If I make a summary of everything I put in the backstory, it'll sound disrespectfully requesting (which is forbidden in here) and it'll make her seem to be an unfair Uber alicorn pony. But since you want it, here it is:
My little pony is an alicorn whose name is ME. Her name always has to be written in capital letters only, even if the rest is written with small letters, only. "ME" is not the short form of anything. Her name is pronounced just like "me". ME is able to talk to humans. She is able to vomit without dying immediately afterwards. She can hover and teleport multiple objects with her horn at once. When making herself invisible, she can stay invisible as long as she wants. Whenever teleporting anything, it can only be teleported through free space. Glowing her horn always produces light and warmth. She can burst balloons by hitting them with her horn. She needs her horn to only hover bigger/heavier (I'm not sure) objects; for smaller ones, she doesn't need to make her horn glow. If Discord ever took her horn away, she'd still be able to hover small objects. Anything which has anything to do with teleporting still requires her horn. Her front legs have thumbs she can use to grab things. They might even be hands. She has a less mass than ponies without wings but can still carry as much weight as them. She can walk on clouds. She cannot fly if it's too cold or if her wings are too wet. If you ever shave this pony's mane, it'll grow back, immediately. This does neither apply to her tail nor to her coat. If you make a cape off her mane, it'll be a cape whose wearer can perform magic spells by saying magic spells.
ME is a flashgame pony who comes out of this game:
Just like all ponies in this game, she wasn't born in Ponyville but still in Equestria and moved to Ponyville to get her cutie mark. And just like all ponies in this game, she has some enviably flashgame powers. She never has to eat, never has to drink, never has to go to the toilet, never has to sleep (which doesn't make her immune to Jigglypuff's Lullaby or whatever it's called which is why I sprited it), never has to wink and never has to move. She could stand/walk/trot/gallop for unlimited time without ever getting tired. Walking is just like Granny Smith's walking ability and gallopping is just like Applejack's bucking ability. Also, she doesn't age, making her able to live for unlimited time.
When playing Applejack's minigame, ME often kicks the appletrees before the apples reach their full size so she doesn't lose any points. When playing Pinkie Pie's minigame, ME often purposely throws all sweets to the bottom so Pinkie Pie has to replace them, ME can give her sweets and Earn more Friendship Sparkles.
ME does not wear any glasses. The thick black line around her eye is not an eyeliner. It's a bunch of eyelashes, all with the same length and perfectly evenly spread.
When ME's wings are closed, they look just like any other pegasus' wings. But when they're opened, they're giant because they are folded 8 or 9 times. They'd need an own GIF file, just for opening and/or closing. ME is also able to perform a quick slice attack with one of her wings, no matter, if they're closed or opened. I cannot sprite her wings and need help.
ME also has the abilities to duck, dig, jump, fall (If she falls on someone, it'll deal damage, similar to Mario's jump.) and swim, all abilities I didn't have any templates of and 'd need help for, too.
If me ever gets DISCORDED, she turns into those animations which begin with "not ME". She smokes and drinks and makes it with everyone. Whenever she does not make it with anyone and finds a make-up tool, she paints her lips and her nails/hooves. I didn't sprite that because she takes whatever colour she finds, although it's preferably red. It'll be the exact opposite of her real personality because she doesn't smoke, never drinks anything alcoholic and also is disgusted when abounded. And she thinks red doesn't fit to her. The only thing her and not her have in common is that they don't have anything against cloppers, as long as they don't purposely film themselves clopping.
The SSBP palette is just the same as her opposite. I sprited every move because she has still the same abilities. The reason for her look is some kind of technology which can turn a person with a split personality into two persons. Although ME doesn't really have a split personality, her SSBP sprites should still be used if she ever gets imported into some kind of "Super Smash Bros. Ponystyle" which includes many recolours in case more than 1 player selects the same character. SSBP is for ME just like Wario's other suit for Wario in Super Smash Bros. Brawl. The abilities are just the same although SSBP might look more authentic with drinking/smoking idle moves I'd also need help with. As you can see, the whole folder doesn't include bottle sprite as in Berry Punch.
The only things which aren't inborn are ME's earballs , SSBP's flowers, SSBP's lipstick and SSBP's nail polish. Yes, she has polished her nails/hooves red which you can't see because her nails/hooves are hidden under her coat. And because I couldn't sprite them.
