Fair, but I reckon you should put a space between paragraphs and do a quick editing sweep. I spotted a few flaws here and there, but am to lazy to go back and point them out.
Celestia, Luna, Cadence, and....Foxtrot? Uhhhh no offense but....HAHAHAHAHAHA
Looking forward to this story, I wonder what the expressions would be on the rest of the Mains' faces when they see someone killed, or worse, FlutterShy killing someone>
...Octavia is a unicorn?
"FoxTrot" does not need to be capitalized as such. Foxtrot or Fox Trot works just as well.
FoxTrot is his name. Much like AppleBloom and other ponies without spaces.
Apple Bloom's name is two words. Why would they capitalize another letter in the middle of the name? That's just silly.
