I could use 5 characters here.
First, Twilight Sparkle: I can feel her very much, task-oriented, constantly on the move to learn stuff, prefers to deal with problems with strategies and cunning yet often greatly pained to dissapoint loved ones and quite workaholic. Responsible albeit often quite out of blue with mundane details.
Second is Sunset Shimmer: An ambitious, originally arrogant girl who after being taken down a peg is now compassionate, yet like Twilight it’s pretty task oriented, aggressive yet very mindful and quick thinking and a great gamer. Plays to win and enjoys the idea of constantly develop new skills, though also quite irritable a lot.
Third is Celestia: Always aiming to save everyone around me, having a warm predisposition though covered with professional aloofness. Sometimes burying a lot of past pains just to keep going despite everything. I also like the idea of tricking others because sometimes is just fun to see how the events could develop afterwards.
Fourth is Discord: This one it’s more like an inner demon rather than active actions. Beneath all, I’m prone to have spiteful thoughts for a lot of people and I’m often tempted to just play mind tricks and rub the feathers of people I feel no respect whatsoever, only kept on check to make sure I don’t make my life or everybody else’s life any more difficult. I also like the idea of being able to achieve whatever I want without any limit (like his chaos powers).
And finally Rarity: Often self-centered, ocasionally greedy for my own sake but also willing to lend to others if I feel they deserve it. I like to be as artistic and I could be quite picky at eating or hobbies, but I also like to use tact over brute force most of the time.
