starlight Glimmer came. In fear, the animals ushered her away to Ponyville, where she was flew to the Golden Oak Library by the butterflies. Fluttershy calmed the animals down, and as gratitude, critters love to scamper around Fluttershy (especially a few butterflies). Kind and caring, and never scared when he animal friends are by her side.

Rarity: After the Sonic Rainboom was preformed and she realized her destiny, she immediately got her cutie mark. Starlight Glimmer's hoofsteps made the earth shake, spilling the gems, with Rarity right on them. The gems slid her back to Ponyville's Golden Oak Library, and she placed some gems on her mane. Generous, but doesn't care too much about getting messy, but still a fashion forward pony.

Twilight Sparkle: After her magic outburst, Princess Celestia was at the summit and didn't notice her special talent. Mortified of what her powers had done, she teleported back into her home: the Golden Oak Library. (Spike would join her later) Smart and friendly, although she doesn't trust others straight after she met them.

The ponies first met at the Golden Oak Library, where they realized that they had a bond even before they met, and that their cutie marks had brought them together by Rainbow's Sonic Rainboom. They made a pact to stick together, but Starlight Glimmer announced to establish an equal republic soon after, taking away their cutie marks. Starlight ruled Equestria with an iron hoof, often enslaving and treating ponies unfairly. As the six ponies (who stayed at Twilight's for safety) realized Starlight's tyranny, and decided to find their cutie marks and the shards of the Elements of Harmony and end Starlight's tyranny for once and for all.
