Julius Caesar was a boss, a leader, even charismatic. Even Stalin had some aspects that could make him seem sympathetic despite all being dictators. I'm rather feeling like keeping her as a cold dictator, without a lot of feelings, besides anger sometimes, treating her population like statistics.
Ponies in this country are into psychic inhibitors(added in every food) as natural reactions, or dreams, or creativeness are considered as mental illness and controlled so. as Glimmer would say, "you can't have a nightmare if you never dream." I really want to keep her as a soulless monster, a machine that only reasons with a determined plan and logic, with a brainwashed population that considers this perfectly normal.
