For some reason, I have this mental image of a human clad in Navy SEALS armor and one of those creepy gas masks with red lenses towering above them. Not sure why, but it seems to fit for some weird reason.
something tells me it isnt a monster based on the amount of ambient light cast directly on them in a small circle. the first thing that came to mind was some large machine or vehicle with bright spotlights turned directly on rarity and sweetie. thats just me though.
