Top notch stuff apart from those.

MERCENARY
 
CODE NAME: Pinkamena
 
FILE NAME: Pinkie Pie
 
PRIMARY MILITARY SPECIALIZATION: Covert Operations
 
 
After the war with King Sombra broke out, Pinkie Pie was complete overtaken by her split personality, Pinkamena. Despite being a sinister psychopath, Pinkamena doesn’t want to see Equestria ruled by King Sombra, which is why she joined G.I. Joe. Pinkamena proved to be a valuable ally, as her superhuman strength and no-nonsense attitude makes her a force to be recknoed.
 
“No more cupcakes. No more silly parties. I will find every Pony working for King Sombra. I will find them, and I will kill them. No matter how long it takes. After that…we’ll see.”

So where’s Maud?
