Still think she would be a Dark Angel player for the robes alone.

I remember^^

@infinita est lux Solis  
You’ve already got one….
 

@Background Pony #4758  
Tech priests didn’t even have models or rules when I drew that.
 
The others suggest corruption. Which doesn’t fit with the Mane 6.
 
Ultramarines like to work ‘by the book’.  
(Although Guilliman has stated the Codex Astartes requires updating).

Not a Techpriest, hoarding all knowledge for the glory of the emperor omnissiah. Or a sorcerer from the Word Bearers bringing the good book to the masses? Or a chaos sorcerer wielding forbidden arcane knowledge and godlike powers?

The power of my glorious Lord Tzeentch shall take this pony in the name of CHAOS!

@Celestia’s Servant  
I did a lot of the characters ages ago.  
Rarity I think was the first.  
I tried not to repeat forces, so everyone had something different.  
Applejack-Guard  
Rainbow Dash-Dark Angels Ravenwing  
Twilight-(what else?)Ultramarines  
Fluttershy-Tau  
Pinkie Pie-Orks (had to be really)
 
Trixie-Thousand Sons  
Sunset Shimmer-Chaos Daemons  
Queen Chrysalis-Tyranids  
Celestia VS Luna-Grey Knights and Night Lords  
Discord-Chaos Undivided. (Also had a D4 and a D20 in his dice pile to show he wouldn’t play fair)  
King Sombra-30k World Eaters (This one was a request)  
Lightning Dust-Dark Eldar  
Spitfire-Angry Marines (I should feel bad for that one but…)  
Maud Pie-Necrons  
Gilda-Space Wolves (Also works with Dash’s Dark Angels because of the rivalry between the legions).
 
I think that’s all I did.  
I did plan on doing Scootaloo using White Scars at one time but never got around to it.

Rarity play Eldar, hm? Let’s see how she does against my Chaos forces.

You certainly improved. Especially in terms of anatomy and shading. Her ears could be a bit bigger tho.
