Well, this Nightly Megathread was going to be brought to you by our fair Deputy Derpy, but his internet is being...well...derpy. So I offered to cover for him tonight. And I absolutely love this image. Have some on-the-spot nightly after the break.
I feel in a very villain-type mood today, so I'll base the discussion on that. Say all of the villains/antagonists of FiM banded together and sought to wreak havoc upon Equestria. How would that all go down? How well would the mane 6 and the rest of Equestria fare against such an onslaught?
