Beelzebub (King of flies/Prince of gluttony)
Mammon (Prince of greed)
Leviathan (Princess of envy)
Belphegor (Princess of sloth)
Satan (Prince of wrath)
Lucifer (Prince of pride)
Asmodeus (Princess of lust)

There are a few obvious ones such as Leviathan being a Leviathan but I just want some opinions.

I think lust would be changeling, while pride I could see as an alicron, greed be so dragon, sloth I can see as a dragon as well, gluttony would just be pinkie pie....... other I don't knew

5462810 wouldn't Beelzebub be a changeling aan greed, a diamond dog? Those mutts are greedy little bugers

changling are more hunger for love or lust in my eyes,
diamond dog would be good choose for greed I forgot about them,

5462904 I think alicorn would be sloth. If I had the magical power to doing anything I want, I'd be a lazy ass too. Maybe dragon or griffon can be pride.

5462904 the real problem is anger. I can't think of shit for that guy.

I can think of two, dragon when they piss or old King sombra or what ever his name is,

pride would be dicord, not sure why
