Luna the Great of all the Russias

Princess Luna is a great Princess IMO

I've said it before if I were a pony living in the fictional world Equestria, I'd support her, I'd like to be her friend, she has something in common and it is more than her love for Halloween-esque festival Nightmare Night, the way she treated Cutie Mark Crusaders was endearing, boosting their confidence even when they were getting bullied for not having cutie marks by other Ponies. Luna is definitely somepony I could see myself having a great time with. I know she is a Monarch, but as established it's more important that Rulers have ethics than anything else. It's entirely possible to have bad Rulers who were elected, like in real life, who commit war crimes. Given the awful politics of the real world, I'd much rather have Luna as Ruler.
