The Sons of Anarchy arrive in Ponyville - ponified and on motorcycles, because fuck logic - and decide that Equestria needs a bit of the outlaw edge. It’s the Mane 6 vs the Sons for the soul of Ponyville! Pick your side, take them down the moral roads and see who lives and who becomes an abomination!
Rock/Paper/Scissors for fights/plans, of course. XD
